Boost Calculator
Calculate boost pressure, horsepower gains, and performance improvements from turbocharging or supercharging. Understand how boost affects engine power output.
Step 1: Engine Details
Understanding Boost Pressure
Boost pressure is the amount of additional air pressure forced into the engine by a turbocharger or supercharger. Higher boost levels typically result in more power, but require stronger engine components and better fuel.
Step 2: Additional Options
About Compressor Efficiency
Compressor efficiency affects how much heat is generated during compression. Higher efficiency compressors produce less heat, allowing for denser air charge and more power. Turbochargers typically range from 65-80% efficiency, while superchargers range from 55-75%.

Power Breakdown Analysis
Boost Calculation Formula
HPboost = HPna × (1 + (Boost/14.7) × Efficiency)
The boosted power is calculated using a simplified formula that considers atmospheric pressure (14.7 psi), boost pressure, and system efficiency. Actual performance may vary based on engine tuning, intercooling, fuel quality, and mechanical limitations.
