How is horsepower measured
Web13 jul. 2024 · Brake horsepower (BHP) is the most common way of measuring an engine’s power output. It is measured at the engine’s crankshaft and takes into account all of the engine’s losses, such as friction and windage. Wheel horsepower (WHP) is measured at the wheels and therefore doesn’t take into account any of the engine’s losses.
