brake horsepower
n. Abbr. bhp or b.hp.

The actual or useful horsepower of an engine, usually determined from the force exerted on a friction brake or dynamometer connected to the drive shaft.

So is BHP measured at the crank or at the wheel?

 

Since i have been in the car modification bussnies Ive alwasy known for BHP to bea real time at the wheel HP, so im not sure about that definition. Dont feel so bad we all learn something new every day
