What they gain in operational speed, they lose in throttle response. The VTA adapts the method of operation of the factory diverter system to give you the best of both worlds.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePilot Operation\u003c\/strong\u003e – the patented design of the VTA means the piston is not directly connected to the solenoid, so it can open and shut progressively. This operation method leads to improved throttle response and drivability, because the VTA is more “discerning” about how much air it vents when triggered by the ECU – it only vents the amount of air necessary to eliminate pressure spikes that cause compressor surge, where the factory diverter opens fully whether it needs to or not.\u003c\/p\u003e\n\u003cp\u003eWhen you close the throttle during spirited driving, the VTA opens to prevent compressor surge and protect the turbo. When the pressure has dropped sufficiently, the piston begins closing to preserve a small amount of boost in the intercooler for as long as possible. This helps the turbo return to peak boost faster when you re-open the throttle. We call this the Turbo Management System (TMS) benefit.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eLightning-fast operation\u003c\/strong\u003e – vehicle manufacturers use an electronic diverter valve because they respond faster than pneumatic valves. Well, the VTA is faster again! No other valve on the market comes close to matching the VTA opening and closing speeds.\u003c\/p\u003e\n\u003ch4\u003eHold my boost and watch this…\u003c\/h4\u003e\n\u003cp\u003eYour turbo works hard to create boost, so why make it work harder than it needs to? A GFB VTA ensures that all your hard-earned boost makes it to the engine.\u003c\/p\u003e\n\u003cp\u003eUnsurprisingly, the moulded plastic valve components in the factory electronic diverter valve don’t seal that well. A boost leak from the factory diverter valve will cause the ECU to drive the turbo harder to compensate for the loss, resulting in higher turbo RPM, more exhaust backpressure, and hotter compressor outlet temperatures. So even though your tune might still hit target boost, a diverter leak means the turbo is more stressed, and the engine makes less power.\u003c\/p\u003e\n\u003cp\u003eThe VTA replaces the factory diverter’s loose-fitting plastic valve with precision CNC machined metal components and a durable elastomer piston seal. Because the VTA design uses boost pressure to force the piston shut, it doesn’t matter how much boost you throw at it – a VTA won’t fail, leak, or blow open.\u003c\/p\u003e\n\u003ch4\u003eSpecific Product Information\u003c\/h4\u003e\u003ch4\u003eDescription\u003c\/h4\u003e\n\u003ch4\u003eVTA T9451 DV+ Performance, Blow Off Valve Sound!\u003c\/h4\u003e\n\u003cp\u003e\u003cem\u003e\u003cstrong\u003eWORLDWIDE PCT PATENTS PENDING\u003c\/strong\u003e\u003c\/em\u003e\u003c\/p\u003e\n\n\u003cem\u003e\u003cstrong\u003ePROTECTED BY CHINA UTILITY MODEL PATENTS; CN206054094U \u0026amp; 206129406\u003c\/strong\u003e\u003c\/em\u003e\n\n\u003cp\u003e\u003cstrong\u003eThe VTA is a performance blow-off valve solution for Audi, VW, Skoda and SEAT vehicles with an electronic factory diverter valve.\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eIf 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.\u003c\/p\u003e\n\u003cp\u003eThe VTA shares the successful DV+ design philosophy:\u003c\/p\u003e\n\u003cp\u003e“Keep what works, replace what doesn’t”\u003c\/p\u003e\n\u003cp\u003eThis 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.\u003c\/p\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\u003cp\u003eGFB 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.\u003c\/p\u003e\n\u003cp\u003eIt 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.\u003c\/p\u003e\n\u003cp\u003eKey features:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eTMS Technology for faster boost recovery on gearshift and during throttle modulation\u003c\/li\u003e\n\u003cli\u003eImproved boost holding ability\u003c\/li\u003e\n\u003cli\u003eAtmosphere venting for blow-off sound\u003c\/li\u003e\n\u003cli\u003eRetains ECU control\u003c\/li\u003e\n\u003cli\u003eSimple, direct bolt-on kits include everything you need to install\u003c\/li\u003e\n\u003cli\u003eManufactured in Australia in accordance with ISO 9001\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eVTA or DV+?\u003c\/p\u003e\n\u003cp\u003eDepends 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.\u003c\/p\u003e\n\u003cp\u003eWhy choose a VTA over a “BOV spacer”?\u003c\/p\u003e\n\u003cp\u003e“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.\u003c\/p\u003e\n\u003cp\u003eWhy choose a VTA over a kit that includes a solenoid?\u003c\/p\u003e\n\u003cp\u003eBecause there’s no performance benefit to replacing the factory solenoid, only a much higher price!
