Default power figures?

If a motor is producing 364bhp 332Lbft at the wheels,what are the figures at the flywheel?

What is the car? most of the time you go with between 20-25% losses, but it all depends on the rolling road etc, and normally they should give you the fly and wheel figures.

About 12% on a Rototest hub to flywheel power.

Hub figure has less losses than wheel figure, so hence the difference in overall loss % when comparing between wheel and flywheel.

If you are comparing apples with apples, I much prefer a hub dyno..... takes out some more of the bull**** factor!
