PERRIN Recirculating Blow Off Valve - Red

---

SPECS:

• Cap, piston, and flange are CNC machined from 6061 billet aluminum materials
• Blow off valve body is CNC machined from a single block of aluminum
• Anodized red finish
• Large 1.225" inlets and outlets and is sized perfectly to relieve any amount of boost pressure without fear of compressor surge
• Adjustable relief pressure with adjustable spring tension allows for an adjustment when the blow-off valve vents
• A looser setting will make it act smooth and more like stock while a harder setting will cause it to vent later and with significantly increased boost levels
• Adjustable flow control 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
• Recirculating the air recirculates the air back to the intake track to maintain proper air-fuel ratio and driveability between shifts
• Low maintenance and is quick and easy to disassemble
• Direct fit and pre-set adjustment

 

MUCH STRONGER THAN THE OEM UNIT WITHOUT THE NOISE

The PERRIN Performance Recirculating BOV features a strong aluminum body with a billet aluminum piston that is much more robust when compared to the OEM bypass valve. This unit has been designed with adjustable relief pressure with adjustable spring tension to allow for an adjustment as the blow-off valve vents with increased boost levels. This will also help maintain the perfect amount of boost in your system during shifts, and the recirculating operation will also help maintain the proper air-fuel ratios between the shifts. An excellent upgrade you can perform on your daily driver, weekend show car, or purpose-built race car.
