How Our Calculator Works
Physics-Based Calculations
Our calculator uses fundamental physics principles combined with real-world automotive data to estimate horsepower. We employ multiple calculation methods including acceleration-based formulas and dyno correlation algorithms.
Power = Force × Velocity
Force = Mass × Acceleration
Acceleration = Change in Velocity / Time
Advanced Features
- Multiple calculation methods for different scenarios
- Aerodynamic drag compensation for high-speed calculations
- Performance category classification
- Top speed and fuel economy estimates
- Downloadable results for record keeping
Accuracy and Methodology
What Makes It Accurate
- Validated against thousands of dyno results
