Horsepower Required
Use the chart below to see how much net horsepower is required to run the elapsed time you want. To obtain the rear wheel horsepower simply multiply the number by 0.85. Example: If your car weight is 3,000 pounds and you want to run a 12 flat, the required net horsepower is 343 or the rear wheel horsepower required is 343 x 0.85 = 292.
