Converting Rearwheel to crank HP
How could i convert Rearwheel to crank hp? What percent is lost going from the crank to the rear wheels? Anyone have a good estimate of what number i should multiply Rearwheel HP by to get Crank hp?

Assuming the standard 15% loss for an M6 and 20% loss for A4 (some say 17-20%)
For an M6: RWHP / .85 = FWHP
For an A4: RWHP / .80 = FWHP
An M6 car making 340rwhp would be making 400 at motor (340 / .85 = 400)
