Real-World Note
This calculation assumes 100% adiabatic efficiency and perfect intercooling. Actual gains are typically 15-20% lower due to heat and mechanical losses.
Overview
Forced induction increases engine power by forcing more air into the combustion chamber. Turbochargers use exhaust gases; superchargers are belt-driven. Understanding boost pressure helps estimate horsepower gains and engine stress.
💡
Pro Tips
Compression ratio needs to be lowered for high boost applications to prevent 'knock'.
Intercoolers are crucial to keep the air-fuel mixture cool and dense.
Fun Fact
Did you know? Every 1 PSI of boost is roughly equivalent to a 6-7% increase in engine power.
