Dump Valves / Blow Off Valves

GFB T9358 DV+ (Suits Mercedes, Ford and Volvo)


European manufacturers are pushing their engines to the limit. Get a DV to match.GFB's DV+ diverter valve range offers a direct-fit performance solution for the weak factory diverter valves used on many modern vehicles. By retaining the factory ECU control and recirculating the vented air, the DV+ is a purely performance-orientated product.GFBs DV+ design solves the longevity and boost leaking issues that are common with factory diverter valves, and also changes the operation method to pilot actuation to ensure better performance on stock or modified engines.Furthermore, these benefits wont cost you the Earth! Rather than throwing the entire factory diverter valve system in the bin (like other manufacturers solutions), the DV+ keeps what works and replaces what doesnt. It retains the factory solenoid and ECU control to ensure simple installation and reliable operation.10% faster opening, 50% faster closing than the factory diverterRetains the factory solenoid for seamless integrationReplaces plastic valve parts with metal for reliability and strength on stock or modified enginesDirect-fit replacement with GFBs TMS benefitsExclusive pilot-actuated valve mechanism for rapid response at high boostClick for fitting instructions

GFB T9458 VTA T9458 DV+ Performance, blow off valve sound!


The VTA is a performance blow-off valve solution for Mercedes vehicles with an electronic factory diverter valve.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 VTA shares the successful DV+ design philosophy:Keep what works, replace what doesntThis 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 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. 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 thats it. All the inherent performance and reliability issues you get with the factory diverter valve remain, because a spacer doesnt 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 theres 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?
