http://www.metaris.com/hp-relations.php WebIf you run the engine at 5000 rotations per minute, (rpm), you see how much load turns on the dynamometer to calculate horsepower. Every engine has a peak horsepower – an rpm value at which the power available from the engine is at its maximum. You will often see this expressed in a brochure or a review in a magazine as "320 HP @ 6500 rpm".
