I need to know what the most BHP a 2wd saph cosworth would give running 28psi. Sounds like a strange question but I need to know so read on and bare with me..

Basically a mate had one a few years ago and it (admittedly) was very fast (I had a modded 2wd at the time and it was a different world) but someone told him it was around 400bhp. I've always been pretty sure it wasn't..

The spec was..

hmm, not a lot..

I remember it was running blue injectors and IIRC a 200 block. I can't remember the chip/map (and neither will my mate) but whatever it was the car was running 28-30 psi when we picked it up so I presume had felling to accommodate.

Other than the injectors and boost level everything appeared standard (intercooler, turbo etc)

Now the car was ballistic, and a friend told him it was knocking on feeling 400bhp.

I've always thought with the turbo and intercooler limiting things it would be nowhere near this level, it did feel very healthy though.

I was just interested in a sort of 'best case scenario' of the power level from someone 'in the know' reason being is because he's now buying an Evo 8 and I'm trying to convince him he'll easily get some decent power out of it. But when I mention 380bhp he harks back to the 400bhp cossie.

I suspect if it was a 'good one' it would have been running circa 340bhp?
