Bypass valve GFB, Volvo, Ford, Porsche, part nr. DV+ T9354

Go Fast Bits DV+ T9354 dumping valve. To replace the dump valve that is mounted on the compressor housing of different Volvo, Ford and Porsche models and Borg Warner turbochargers.

This GFB dump valve provides a sharper throttle response, faster recovery of the turbo pressure after switching and solves leaks in the original diaphragm dump valve.

One of the most common problems with dump valves mounted on the compressor housing is the rupture of the diaphragm. This is often the case with tuned cars, which collect a little more heat in the compressor housing. In addition, the operation of the standard valve is not aimed at the fastest response time or best throttle response. The diaphragm can only be fully closed or fully closed, where the GFB dump valve can also partially open, depending on the available pressure. When a dumping valve can only fully open and close, it often happens that too much pressure is ventilated, which can take time before the pressure is rebuilt and the throttle response feels worse.
