yah i have no idea what whoarspower is.
here is a definition of bhp though:
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.

There is brake horsepower and real wheel horsepower. Brake horsepower is significantly higher and usually what you hear when people talk about hp. Brake horsepower doesn't have the drag of all the belts and the differential and tranny. Real wheel horsepower is what you actually have.

Always wondered why it was "brake" hp, good research job, sean!
I can't remeber exactly how much less rwhp is than bhp, but for some reason im thinking 15-35%, or some where in there. Any body know? I know it varies slightly from car to car, but on average, or just for BMWs.... any one know?
