Enter the piston stroke length. } var e = parseFloat(form.dt.value); Horsepower is not recognized in the International System of Units (SI); SI uses a measurement of power (a rate at which energy is generated or used) called a watt, which is named after James Watt. Want to get a faster elapsed time, model it first on racingcalcs. A CC is defined as the size of the volume of an engine displacement in cubic centimeters. } The cubic inches of an engine is the measure of the swept volume of all of the pistons in the bores, not including the combustion chamber itself. var n8 = 0; So, if the goal is to have more power output, then a higher CC is better.
