How do you calculate horsepower
WebFormula The formula below is used to calculate engine horsepower (hp) from wheel horsepower (WHP). HP = WHP * 1 / (1 – DL ) Where HP represents engine horsepower WHP is wheel horsepower DL represents drive train loss For front-wheel drive, the drive train loss is 10%; for rear-wheel drive, it is 15%; and for all-wheel drive, it is 25%.
