Hp vs. Rwhp

RE: Hp vs. Rwhp
There are two horsepower number commonly thrown around in conversation. Horsepower at the flywheel/crank (bhp) and horsepower at the wheels (rwhp). Bhp is what the engine makes by itself. Rwhp is what is measured when the car is strapped to a dyno. Rwhp is always less than bhp because some of the energy the engine creates is used up turing the accessories, driveshaf t, and (primarily) the transmission. You lose about 15-20% horsepower before it reaches the wheels. You can lessen the loss by having lighter-weight rotating parts that require less energy to start spinning and keep spinning.
