This Blow Off, or dump valve, is for the Renault and Nissan Turbo engines that have the electronically controlled bypass valve (OEM Part no. 144839204R). 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. The Forge valve is piston based, there is no diaphragm to fail, and of all aluminium billet 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 is an atmospheric valve which makes a sound when dumping boost
