Description

Dual Piston Blow Off/Dump ValveSuitable for most turbo cars with an Air Flow Meter. 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

Suitable for most turbo cars with an Air Flow Meter. 

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.

All Forge Motorsport Dual-Piston Atmospheric Valves have been designed and built with the intent of venting 100% of the residual charge air remaining in your forced induction system to the atmosphere at throttle lift. While we have incorporated many elements into the design of the Dual-Piston valves to aid in their compatibility with mass air-flow sensor equipped vehicles, we cannot always guarantee that each individual’s application will be compatible with a valve that vents the charge air into the atmosphere.

Forge Motorsport nor any of it’s Authorised Distributors can 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.

 

In The Box:
1 x FMDV004 Valve
1 x Forge Sticker

If you wish to tune this product to fit the needs of your engine, please see the spring tuning kits below.

The valve has a port size of 25mm

We recommend servicing your valve every 3 years, or 20,000 miles, whichever comes sooner

Worked great for the 4 months it lasted
Color: Green/Battery
I liked this can opener a lot when I first got it. It was easy to use, and it left smooth edges after opening the can. I also liked the fact the batteries were replaceable. However, after 4 months it stopped opening the cans. It just went around and around the edges. I tried replacing the batteries but it did not help. I plan to replace it with a different brand.
