GFB Mach2 Diverter Valve / Blow Off Valve - Recirculating or Vented Available

NEW MACH 2: ENTRY LEVEL TMS

 

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 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 start opening above a certain pressure to protect the engine, and the other is they are not optimised for throttle response. Oh, and you can’t vent them to atmosphere without stalling your engine…
 
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. Oh, and you CAN vent with the atmo conversion to atmosphere without stalling your engine…

GFB Whistling Trumpet

 

The ability to change the sound of a blow-off valve is increasingly becoming an important issue with buyers, who want to sound different from everyone else.

 

GFB have released the Whistling Trumpet (part # 5701), which emitted a piercing screech when driving aggressively. Unfortunately for a number of GFB owners, the 5701 trumpet only worked with some valve types.

 

For the owners of all other types of GFB valves, GFB have now released the 5702 – a modified version of the Whistling Trumpet that is designed to work on low boost applications where the 5701 doesn’t cut it. 

 

The 5702 can be used in place of the standard trumpet on all GFB valves, and will make the whistling sound more readily than the 5701 (high boost and RPM is required to get the whistle from a 5701), and at a slightly higher pitch.  Like the 5701 however, it is necessary to run the valve so that all (or most) of the air vents through the trumpet – Respons valves will typically not generate the velocity required to whistle when set to 50/50 venting.
