FYI, here is anothers Dyno Sheet with drivetrain loss on a Mustang Dyno....
This does more to undermine the figure of 20% drivetrain loss quoted above than it does to support it.
Using a factor of 1.19 to convert rolling road dyno power output to the equivalent flywheel power figure would compensate for a drivetrain loss 15.9%. If the drivetrain loss was thought to be 20%, this factor would have to be 1.25.
