VTA

Like the DV+, GFBs VTA range of BOVs utilise GFBs proven TMS Technology to ensure rapid boost recovery on gearshift and optimum throttle response, as well as superior boost holding. However, where the DV+ and the VTA range differ is what they do with the vented air. VTA BOVs vent to atmosphere to make the signature turbo blow-off sound, where the DV+ recirculates the air to keep it quiet.

If you want sound with your performance (or performance with your sound!), GFBs VTA delivers just that!

The VTA features CNC machined billet components that last a lifetime, and we also change the valve operation method for better performance. The factory diverter valve can only operate in two states open, or closed. When it opens fully at low boost, or during a partial throttle lift mid-corner, it causes increased lag and a noticeably non-linear boost transition.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.It is this design philosophy that makes the VTA not only the best performing blow off valve solution, but also the best value on the market.Key features:TMS Technology for faster boost recovery on gearshift and during throttle modulationImproved boost holding abilityAtmosphere venting for blow-off soundRetains ECU controlSimple, direct bolt-on kits include everything you need to installManufactured in Australia in accordance with ISO 9001VTA or DV+?Depends if you want sound or not.

If you want sound with your performance (or performance with your sound!), GFBs 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 doesnt make any noise!Heres 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.

GFB VTA for late-model Audi,VW, Skoda, and SEAT 1.2 and 1.4TSI models

GFB

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.
