WHP = Wheel Horse Power
The true measure of horse power is what comes out at the wheels. You would lose power from the engine to the wheels, so the amount that get's cranked out, isn't the amount that you actually have.

Damn, we all posted at the same time! So, as the other guys said!

At least the current SAE net HP ratings are much more accurate than the old gross HP ratings used in the 60's. The gross ratings were taken on an engine dyno w/ and did not require things like the accessory belts (which sap power) to be attached. They may have used a water tower to keep the engine temp down too.
Now, I believe the engine has to be rigged up how it would be in the car, with all belts and stock cooling system.
RWHP = rear wheel horsepower
BHP = brake horsepower, seen at the flywheel
For AWD cars like the Mitsu Evo, the engine is rated around 276 hp but on 4 wheel dynos, they put out 190-200 hp to the ground.
