Quarter Mile Drag Racing Calculator


The Quarter Mile Drag Racing Calculator is a convenient, fast, and easy way to calculate the quarter mile ET (elapsed time) and HP (horsepower) in the quarter mile drag race. All horsepower in the calculator is measured at the flywheel. The car manufacturers use this number because it is 15-20% percent higher than the horsepower at the wheels. Have Fun!

Enter car's weight (lbs) and horsepower to find your best time.
