Forge Motorsport Type RS Valve - Recirculating

The Forge RS valve has been specifically designed and engineered to offer extreme flow rate capability where other valves are just not up to it. Often when engines have been tuned by installing larger turbos or even software upgrades improved turbo response can be achieved by fitting the RS valve which has the greater internal mass air flow specification utilizing an amazing 50mm (2") bore. For fine tuning there is a variable spring pre-load incorporated and a ratchet type top adjuster that will allow for the positive and precise adjustment that your driving style demands.

To ease installation, the Type-RS valve incorporates a 360 degree adjustable vacuum hose connector. With a choice of inlet and outlet connections the RS valve can be matched to your engine perfectly. This valve incorporates a unique conical, progressive rate spring that can allow for the retention of boost pressure from 7 to 22 PSI depending on the individual user's application and level of adjustment. If you are intending on running over 22psi then you will need the uprated spring, which is included in the kit.

This unique spring design will also allow for unrestricted piston travel and flow volume regardless of the amount of pre-load adjustment added to the spring. Other manufacturers valves using cylindrical springs with adjustable pre-load often experience restricted piston travel and flow volume within the normal range of valve adjustment.

Nice Valve!

I just installed this on my 2003 evo 8 and it looks good. I'm sure it will work great and it is almost no louder than the stock plastic piece. I previously had a true blow off valve on the car and wish I would have bought this sooner. If you want quiet this is what you want, also it is recirc so no screwing up the driveability like a blow off does. It only took 20 minutes to install, just undo 3 clamps and that"s it.

great product

Have been using this bov for awhile and it has held 30 psi consistently without any issues. Only complaint is there is a part throttle flutter.
