Forge Fast Road Dump Valve
Made from billet aluminium, this atmospheric diverter valve dumps the charge-air to atmosphere creating the ‘whoosh’ sound commonly associated with rally cars when the throttle is lifted. This increases both throttle response and higher clamping load to maintain boost pressure more reliably. This product is suitable for all cars without an air flow meter.
All Forge single-piston and diaphragm atmospheric valves have been designed with the intent of venting 100% of the residual charge air remaining in your forced induction system to the atmosphere at throttle lift.
Owen Developments and Forge Motorsport cannot assume any responsibility for any adverse effects resulting from the installation of this valve onto a vehicle whose engine management system, whether factory or aftermarket, is not capable of compensating for the loss of metered air through a vent-to-atmosphere valve such as this.
