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.
