im thinkin on goin with a holset hy35 (8cm exhaust hsng) on the tdi...its reasonable dough......go big or go home? good idea yes/no?
oh also, its in centerburg, i know a few diesel guys are near there.where ya' at??i could stop by for a smoke :lol:
-
Centerburg Ohio? Just down the road from here! ;) Hit me up if you get it, I'll help you drool on it. :D

hopefully i can get a hold of the guy and get down there this weekend....think itll make the tdi-m a runnin fool?????
-
ijust talked to the turbo guy,,im gonna be in centerburg by 11 am this saturday
then im clear for some vw shenanigans,lord
then we can drool on it :D
-
DO IT. I have never seen an 8cm exhaust housing normally I think the hy's are like a 9cm, I would look for even a smaller one like a 6cm housing as you are just running a single, if your turbo guy doesnt have a line on them give Piers a call or Garmon.
I have been pushing the Hy/Hx-35 for like 2years now, and people are just starting to catch on, but at least they are :P .
Post up when you get it.
-
i think the printout rabbittree gave me said 8.5 they make a 6??wow,well maybe someday if i had the $$ for that 6cm,but for now,it kinda hasta work,ihope :? :? :roll: :?: ,at this point i figure i aint really worried about lag,etc,
it is already on strong(boost) at 2000 rpms now,so big deal if it doesnt come on till a little later,,as long as it kicks the stock turbos butt when it chimes in :twisted:im an amatuer at reading a turbo map,can someone look at the 2 and compare?

the main dude used to be a vw tech in the mid-late 80s ,i drool at his stories :P
-
hows that thing run andy2???looks like a beast big thumbs up :twisted: :twisted: :twisted: oh,ilooked at the big pic,do you have it goin yet???man,thats gonna be wicked,ohgreat,,now look at what you did,should i stage it??,not yet ,i just wanna get the swap done before waterfest,so down the road,maybe
:twisted: :twisted: it never ends,it just gets smokier
-
I actually just heard the engine run for the first time only an hour ago :D.Starts right up no smoke at idle (18-19:1 CR),sounds great.Theres just enough to make the hy spin at idle :twisted:.

lord verminnard,you are gonna miss out,cause im comin your way in a few hours :cry: ,im leavin in about 20 mins :wink: maybe next time :cry:

here ya go,thats my stock blown up garrett on the left

how can this thing spool up? :shock:

that exhaust side is actually pretty small,,ill have to get more pics :wink:

Rock out with your "Holset" out! 8)

YUM....
your lookin at my winter turbo, want to do it instead of the larger garrett I have for this year but the funds weren't there for a good unit :( ....unless of course you can find me one for a nice price! It'll be great to see how this performs!

-
Custom manifold or not I wouldnt try running anything bigger than like a .48 turbine, for the first turbo, I know holset doesnt measure their turbines convetionally but that looks like it would be in the neighborhood of .63 plus. Looks like a great candidate for sitting on top of that garrett :twisted:
-
but ill keep blowin up stock vw turbos the way i drive it,,and i dont mind some lag because it has like none now,cause i think the stockers are too small,we'll see,i dunno,i stopped by the manifold dudes place today,its gonna be fun,not too bad though,if we "engineer" the manifold right,ill be able to use it for future stuff,like staging,etc...
its like,it may really suck,but im willing to try it to find out,i sorta dont care how it drives,as long as it hits solid 13's all day without blowin a turbo to smithereens,like i already did on my new engine ,and i almost poopie'd myself
(http://img62.imageshack.us/img62/9568/hpim03494jy.jpg)
the cast exhaust outlet/wastegate cover is like 2.5,and it flares up to 2.75,before hooking to an exhaust pipe
-
REALLY interested in your results, as I'm pondering using a stupid size turbo as well with a M-TDI. Even toying with super-turbo combo but we'll see. ;)
When you putting it on? And who's making your manifold? :D

Its about a .53-55 iirc sombody once mesaured it. You will never blow that turbo, The motor will come apart first. I have witnessed guys pull 375whp with redicoulous egt's on that turbo (they both had upgrades standing by and were trying to see if it would go boom, with redicoulus fueling) the one truck swaped to an PDR HX-40 on the same day, nothing else changed and dynoed 490whp so you know he was well over fueld :wink:
Run it on its own. You probably won't start making boost till about 2850-3200rpm, but it will come on strong after that so hold on. :D Let us know how it goes, 13's will be there if you have traction :wink:
If it really is having a tough time spooling hit it with a shot of n20 and you will never look back. :twisted:
-
tha freakin stock turbo is on hard at 2000,,,, so if this one is 2800 or so that aint bad,,,,that will be livable
heres the manifold fabricator,does way awesome work,and used to be a vw tech back in the mid-late 80s
if its a runner,i wont bother staging it to another turbo
http://westmotorsports.biz/
heh,traction? do you see what i got? what traction,ill just use a honda for traction under my front tires :twisted:

Blake man i have my ride in the garage i mounted my manifold it is a A3 2.0L gassser 4 into 2 mounted upside down..i have fabbed up a flange from some steel plate and i have my hy 35 off and almost ready....its soaking in pb blaster so i can adjust the center sections etc..i don't have a big enough snap ring plier set to clock the cool side argh..... i have go borrow or built one....alos i have a idea to disable the waste gate ..i think i will drill and weld a nut to the bolt on down pipe plate that allows a bolt to thread through and push on the waste gate poppet to keep it shut...it it works well then i can cut off the waste gate aluminum bracket on the cool side and mke more room...i think it will work fine shut off all the time as this is a tiny big for this engine..what do you think?.... I hope to have it done by next week.. hopefully i canget the trans built too quaife - 367 r$p..and your cv cup springs...i am also swapping to a gasser pass side engien mount o run the a3 tdi injection pump mount with the roller , to get rid of my t belt flutter.. gonna be 3 " exhaust down pipe all the way back..its already 3 " from the front of the bed back.....where did you order your 4b puck?..i have the 16v pressureplate in there now..it slipps...hehe....did you register for water fest for sunday? the dead line is the 9th???...cool i will talk to you later..

.53-.55 is way to big of a turbine AR for a TDI. You don't have to guess whether it will work or not, if you do some math on it you'll see you won't hit full boost until 3400-3500 rpm, which will give you less than 1000rpm powerband, and coupled with your short ratio gearbox(compared to a CTN 02A TDI tranny), will leave your car barely driveable.
Check out www.centralvwaudi.com , Simon made a 12sec MK2 TDI with a hybrid GT28R that was running a .49 exhaust AR.

That's all and good quoting what TDI-RS did, as you are new here I will let you know that TDI-RS was a frequent poster on the old host-board, and even on here some, we are all aware of what he did, and iirc it never broke out of the low 13's. Just because nobody has run this combination doesnt mean it won't work. :wink:
By the way guess what turbo TDI-RS's latest project use's.....
That's right a Holset HY-35, but with a custom split turbine section like the hx-35. :wink:
-
With a 16v head, 100cc more displacement and PD injection. Nothing at all like hilfolks engine. You can't argue with the math on this one, .53-.55 is simply too big. If you don't believe me, you can run the #'s yourself.
-
Thats kinda like saying a sledpuller 66 won't work on a cummins. The math doesn't work out on it either and yet there are alot of guys running them. Yes it does have some surging issues under certin circumstance's, but it has its purpose, making huge power with a single turbo. Same thing here just smaller scale. Math will only get you possiblities and numbers, somtimes you just have to build it.
I bet this turbo lights in the 2800-3000 rpm range, and will pull right through 5000rpm. In the process dropping hillfolker into the mid 13's, to start and with some work possibly crack 12's, but we will have to wait and see.
Oh and Andy2 has already proven this motor will spool the hy-35. :wink:
So then in your opinion what big single turbo does the math work for???
Oh iirc TDI-RS mentioned (back on the old board, when he was buliding the motor) that the T28-Hybrid that TDI-RS ran into the surge area as well, but was the best compermise of what he was looking for at the time. :wink:
-
In the case of the cummins, sometimes the headflow characteristics can scew the math. Honda's are another example of this, turbos that shouldn't work, work, because Honda heads are extremley well designed.
We're talking about a VW 1.9l TDI head, and its flow characteristics are nowhere near what a cummins or a Honda head is. The largest exhaust AR you want on this engine .49. Hilfolk'r, with the pump he has on the car right now, will make peak hp @4200rpm, after that he runs out of timing.Now he could mod his pump, to increase his timing advance, but then he runs into peak cylinder pressure issues, while he's trying to wind his motor out to 5000-5500rpm. VW counterflow heads have horrible flow characteristics, especially in the higher RPMs. Why do you think VW switched to a crossflow head on the MK3 ABA 2.0 gas motor???
You can put a hoslet on a TDI, and it will work, but at which RPM it works at is a totally different story. 2800-3000rpm is a long shot with a .53-.55 AR. People have already done the work for him on this engine(ie TDI-RS), and remember Simon had a built motor, Hilfolk'r does not.
-
i have 1 question,and this is all that matters to me
will this turbo get me in the 13s?
thats all that matters,i will sacrifice everything
hell,i will start throwing parts out of the car when i get halfway down the 1/4 if i need to :shock:
as it is now,it already starts spoolin at like 1800,and its on strong at 2000,by 2200 or so its flyin+its pooped by 4000,i dont bother with more revs ,maybe i go 4400 when beatin on it,although i still havent really turned down the maxrpm from when i had this pump on my 1.6im still learnin to read the guages,cause i get a little tunnel vision now
like DV thinks this is how ill hope itll be,as long as its startin to do somethin by25-2700 that would be nice ,and like 5000 max pretty much,thats not muchrevs over stock,4700 or so isnt it?
it only has a good power band right now,of barely 2000 rpms now,more like 1700 maybe around there...
besides its a 1.9 its got so much "na" grunt,it doesnt matter,when i blew that turbo and drove it home 60 miles,i had no problem still spinning the tires and even a little bit in 2nd also(the freakin exhaust wheel left the building,like elvis)
(http://img19.imageshack.us/img19/7751/hpim01959he.jpg)
lol i still ran like a 14.17 on that run...
(http://img102.imageshack.us/img102/1574/hpim01941xs.jpg)
i pulled the oil feed off the turbo and took a rubber fuel line hose off my wastegate then i found an old bolt layin in the dirt and shoved that in the hose+clamped it,then i clamped the hose to the oil feed+drove it home
i may need to do that again at waterfest if i get stupid,lol stupid freakin time bomb turbos
but right now,im just a little bummed out,cause i wanted to get this done before wfest,its too close,so im throwin in the towel,and will take my time,i dont wanna do a last minute rush..rabbittree do you hear me?lol
actually now i can take more time possibly,and do something about this crappy intake manifold too :roll:
http://westmotorsports.biz/
thats my "manifold dude"
want a custom manifold?he cut out some extra flanges
-
yeah blake i hear ya i am thinking the same thing on the it's close to the wire ...ha..although i already pre registered with the truck to race so now i gotta show hehe..plus i already took off the kkk and its down pipe and manifolds.. so i can't drive it now either so if i don't make in time i'll be rocking my passat or euro van ha, at the least i will have a good parking spot in the pits for the family hauler...clocking this turbo is a pain in the ass. oh well ...as for all this it won't work bs ..it may not be text book by any means but it will work..and im sure it will put a smile on your face..i plan to do some nitrous any how so im sure it can get it lit real early on the juice.... besides i wanted to do twins but andys problems with eth same setup i wanted to do discuraged me a little... and the intake issue ..man i was trying to a manifold to allow room for a gasser intake but it looks like i would have to really make custom exhaust manifold or cut and box out the fire wall to mount the turbo or turbos back farther..my deal is i want to be able to easily reach the nuts and bolts to remove the parts that i try to put on. other wise it will be a real nightmare to work on etc...

yea im registered for wfest ,tix are in my grubby paw,rabbittree,i wanted to call tonite to shoot the bull,sorry i got sidetracked,tryin to find a wierd woosh woosh sound comin from my belts,i think i got it
seems like i needed just a touch more timing belt tension,wierd though,it only did it for like 10 seconds on a cold start sitting overnite,i know it wasnt too tight,cause thats a whirr whirr sound,,lol me+my sounds :roll:

VW counterflow heads have horrible flow characteristics, especially in the higher RPMs. Why do you think VW switched to a crossflow head on the MK3 ABA 2.0 gas motor???
Hmm, so the racers that use ABA bottom ends promptly throw the heads in the garbage and put solid-lifter JH heads on instead have no idea what they are doing then? Counterflow heads flow quite well, especially after a little porting- sure, they dont scream into the 7000 rpm range as well as a Honda would, but most of the time people dont build them that way. TDI heads have the potential to flow a lot of air, if anything would be hurting airflow potential to spool up a turbo, it would be the stock TDI cam.
Not to be a jerk, just posting what I've read. Math works great for a starting point, but lots of people on here have done that already and realized that there is more to be had than what the math has calculated. Hillfolk, and others, are proof of that! :D

I may have a good combo for you hillfolk'r,In fact I will likely be running it myself very soon with the compounds.I will be putting the hy35 assembly into the hx30W turbine housing.The Turbine wheel OD's are the same and both housings also have the same nozzle area dimentions,The exducer bore will be the main up size.The hy's heatshield is bigger so the hx30's housing will need to be adapted to accomidate this without any issues :wink:.
So now we've droped the A/R way down by switching housings and still will flow well on the the top end without possibly opening the wastegate :wink:.
I agree that the hy35 won't work too well for your TDI,but possibly by making a hybrid out of another it should work well :lol:
Experts feel free to chime in about this making any sence.
-
Just try the hy straight up and if it does'nt work too well then try what I'm doing.
-
a tip for any one taking apart the hy35 from a dodge truck..its got a metal set pin for the the compresssor housing , ie ..to lock it in the right position for a dodge..ie you can't just let up on the snap ring and clock the housing..you have to take the snap ring out and then lift the compressor housing up ...remove the set pin and then you can play..what cm is this hx30 housing?..what does it cost?...the hy is 9cm..is the hx30 smaller?
thanks
deo
\x/ hillfolk!
-
The turbine housing on the hy is also located using another pin as well.I figure that the hx housing is somewhere around 6cm if I had to guess(.42-.47A/R)???I don't know.
-
Bling, bling... Now is the hx-30 housing divided or?
Does it require any machining?
This maybe the best cheap solution yet, instead of a custom housing.
Andy are you going to try this combo with your twins first or just as a single?

Actually you got it wrong most ABA(racer) guys swap the 9A 16V head, whichs make an ABF motor(available in Germany only). This will drop the compression down to about 9:1, are you gonna tell me the JH head flows more than a 9a 16V head???
As for the JH motors, most guys swap the ABA heads onto them so they can get an 8.5:1 compression ratio, ideal for a turbo gas motor.
-
Actually, VW switched to the crossflow head to improve crash protection.
People swap on counterflow heads because they want to keep their stock injection. The crossflow head flows a bit better but that's probably mostly due to the 7mm valve stems. All 1.8/2L 8v heads have a 30cc combustion chamber. The 16v heads all use a 45cc combustion chamber as does the 1.8T.
-
argh arguing about this or that cyl head.....hey andy do you have a part # for this hx30 housing ?..or any others available ..do you need a engine serial # for cummins to look it up?..seesm like every time i want a weird cummins part i have to find some sort of serial # for it to order the parts..i have dug around plenty of wood chippers, excavators, and boats to get serial engine #...
yeah teh exhaust house just wasn'ty coming undone quite as easy as the other holsets i've done.. that pin explains it i will have to try another method..thanks for the tip.

I will be trying this combo with my twins again and will be using the T3 this time around instead of the k24 :wink:.
Its not a divided housing,very similar to the hy housing just smaller A/R.It will require two machining procedures to accept the hy guts but not a whole lot of work.
HX30W turbine housing PN# is 353429907,It looks like that anyhow.I'll check tomarrow to make sure.
My dad and I will be adapting this housing very soon,I will keep you guys updated and post some pics as well.

lol,this is getting out of hand,now my manifold dude wants to install an ic too,"while we are doing this"
found a few on ebay,like a universal core deal,like 28 long 12 wide,and 3 thick(inches)
they were reasonable too like around 120 shipped!!
he's lookinat moving the rad a little so its mounted a little to the left,and a little angled like an a2 rad...
im trying to convince him lets get it running,then if it runs good,lets ic it
now this project is getting way outta hand
i may have to cut a hole in the inner fender for the airfilter
we may also have to cut up the neuspeed bar,the right rear part,and put more of an angle in one tube for more room
i said ill pitch the bar for now,but he likes em,i do too,so we will modify
i think he is sorta getting into it now,diggin it i mean
math math ,math blaaaahhh
what about my stock turbo? it shoundnt be "working" cause its like dead on the efficency thing,the math says,but the more ya dial the boost up,the more power it makes,even at hi 30's
yea rabbittree,i been playin with that turbo,basically sitting there is the carteridge,i cut off the wastegate bracket off the compressor snail,and beadblasted it so its purdy,lol
we got special compound action snapring pliers at work just for these turbos!!!
i saw that lil pin,after i figure out where the turbo will sit,ill drill so i can keep the pin
yea i agree with andy,if it doesnt "work" compound it!math and paper only get ya so far,then ya gotta go do it!!!!yea i can add 2+2,lol
-
The turbine housing on the hy is also located using another pin as well.I figure that the hx housing is somewhere around 6cm if I had to guess(.42-.47A/R)???I don't know.
Dude that is pretty small if you are right, I have been using .48 T3 turbines for a while, and with the custom cam and extra fueling I am seeing about 20 psi at 3200-3500rpm, the nice thing is that my exhaust backpressure is super low as well, about 1.2-5 to 1, depends on what turbine wheel I use too, I have had 1 to 1 ratio but spool up was pretty slow especially for just one turbo. I think for my next compound setup I am gonna use a .48 turbine for the highpressure turbine, and likely just a slightly modified hy35 for the low pressure, I've come up with a few new things to get those turbines spinning up pretty quick 8) Well I hope so anyways, the 14mm head will definately help :shock:
-
935racer your right the 6cm,hx30w housing is too small for an all out race machine. 6cm^2 converts into .38 AR at most.The 9cm^2 housing at .48 AR is the way to go for Hillfolk'r and my self.I'll retract what I said about the hx30/hy35 combo :oops:.
I think my spoolage problems were due to the k24's .3 AR and smaller wastegate hole.The T3's .36 AR and bigger wastegate will work better with the hy35+more fuel and your camsfaft too.
My old system with the k24 .3 AR and hx30 .38 AR worked well as they were sized about right,and now with the .3 and .48 it just doesn't work!!
I'll get this turbo business figured out sooner or later :lol:.
-
so my hy with the 9cm figures out to a .48 ar? i dont think thats too bad,whats the stock garrett i had,or even the kkk im runnin now?,aint they like .38 or somethin???
actually this thing has such a low end "hit" of power,that some low end power being sacrificed i may actually consider that a good thing,as long as it comes back in the middle or top end
that stock turbo exhaust port into the turbo is soooo small,i dont think you could drop a quarter in it(can.or us :wink: )
-
Sorry my mistake again,A2TD was right about the .54 AR on the 9cm hy.
Also I forgot to mention that There was a 6(cm) on the inside of the hx30 housing,and It really does look like a .38 AR when compared to the vw Garrett T3's .36 AR.
So the hy's AR still is a little big but may work good for us we'll just have to see.

As for the JH motors, most guys swap the ABA heads onto them so they can get an 8.5:1 compression ratio, ideal for a turbo gas motor.
Sorry guys, one more. :P Actually the JH engine already has an 8.5 to 1 compression ratio.
Anyway.........
You guys have got me all excited now.... I almost bought an HY30 on ebay just yesterday. I guess I need to get the damn engine first, huh? :P

Yes I know it's already 8.5:1, my point was people who want power out of a JH use the ABA head, as it flows way better than a JH head.
-
It all comes down to the headwork, the valves, cams, valve springs, manifolds etc, thats what is going to determine how quick the turbos spool up, because we have plenty of displacement, but unfortunately a limited rev range. I know everyone says headwork is the last place to put money for a performance turbo diesel, but its the first place I go on a serious build and its where the most time is invested, and it makes all the difference in making an EFFECIENT and clean buring, powerful, smoke free diesel.
-
i got one thing (wella couple)for you goys to think about,and pick apart
ihad this same injector pump on my old 1.6td jetta
you idi guys know the power band is like from 3000 to 5000 aprox,right?
now with this same pump,and the old idi td exhaust manifold+the garrett,or kkk td turbo,
its power is all from like 2000 to 4000
i believe this is just the inherent designs between idi+tdi
yea we could pick apart displacement+ manifolds+ stiuff
im really onthe sauce tonite,so this is just a thought
hey rabbittree ya gonna be home tomorrow(whoops today,remember,sauce)
ill give ya a call if so....
-
Yes I know it's already 8.5:1, my point was people who want power out of a JH use the ABA head, as it flows way better than a JH head.
Better, yes...as for how much better it is difficult to say. Most of the flow improvement in the ABA is from the 7mm valve stems (8mm in the counterlfow head). Those valve guides and valves can be swapped into the counterflow head anyways. Really, I think the benefits of the crossflow head are more in the packaging. A gas engine has a much larger intake manifold than a TD and it is quite difficult to get to to the turbo with the intake in the way and since heat rises the intake manifold gets to soak up the heat off of the turbo. I can post a picture of the engine in my Rabbit if you want....it's very difficult to work on at times.

well its on finished it welll not 100% finished butr enough to drive to waterfest and back..it runs good...it pulls VERY VERY hard in th etop of teh rpm range..you see no boost tunless you really want it...which on a tdi is ok as you have abutt load of naturally aspirated torqu any how..but the top is very nice i have no tach hooked up yet so itsprobably 3000 rpm before its lit but i swa 30 psi and it sounds liek a jet...ha..i am interested in taht 6cm mystery housing if am one has teh info or price and what machining is needed let me know..i disabled the wastegate and stillonly saw 30 psi max right now....blake has some pics .. it is drivasble and not to bad ..on teh highway it goes awesome 75 mph and man 95 100mph in a blink...no time

Figures when I am not looking for it I always find it and when I am I can't find it anywhere.
The two place's I would try off the top of my head are http://www.httturbo.com and
http://www.bullseyepower.com/
I know I have seen a pic of the housing on the net, but i can't locate it for the life of me. :roll:

Sounds like you need a custom cam to get that turbo spoolin sooner and one of the those 4 puck disks blake has 8)
-
Also I found this in my travels, it is listed as a compressor map for the HY-35 :)
(http://i23.photobucket.com/albums/b382/dvst8r/HolsetHY352003_vg30et.jpg)
Now it has somemarks over it and isn't real clear, but should give a basic idea, to those who like to crunch numbers. :wink:
I think the lines, are for a '84 - '89 Nissan 300zx turbo motor "vg30et"...
-
Now mabey some one wants to get really creative and clean off all of the VG30ET marks, and do a map for a 1.6TD and another for 1.9TD.
A2TD, you like to run the numbers right... :P :wink:
-
i een dont know how to read a turbomap :P :oops:
Greetz, Benjamin
-
Wow the efficiency on this turbo is horrible :shock:
This turbo is way too big to work on a TD/TDI. The map resembles that of a GT37, A 2.8 VR6 would have a hard time spooling this thing up. I think the ideal compressor set up for a 1.9TD/TDI would be off the GT28R, slap a smaller exhaust housing on, and you've got a turbo that can move a hell of alot of air, whilst mainting great deal of efficiency.
The GT37map http://www.atpturbo.com/root/maps/gt37.htm
-
what makes it so in efficient?.i don't know how to read a turbo map.. as long as it blows cool air 30 - 50 psi im cool with it...

Wow the efficiency on this turbo is horrible
Dont you mean fantastic? The 79% peak efficeincy island is small, but the 77% island is huge, far better than anything from garret. Size might be an issue though, as long as it doesn't make much boost before 6000rpm it should be OK... :D
-
well i don't know which of ya is being sarcastic but this turbo pulls the top end on a tdi m very well..if i can source a 6cm turbine housing it should be much better..as asingle turbo..as a big one for a set of twins i think it would work great....

\x/ hillfolk!

You could always do like what Andy was looking at, puting the Turbine hosing from the Hx-30 on to your Hy-35. It would be ruffly a 6cm housing.
-
Hey deo you figure out roughly what rpm you are making how much boost? Also you got any pics or 1/4 times yet? What pump are you running?
-
Hey anyone with some computer skills wanna lay a to4e50 compressor map over that hy35 one?
The to4e50

Pic stolen from vwmike
-
well i don't know which of ya is being sarcastic but this turbo pulls the top end on a tdi m very well..
No doubt, the thing that concerns me would be making 30 psi with it down low in the rev range. According to the map, the airflow through the compressor would be insufficient at low engine speed and you might experience compressor stall or "surge". The smaller turbine housing might spool it soon enough to allow that to happen. An electronic boost controller might be your friend, they can control boost levels as a function of rpm, might help you keep it together...

Plot the 1.9tdi on that map and you'll see how inefficient it is. I was referring to its implementation on a tdi, not to the turbo itself.
-
yeah i can take some pics and post em.. my pump is a cummins 4bt pump with a vw throttlke shaft and gov...i have the 260 kerma race nozzles...any how i have a tach but its not hooked right or adjusted right.. i totally disabled the waste gate so it acts like a buig turbine etc...fuel controls the boost.....i would say 3000 rpm or so to start maybe from the fellof it i mean its how you drive it if you have no load and drive easy through the gears you will see no boost even cruising 65 - 75 mph...if you guive it fuel it will spool in 2 secs or so at cruising speed its FAST as all heck on the highway when you spool it i mean 65 to 85 90 in a blink ..if you ever have driving a big truck pre accert it drives like that ie no boost till you wnat it and it sounds sick you can hear teh turbo whistleing before it sbuild boost and starts doing the jet engine noise its cool to hear th eturbo with no load and no boost just a little fuel and it makes a nice sound... i think if i keep it with the big single i will try to do a smaller turbine ..is the hy available with a smaller housing then the 9cm or do i have to mdify thta hx30 turbine to use on a hy and what has to be modded?.... or i will build aset of twins like a always wanted..and last idea was to use one of my m90 eatons for the low end..it would sound sick ..too not sure what to do..im doing my trans some with 367 r&p, quife, bolt kit, 80% cv cup springs, metal spherical ball linkage, and a wide ratio td trans, 4 puck and a beefy pressure plate...it should be nice them of course i have the water inj and a intercooler to do..also my cut pistons aand possible cam i want to try ...
i will grab some pics soon thanks
Deo
-
oh the 1/4 mile times sucked 15.8 through 16.02 with clucth smoke coming up through the floor .. blake was running 14.5...and he is lighter has better rings etc and water inj..i hope the other stuff i get going gets it in teh 13s ..heck blake ran a 14.02 or so almost a13 back in cleveland..later
Deo
-
also my cut pistons
why using shorter/other pistons?
heck blake his time, 14,02 is fast :D
Greetz, Benjamin
-
pistons are cut to allow higher valve lift and to reduce compression...
thanks

14.07 was with the old garrett
the best i got with this kkk is like a 14.2
i dialed it back (yes i lowered it) to 30 psi or so :shock: :shock: i didnt wanna nuke another turbo for waterfest,plus it was scorching hot,like 90 deg.f.
my best there was my first run in the mornin,a 14.47,but i had 2 or maybe 3 14.59's during the day,traction stunk,i was hookin up better on the drive home werent we deo???
hey can i grab a 3.67 from another tranny to put in my 7a box??
i can get one(s) from old boxes probably , from my "manifold guy" :twisted: :twisted:
oh yea, this is cause now im worried about the diff. rivits,and while im there ill do a 3.67 swap
deo i wonder how mine will run,ya know how we seem to "fuel" differently??
i guess ill find out
-
as fro the gear swap yes you can you just have to watch teh 9a or 367 ring and pinion shaft..it may be bigger i have to find mine and figure it out..as some part is bigger or one of teh bearings etc..check out that broke vw site ./.it explains soem differnaces.. phew up late working on teh kubota sucks im tired nite y'all
Deo
-
yea i went there,thas a cool site,yea seems like something about the pinion shaft is bigger and stuff
from that site if i remember right,it may make 4th gears an issue or something
-
um, at work the other day,i was playing around with a couple of 4b cummins engines
and i noticed the turbos had a very small exhaust housing
ill have to look again to see the tag on the turbo for the important info
but i wonder if one of these housings would work on my hy 35,hmmm
maybe i have to mod it like that hx 30 housing you guys are talking about
-
The turbo on the 4B is the HX-30 :wink:
-
If its the Hx30w (wastegated) model then it can be adapted to work on the hy35.If its a non wastegated hx30 it cannot be adapted.Remember the 6cm/.38 housing is a heck of alot smaller than the hy's 9cm/.54.Somthing like .46-.48 would be really nice to have.
My dad and I have been doing some reworking on the hy's turbine housing to drop the AR to aproximately .48 ,It spools alot better now :D.
I had 2 hy's and both turbine wheels measured different in size :?.So it turns out that the one turbine wheel was smaller where it exits through the exducer bore.The turbo was in ok shape no play or anything and the wheel almost looked like it had been made smaller from the factory,no wear on the fins or sharp edges.It did have a weird ridge in the wheel where the curve of the wheel changes,this is where the wheel changed in size for whatever reason.
Anyways this gave a bigger parallel clearance between the wheel and exducer bore all the way through.All we did was machine up a sleve to bring the wheel to housing clearance back down to spec.
So by making the exducer bore smaller we have effectively lowered the AR to somthing like .48.
The wheel size difference on the smaller Dia was somthing like .070 thou :shock: huge, while the bigger dia of the wheel remained the same within .003 thou :? We have no idea how this happened but we'll take it 8).
-
yea,it had a wastegate on it,i remember that much
ill do a closer examination tomorrow
you modded your housing to work,but can i just "slap it on" ifi get one of these housings???
-
Nope, you'll still have to machine 2 parts of the housing for the hy's wheel and heatshield to fit.
-
cool,im tryin to see if i can get a used one thru work..... :wink:
-
one of the ones that guy brought in lastr week was shot,wheel was all sloppy
so im gettin that (iguess its an xh 30w)exhaust housing w/'gate assy
for nothin,the boss's kid said i could have it!
sweet
:wink:
wacked out holset setup,here we come
i hope if goes like a bastid :twisted: :twisted:
-
nice score! :D
-
any pics andy of your housing modifications to reduce the ar?
thanks,
Deo
-
I knew I should have took a pic :).Next time its apart I'll definitely take one of the housing and wheel.
-
well a pic showing what to machine and how much etc ... etc.. I want to know what to tell my machine show to do to my hy 35 housing.. or heck .. if you want the $ I'll send it to you ... for you to modify for me.. let me know I am dead serious too.
Thanks
Deo
-
The only problem with the mod I've done to my housing is that the wheel has to be smaller.As mentioned I have no clue to how the wheel on one of the hy's I had was smaller?
If you could get the wheel downsized like mine then you can make a sleve for the smaller wheel to lower the AR.
It was pretty simple to calculate as the hx30's wheel(.38AR) was a certian OD and the hys wheel(.54Ar) was another cretian OD.So to get the .48 AR we luckley had a worn down wheel?? that just happened to be in the correct size to make a .48 out of it.
Remember both wheels and housings hx/hy had the same nozzle opening dimentions so the housings outlet(exducer) DIA is what makes the AR bigger or smaller.The turbine inlet is simply sized for the needed flow of the turbine outlet.
I think this makes some sense :D.
-
i got the freebie housing tonight
then i stopped over at manifold dudes place where my hy is
he wasnt there
i wanted to see what needs machined on the housing
oh well,maybe tonight ill just try to clean it up some in the garagwe+ snap some pics
iknow this turbo was blowed up
its exhaust wheel was contacting the housing some
lol maybe i wont have to machine as much,and the wheel did it for me :lol:
-
i brought the housing to manifold dude
he will draw it up on cad what we need to machine,but he wants to machine more than 1,for cost purposes
anyone else got a hx30w housing they want modded to fit a hy35 turbo ??
how bout you rabbittree??
anyone???
-
its an interesting thought and I've been trying to get a used holset for close to 8 months now off of EBAY that I could rebuild, etc. but still haven't come across a "good" price for an unseen "needs rebuilt" unit.
Ever since the mTDI project started I've been looking with no luck :( Any ideas? What kind of cost are you looking at?
Joe
-
i dont know ore its some usable information,
but someone with a 1.3 GASSER just made 355hp@2,2bar(32psi) with a Holset HY35W from a 7.0diesel truck
it makes boost on 3000rpm, between 6000-9000 he got good power.
Greetz, Benjamin
-
joe go on a dodge website like the turbodiesel register i know there is a hy35 for sale for $300.. most are about that proice tahts what balke and I both paid fro ours.. and they don't need aa rebuild as most are low mile takeoffs when th owners put a bigger turbo on there truck... blake price one out at your job for me i may be about to swing it if its cheap enough...let em know i will look around today at at truck yard for one..later
Deo
-
Deo, I'll look there and I'd appreciate that :) Let me know...
Joe
-
w eeyeballed the machining needed,basicaly we would measure the stock hyhousing,and match the measurements to the hx housing,i didnt measure the exh wheel
-
I did happen to win another Holset tonight to play with. Its an H1e, similar to the H1c one of you guys had got. 18cm. Commonly showed up on the 4bt motors as well. 50.00 for it... sounds like it needs a new compressor wheel...
Now to find the compressor maps for these beasts...
Wanna sell me the compressor wheel from the parts H1c ?

call my job,and ask for "brian in the pump room"

just have all those numbers off the data tag ready for him..... :wink:
-
will do...will have to wait until it gets here but that'll work. From what I remember the H1c /e's etc. were good units...efficiently working up around 30psi or so.
That mean your guys can order parts or what ? That could end up pricey :) I'll do that though once it arrives...
Joe

That turbo is from an older cummins 6CTA 8.3L to be exact.

lol....yum....

yea we are a cummins b/c dealer,,and a dealer for alotta stuff,,,holset turbos too........i think we are lame and dont even have a website though(thumbdown)
-
yeah joe i think that a little big for a vw ..my 6 bt had a h1 c on it and its similar 18cm housing on teh back..not sure if thats a start for a vw turbo or not but its not mapwidth enhanced either..
i would look at a hx or hy....just my humble opinion.
Deo
-
yeah, just really picked it up for the price or possibly for a friends gasser motor he has been working on and plans to turbo this next year here. If I can use it..I will, but my intentions were more for the price of it. I plan to find an Hx or an HY... just haven't found one that fits the bill quite yet.
Joe
-
Joe I have seen a couple hy35's go for under 100USD on ebay in the last few months, just keep looking they are there. And that h1c is not such a hot unit, the hx series turbos are much better, and its too big for your tdi anyways.
Speaking of which any updates on your mech tdi?
-
like i said, more got this because of the deal on it and its for a friend should he go that way. for 50.00, can't beat it.
I'll keep looking for an HY/HX unit....
As for the mech. TDI, its well up and running, doing break in miles now, no more than 6lbs at the moment. I need to invest in larger nozzles as I'm only running sprint 764's on the 12mm pump and I really can't get it to smoke like I'd like it to in order to find the best tuning curve. Of course, that will change once I can raise boost, etc. too. Just feels underfueled at the moment. I may be making a few other pump adjustments as well. Currently its setup with the VW gov. and LDA but still retains the stock timing springs and KSB device which I intend on changing out and disabling/removing the KSB...
All in good time... this weekend, reindex'in the throttle shaft a bit and relocating the battery so I can plumb the air water intercooler in.
Find me a deal on a holset :) I seem to find the 200+ ones...
Joe
-
I will keep a eye open for ya.. I may be interested in the h1 c or h1 e you have for my dodge I'm putting it back togther and ui broke my center section from teh stock h1c trying to remove the turbine housing dumb but oh well .. so if you wanna sell you holset let me know thanks deo
-
i'd be willing to sell it for whoever wants it first. It honestly is about the lowest miles unit I've seen, supposedly has no shaft play and just needs that compressor wheel. So if you have one with a good one, it could just be swapped. We could work something out if you find something for me too! Either way, it'll be here :)
Joe
-
a bit off topic and I promise from here it'll be back on. But...my dad is up this weekend and I finally have two sets of hands to really help me tune things.... we reindexed the throttle shaft tonight, backing off the idle stop first all the way so I could use more of the max fuel screw.... then the throttle shaft, slowly bringing the idle up while backing off the throttle until I had it perfect and BOOM!!!! Holy #*%), this thing is INSANE.... I've finally found my smoke and blew a boost tube with little effort. The smoke is "unseen" unless I lay on it but there is more room to tune even from here....
WOW... looks like we'll be having a Holset gruppe here....this winter though :) For now, the T3 :) Interested in seeing how the .48 hot side does once the car is completely broken in and intercooler plumbed with boost at close to 30psi. Thats about 800 miles yet though :( Tomorrow...oil change for first time, Amsoil going in and me bungee strapping my foot back to stay out of it for now...
Anyways...back to topic
Joe
-
dont be afraid to romp on it a little,put your foot in it
the rings are seated by now,so all you are waiting for is the bearings ,and theyare pretty much there
of course wait till its warmed up
i waited a whole 2 or 3 hours before gettin on it
i was still shifting before 3000 and hauling like no idi ive ever seen
id wait till 3-4 k to run on the amsoil
i waited till 3k till i switched to synth
just dump it again at 1000,and at 3k if its feeling good+loosened up some switch over.....
lol i was nuts,but nuts is cheap insurance to me
a 25 dollar oil change compared to a 5000 dollar engine???no argument there
i changed the oil after 30 mins of run time,then at 150-200 miles,then again at1000 :roll:
anyone still wanna get a hx 30w housing bored out??manifold dude is bugging me to get one......
-
I'd be interested, but don't have one in hand at the moment...
On the syn. part... here is the deal. I started it on rotella, ok....good, cheap, etc. 15w-40 though and came across a good deal on 15w 40 Amsoil that I figured I'd use as part of a the break in....a STEAL of a deal so I just bought it to have. I eventually need to switch over to the 5w-30 I'm assuming but I don't know as if I saw the harm in putting the amsoil in before the initial break in period was up...
Is it a "cost" thing with using the syn in the break in or a mechanical thing that you've experienced? Just interested in knowing...
Joe
-
How many miles on it, Joe? I think it's been discussed to death, but from what I can remember on TDI club, after the rings have seated and the oil has been changed the first time, it's time to pull the trigger. ;D
Man I wish you lived closer so I could see that thing. I like your setup so much that I am planning on using a lot of your ideas for my build, if you dont mind that is. ;) What's that saying, "imatation is the best form of flattery" or something like that?

Brendan,
Eh, roughly about 100miles I imagine. I did a few test here and there, ran it through the low ranges, let it warm up and checked the racewares, etc. Then ran it back and forth with the pump turned way down here for a few days to work...about a 40 mile round trip.... so, first oil change today and then go from there...
Need to relocate the battery as I said, tomorrow it looks like as its raining today, also made new 4gauge cables for the alternator and grounding points to clean things up a bit and would like to find a bit more rubber and a couple bushings to dampen the noise the the H blue fuel pump I've got on the car....fun stuff.
Nope, you know...i don't mind at all...afterall that is what these forums are about. An exchange of knowledge where we are all participating. The only time I don't like it is where you share info and ask questions to people regarding some of their findings that they don't share or you find out they are profitting from your findings and/or ideas. That stinks...
I look forward to seeing your project as well and perhaps sometime when I'm home (around the Erie, PA area) We could meet up, etc. I may go to H20 show this year possibly as well as MAYBE TDIFest...but, we'll see... not alot of love for mechanicals on that side of things but then I could always turn ends and change opinions.
Joe

yea use dino oil for breakin
if your rings didnt seat in the first 5 mins of running,they will never seat
i really liked the dry film lube for the bores from total seal
upon startup, (i prelubed) i fired it up,got oilpressure for 10-15 seconds,then i raised revs to 2000 i held the revs at 2000,and blipped the throttle hard like every 10 seconds,gotta load the rings to seat them correctly
i shut it off after 15 mins or so,,looked around,before a road test
yea wait a few thou before switching over to synth
yea its not a cost thing,its a mechanical thing
dont be too gentle on it i had one last week that the guy was too easy on it and he had allkinds of problems
you got 800 miles on it
get on it,its ok to let it rev to 4000
heck when i was blippin it during break in i was hittin 3500 probaly
you arent doing any damage,and ya gotta be what most people would think is "bad" for an engine on a break in,like holding hirevs,and loading it some
lemme post these old pics from w'fest 03 here too for ya that i found somewhere online :wink:

Joe, whereabouts are you from near Erie, PA? I lived in Erie for about 9 months, 225 West 8th Street, near State and... Liberty? -- been a couple of years... :oops: Very near to the Gannon campus. I used to always drive down State toward the harbour and then onto Bayfront Pkwy on my way to work at GETS. I was a Resident Design Engineer for my consulting firm in the GE Tier-2 locomotive Diesel program (https://www.getransportation.com/general/locomotives/technology.asp), known to the public as "GEVO."
(http://www.tdimeister.com/pics/misc/on_any_given_friday.jpg)
I met up a few dubbers there and had a memorable race with one guy in a modded GTI (with me in my Passat TDI) on a deserted stretch of I-79N heading back to Erie from a old-timer car show in Meadville if memory serves. I had my car's spedometer pegged at 220 km/h (137 MPH) with my GTI buddy far behind. To add insult to injury, I also beat him in a friendly traffic light drag race shortly after that incident. :D
-
I'll def keep the dino oil in there for now...maybe will go pick up some more Rotella I guess until the next changeover.
Def. haven't been baby'in it, but to a certain extent, probably...staying off of it. Now it will be hard to with as much power as I have found with the reindexing of the throttle shaft and lever. It was interesting how much the power came up and how far out the max fuel screw was initially when I had it on the road last week running around...and how "under fueled" it felt. I realize that I'm not going to get PP nozzle (764's) or R520 performance out of the Sprint 764's I'm running right now but the power is alot better and I am seeing some black smoke on the initial adjustments now. It'll be wise for me to get the intercooler plumbed in quickly as well as the fuel cooler setup I'm going to install...maybe this weekend but right now the weather isn't looking to promising...
Oh...on the PA connection note... my hometown and parents home is in Warren, PA... about 45min or so east of Erie. I can take note to some of those places you mentioned as I've been around those areas and such. But Warren is where I've spent most of my time up until when I moved to the buffalo area right after college and then 8 months later to out here in South Central NYS

i did the start up on the gen for a pump station there in warren,pa
it was snowin like crazy too,driving up route 62? to get there from rt 80,there were these huge pine trees along the road,and they had huge chunks of snow falling off them hitting the service van,it was like huge white "boulders" of puffy snow landing on the van :shock: i didnt wet myself,but ill never forget that ride :wink:
-
I think I know exactly where you are talking about coming up RT62 from 80. Some of that is through the national forest and it is "right there" . I can vouch for some of those experiences :)
Joe

how comes everyone is afraid to break in there engine on synthetic, or is it just one of those things where no one knows if it will be bad or not, and they don't wanna try it cause if it is bad then you just wasted a motor build for nothing, so everyone just goes dino for safety?
-
google answered me, and google says synthetic is fine for break in, but i'd rather have piece of mind...
-
Actually...in doing some digging on break in with synthetic vs. conventional... Audi actually starts there motors supposedly and suggests initial break in with dino oil. The "idea" I've gotten from reading about them as well as a few other places and digging in the archives of TDIClub is that dino is better to break in the motor because of the reduced interval it actually takes to break the motor in with dino vs. synthetic?
In re-reading that it makes no sense...or sounds jumbly... but initial break in because of synthetics "more slippery" consistency vs. conventional oil you could be breaking in a motor with synthetic for ALOT longer. Supposedly in reading through on TDI club about some new ring installs, etc there are tests out there that show that rings seat and break in better along with other vital components with dino than they do with synthetic... they break in either way yes, but from the readings those broke in with dino oil broke in faster than those with synthetics from the get go.
Either way...I changed the oil today in the car... with dino.... again at 1 thousand and we'll see... That amsoil is sitting there and tempting to be in the car and since its 15w-40 I'd rather use it sooner than later (unless someone is interested in buying it...) as I'll probably eventually switch to the 5w-30 it seems that everyone is running. I honestly didn't even check into it when I was building the motor to see that everyone was really running 5w-30 vs. 15w-40 anymore. I always used to run it...oh well. :)
If someone is interested in the info, i can post...

nah that makes sense to me. the rings need friction in order to seat. i've also read about driving a car in controlled intervals, and doing say first a wot run to 3k, then a wot run to 4k, and then a wot run to 5k , just examples, but that's supposed to help seat the rings very well. and that babying it ain't always good, but obviously to an extent it is.

only place I'm really babying is boost wise...staying around 10psi or so... not going to take it to 20 until I feel comfortable with it broken in...

20 is nothing,the boost wont killya,,boost it allday,its the feuling,keep it turned down onthe pump,but dont worry,letit go 20-25,,,what do you plan on letting it go to with that turbo??you know me,i like to ride with an almost closed wastegate 30+psi ,dont worry about 20,itll be fine

I'll probably take 25-30 with it once I feel comfortable with it. I need the R520's because right now I believe its really underfueled the way I have it set up. Running Sprint 764's til I have the cash or rather BIG money for the R520's
