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?

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.

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.

The new DV+ GFB’S DV+ SOLUTION COULDN’T BE SIMPLER - KEEP WHAT WORKS AND REPLACE WHAT DOESN’T. Uses factory solenoid coil for seamless integration Replaces plastic valve parts with metal for reliability and strength on chipped engines Direct-fit replacement with GFB’s TMS benefits Exclusive “pilot-actuated” valve mechanism for rapid response at high boost GFB expands the DV+ range with a direct-fit solution for the weak factory diverter valve used on many European vehicles. The solenoid coil itself from the factory-fitted valve is great- the ECU opens it faster than any pneumatic valve so why replace it? The weak point however, is the valve mechanism itself. GFB’s DV+ solves this problem by replacing the valve parts with an anodised billet aluminium housing, fitted with a brass piston machined to exacting tolerances. The end result is sharper throttle response, lightning-fast valve actuation, and it will hold as much boost as you can throw at it. Read all about the DV+ story below. Other manufacturers’ products involve replacing the entire system with a traditional pneumatic valve. This approach requires long vacuum hose runs, additional parts for tapping into the intake manifold vacuum, plus a different solenoid valve to actuate the pneumatic valve, or a ballast resistor to plug into the OE wiring loom. All these additional items result in a product that is slower, less responsive, more expensive and takes much longer to install. GFB’s DV+ solution on the other hand is more responsive, less expensive, easier to install, and doesn’t cause compressor surge/ turbo flutter. Oh, and it doesn’t require different springs or frequent re-builds either. GET BETTER PERFORMANCE, FASTER BOOST RECOVERY AND DON’T PAY FOR WHAT YOU DON’T NEED! The DV+ story: Better performance - more reliable Many late-model European cars use ECU controlled solenoid-type diverter valves. This is a good concept because the valve can react very quickly and it only opens when it needs to. However, there are some problems with these valves; The diaphragms are weak and known to rupture, especially if boost has been increased. Once this happens, the valve will no longer hold boost pressure.The plastic lip that surrounds the diaphragm is very thin and pieces can break off, potentially ending up going through the turbo. Additionally, the solenoid on the OE diverter is directly connected to the valve mechanism, which is not ideal because neither it nor the return spring are strong enough to open and close the valve reliably at high boost. With problems like this, you can see why other aftermarket manufacturers assume the best solution is to replace the factory diverter entirely, or change it to a purely pneumatic system. Unfortunately though, whilst their replacement kits might be stronger than the factory diverter, their slower response speed and lower flow do not justify the extra cost and complexity - more of a compromise than a solution. GFB has taken a different approach to deliver a complete solution that solves existing problems and improves performance, without compromise or a hefty price tag. The DV+ addresses the factory valve problems with a very simple and elegant solution. Keeping the factory solenoid, the DV+ retains all the benefits of the stock system. Also replacing the valve parts with indestructable metal components ensures strength and reliability, no matter how much boost you run. That’s not all; rather than using the solenoid to directly actuate the valve, we’ve introduced a unique “pilot-actuation” system. This means the solenoid only has to control airflow through a small passage that is then used to open and close the piston (rather than opening and closing the piston directly), so it doesn’t matter how much boost you push through it, the DV+ will open and close reliably without ever exceeding the solenoid’s capability. This feature also improves on the factory system by opening the valve progressively in response to boost pressure, so it only opens as much as required to get the job done (the factory valve simply opens and shuts, it cannot partially open if boost pressure is low), resulting in better throttle response. Unnecessary replacement kits are a compromise, not a solution
