hi there,
im trying to setup my autometer tach, and cannot use the idle as a basline as this is not standard.
i need to know what the engine will rev out to to set the redline. i have not done the governer mod.
is the figure 4500 or 4800? or something else.
any help would be greatly appreciated... esp from those with GTD's with o.e tachos :D
-
hi,
this is great info. ill seek out a shop with the tools - but for now if i could know the approx redline that would be great
im in the uk btw :D
this is the car in question :D

So you´re at dyno, what´s the results :D
-
Huge lips. I love it
-
the best way to set your tach accurately is make sure your speedometer is accurate using one the radar trailer things the cops let sit along the road, then once u know ur speedo is close to what it should be find the gearing of your transmission and figure out what speed your engine will be at at 60 mph in 5th gear, or w/e and check a couple different speeds in different gears and what not.

Hi Mate, the red line on my tacho is about 4750. GTD that is.
Just sent u over here from e38, and then read this so u have already found it, ah well. :roll:
Was that your caddy that was on stage at e38? These guys need a pic of that beauty :oops:
-
^ yes, yes we do.
And that is one hot GTD!! 8)
-
haha thanks guys!
not my caddy - a good mate of mines tho, AAZ with T3, pump mods and 2.5" exhaust with no mufflers - just a pipe, runs 28psi of boost :lol:
mines a GTD with a T2 and downpipe back 2.25 system (still got the ***ty o.e dp) running 20psi and some pump mods to suit... oh and an AAZ gasket.
only hit 88bhp and 158ft/lb on the dyno. we couldnt get the transmisson loss calculated properly cause we didnt know the RPM at 60!
it should be over 100bhp really i would have thought.
i fractured an injector rail last night so im going for a T3 with a custom 2.25" downpipe going straight to the floor... no side exit were talkin under the car exit :D
with some head studs and more tuning.
another question - you rekon its worth my while to go to AAZ injectors?
how much boost do you think my setup will take safely and what power should i hit?
thanks guys :D
ill get you some pics of the caddy from hell :wink:

p.s does anyone know what EGT i should be hitting with a T3 and free flowing downpipe?

Hey mate, your GTD looks brilliant, any chance of some more pictures?!

These will fit in the 1.6 bodies as well.
This has a lot of info on this subject

---------------------
this can really depend in fuel settings, over fueling can help lower egt, less fuel can really heat things up again.
i'm running a Sb 1.6 td, kkk14 20psi boost aaz metal gasket, ext oil cooler my egt temp really differ when i play with fuel delivery side of things. i tink im around 100 horses too.
nice cars there BTW, im also a uk'r, pleased to meet you. what area you in?
ps mines T3 caravelle :wink:
where was the last photo taken? which show?
-
pretty sure EGT increases with more fuel. More smoke = higher EGT. Less fuel means the burn will be completed fully and there will be no smoke and much lower EGT

To find rpm @60; jack up front wheel stick in 5th an rotate for 1 rev of engine find out circumference of wheel find out revs per mile...

hi guys, thanks for the replys!
im from southampton, not too far from london!!! the pics from the ed38 show 1st sept in northampton :D
little more progress....
defo liking what i read on that nozzle link - thanks for that 8)

sounds like a gasser turbo... with diesels more fuel = more BTU's, less fuel = less BTU's. gotta luv diesels!!!!!! no wasted fuel like guzzling gassers
EGT's should be a heck of a lot lower than with the stock restrictive DP. 2.5" or 2.25" ? an intercooler will also lower EGT's by a hundred degrees or more depending on its size if you run above 15 psi boost.
-
RPM and road speed are directly linked so if you find out what tranny you have you can find out the gear and final drive ratio and calculate the RPM based on what speed you are going. Stock tires are 185/60/14 I think so if you are running something different you need to take that into account (smaller or bigger tire diameter will throw off the speedo). There are a few websites where you can calculate the % the speedo will be off with different tire sizes but I'm lazy so I'll leave the searching up to you.
I recommend you setup your stuff using lower speed (like 30kph) as mechanical speedometers have a tendency to be inaccurate at high speed.
-
Hey Stanton, Whats that turbo off? Looks flippin massive against what I presume is the stock GTD turbo?
-
That is one sweet looking car :wink:
-
Ugliest GTD ever, wouldn't give you £100 for it mate :P

Thats not the ugliest GTD ever, that accolade would be better bestowed to my abortion of a GTD :oops:

D you mofo!!!!
she runs, just need to get the exhaust finally welded (2.5" all the way thru and exits out the side) and roll 8)
ill get you some vids :P

bert thats real tidy man. like tht lots :D
ye thats the std T2 against the T3... just a little bigger....
oh and heres the 2.5" downpipe mated to the 2.5" system.... no boxes

How did you sort out hangers for that side exit system? Is it really loud? Looks and sounds great :wink:
-
its just universal hangers bolted to the body :D
its real loud tho.....u can hear the turbo spinning at idle 8)
-
I have a nice chrome sports box on mine but i think I'm ready to ditch it for a straight pipe! how did you get G60 arches without the little piece that lines up with the rubbing strip on the door?
-
just cut it off dude :D
it has front g60 arches on the rear too....
-
Hi bud
Remember me? I was making wide steelies and stuck a post on E38 forum.
Anyway I never knew you were a soot head, my cad's got a GTD, 2.5" downpipe, single silencer system, big FMIC behind grille.
You originally asked about tachos - I can take a stock VW petrol tacho and convert it to run from the diesel alternator if that's of any interest to you?
-
hi! ye 100% a soot convert :D
got me an autometer tach kit in the end geez, i was the guide on the w terminal... couldnt be bothered tbh :P
you got any figures out the caddy? and pixxx!! :wink:
-
No figures - stock boost and fuel. Engine's a bit tired to start throwing boost at it, I need my caddy daily.
£50 from local pig farmer

Under bonnet - not show tidy but then it's a £50 caddy built on a budget to be used and neglected

cool as *** geez :D
like the green touches :D
just to get this straight, more fuel = higher EGT... so smoke = a hot run?
if i up the boost and have slighlty less smoke this will also reduce egt?
how do you best think i shud set the car up with 23psi of boost?

if the engine is tired, more boost = more blowby... gotta watch the oil consumption.

kool ill keep an eye on that, whats the oil capacity of a GTD btw?
oh and my cars got a neat new trick!

Ok after seeing that video you've convinced me, straight through system.... 8)
One thing though, there's lots of guys around the town in your typical done up civics with jap cans on the back that are really lairy and annoying, does this happen if you put a straight through system on a TD golf?
-
Oh, I don't know why, but that last video has struck me as so flippin' awesome! I can't stop grinning at it! :lol:

its a totally different noise with a straight pipe. the turbocharger acts as a muffling device, so its really not as bad as a straight pipe on a normally aspirated engine. those fart cans resonate so much... so annoying sometimes.

They get loud when you wind 'em up...

I ran mine for a while with just the 2.5 downpipe and it genuinely isn't excessively noisy.
The turbo kills a lot of noise because it breaks the pulses up into tiny little chunks.
I've got a single box on the system now and it's quiet, not stock quiet but quiet enough.
