      Note: the elapse time is the approximate amount of time that your vehicle should be running. Although many factors influence elapse time, the main factor is traction.

      In most cases, if your vehicle does not have enough traction, your elapse time will be higher than the estimated time.

      The other extreme is also possible and usually occurs when you are using racing slick tires.

      Our horsepower calculation is correct by the definition of horsepower. Horsepower is a measure of the force required to accelerate a weight to a known speed in a known distance. This means that the generated horsepower provided by this calculator, is the actual horsepower at the rear wheels.
