Drivetrain Power Loss Formula
#21
FWD is the most efficient setup isnt it? (Since the power doesnt have to change directions?)
Doesn't change direction???!!!! You have got to be kidding.
The engine is sideways. The trani has a chain drive that makes a 180 degree turn.
It is much more direct but not much more efficient.

Automatics will always be less efficient than a manual gearbox because automatics have to use some of the engine power to run the pump in the transmission. How much of a difference depends on the design of the transmission. You will never have an conventional automatic match the efficiency of a manual gearbox because of the pumping losses.

The Brake was a tool used to measure engine HP.

Net HP and Brake HP.
Centrifugal pump formula:
BHP = Flow(GPM) X TDH(FT) x SG /3960xEFFICIENCY(%)
Net horsepower used to be used to rate auto engines and it is always higher than the actual brake horsepower which takes into account all the accessories including the exhaust and intake systems.
They are both measured at the flywheel before any losses caused by the rest of the drivetrain.
