BOV 1.8T 2.0T Turbo Weld or Clamp on Blow Off Valve for Audi & Volkswagen Color Red

This new valve fresh from our R&D department is the largest displacement valve that Dewhel have ever made as design as for Forge Motorsport type ! After a long trial period where we placed the valve on some of the hardest used cars around we are proud to release it for sale. Featuring a 50mm (2¡±) aluminium piston so that there are no issues with split diaphragms, we have not found the power handling limits of this valve yet ! The piston uses heat stabilised viton o-rings and high temperature Mobil 1 grease to ensure a long life with minimal wear and very long service intervals. As tested on our own Dewhel Golf Mk1 Berg Cup car, Speckys incredible 9.5 second ¼ mile Tigra, numerous Time Attack cars and a 1500bhp for Nissan GTR, the proof of its ability to handle high boost and high power applications has been proven. The vacuum barb is a huge 6mm ID and fully rotatable 360 degrees to suit any installation. This valve is suitable for custom installations only, and cannot be installed on a silicon hose. You can choose the option of either a screw on fitting or a v-band fitting with the appropriate adaptors then these will be included with your valve, which you can get welded to any aluminum pipework in your installation, ideally as close to the throttle body as possible. Available in machine finished silver or an odist black.
