About Wheel Horsepower Calculator

The Wheel Horsepower Calculator helps you estimate the power your car puts down to the wheels (WHP) based on its engine power (BHP), or work backwards to find engine power from a dyno result. It accounts for drivetrain loss, which varies between Front Wheel Drive (FWD), Rear Wheel Drive (RWD), and All Wheel Drive (AWD) vehicles.
