Understanding Volumetric Efficiency
What is Volumetric Efficiency?
Volumetric efficiency (VE) measures how well an engine fills its cylinders with air compared to the theoretical maximum. It's expressed as a percentage and indicates the engine's breathing efficiency.
VE Formula
VE = (Actual Airflow ÷ Theoretical Airflow) × 100%
Typical VE Values
- • Stock engines: 75-85%
- • Modified engines: 85-95%
- • Race engines: 95-110%
- • Forced induction: 100%+
