Ram Air Theory
How Ram Air Works
Ram air systems use vehicle speed to create positive pressure in the intake system. As air hits the front-facing intake, it's compressed and forced into the engine, increasing air density and allowing more fuel to be burned.
Velocity Pressure Formula
q = 0.5 Ć Ļ Ć vĀ² where q is dynamic pressure, Ļ is air density, and v is velocity
Real-World Considerations
- ā¢ Ram air effects are most noticeable at high speeds (80+ MPH)
- ā¢ Actual gains depend on intake design and engine tuning
- ā¢ Benefits may be offset by increased aerodynamic drag
- ā¢ Cold air intake systems can provide similar benefits
