Description

Forge Motorsport Dump Valves dump the charge-air into 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.

When accelerating the turbocharger produces compressed air which supplies the engine. When you lift off the accelerator the throttle butterfly closes and the boost has no escape route, so it backs up through the intercooler and causes back pressure, preventing the turbo from spinning, also known as compression stall. By installing a dump valve, every time you release the throttle excess boost pressure will be released creating a significant reduction in turbo 'lag' contributing towards faster pick up between gear changes.

Single Piston vs Twin Piston
The difference between a single piston & twin piston dump valve is that unlike single piston valve, a twin piston dump valves use counter balanced springs as well as dual pistons to prevent the valve from leaking air into the intake system at idle.

Made from billet aluminium.

Available in Black or Polished Alloy.

25mm flange size.

Forge Motorsport Atmospheric Dump Valve includes:

  • 1x Forge Motorsport Dump Valve
  • 1x Flange Adaptor (25mm diameter)
  • 1x Instruction Booklet

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

Uprated Forge Motorsport valve springs available separately.
