Hi everyone NEW S2 here

[S4turbo]

Engine pics not working......

I have plotted your data (100 oct) against many other 3071, 3076 and 3040 turbo plots, and I must say that it does look a bit too good to be true, it spools as early as a 2871 and has more torque than any other gt30 based engine that I have seen dyno plots of (including 2.6 liter engines with gt3076 turbos). But I don't think I have other 100 octane plots ither.

Can I ask about your CR, and if you have any graphs of the 93 octane rund?

Anyway, looks like a really well tuned car, extremely so if the data is correct!

Regards, Johan

Here is more info for 100 octane map, page 3 in a middle, I do got to contact Marc to get pump gas map info he should have all the plots.

Little update, got some CF

Little update, got some CF stuff in, Thanks Marc for taking time to deliver CF in person. Got rotor hats and rotors, still looking for Boxter s calipers and 5sp 01E.

Janis, are U using a N75 solenoid valve to control the wastegate ?
I've ran into Problems with the N75 on high boost (above 2 bar).
The N75 just leaked alot.
I take it you not experiencing any problems with the N75 -

100 octane race gas 30PSI peak tapered of to 25 PSI to the red line 440WHP

Is that with the RS2 manifold and standard down pipe

440 whp on a 3071?

hmmm 550 bhp crank which is more bhp that a GT3076 aks GT30R is rated for and done on a standard RS2 manifold?

Is that with the RS2 manifold and standard down pipe

eeek .. i only managed about 460 crank hp with my 3071.
my setup used tubular exhaust manifold and 3inch down pipe- 7a ex cam.
boost was lower thou.

Exactly...

Another forum memeber made 420bhp at the crank with a RS2 manifold and thats good going with a 3" dp.

Also just read this quote about back pressure on a Sport quattro replica

The exhaust manifoild on the picture if from MTM (sport quattro), but at the dyno that manifoild and the kkk F1 turbo stopped at 380 HP,with very high back pressure , so i changed it for a tube type manifoild and a Turbonetics E50 turbo, then i got 520HP

WG was almost shut, with 1.9 bar spring I needed to turn adjuster bolt 2.5 turns down, another wise it was creeping open. On my DP it starts out as 2.5’’ and then goes to 3”. EGT s was safe I have probe in a EM in a 5th cylinder runner.

I'm not sure what that quote proves... that you can change out your manifold AND turbo and make lots more horsepower

Not a lot of new news there to me..

Yes N75 no boost spikes or any problems

01E is in a car, spend some time to make mounts, now working on a shifter, should be up running this week

Inlet Manifold Query ?

Janis,

What engine is your inlet manifold from, or is it a custom one off? If so who made it?

Thanks.
