Development of our MK4 Rs for hps

[G-rig]

Those are some pretty good gains, can the same be had on mk5? I should get the cams and already have headers!

The race cars werent as extreme as anyone thinks . They dynoed 297 German hp with cams , manifold , 3inch cat deleted exhaust and software .

no headers , no cats , no pullies , no short shift , stock clutch and flywheel , V8 throttle body with larger MAF housing , modified stock airbox , solid mounts , no haldex . I wouldnt recommend increase in bore and stroke , the piston speed was getting close to the limit for the 3.2 . Stock compression cause it was running pump gas . Headwork would have helped heaps , as would changing the rod ratio and getting lighter pistons . Everything is available from VW Motorsport bar the manifold , but , it costs 3 sometimes 4 times as much as aftermarket suppliers . I still have access to it but unless your serious please dont pm me . for example , the cams are around 5000 euro and are approx 288's .

Seb...thanks for gettin on in this topic...

I read on the German R32 forum that the Mk V does not have a forged crank like the Mk IV - thats the only place I have ever seen this mentioned so might be worth further investigation before you start pumping it up.

Seb, when you say V8 throttle body and MAF, can you advise which engine that was off?

Thanks guys for the suggestions.. wont be doing anything for quite a while anyway i think.

The Mk 6 Golf R would probably be a more sensible idea unless someone comes out with an affordable & Reliable RHD SC kit, would be fun but not the best investment..

What kind of rev limit/red line did the Motorsport versions have?
Cheers,
Trent

It was from an early s4 v8 I think , Im not sure , it was used cause thats the bolt pattern that was on the manifold .

Rev limit was 8000 rpm based upon the rules of procar at the time , it was later lowered to 7300 rpm

Thanks again Seb!

That engine still had a stock bottom end too didn't it?

Were the rod bearings changed at least to go to 8000?

Thanks seb.....do you really think the throttle body made a huge difference?...iam lookin down this path...thanks for input
