return newValue; Although these two terms are not a direct comparison, they are related and give you an idea of the engines size and capacity. Just enter the CC or HP and see the conversion result! Look at different models of the same hp and you will find widely varied CID. For simple numbers, lets look at converting 1 HP to cc. The A at 321 cu running at 1200rpm would be well built to make 73HP. Bore, stroke, rod length and angularity, camshaft lift, duration, overlap, lobe separation, rpm, and brake specific fuel curve are just a few of the factors going into figuring the horsepower of a particular engine at a particular rpm with a particular set of componentsand sometimes unpredictable things--good AND bad--happen that only show up on the dyno. When the term horsepower is used, people are probably referring to mechanical horsepower. Automatic Transmissions, Torque Converters & Parts, Free Engine Piston Compression A guide on volumetric efficiency values is provided below. { function findquarter3(form) A rough rule of thumb is. CC = HP*15 = 40*15 = 600 CC. The most important factors involved here are R.P.M.,C.F.M., and compression. Enter the piston stroke length. Therefore, if you convert the CC of an engine into a power output metric, then you could compare it to an electric motor. The metric and English units of measurement have quite a bit of difference, but you may need to convert both measurements in order to make proper calculations. } We also have a calculator that lets you model changes in horsepower. form.hp1.value = ""; injector size for horsepower target lb/hr.
