Here, you are looking at the PERRIN Performance Recirculating BOV. This blow-off valve features adjustable relief pressure and flow control to make fine-tuning on the fly simple and quick.

DETAILS:

• 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 which 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
