Supercharger Calculator
Calculate your engine’s power gains from supercharging. Estimate horsepower increase, boost pressure requirements, and performance improvements.
Step 1: Engine Details
Understanding Supercharger Performance
Superchargers force more air into the engine, allowing more fuel to be burned and creating more power. Power gains depend on boost pressure, engine efficiency, and supercharger type.
Step 2: Supercharger Options
About Supercharger Types
Roots blowers provide instant boost but are less efficient. Twin-screw superchargers offer good low-end torque and efficiency. Centrifugal superchargers are more efficient at high RPM but have less low-end boost.

Power Gain Analysis
Supercharger Power Formula
Boosted HP = Base HP × (1 + Boost Pressure/14.7) × Efficiency
The power gain from supercharging is calculated using a simplified formula that considers atmospheric pressure (14.7 psi), boost pressure, and supercharger efficiency. Actual performance may vary based on engine tuning, fuel quality, and supporting modifications.
