whp is wheel horse power. it's the number you'll get if you dyno your car. bhp I think stands for brake horse power, it is the number you'll get from the car makers, like the gts is 180 hp, it's in bhp and not whp. Whp is a little less than bhp. I hope that explains, anybody want to add something ?

Say the gts is 180 hp stock, if you put it on a dyno it should give a little over 160 whp I believe

Brake horsepower is taken from braking the the car down (the rollers on the dyno do that) until the revs drop hence the word "brake".

Wheel Horsepower, is how much horsepower with the weight of the car, not too sure about BHP though

No. Dynos get your power reading by running your car through a brake of known resistance. This is Brake Horsepower (http://www.bartleby.com/61/14/B0451400.html). In essence most of the wheel horsepower figures are actually wheel (brake) horsepower since they where taken from brake dynos.

Wheel horsepower is the left over horsepower after mechanical loss (power loss from the drive line or engine auxillaries). Most RWD cars will have around 17% power loss from the engine to the wheels and FWD cars will have less losses (shorter driveline). Automatics will lose more power than manual transmissions (around 20% or more on RWD cars). The weight of the car is not part of the equation. wink
