997s stock numbers

355 hp at 6600 rpm

295 lb/ft torque at 4600 rpm

what does that equate to the wheels ?

 

I never had got around getting a baseline on my C2S
Maybe someone else on this board has already dyoed their car and can chime in
However if I had to guess it would be around 300-320hp 255-260tq at the wheels on the Dynojet

 

I believe that the generally accepted "seat of the pants" rule for the conversion of Brake Horse Power (BHP) to Rear Wheel Horse Power (RWHP) is to allow 16% reduction for drivetrain loss.

Therefore, 355 BHP(1-.16) = 298 RWHP and 295 BFPT(1-.16) = 248 RWFPT.
