Mini Cooper S / JCW F6X Forge Motorsport E-DV Atmospheric Dump Valve

Upgrade Your Mini Cooper S / JCW F6X With The Forge Motorsport E-DV Atmospheric Dump Valve. Improved Sound. Enhanced Response. Plug & Play.

The Forge Motorsport Atmospheric Dump Valve (E-DV) is a premium, British-designed upgrade that replaces the restrictive OEM diverter valve on the turbocharged Mini F66 models with a high-performance alternative engineered for stronger throttle response and enhanced reliability. Constructed from certified aerospace-grade aluminium and backed by a lifetime warranty, this valve delivers quicker response times and frustration-free operation without risking engine management warnings.

Unlike traditional vacuum-controlled blow-off valves, the E-DV is an electronic diverter valve solution that requires no additional solenoids, vacuum plumbing, or complicated wiring. It offers plug-and-play installation with a 360° rotatable inlet for flexible fitment, making it ideal for both track-oriented cars and daily-driven tuned builds.

Whether you’re looking to eliminate compressor surge, improve throttle response, or upgrade the behaviour of your turbo system with a robust and serviceable valve, this Forge E-DV delivers a blend of performance, polish, and durability from one of the UK’s most respected motorsport component manufacturers.
