Well, acording to my calculations, with stock tires and the stock gearing a 7000 rpm put to the shaft of the gearbox will turn 329 Km/h on the wheels. Can anyone confirm this. I know there are always some frictional loses but the only point were i can figure rpms lost is the clutch. How much could be lost there. I know the E30 M3 Evo had a 3% loss on clutch at max speed of 248 Km/h. What's up for the M5 ?! Those 329 are surelly exagerated, but then were those rpms go?!?!?
