T9430 Go Fast Bits GFB VTA DV+ PERFORMANCE, BLOW OFF VALVE SOUND

The Latest Addition To The VTA Range Is A Blow-Off Valve Designed Specifically For Late-Model Audi, VW, Skoda, And SEAT 1.2 And 1.4TSI Models.

These engines come from the factory with no diverter valve of any kind, which results in turbo compressor surge every time the throttle is closed after boosting.
The intake is acoustically tuned to suppress the fluttering sound of compressor surge, but it does not eliminate the effect of pressure pulses – that is what diverter and blow-off valves were originally designed to do.

The GFB VTA re-introduces a blow-off valve into the 1.2/1.4 TSI system, which eliminates compressor surge to protect the turbo, and delivers the signature blow-off “whoosh” when lifting off the throttle.
Because these engines do not run a MAF sensor, there is no chance of adverse drivability or fueling issues.

If you want sound with your performance (or performance with your sound!), GFB’s VTA delivers just that! By combining the proven performance benefits of our ground-breaking DV+ with atmosphere venting, the VTA delivers an aggressive blow-off sound, improved throttle response and boost recovery, as well as superior boost holding and reliability in extreme conditions.

GFB pioneered the use of “pilot operation” in the DV+, which works by re-purposing the factory solenoid to control the pressure behind the piston rather than the piston itself. This allows the solenoid stroke to be much shorter, speeding up the response time and increasing the actuation force. More importantly, it allows the piston to open and close progressively in response to the amount of boost pressure present, which smooths boost transitions and reduces the lag caused by the factory diverter valve.

Key features:

• TMS Technology for faster boost recovery on gearshift and during throttle modulation
• Improved boost holding ability
• Atmosphere venting for blow-off sound
• Retains ECU control
• Simple, direct bolt-on kits include everything you need to install
• Manufactured in Australia in accordance with ISO 9001

Why choose a VTA over a kit that includes a solenoid?

Because there’s no performance benefit to replacing the factory solenoid, only a much higher price! If a VTA with the factory solenoid can open in a couple of hundredths of a second, why pay more than you need to?
