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 factory diverter valve found on these cars has two distinct issues reliability, and performance. Oh yeah, it also doesn’t make any noise here’s how the vta addresses these problems. Reliability there are two ways in which the factory diverter valve can fail the un-reinforced rubber diaphragm can rupture, and the metal valve stem that slides in the plastic cap can stick. In both cases, there is a risk to the turbocharger, as the ecu will attempt to compensate for a boost leak by increasing the wastegate duty cycle, which increases the turbo rpm significantly. The vta features cnc machined billet components that last a lifetime and cannot be damaged by high boost pressures or the associated increased charge temperatures. Performance the factory diverter valve typically operates in only two states either fully open, or fully closed. When it opens at low boost, or during a partial throttle lift mid-corner, it causes increased lag and a noticeably non-linear boost transition, which is noticeable as a distinct step down in power as you roll off the throttle and the valve opens. The vta however allows the piston to o...
