Inefficient factory blow off valves (BOV) can hinder boost response during shifts and can damage your expensive turbo charger. PERRIN offers several choices for owners to choose the best solution to the problem.
Perrin Red Recirculating Blow Off Valve WRX 02-07 / STI 04-15 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 boost in your system, without ruining response by dumping too much
boost. The PERRIN Blow Off Valve 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 air within the boost
system without reducing turbo response. 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 surge. 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 blow off valve. Included with every PERRIN Blow Off
Valve are the necessary components to make this a direct bolt-on for your WRX/STI.
Each blow off valve is pre-set out of the box to work perfectly with every application,
so no adjustment required. 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.
