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. \u003cbr\u003e\u003cbr\u003e\u003cstrong\u003ePilot Operation\u003c\/strong\u003e\u003cbr\u003eGo Fast Bits pioneered the use of pilot operation in the DV+ range, 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. \u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eDirect Bolt-On Kit\u003c\/strong\u003e\u003cbr\u003eAs you would expect from a Go Fast Bits product, the F150 VTA comes as a direct bolt-on kit. When we say bolt-on, that’s what we mean. Other products use brackets that don’t bolt up to the OEM diverter mount holes, meaning they are useless on aftermarket intercoolers, and because they have to supply two to cover all year models, the brackets are cheap and flimsy. Our bracket is powder coated stainless steel, and is designed to replicate the footprint of the OEM diverter valve mount. This means it fits all 2013-2020 models, AND aftermarket intercoolers. Not only that, the blanking plug is attached to the bracket so it plugs the recirc AND holds it securely in the engine bay.\u003cbr\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003ca style=\"color: #afafaf;\" href=\"https:\/\/stmtuned.com\/collections\/gbf-go-fast-bits-products\"\u003e\u003cbr\u003e\n\u003cdiv style=\"text-align: center;\"\u003e\u003cspan style=\"font-size: .8em;\"\u003e See more Go Fast Bits\u003c\/span\u003e\u003c\/div\u003e\n\u003c\/a\u003e","brand":"Go Fast Bits","offers":[{"title":"Default Title","offer_id":50560424411478,"sku":"GFB-T9464","price":280.39,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0817\/9531\/8102\/files\/gfb-vta-performance-blow-off-valve-gen2-ford-raptor-t9464.jpg?v=1749192704"},{"product_id":"gfb-diverter-valve-audi-s4-s5-rs4-rs5-t9380","title":"GFB Diverter Valve for Audi S4\/S5\/RS4\/RS5 (T9380)","description":"\u003cp\u003eUpgrade your Audi RS5 with the Go Fast Bits DV+ diverter valve for superior boost holding durability and throttle response.

Whilst the latest generation of OEM diverter valves have become more reliable, there is always a performance trade-off due to their operational method and plastic construction. \u003cbr\u003e\u003cbr\u003eWhen GFB engineers performed boost leak testing on the OEM diverter valve in a VW Mk8 Golf R, they found the leak was significantly larger than in earlier generations. \u003cbr\u003e\u003cbr\u003eThis excessive leaking is due to the emerging trend of manufacturers mounting diverter valves remotely on plastic piping rather than directly on the turbocharger. A plastic valve mechanism closing onto a plastic seat resulted in the largest OEM diverter valve leak we’ve seen yet at 28L\/min at 1 Bar of boost. \u003cbr\u003e\u003cbr\u003eEven with the Viton face seal (featured on all DV+ pistons), the plastic OEM seat face was found to be so uneven that it was impossible to achieve a reliable seal. The T9380 successfully addresses this issue by incorporating an integral piston seat machined into its body. This design ensures a proper seal, even on uneven plastic OEM seats. \u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eSharper throttle response, faster boost recovery after brief throttle lift\u003c\/strong\u003e \u003cbr\u003eFactory electronic diverter valves are binary in operation – they’re either open or shut.

Featuring GFB’s patented venting bias adjustment system, the Respons allows you to precisely control how much air vents from each of the two outlets.\u003cbr\u003e\u003cbr\u003eWhy is this so important? There are two key reasons:\u003cbr\u003e• Adjust how loud the blow-off sound is. Recirculate all of the air for silent factory operation, vent it all to atmosphere for maximum noise, or set it ANYWHERE in between to suit your preference.\u003cbr\u003e• Get a blow-off sound WITHOUT causing stalling, backfiring, or any other BOV-related issues, even on a car with a sensitive airflow meter (MAF).\u003cbr\u003e\u003cbr\u003eHold on, it gets better. The Respons isn't just a noise-maker.
