so you almost "GOT BOOST" congrats, looks pretty mean. 8)
-
hmmm...looks like the biggest restriction is going to be.....the engine.
That is scary...I like it.
-
Looks purdy :) I look forward to hearing/seeing results from this engine.
It looks like you've converted to serpetine belt too; I wish I had done that earlier. Have you addressed the crank key issue?
-
Beautiful! It's art. It's amazing the kinds of things that can be fun to look at. What are the details or specs?
-

Yeah. Is that a 1.6L? :oops:

No serpentine there, thats just the intermediate shaft pulley, the timing belt runs on that.
As for the turbo looks like some sort of t3/t4. And that turbine looks huge, like .63 and up kinda teritory, even with retarded amounts of fuel I doubt you will make over 10-15 psi with that set up and likely not until way late in the rev range, like 4-5k.
-
a good sniff o' nitrous will wake that badboy up easily.
-
I was thinkin more water and maybe propane, but yeah definately something other than diesel!, or maybe a smaller turbo is supposed to go under there.
-
its a 52 trim compressor side and by measuring the exhaust wheel its only 1 mm larger than the factory kkk so i dont thin it will be to bad. I am thinking retarted amounts of fuel to lol i already have a nitrous kit to spool it down low. we should se some results in a couple monthe because i have to break everything in. The engine is all 1.6. As far as specs its bored slightly and head is extremely ported and polished and i fiddled around with the intake a bit. For the boost pressure it should go way over 15 psi no problems. Remeber boost pressure is a result of restriction.

For some odd reason at 2:00am I thought you were using serpetine belts.. note to self: Don't post when sleepy.
When do you plan on completing the engine and installing it in your car? :)
-
hopefull next weekend it will being going on its first journey as a td. :lol: CAN'T WAIT!

I have a rather very important announcement to make...

Beautiful, man, but u could start u'r own thead.
What turbo is that?
-

I'm betting on a snort more than a sniff...... and ANOTHER 2000cc's displacement outta spool that blower up!

That's actually Smokeydub's engine....taken with my crappy camera phone... :roll:
I just hosted the pictures for him...

spool time is no worries the turbine side is a .48 A/r and on the compressor side its a 52 trim. The turbo is a GM8 off of a 6.5l chevy turbo diesel

The turbo looks great.......From my own experience, I previously owned a Callaway turbodiesel and that had a big Rotomaster TO4. The turbo looked very impressive...but in real world it only made 10-12 psi boost with the fuel screw turned way up...serious smoke off boost. The ports were opened up enough that we went thru the gas carb intake match porting it to the head. The engine didn't really make any boost until 2500rpm..after that it was great. It was great on the highway but around town it had alot of lag, By todays standards, I would consider it a dog.
You may want to consider a tdi intake manifold, such as an AAZ or 1Z are nice and no egr valve in the intake tract. This will allow you to port the head even more and you might want to look at a GT turbo...with better, faster spooling wheels. If you're on a buget some Saab 9000 aero's come with a really nice GT/T25 turbo good for 200hp+ on a gas, and it's smaller.
I think 935racer is right without a big pump 10-12mm and/or propane to get the turbo rolling I think you may be dissappointed with the all around performance, but please don't be discouraged. If max hp is what you're after a big turbo is the way to go.
-
k24's on 1.6L engines don't really make much boost until over 2500.
-
so i can start boosting at 3000 and flow 3 times more :D
-
I have used a .48 turbine on a 1.9 and a 1.6, They were both pretty laggy, definately coudl have used a big badass pump, but they still smoked alot until they spooled up. This is why compounds is so desirable quick spool off the line all the way through the rev range. I would definately put a custom cam in there to get that thing spooling sooner. If I remember correctly we were making about 30-35psi of boost on dvst8r's 1.6td with a k24 at about 4 grand mayeb a bit less rpm than that even he may remember better than me. But yeah that thing is gonna smoke like hell to get it to spool, but hey smoke is cool 8)
-
not go to go off topic here, but is that why when i stomp on the pedal at say 2000rpm and a decent amount of smoke billows out the rear until it gets in between 3000-4000, is because of the turbo needing to spool up first?

yep... I'd recommend getting an EGT gauge to make sure you arent cooking any internal parts while spooling up your turbo. I'd recommend not flooring it until you reach 3000-4000 rpm, unless you have the EGT gauge hooked up and running.

In upper gears 3,4,5 by 2500 - 2750rpm 30psi-35psi, with a stock pump maxed out. I think with a big 12mm pump and some nitrous for when you have a point to prove you will be golden. If you have the budget I would definatly look into a gt series turbo, (esspetially the ball bearing ones) if you want to rock somthing that big, they just spool up so much quicker then anything else.
Hey rock it and report to us, if it doesnt spool up quick enough there are always options. Oh and that turbo should be good for about 240-265hp on a diesel. :wink: Which means you will need at least a tweeked 12mm pump to take full advantage of it. :twisted:
-
One more thing. You might as well manually block the wastegate closed, as you will Never overspin that turbo, with a 1.6 or 1.9L motor. Also even if you only make 15-20psi with that turbo you will be moving more air then a k24 or t03 at like 35-40psi. :wink:
-
the reason why im running this turbo is because it was free and in excellent shape. Does anyone have any hp and tq predictions with a 12mm pump tweaked? and what can i do to keep low egts? I am running a beefed up saab 95 intercooler.and might use a nitrous purge to purge it on to my intercooler.
-
If you can keep it together... 12mm have the fuel capacity for 250+hp so... I guess we will see. 8)

Don't forget water-methanol injection to lower EGTs as well. Not promoting the company I work for as much as trying to improve awareness in general - I had no idea it could drop EGTs by 200-250 degF before I started working for a water-meth kit mfr.
It is popular with the bigger truck guys because it allows them to use higher stages of their programmers and not have to back out of it (or back out as much) with loads on grades, etc.
Any special intercoolers needed for holding together at the higher boost pressures?
-
well the intercooler is a big but plastic tanked intercooler. So i had to reinforce the tanks. Again the reason why i used it because it was free. I used an epoxy called panel bond and i ran a nice bead around the tank fingers so the dont spread an blow the tanks off.
-
I almost had to wear welding glasses to see the engine close up :P
The engine is rockin, can't wait to see it's 1/4 times
All hell will break loose if we both run up against each other :D

you will be sitting there smoking and ill be at the end of the track :D

Well Jeff how does your beast work,Fill us in?Are you going the the dyno/GTG?
-
stock pump running 17 psi seems not bad spool up is decent. I have an egt hole drilled and tapped so there is alot of leakage. On friday i get my pump and injectors so ill let you know then.
-
Cool,I may have mine running tomarrow night. I'm in a mad rush to try make the GTG with it.
-
which gtg? the dyno one?
-

Yep the GTG/Dyno June 3.
