A popular choice of dumpvalve for the Nissan R35 GT-R is the Twin Venturi Drive Super Sound Blow Off Valve - Release Type. It is very unique in appearance and as always with Blitz, is a great quality component.
- New ribbed main body dissipates heat more effectively and the venturi shaped funnel creates a sharp dynamic sound.
- Venturi Drive dump valves also feature "Dual Drive" for maximum response, a small port for low boost and a larger port for high boost.
- The main purpose of the dump valves is to improve the response of the turbo by quickly releasing the boost pressure before the turbo stalls.
- They are made from die cast polished aluminium with a brass piston and a rubber diaphragm, meaning they can easily cope with boost pressures up to 1.2 bar with the supplied spring.
- There is an alternative hard spring for boost pressures above 1.2bar and also a soft spring available for very low boost applications.
- They are also tension adjustable.
- This kit comes with twin dump valves and includes everything needed to install onto your vehicle.
