would you be able to map it for me ?
TT38 on 750cc's?
or is this not something you do? i.e map an engine that isnt built by
yourself?

If you have a weber then person I would go to is Stu as he maps them size injectors or ask Ahmed to map on these.Mark

Turbo's
I have a TT T38 on my 3dr. Its got a .76 A/R compressor with a .63 A/R turbine. I had the engine biult and dyno'd by Harvey with which i supplied the turbo. He had trouble making good horse power out of the turbo as the waste gate wasn't up to the job. Sent the turbo off to be modified, then it made 432BHP on the dyno.
Ive had T34s with both 48 & 63 turbine housings, and the T38 compared to the T34s is not worth the extra money. I paid £900 for the turbo, £100 for the waste gate modifications and £700 to have it live mapped. I wish i had thrown my money at a T4.
I would rate the T38 as having the same amount of lag as the T34 with the 63 turbine housing. When the power comes in, it comes in much harder and is still making BHP at 7,000 revs. But you would need some serious head work, cams and lowered compression ratio to run this turbo.
If you wanted it to be responsive with good power, 380BHP, i'd go with a T34 with a 48 turbine housing, which you can get a cheap off the shelf eprom for. If you wanted big power go down the T4, GT30 or GT35 route.
The T38 is the one in the middle of these.
It drives nice around town and holds good power all the way through to 7,000 revs.
The power graphs are old but you can still make out the power run.

405 (*cough bollox cough*) bhp
Wouldnt make 370 on the rollers, be lucky to make 360.
Dyno graphs are too perfect ACT @ 20degree's cause that always happens on full boost, in realiatly they are total shite. should be mapped at a temp that is more liek real life to get accurate readings.
Mapped on dyno - melted twice due to the map. don't be a sheep and take it somewhere that knows what there doing.
Putting my engine on the dyno was the worse waste of money i have ever done.
I have no idea how the lambda works on this graph cause that aint the map i got for my car, no chance.

Sorry bill - after you have taken your tongue from the ass of scs, i was told that was inlet temp by SCS.
If its not then, i am no more shocked than normal.
What is funny though then at 40 degrees as you say.
Why on my map that i paid to be dyno'd is there no fuel at 6500, the fuel goes down in the graph not up as the dyno plot states, but this is stated in the graph @ the next point 12.4 as its starts to run learn at the top end....awesome....MELT - and it did......TWICE....
2 engines laters
As said, its totally pointless.

According to those graphs you make 200ish hp @ 3100
So standard car is 200hp at 6000rpm with 10 psi odds of boost,
So how are these engines making 200 hp at half the revs, no boost and lower compression ratio - some with head work and wilder cams...
Errrrr - Superflow Dynos suck lol - thats just an opinion lol

Stu, as normal you try and belittle me, not that i give a shit cause i know you better than you think.
SCS said thats the Charge air temp to me, up until now i have never known or thought any difference. Cause i didn't care, so if its air in the dyno so be it, i didn't know - i only know what i was told.
So i am guessing SCS are talking bollox, no surprise.
So stu do me a favour.....

Yeah, when your wrong its always someone elses fault, you cant JUST be wrong can you, it always has to be a fooking conspiracy theory
Inlet temps = Inlet to air filter.
Charge temps = Air after injector.
You initially said INLET and then changed your story to CHARGE.. but hey, thats my fooking fault too yeah?
(note the colour coding to help you with temperature relation.. )
Oh Look......

Stu, as your being a quoting picky bastard as normal.
I meant inlet, as in charge inlet, the only temp that matters lol.
Shall i quote you....
This is where and when i stopped ever listening to you mate, lieing to sometone to there face is most embaressing.
PLease delete my account you absolute c.u.n.t

I wished you season's greetings after your absence and I get abuse
.Was only pointing out that figure is for ambient air, so as Stu says.
I should have used the phrase 'mapped with an ideal charge air of 40 degrees.'
If your engine map had no fuel at 6500rpm, then how come it took so many miles incl. track before dying?
So basically this week it's Ahmed's fault?

With regard to Steve's comments, he has got confused. As has been said, the air temp is the dyno cell temperature, which is used as part of the correction process (along with the barometric pressure). This is given on the print-out, so that you should be able to validate the barometric pressures and temps on the date the engine was dynoed to ensure that the correction figures haven't been used to amplify the power.
I know of one dyno cell that puts the temp probe very near to the engine (which obviously picks up heat from this) and gives exagerated corrected power readings. You can tell this, as it has 30°C dyno cell temps in the middle of January.
Ryan,
Regarding your choice of turbo, I think it would be better if you drive a few cars thus equipped before making a rash decision of knocking something on the head, as from your original remit, a T38 does everything YOU want it to (if correctly specced and mapped).
Yum,
I'm not disputing the fact that your car is the absolute bollocks, but there comes a time when your pride shouldn't get in the way of simple physics .
2.2 + T4 = better power than 2.0 + T38 . I think the MAD lot all know that I know what I'm doing when it comes to getting the best speed out of a car....

mike thanks for the advice, as always its taken under advisement.
I've driven several cars on T34, and only one a T38, and i must admit i didnt notice the lag difference between the two.
Escpecially on Andy Engine, aka My engine, and this was when it was only running 12psi due to weather conditions and constantly spinning up.
Im phoning UT soon and going to ask for a price on both a T38 and a GT30.

. How often do you see some of the more serious people into YBs asking for advice on here? .

yes i know, but who do you phone? no ones gonna answer these questions im going to fire at them over the phone.
Ryan: Hello, Harvey? Please Can you tell me what turbo to use so i can go buy one and go get it mapped elsewhere as i dont want mine on the Dyno, thanks all the same.
Harvey: No F-uck off you C-unt!
END OF CONVO

Ryan: Hello, Harvey.. its Ryan Pest...
Harvey: WHAT!.. the ballet dancer!!??? fffooook right off!
Ryan, you can have my T38 for £1300 if you want!
