OVERVIEW

Adjustable relief pressure and flow control make fine-tuning on the fly simple and quick with the PERRIN BOV/BPV.

HIGH FLOW

With large 1.225" inlets and outlets, the PERRIN Blow Off Valve is sized perfectly to relieve any amount of boost pressure without fear of compressor surge. Don’t be fooled by giant oversized blow-off valves, these inlet and outlet sizes were chosen to ensure the perfect balance of flow and to maintain the boost in your system, without ruining response by dumping too much boost.

ADJUSTABLE RELIEF PRESSURE

The PERRIN BOV/BPV cap features adjustable spring tension, which allows for an adjustment when the blow-off valve vents. A looser setting will make it act smooth and more like stock. Setting it harder will cause it to vent later and with significantly increased boost levels. This adjustment is important in maintaining the air within the boost system without reducing turbo response.

ADJUSTABLE FLOW CONTROL

The unique design allows you to control the volume of air released when the blow-off valve vents. Adjusting the volume of air helps maintain the perfect amount of boost in your system during shifts without causing compressor surges. Venting too little can damage the turbo, venting too much air can make the throttle less responsive. This adjustment is independent of the relief pressure allowing for a totally customizable BOV/BPV.

RECIRCULATION IS JOB #1

It is vital that a blow-off valve for your WRX/STI recirculates the air back to the intake track to maintain proper air-fuel ratio and driveability between shifts. While this can be set up as a vent-to-atmosphere style blow-off valve, we only recommend that on cars running aftermarket Speed Density type tuning (cars without mass airflow sensor).

CONSTRUCTION

The PERRIN Blow Off Valve cap, piston & flange are all CNC machined from 6061 Billet Aluminum. The PERRIN Blow Off Valve body is CNC machined from a single block of aluminum. This makes for a clean look that reduces potential failure points and leaks without additional parts.

FINISH

The PERRIN Blow Off Valve body comes in either a black or red anodized finish and the cap comes black anodized. The anodizing keeps the blow-off valve looking great during its lifespan. The blow-off valve body and cap are pad printed in vibrant lettering to make it easier to read.
