This Turbosmart Race Port Dump Valves have been designed with competition applications in mind and has the ability to operate in systems up to and over 800bhp.
The Race Port now features a 52mm oversize inlet with 50mm piston making it the largest and highest flowing valve in the range.
Constructed using high quality billet alloy for consistent and accurate action.
The valve internals have been developed for durability with a silicone nomex diaphragm and billet piston ensuring a 'fit and forget' solution.
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.
52mm flange.
Available in Blue or Black
