HaleQuarterMileCal

If you're thinking of entering your car into a drag race and are wondering how well it would perform, then this quarter-mile calculator is for you. It combines a quarter-mile time calculator and a quarter-mile speed calculator. Using only your car's power and weight, it will estimate its 1/4-mile elapsed time (ET) and final speed (trap speed). With this quarter-mile calculator, you can:
Set a target time for your drag race.
See how a power upgrade to your engine affects your ET.
Learn how reducing the car's weight affects its performance.
