What do people say about GFB DV+ Blow Off Valves?
"...it’s rather brilliant"
"eliminates most of the factory fragile plastic parts...to improve reliability"
"...the improvement in throttle response is immediately perceptible"
GFB T9454 DV+ VTA Blow Off Valve
Improved performance whilst maintaining benefits of factory valves
Go Fast Bits T9454 DV+ VTA is designed to upgrade stock dump valves by replacing weak plastic parts with indestructible metal.
The plastic valve mechanism is where factory fitted blow off valves tend to crack at higher boost pressure, whilst GFB's metal valve mechanism can handle as much boost as you can offer.
The DV+ maintains the factory solenoid but the tolerance of the added metal offers a much sharper throttle response and improved fast valve actuation.
The GFB DV+ actuation system is unique, as the solenoid controls the air pressure that is used to open and close the piston, the DV+ will open and close without exceeding the solenoid's capability.
Manufactured to ISO 9001 standards, the GFB DV+ recirc valves do not need their spring tightening to run a higher boost.
The DV+ diverter valve has equal pressure on the top and bottom which will cancel each other out, meaning the valve will stay shut regardless of what boost pressure is ran.
GFB DV+ VTA Blow Off Valve (T9454) vents to atmosphere for sound whilst it can resolve boost leaking issues that occur with some factory diverter valves that crack open at high boost, to protect the engine from boost spikes.
Full included instructions are simple to follow for easy installation.
