Blitz Venturi Drive Super Sound Blow Off Valve
Introducing the new "Venturi Drive Super Sound Blow Off Valve"
The all 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
There is an alternative hard spring for Boost pressures above 1.2bar and also a soft
spring available for very low Boost
applications. (please see DV Spares)
They are also tension adjustable.
All dump valve kits come with a comprehensive fitting kit tailor made to
fit your vehicle.
