WebTo use this horsepower calculator enter the mph trap speed at the 1/4 mile mark from one of your dragstrip ET slips. Then enter the total weight of your vehicle, as raced, including the drivers weight. The best way to get the weight is to weigh your vehicle at the track with the driver seated in racing position. Web[Figure 1] This comparison is expressed as a ratio, hence the term compression ratio. Compression ratio is a controlling factor in the maximum horsepower developed by an engine, but it is limited by present day fuel grades and the high engine speeds and manifold pressures required for takeoff.
