Go Fast Bits VTA BOV (16-18 Focus RS)

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.

The factory diverter valve found on these cars has two distinct issues – reliability, and performance. Oh yeah, it also doesn’t make any noise! Here’s how the VTA addresses these problems.

Go Fast Bits "GFB" is a wholly Australian owned company started in 1997, manufacturing an exemplary range of innovative and high quality automotive products that give your vehicle the performance, sound, and looks you desire.

Our proudly Australian-made products are meticulously designed, tested, and crafted from the highest-grade materials in our own state-of-the-art CNC manufacturing facility. Keeping the design and production processes in-house affords us total quality control of our products from start to finish. Our philosophy at GFB is to produce exceptional automotive products that are built with the same precision, machining quality, and reliability that is the foundation of our reputation.

The VTA is a performance blow-off valve solution for the Ford Focus RS.

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.

The factory diverter valve found on these cars has two distinct issues – reliability, and performance. Oh yeah, it also doesn’t make any noise! Here’s how the VTA addresses these problems.

 

Reliability
There are two ways in which the factory diverter valve can fail; the un-reinforced rubber diaphragm can rupture, and the metal valve stem that slides in the plastic cap can stick. In both cases, there is a risk to the turbocharger, as the ECU will attempt to compensate for a boost leak by increasing the wastegate duty cycle, which increases the turbo RPM significantly.

The VTA features CNC machined billet components that last a lifetime and cannot be damaged by high boost pressures or the associated increased charge temperatures.


Performance

The factory diverter valve typically operates in only two states – either fully open, or fully closed. When it opens at low boost, or during a partial throttle lift mid-corner, it causes increased lag and a noticeably non-linear boost transition, which is noticeable as a distinct “step” down in power as you roll off the throttle and the valve opens.

The VTA however allows the piston to open and close progressively in response to the amount of boost pressure present, so it only vents enough air to prevent compressor surge (the primary purpose of a diverter or blow off valve). This helps to smooth out boost transitions, making the throttle response more linear and predictable, and also minimizes lag introduced by the factory diverter valve.

 

Sound
The VTA, as its name suggests, vents the air to atmosphere for maximum “whoosh” noise when you lift off the throttle. On the Focus RS, there is no MAF sensor and hence no drivability or fuelling issues when venting to atmosphere.

 

Key Features

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

 

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 factory diverter components or operation method in any way. The VTA improves the operation of the factory diverter valve for sound AND performance.
