The VTA is a performance blow-off valve solution for Focus MK4 ST vehicles with an electronic factory diverter valve.   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 VTA shares the successful DV+ design philosophy: “Keep what works, replace what doesn’t” This means we retain ECU control and the solenoid from the factory diverter to ensure the fastest possible response time, without the added and unnecessary cost of replacing the solenoid like some brands do. The weak part of the factory diverter has always been the plastic valve mechanism – this is the part we replace. 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 modulation Improved boost holding ability Atmosphere venting for blow-off sound Retains ECU control 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 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?

TECHNICAL DATA Despite the AMG four’s high boost levels, these vehicles do not have a bypass valve fitted from the factory. This is likely because the plastic valves typically found in OEM setups would not be capable of handling the A45’s 26PSI of boost without failing prematurely. As a result, the AMG 45 models suffer from a significant amount of compressor surge. Compressor surge, combined with the A45’s high boost pressures, equals a recipe for disaster for the bearings inside the turbocharger. Enter Turbosmart’s Kompact Shortie Blow-Off Valve for the A45, CLA45 and GLA45 AMG. This high performance billet aluminium valve bolts straight onto the the compressor cover of the AMG’s turbocharger. With both Dual Port and Plumb Back variants available, owners can choose between the classic blow-off valve sound afforded by the Dual Port’s 50-50 split between recirculating and vent-to-atmosphere operation, or the quieter and OEM-like operation of the Plumb Back. Both variants dramatically reduce the compressor surge experienced by the A45 in standard form. The Shortie’s billet construction and high performance piston design, which eliminates the need for an O-ring to seal the body of the blow-off valve against the piston due to extremely fine machining tolerances, means the valve has no problem coping with the boost pressures produced by the AMG’s turbo, ensuring no leaks and extreme durability – even if you decide to turn the boost up. The VR03 Kompact Shortie Kit for the A45, CLA45 and GLA45 AMG includes a Boost Reference Adapter that allows the blow-off valve to respond to engine vacuum instantly, providing a greater level of control compared to electronically operated valves. This is possible by allowing the valve to access a manifold pressure reference in the AMG’s otherwise closed system – all without any destructive methods, such as tapping into the intake manifold. The Boost Reference Adapter offers two pressure ports, allowing you to run a second manifold pressure operated accessory, such as a boost gauge.

HOWEVER, VENTING TO ATMOSPHERE GIVES IT THE SIGNATURE BLOW-OFF SOUND, WHILST THE DV+ KEEPS THINGS QUIET. COMPETITORS' PRODUCTS FOR THE SAME VEHICLES THAT MAKE SOUND (I.E. BOV "SPACERS") TYPICALLY RETAIN THE PERFORMANCE DEFICIENCIES OF THE FACTORY DIVERTER VALVE, DELETE THE ECU CONTROL, OR REQUIRE FREQUENT MAINTENANCE AND REBUILDS. THE VTA ON THE OTHER HAND IS THE COMPLETE PACKAGE - PERFORMANCE, FIT, RELIABILITY, AND SOUND! Like the DV+, GFB’s VTA range of BOVs utilise GFB’s 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. Each valve in the VTA range is designed specifically for the applications we list them for, ensuring the best fit and performance. Most of the VTA range are designed for use on cars with solenoid type factory diverter valves, and in those cases the VTA kit will retain the solenoid and ECU control. Like the DV+ though, it replaces the weak factory valve internals to ensure strength and reliability, especially in high boost applications. Other versions of the VTA are designed for use on cars that do not have any kind of factory fitted diverter valve. Vehicle manufacturers have deleted the troublesome solenoid type diverter valve from some of the newer models, but this leads to turbo compressor surge which can be taxing on the turbo in the long run. The VTA valves for these cars are designed to re-introduce the function of a diverter/blow-off valve to help protect the turbo in the long term and provide a blow-off sound.
