Turbo Boost HP Equation:
From: | To: |
The Turbo Boost HP calculation estimates the horsepower increase from forced induction (turbocharging) based on boost pressure and naturally aspirated horsepower. It helps predict engine performance with turbo modifications.
The calculator uses the boost pressure ratio equation:
Where:
Explanation: The equation calculates the pressure ratio (boost pressure relative to atmospheric pressure) and applies it to the base horsepower.
Details: The boost ratio determines how much additional air (and thus fuel) can be forced into the engine, directly affecting power output. This is fundamental for turbo system design and performance tuning.
Tips: Enter your engine's naturally aspirated horsepower and desired boost pressure in psi. Both values must be positive numbers.
Q1: Is this calculation exact?
A: This provides an estimate. Actual results depend on turbo efficiency, intercooling, engine tuning, and other factors.
Q2: Why 14.7 psi?
A: This represents standard atmospheric pressure at sea level, the reference point for boost pressure measurements.
Q3: Does this account for turbo lag?
A: No, this calculates peak potential horsepower, not power delivery characteristics.
Q4: Can I use this for superchargers?
A: Yes, the same principle applies to positive-displacement superchargers at equivalent boost levels.
Q5: What's a safe boost level?
A: This varies by engine. Consult your manufacturer or engine builder before increasing boost pressure.
