Calculate precise quarter mile elapsed times (ET) for your drag racing vehicle based on horsepower, weight, transmission type, and environmental conditions.
This professional drag racing calculator uses industry-standard formulas to predict quarter mile performance. Input your vehicle's horsepower (crank or wheel), total weight, transmission specifications, and current weather conditions to get accurate ET predictions.
The calculator accounts for drivetrain losses, environmental corrections including density altitude and water grains, and transmission efficiency factors. Perfect for bracket racers, street cars, and professional drag racing teams looking to optimize their setup.
Our quarter mile calculator uses the proven formula: ET = 5.825 × (Weight/HP)^(1/3), with corrections for atmospheric conditions, drivetrain losses, and transmission efficiency. The system automatically adjusts for temperature, humidity, barometric pressure, and altitude to provide real-world track performance predictions.
