FORGE MOTORSPORT UNIVERSAL TWIN PISTON DUMP VALVE FMDV004
Welcome to our listing for this BRAND NEW FMDV004 Twin Piston Dump Valve.
This auction is for a polished silver Forge Motorsport FMDV004 Dump Valve Which fits all Turbo cars.
Made from billet aluminium, this twin piston valve dumps the charge-air into the atmosphere creating the "Whoosh" sound most commonly associated with rally cars when the throttle is lifted. This increases both quicker throttle response and higher clamping load to maintain boost pressure more reliably.It uses twin springs as well to prevent air leaking back into the intake system when at idle.
