I have seen some quotes on this but I wanted everyones opinion for a spreadsheet Grinder and I are coming up with.

Mostly grinder

I have heard that you loose 20% with the Mini Cooper S in the transfer of power to the wheels from the crank. Does this sound right?

Based on Stock Wheels, Tires, clutch etc.

Anyone have official ratios?

Please post what you see for base line Wheel HP on dyno runs.

I see:

1. 139.9 Magnaflow Base
2. 137.0 Evotech

Please add any you find and make sure they are not corrected to Flywheel HP.

To me this looks like there is a 13-15% loss.

What does everyone think?

To my knowledge, 15% is the most common standard.

RWD should have higher drivetrain loss , on avg FWD tend to lose around 15% like already said . My car dynoed 133.4whp bone stock, stock crank hp rating was 158 which is almost a 15% difference this was one a 11 year old motor
