FORGE recirculating blow-off valve

Description

The FORGE FMDV008 recirculating blow-off valve is a machined aluminium replacement for the Bosch plastic diaphragm valve. The rubber diaphragm of the factory valve splits over time and causes a boost leak. The FMDV008 replaces it with a piston design that holds boost, responds faster and can be rebuilt rather than replaced. It is the latest development of the original Forge aluminium piston valve FMCL007P.

Compared with the Bosch valve it offers higher flow and faster response, giving sharper throttle response and less turbo lag. The piston is sealed with heat-stabilised Viton O-rings and lubricated with high-temperature Mobil 1 grease. When fitted correctly, there is no engine management light. The compact design fits under the engine cover, and the two uprated springs supplied allow the valve to be tuned to your application.

With the FMDVSK blow-off valve service kit the valve can be serviced in minutes, extending its life and maintaining performance. The valve is covered by the Forge Lifetime Warranty.

Installation

Boost from the turbo goes into the side port, and the bottom port vents back to the intake. The 6 mm top port connects to the existing vacuum line. The supplied pipe is 6 mm OD / 3.5 mm ID and suits 4 mm ID vacuum hose.
