Ok...ACTUALLY:

brake horsepower:
(bhp) A measurement of the actual usable power (not calculated power) measured at the output shaft (usually the crankshaft) rather than at the driveshaft or the wheels. Thus none of the auxiliaries (gearbox, generator, alternator, differential, water pump, etc.) are attached. It is called the brake horsepower because the shaft power is usually measured by an absorption dynamometer or "brake." This is not the brake on the vehicle's wheels but a testing device applied to the shaft. This instrument is applied to stop or absorb the rotation of the output shaft and returns a value. Compare SAE gross horsepower and SAE net horsepower.

So basically we have discovered that...

Brake HP is = HP at the crank.
Wheel HP = I think its obvious.

hMmm....i thought i got it but now im a bit confused...

i thought back then they used some kinda way to measure bhp by measuring the friction of the BRAKES..

whp is generally measured by dyno < people say its at the wheels...but i think its more like traction...tires traction and wheel weight might b factors too>

TECHNICALLY brake horse power is the same thing as SAE Gross horse power, but nowadays the European magazines use it interchangeably with our "hp" which stands for SAE Net horse power.
