Estimated Trap Speed
Predict your car's drag strip performance before you even hit the track. Our quarter mile calculator uses the proven Patrick Hale and Roger Huntington physics formulas to estimate Elapsed Time (ET) and Trap Speed.
In drag racing, your power-to-weight ratio is everything. By entering your vehicle's total race weight (including driver) and wheel horsepower, you can simulate how weight reduction or engine tuning will affect your 1/4 mile times.
