We recommend servicing your valve every 3 years, or 20,000 miles, whichever comes sooner
These valves have been specifically designed and engineered, to offer extreme flow rate capability with an internal 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 valves 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 up to 34 PSI which will be dependant on the state of tune of your vehicle. 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.
NOTE: Your car may need to be mapped to run these valves, as under certain conditions the ECU adds fuel expecting the air to be recirculated back, and this creates a rich condition that may be seen as an error by the ECU. The sensitivity of this can be changed when the car is mapped.
These valves are available in a polished alloy or anodised black finish. Please select your choice in the options above when ordering.
