GFB T9481 VTA blow-off valve solution for for the late-model VW
In summary, if you know your GFB valves, this is the same as the T9451 VTA but with an integrated solenoid valve for a lower stack height and greater engine bay clearance.
If you want sound with your performance (or performance with your sound!), GFB’s T9481 VTA delivers!
By combining atmosphere venting with the proven performance benefits of our ground-breaking DV+, the VTA delivers an aggressive blow-off sound, improved throttle response, as well as superior boost holding and reliability.
With its low-profile integrated solenoid and compact design, installing the T9481 is a breeze. Just swap out your factory diverter valve with the VTA, and you’re good to go.
Reliable Boost Holding
Despite
some improvements in reliability by the latest generation of OEM
diverter valves, the performance trade-offs remain. There is no escaping
the fact that the moulded plastic valve mechanism of the OEM valve
cannot reliably seal boost pressure. The VTA’s CNC-machined aluminium
and brass valve components, combined with a Viton face seal ensure
reliable boost holding even up to 50psi.
Sharper Throttle Response, Faster Boost Recovery
OEM
electronic diverter valves are binary in operation – they’re either
open or shut. Your throttle, however, isn’t. When you make small
throttle adjustments, the binary operation of the factory diverter
results in abrupt changes in power delivery, which is the very
definition of poor throttle response. GFB’s patented “pilot actuation”
system allows the VTA’s piston to open and close progressively, thereby
smoothing the power delivery during throttle modulation, and ultimately
improving throttle response.
Unrivalled longevity, backed by our Lifetime Warranty
The
combination of precision manufacturing, attention to detail, and robust
materials means the VTA will last a lifetime. So does the warranty.
Why choose a VTA over a "BOV spacer"?
Whilst
“BOV spacers” might offer a cheap way to get a blow-off sound, they
fail to tackle the fundamental performance and reliability issues
associated with the OEM diverter valve - all they do is redirect the
vented air.
The VTA offers more than just sound. By replacing the OEM diverter valve you also get enhanced performance and reliability.
