GFB T9120 BOV Mach 2 TMS | Subaru WRX/STI 94-96 / Toyota Supra JZA80
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 â€“ simply remove the factory bypass valve and replace it with the Mach 2 â€“ 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 â€“ one is that they are typically designed to start opening above a certain 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.
