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 preload incorporated and a ratchet type top adjuster that will allow for the positive and precise adjustment that your driving style demands. To ease installation 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. Please note: When configured as a Dual-Piston Atmospheric Valve"
All Forge Motorsport Dual-Piston Atmospheric Valves have been designed and built with the intent of venting 100% of the residual charge air remaining in your forced induction system to the atmosphere at throttle lift. While we have incorporated many elements into the design of the Dual-Piston valves to aid in their compatibility with mass air-flow sensor equipped vehicles we cannot always guarantee that each individual’s application will be compatible with a valve that vents the charge air into the atmosphere.
Forge Motorsport nor any of it’s Authorized Distributors can assume any responsibility for any adverse effects resulting from the installation of this valve onto a vehicle whose engine-management-system whether factory or aftermarket is not capable of compensating for the loss of metered air through a vent-to-atmosphere valve such as this.
