Go Fast Bits DV+ Blow Off Valve
used on many European vehicles.
The solenoid coil itself from the factory-fitted valve is great (the ECU opens it faster than
any pneumatic valve so why replace it?), but the weak point however is the valve
mechanism itself. So GFB’s DV+ solves this problem by replacing just the valve parts with
an anodised billet aluminium housing fitted with a brass piston machined to exacting
The end result is sharper throttle response, lightning-fast valve actuation, and it will
hold as much boost as you can throw at it. Read all about the DV+ story on the
Other manufacturers’ products involve replacing the entire system with a traditional
pneumatic valve, requiring long vacuum hose runs, additional parts for tapping into the
intake manifold vacuum, plus either a different solenoid valve to actuate the pneumatic
valve or a ballast resistor to plug into the OE wiring loom. All these additional items result
in a product that is slower, less responsive, more expensive and takes much longer to
GFB’s DV+ solution on the other hand is more responsive, less expensive, easier to
install, and doesn’t cause compressor surge/turbo flutter. Oh, and it doesn’t require
different springs or frequent re-builds.
