when companies avertise their cars the HP they list and retail by is the crank Horsepower which is an estimate of how much power the engine is making. However by the time the power is tranfered from the engine to the wheels theres gonna be a loss of power. Usually 15percent on rear wheel drive cars and 25 on four wheel drive cars.
Wheel HP is the rating of HP people are after cause it represent the actual power we are getting and feeling. A stock Z4m usually dyno at 250-260 Wheel horse power. In ^ case he got 305 whp from the dyno which by an estimate is about 350->360 crank hp = 30 more than factory claimed stock crank hp
