Horsepower Is Not Proportional To Displacement. Horsepower Is Not Proportional To The Number of Cylinders. Horsepower Is Not Proportional To Torque. HORSEPOWER IS PROPORTIONAL TO PISTON AREA. Piston Area = (1/2 bore) x (1/2 bore) x Pi x Number of Cylinders. Changing the stroke of an engine does not change the horsepower of that engine, only the rpms the engine can rev too.By Rod Heilfron
