MACH 2 - THE SIMPLE & ESSENTIAL MOD FOR 30% QUICKER BOOST
Utilising Proven TMS Technology To Ensure Dependable Boost Holding And Optimum Throttle Response. If you don't need the patented venting bias adjustment feature of the Respons or Deceptor Pro, the Mach 2 is the answer. 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).
Recirculation model for direct factory replacement for performance without the noise
Atmosphere venting kits to convert the recirculating valve if you want noise with your performance
Like the Respons and Deceptor Pro II, the Mach 2 is available in a range of 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) and add on kits are also available to convert to 100% atmosphere venting. Use the recirc model for direct factory replacement when you want the performance WITHOUT the noise! Add the conversion kit when you want some noise with your performance!
Factory bypass valves have two main shortcomings: one is that they are typically designed to blow open above a certain boost pressure to protect the engine, and the other is they are not optimised for throttle response. The Mach 2 solves all of these issues. It 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.
The Mach 2 can be converted to atmosphere venting. In some cases by simply purchasing a single hose plug and leaving the outlet open to atmosphere, or by using an Atmosphere Conversion Kit available separately. Optionally, for louder venting sound you can replace the outlet with a standard trumpet (6110) or a whistling trumpet (5702).
Vehicle Fitment:
Note: When installing a GFB valve, it must be installed in the OPPOSITE orientation to the factory plastic Bosch valve - i.e. air must enter the GFB valve at the bottom, and dump through the sides.
