Blow Off Valves – Essential for Turbocharged Performance
Blow off valves, also known as BOVs, are vital components in any turbocharged setup. They release excess boost pressure when the throttle closes, preventing compressor surge, improving turbo longevity, and enhancing throttle response. Whether you're tuning a street car or building a motorsport-ready engine, a high-quality blow off valve is a must-have.
Why Upgrade Your Blow Off Valve?
Stock bypass valves are often designed for quiet operation and lower boost levels, making them insufficient for tuned engines. Upgrading to a performance BOV provides several advantages:
- Prevents compressor surge and protects your turbocharger.
- Faster throttle response between gear shifts.
- Handles higher boost pressures in tuned setups.
- Distinctive sound loved by turbo enthusiasts.
Types of Blow Off Valves
- Vented (Atmospheric) BOVs – Release air directly to the atmosphere, producing the signature "psshhh" sound.
- Recirculating BOVs – Route excess air back into the intake, ideal for MAF-based systems and quiet operation.
- Hybrid BOVs – Combine atmospheric sound with recirculation efficiency for versatile setups.
Applications
- Turbocharged petrol and diesel engines
- Performance street builds and daily drivers
- High-boost drag, drift, and time attack cars
- Motorsport applications requiring fast boost recovery

Installation Tips
For optimal performance of your blow off valve:
- Ensure proper vacuum source connection for accurate actuation.
- For MAF-equipped cars, choose a recirculating or hybrid BOV to avoid AFR issues.
- Pair with upgraded intercoolers and boost controllers for maximum tuning potential.
- Check spring tension regularly if running variable boost setups.
