GFB Mach 2 T9100 TMS Recirculating Diverter Valve for Subaru Applications

Blow off sound not to your taste? Want something as “sleeper” as possible? 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.

The Mach 2 is available in a range of universal and bolt-on kits for most popular turbo models. 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, 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.
