I reckon (hope) we will see 350 crank hp, engine builder thinks we will see 400

Good luck. I'll be interested how the Augtronic performs as I'd like to go to a MAF/MAP based setup. Is that a RS500 size intercooler, I think the standard Cosworth one is smaller than the original 944 item. I've got a standard Cossie intercooler in the garage from when I fitted a 4x4 version on my RS Cosworth 20 years ago.

320 rwhp im guessing.

What boost levels are you running?

Cheburator

It is off a RS500, which made 500rwhp, so it must flow fairly well.

1bar to start with and see how we get on...

Paulyy

1 bar? I'll stick to my 320 rwhp You'll get some quick spool though. would be real fun to drive.

It is a full blown race car at 1100kg, with the emphasis on reliability - it should be able to survive 40mins qualifying at flat out and up to 3hrs races at flat out again. The beauty of the Augtronic ECU is that it allows switching between different maps at the press of a button on my laptop. May have to write several maps...

Still no call from the mapper - getting anxious now...

Is Tom at Augtronic doing the mapping?

At 1 bar I am going to guess 300 at the wheels

Paulyy

at 1bar with that current setup, you should have a strong motor. I'm actually surprised you kept an older turbo on a modded engine. You would have more gains going to a garrett GT/GTX series turbo.

I'm curious too!!

Cheburator

Tom is doing the mapping indeed.

This 944 is almost a side project. I bought it as stop gap race car, then I realised it is eligible to race in the Youngtimer in Germany, mainly on the Nurburgring and the rest is history.

Did one test day in it - ran well, but smoked, pulled the head - valve guides shot, valves themselves shot, and cylinder 4 with a score mark. The car was otherwise so good, I decided to actually throw some cash and attention at it.

Decided to sleeve it and drop Woessner pistons, then we thought about working with the head within the rules. That led to a bigger throttle body and then was offered the freshly built hybrid K26/K27 for US$500. Hence we went with it.

We are fairly limited to what we can modify - there is a local 2.5 16v Turbo which has done 25,000 miles while pushing 420Whp, but I cannot be seen with the superior 16v head, or even the 2.7 intake valves or a ball bearing turbo or a 6-spd 968 box...

300 at 1 bar. Depending on outside temp maybe 320.

290 at the wheels.

So it's as big as, and sitting right in front of your water radiator ? The RS500 had much more airflow to the intercooler than a 944 so I wouldn't get too excited about that 500 bhp .

So its 9.20 pm now what's the results?

When are you going to put your car on the rollers ?
