This valve is a full replacement recirculation valve (i.e. quiet) that integrates seamlessly with the OEM electronics and results in no detriment in performance, and absolutely NO fault codes or check engine lights, which isn’t something that can be said of our competition!Like our full replacement recirculating valve option, this valve is fully engineered to remedy the failure issues experienced with the OEM solenoid valves when their diaphragm may rupture which results in a boost leak. The later revision OEM valves have a longer life but ultimately the plastic brittles and in extreme circumstances, parts of the plastic can break off. Our valve uses full billet alloy construction with a piston based internal design that provides for significantly improved reliability over the OEM valves along with lightning-fast response. It has also been proven in cars running over 600bhp!This new valve has a very short overall installed height, which enables fitment of this atmospheric valve into the tight space between the turbo and the inlet hose from the air filter, older larger valves and sandwich plates will not fit this engine.In The Box:1 x FMDV32 Valve1 x Wiring Harness1 x Solenoid, Bracket, and Screws1 x Blue Spring (Uprated)1 x 5mm Brass T Piece12 x Cable Ties1 x 1500mm Length of 4mm Vac Hose1 x Forge Keyring and Sticker

Forge Type RS Valve - Atmospheric

Forge

We recommend servicing your valve every 3 years, or 20,000 miles, whichever comes soonerThe 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 acheived by fitting the RS valve which has the greater internal mass air flow specification utilising 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. 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 with 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.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.

Forge Blow Off Valve for Hyundai and Honda Civic

Forge

We recommend servicing your valve every 3 years, or 20,000 miles, whichever comes soonerBlow Off Valve for Hyundai Genesis Sonata and Kia Sportage and Optima.The Forge direct replacement blow-off valve is designed to be a more durable and performance oriented valve than the OEM unit. The OEM valve is suitable for stock boost levels for a period of time, however, once boost pressure is raised, and after prolonged use, the stock valve will no longer be adequate. Raising the boost output of the vehicle will have a number of effects on the OEM valve. First and foremost, the additional boost pressure will quickly exceed the capacity of the OEM spring to keep the valve closed under higher boost levels. Since you cannot change the springs in the OEM valve, it cannot be adjusted for higher boost levels. Secondly, the additional heat generated by the increased boost will quickly deteriorate the OEM rubber valve diaphragm, which will also lose strength with repeated oscillations.The Forge valve uses full billet aluminum construction and Viton silicone o-rings that will withstand the highest boost levels and repeated abuse. It is also tunable for varying boost levels with the included spring tuning kit. If there is ever a problem with the valve such as a torn o-ring, replacements are available free of charge, and the valve is fully rebuildable.As the Genesis Coupe 2.0T does not use a MAF (mass air flow) sensor, there is no reason that the residual boost pressure at throttle lift cannot be vented to the atmosphere such as with this valve. The engine management does not meter the air volume entering the engine, so this residual pressure can be discharged without any adverse affects on the performance or driveability of the vehicle. Additionally, the valve being open at an idle or vacuum condition is a normal occurance, and is not indicative of a leaking valve. If the intake manifold is in vacuum, even while cruising at speed, the valve may be open. The OEM valve operates in this same manner, however, it is just not visible/audible because it is recirculating instead of vented to the atmosphere. Using a stiffer spring to keep the valve closed at a vacuum condition may result in too stiff of a spring tension to effectively discharge pressure at a throttle lift condition.

Forge Blow Off Valve and Kit for BMW 135/235 F20

Forge

We recommend servicing your valve every 3 years, or 20,000 miles, whichever comes soonerThis Blow Off, or Dump valve, is for the BMW 135/235 N55 3.0 Turbo engines 2012-2013 are PWG (Pneumatic Waste Gate) , that have the electronically controlled bypass valves. It is recommended for any vehicle where the boost pressure has been increased by an ECU software upgrade and for unmodified vehicles operating in warmer climates, as a solution to the many failures that have occurred. Unfortunately the failure doesn’t always result in a check engine light as the valve can still be blown open by the boost pressure, so you may not be aware that you are losing power due to this. This prevents the diaphragm from sealing.Our alternative is a fully engineered solution offering both significantly improved reliability. Our valve is piston based, with no diaphragm to fail, and of all aluminium construction, it replaces the original unit with a pressure/vacuum operated piston valve that still also retains the desirable OEM ECU control, over valve actuation.

This valve soon became the most copied and imitated in the valve marketplace.The FMDV008 turbo recirculation valve is the result of 25 years of continued experience and engineering expertise. With the reputation for innovating and manufacturing the best automotive valves in the world, you can be certain that there is currently no better replacement valve available. Forge's recirculation valve features a greater flow rate than the OEM Bosch valve, as well as a faster response time, due to its revised design. 10/10, replacement for my stock 1.8t mk4 Golf DV, build quality is over the top  Great bit of kit, well made, easy to service  I bought the FMDV008 and the quality is outstanding from the packaging to the product itself, really is a piece of quality kit, easily fitted with the simple instructions included.... and it really does improve the performance By using the associated service kit (FMDVSK), as seen below, the life of the valve can be extended, and the performance can be maintained. With a lifetime guarantee, you can be sure the valve is reliable for your car.It is fully customisable to fit your application with two uprated springs provided in the kit. Forge Motorsport's improvement on the original valve has a compact design, meaning easy fitment under the engine cover.
