Welcome to our listing for this BRAND NEW Twin Piston Dump Valve (fmdv004) and fitting kit (FMFK019)
Ford Escort RS Turbo Dump / Blow Off Valve complete with Fitting Kit
Made from billet aluminium, this atmospheric diverter valve dumps the charge-air to atmosphere creating the "Whoosh" sound when the throttle is lifted. This increases both quicker throttle response and higher clamping load to maintain boost pressure more reliably.
Unlike single piston or diaphragm diverter valves, this uses counter balanced springs and dual pistons to prevent the valve from leaking air into the intake system at idle. This prevents our diverter valves suffering any of the failures associated with single piston and diaphragm type diverter valves.
