This is a horsepower calculator that I made. It is a very rough estimate of horsepower, due to the fact that it can't take into effect things such as altitude correction, gearing, compression, traction, etc. It has been said that your e.t.'s are about traction, while your trap speed is about horsepower. If you notice cars at the track, the cars that will smoke them off the line can still cross the finish line at the same speed. This program has a spot for horsepower by e.t, but also by trap speed. However, if traction isn't a problem, you should produce similar results. Anyways, download this program, take a look, tell me what you think, and enjoy.
