Perrin Recirculating Blow Off Valve BOV - Evo 8/9/10 - Black

CONSTRUCTION

The PERRIN blow off valve cap, piston & flange are all CNC machined from 6061 Billet Aluminum. The body is CNC machined from a single block of aluminum. No additional bolt on pieces means we eliminate potential leaks.

ADJUSTABLE RELIEF PRESSURE

The PERRIN BOV features an adjustable cap which allows you to tailor when your BOV releases. Set it up loose for a smoother release of boost at light loads and RPM. Or crank down the cap to release boost only at higher boost loads and RPMs. This feature is independent of relief volume.

ADJUSTABLE RELIEF VOLUME

Our unique design allows you to adjust the volume of air released when blowing off. This adjustment is independent of the resistance to blowing off. Venting too little can damage the turbo, venting too much air can will make the throttle less responsive.

MAINTENANCE

The PERRIN blow off valve requires very little maintenance but when needed, it's very easy and quick to disassemble the blow of valve with no special tools required.

RECIRCULATING OR VENT TO ATMOSPHERE

This universal fitment has large 1.325" tube connections for easy installation. Simply disconnect the recirculatory hose and let your blow off valve vent to atmosphere on cars using speed density type ECU's (Cars with no MAF)
