Horsepower from Trap Speed Calculator
Estimate your vehicle’s horsepower based on quarter-mile trap speed and weight. This calculator uses physics-based formulas to provide accurate power estimates for your car’s performance.
Step 1: Vehicle Details
Understanding Trap Speed
Trap speed is measured at the end of a quarter-mile drag strip. It’s a good indicator of a vehicle’s power-to-weight ratio and overall performance potential.

About Correction Factors
Atmospheric conditions affect engine performance. Higher elevation, temperature, and humidity reduce air density, which can decrease horsepower output by 10-15% or more.
