Blitz Super-Sound Blow-Off Valve VD (Venturi Drive) BOV

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 supplied spring. 



They are also tension adjustable.
