750 bhp/603 rwhp is tempting....

[s4returns]

HPF's initial dyno with clutch slipping (stock was not upgraded at the time):



turbo upgrade testing with stock motor, stock exhaust, no nitrous, no methanol, and no IC chilling/cooling. boost level: 11psi.

with the high compression engine, this car was thought to not be able to tolerate or endure FI. but active autowerke and VF engineering have put that away. the question is, can the engine take on this kind of aggressive tuning?

now the numbers are 800 bhp/667 rwhp @ 13.5 psi:

completely stock motor? whats the displacement and what size turbo? Those are some crazy numbers for solely bolting on a turbo....wow!

[Strokin250]

not only do u have to worry about a stock motor holding that power....think about the tranny/rear end/suspension!

usually that kind of power requires changing EVERYthing out to keep it going cause generally stock stuff wont hold anything near that power... but then again, i know nothing about a BMW...

thats unbelievable power tho!
