MACH 2: 100% Recirculating Diverter Valve

THE SIMPLE AND ESSENTIAL MOD FOR  QUICKER BOOST RESPONSE

Utilising Proven Tms Technology To Ensure Dependable Boost Holding And Optimum Throttle Response

Blow off sound not to your taste? Want something as “sleeper” as possible? Don’t want your partner to know you’ve stuck a turbo on the daily (again)? Then the GFB Mach 2 is the valve for you!

Using GFB’s TMS technology the Mach 2 can help return the engine to peak boost up to 30% faster than a factory diverter valve when shifting gears (more information below).

The Mach 2 is available in a range of universal and bolt-on kits for most popular turbo models. And when we say “bolt-on”, that’s exactly what we mean! No additional adaptors, parts or vehicle modifications are required – simply remove the factory bypass valve and replace it with the Mach 2 – it’s that simple!

The Mach 2 is configured as a 100% recirculating valve (i.e. bypass, plumb back) as a direct factory replacement, for when you want all the performance WITHOUT the noise!

Why replace the factory bypass valve? Better performance! Factory bypass valves typically have two main shortcomings – one is that they are often designed to blow open above a certain pressure to protect the engine (if you drive an EVO, take note and read this article!), and the other is they are not optimised for throttle response.

The Mach 2 solves both issues. With its pressure-balanced design, the Mach 2 can effectively hold unlimited boost (unlimited in that no turbo could ever produce enough pressure to damage it), and the TMS technology ensures maximum throttle response.
