The VTA serves as a performance blow-off valve solution designed for Audi, VW, Skoda, and SEAT vehicles equipped with an electronic factory diverter valve. GFB's VTA provides a compelling combination of sound and performance enhancements, delivering an aggressive blow-off sound, improved throttle response, enhanced boost recovery, and superior boost holding capabilities, even under extreme conditions.
Incorporating GFB's successful DV+ design philosophy, the VTA adheres to the principle of "Keep what works, replace what doesn't." This means retaining ECU control and the factory solenoid to ensure rapid response times, without incurring the additional and unnecessary cost of solenoid replacement, as some other brands do.
The weak link in the factory diverter has always been the plastic valve mechanism, and this is precisely what the VTA addresses. It features CNC machined billet components known for their lifetime durability, coupled with a modified valve operation method for enhanced performance. Unlike the factory diverter valve, which operates in only two states (open or closed), the VTA utilizes GFB's pioneering "pilot operation" approach. This repurposes the factory solenoid to control the pressure behind the piston rather than the piston itself, resulting in a shorter solenoid stroke, faster response time, increased actuation force, and most importantly, progressive piston movement in response to varying boost pressure levels. This smoother boost transition minimizes lag, a common issue associated with the factory diverter valve.
This design philosophy positions the VTA as not only the best-performing blow-off valve solution but also the most cost-effective option on the market.
Key Features:
- TMS Technology for expedited boost recovery during gearshifts and throttle modulation.
- Improved boost holding capacity.
- Atmosphere venting for distinctive blow-off sound.
- Retains ECU control.
- Simple, direct bolt-on kits encompassing all necessary installation components.
- Manufactured in Australia in accordance with ISO 9001 standards.
Choosing Between VTA and DV+:
The choice between VTA and DV+ depends on the preference for sound. Both valves share the same quality materials and valve mechanism, offering equivalent performance and reliability advantages. However, the VTA vents to the atmosphere for sound, whereas the DV+ recirculates the air to maintain a quieter operation.
Why Opt for a VTA Over a BOV Spacer?
BOV spacers may produce sound at a low cost, but they do not address the inherent performance and reliability issues associated with the factory diverter valve. The VTA not only offers sound but also improves the operation of the diverter valve for enhanced performance.
Why Choose a VTA Over a Kit That Includes a Solenoid?
There is no performance advantage in replacing the factory solenoid; it only results in a significantly higher cost. Given that a VTA with the factory solenoid can open within a fraction of a second, there is no need to pay more than necessary.
