Neon SRT-4 Blow Off Valve

Forge Motorsport is proud to release the new line of valves for the Dodge Neon SRT-4. With blistering performance right off the showroom floor there is no doubt that the Neon is a force to be reckoned with. All Forge Motorsport Single-Piston and Diaphragm 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. The engine management system of the Neon SRT-4 is designed to allow for the use of a single diaphragm/piston atmospheric valve without any detrimental effect on the performance of the vehicle. It is a normal occurance for this valve to be open/venting at idle and vacuum, and we highly discourage the use of stiffer valve springs to keep the valve close at idle/vacuum, as this can create compressor surging at full-boost throttle lift. We have conducted tests on our valve springs in comparison to the springs in the OEM/Mopar valves, and have found that the Green spring supplied in this valve is sufficient for almost any boost pressure on this application. Forge Motorsport nor any of it’s Authorised Distributors can assume any responsibility for any adverse effects resulting from the misuse of valve springs in this valve in an attempt to keep this valve closed at idle/vacuum.

Type RS Valve- Atmoshperic

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 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 34 PSI depending on the individual user's application and level of adjustment. 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.

Valve Spring Tuning Kit

Now you can fine tune your Blow Off/Diverter Valve to the exact needs of your engine with this complete tuning kit. Your valve tuning kit you will find four springs and three spacers. The strongest spring is the red, followed by the blue, yellow and finally the green which is the weakest. The spacers enable you to fine tune the settings between two spring tensions if required. We normally supply our valves, unless requested differently, with a spring that will match the tension of the manufacturer’s original fitment valve. However, as many owners undertake tuning modifications some may wish to re-tune the valve characteristics to suit a given application. If you are finding that the valve is dumping more than required or you are loosing boost pressure it is normally an indication that a stronger spring is required. Conversely if the valve is failing to dump it may be necessary to install a weaker spring. If during this tuning of your valve you are faced for example with the red spring being to strong and the blue spring to weak, you can add the spacers to the blue spring to increase the tension by small increments, thus achieving a setting between the red and blue springs. Valve Spring color coding Green - 5-15 PSI Yellow - 15-23 PSI Blue - 23-30 PSI Red - 30 + PSI The above figures are estimates only and should only be considered as a guideline Please note - fitting a stronger spring into a valve will not increase boost pressure unless existing pressure is being lost. Failure to allow the valve to operate by installing a spring which is to strong may cause damage to the turbocharger. Please note - the red coded springs should not be installed in the DVR or DV007 diaphragm valves
