GFB Mach 2 Direct Fitment Diverter Valve

The Mach 2 Diverter Valve from Go-Fast Bits is designed to offer improved performance and throttle response on turbocharged engines.GFB have developed their valves using what they call "Turbo Management System" or "TMS" technology to ensure that the turbo can quickly build pressure and hold pressure while you're on part throttle.This tends to mean the turbo spools down relatively quickly and pressure has to build back up from zero.Unlike factory valves which are often at least partially open at all times except when you're at wide open throttle, GFB's TMS valves are designed to maintain at least some pressure in the intercooler under these circumstances meaning that when you get back on the throttle the turbo builds back up to full boost very quicklyUnder test conditions GFB have achieved a 30% quicker return to full boost.GFB have achieved all this with clever mechanical design and spring tuning.The Mach 2 valve is also designed to hold boost without opening. Most factory valves are designed to start opening even while you're on boost. This ensures no loss of power.The Mach 2 valve is set-up to operate as a recirculating valve by default but can be adapted to function as an atmospheric valve with an adapter kit.
