Turbosmart Smart Dual Port Atmospheric Dump Valves - Nissan GTR R35
The Turbosmart Smart Dual Port Dump Valve is an innovative Blow-Off Valve, combining advanced design with precision CNC machined billet components.
A direct fit replacement to the factory unit and is capable of handling anything from stock to heavily modified applications with upgraded turbochargers.
Features innovative new drive-by-wire friendly staging technology.
Smart Port Technology - The Smart Port is an innovative Blow-Off Valve, combining advanced design with precision CNC machined billet components. The valve works by using two staged ports and a one way valve on the trumpet outlet. This enables the Smart Port BOV to work like both a bypass AND vent to atmosphere valve in one, while also eliminating stalling and significantly reducing the chances of low speed compressor surge. In addition to this, the Smart Port’s unique lightweight piston is made from aerospace alloy with a military-spec coating, resulting in quicker valve response, better sealing and superior durability.

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.
