Forge Motorsport Blow Off Valve for Peugeot / BMW Mini 1.6 Turbo Engines
This Forge Motorsport Blow Off Valve is designed for the Peugeot / BMW Mini 1.6 Turbo engines, specifically for the Peugeot 207/307/308 GT Turbo and BMW Mini Cooper S Turbo fitted with the N14 engines. It is suitable for a range of Mini models including the Mini R56 Cooper S, Mini R56 John Cooper Works, Mini R57 Cooper S, Mini R57 John Cooper Works, Mini Clubman R55 Cooper S, and Mini Clubman R55 John Cooper Works.
The valve is recommended for vehicles with increased boost pressure due to an ECU software upgrade, as well as for unmodified vehicles operating in warmer climates. It offers a reliable solution to common OEM solenoid valve failures, such as a split diaphragm and a brittle diaphragm retaining ring.
Forge Motorsport’s alternative is a fully engineered solution with improved reliability, featuring a piston-based design with no diaphragm to fail. The valve is constructed from aluminium and replaces the original unit with a pressure/vacuum operated piston valve, while retaining OEM ECU control over valve actuation. It is a proven solution in the VAG scene and offers interchangeable springs for different levels of boost.
The product is available in machined alloy finish and comes with a range of components including the FMDVR56A Valve, Mini Wiring Harness, Solenoid, Bracket, Screws, Vacuum Tap, Uprated Blue Spring, Cable Ties, Vacuum Tube, Socket Cap Bolts, Self Tapper Screw, Instructions, and Forge Keyring and Sticker.
Progressive Parts offers fitting of the Forge Motorsport Blow Off Valve at our performance workshop. Upgrade your Mini with this reliable and high-performance valve for improved boost control and overall engine performance.
