Forge Single Piston Ram Dump Valve

An atmospheric dump/blow off valve suitable for all turbo cars without an air flow meter. Made from billet alloy and using a single piston this valve will run faultlessly without the need for attention and eliminates the longevity problems associated with the original diaphragm valves.

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.
