Does torque@wheels readings change by the about (ie in RR guesses, lol) the same amount from flywheel to wheels like BHP does or?

Also what can we say is a fair 4wd transmission loss? 15%? 20%?

Dont need a perfect answer, just roughly as trying to compare 2 results, one with just wheels results (RR), and one with just flywheel results (engine dyno).

 

i seen afew subaru shootouts and they lose about 80bhp due to transmission according to there measurements, some lost nearly 1 hundred bhp from flywheel to wheels, and before anyone says bollocks it was in banzai or summit like that and it was all on the rolling road and they all lost about the same

 

I lost 35.2hp in the Esccos last Mon.

 

IMO i cant see more than 10% losses, but everyone (well most RRs) seems to claim 15-20% tho...
