GFB Mach 2 Diverter Valve

The GFB Mach 2 Diverter Valve (also called a blow off valve, BOV, or bypass valve) is a direct-fit replacement for the factory diverter valve on turbocharged engines. It comes from Go Fast Bits (GFB). It supplies quicker boost recovery and sharper throttle response, and it keeps the stock, quiet operation. It is a simple upgrade for drivers who want the performance without a loud blow off sound.

Key Features:

• Single venting outlet, configured from the factory for full recirculation (plumb-back) operation
• Can be converted to atmospheric venting with a separate GFB atmosphere conversion kit
• GFB TMS technology, which can return the engine to peak boost up to 30% faster than a factory diverter valve when shifting gears
• Holds boost pressures of 100 psi or more, so it will not blow open under boost the way some factory valves can
• Direct bolt-on design. No adaptors, extra parts or vehicle modifications are needed. You remove the factory valve and install the Mach 2 in its place.
• Made in Australia in accordance with ISO 9001

The Mach 2 addresses two common shortcomings of factory bypass valves: they can open under high boost pressure, and they are not tuned for throttle response. It suits street-driven and performance builds that need dependable boost holding. Choose the variant that matches your application.
