Product Description
Details

Blitz Venturi Driver Dump Valves create a unique super sound blow off noise and are designed to improve turbo response by quickly releasing the boost pressure before the turbo stalls.

The new ribbed body design dissipates heat more effectively and the venturi shaped funnel creates a sharp dynamic sound.

Aso features "Dual Drive" for maximum response which consists of a small port for low boost and a larger port for high boost.

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.

Made from die cast polished aluminium with a brass piston and rubber diaphragm.

The Blitz Venturi Drive dump valve comes with a factory tuned spring that can easily cope with boost pressures up to 1.2BAR.

Fully tension adjustable.

Optional 31mm diameter stainless steel weld-on flange.

Available in Chrome only.

Uprated Blitz valve springs are available in our "Forced Induction Accessories" section.
