GFB Mach2 Diverter Valve / Blow Off Valve – (Recirculating or Vented Available)
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).
All Valves come as a Recirculation model for direct factory replacement for performance without the noise.
Atmosphere venting kits are available for an extra cost 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 purchase & 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!
