Description
The VTA is a performance blow-off valve solution for Audi,
VW, Skoda and SEAT vehicles with an electronic factory diverter valve.
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 fuelling issues.
The VTA clips directly into the turbo’s charge piping, replacing a short plastic joiner with a billet CNC machined section onto which the VTA mounts. The kit also includes a boost tee and vacuum hose that clips onto one of the manifold vacuum ports to source a vacuum signal for the VTA valve. This boost tee has a second port that can be used to connect a boost gauge (not included), or plugged off if not required. The whole kit can be fitted in minutes with no tools.
VTA or DV+?
Depends if you want sound or not. Both valves are constructed with
the same quality materials and valve mechanism, and both offer the same
performance and reliability benefits. However, the VTA vents to
atmosphere for sound whilst the DV+ recirculates the air to keep it
quiet.
Why choose a VTA over a “BOV spacer”?
“BOV spacers” are cheap and they make sound. But that’s it. All the
inherent performance and reliability issues you get with the factory
diverter valve remain, because a spacer doesn’t change the diverter
valve in any way. The VTA improves the operation of the diverter valve
for sound AND performance.
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?
