GFB Mach 2 Plumb Back to Atmosphere Vent Conversion Kit - Suits T9107/T9125
GFB is well known among turbo and supercharger enthusiasts for building blow off valves that are both reliable and tuneable, and this Atmosphere Conversion Kit gives Mach 2 owners the option to switch from recirculating to atmosphere venting for that classic turbo sound without sacrificing piston control.
This listing covers the conversion kit suitable for the GFB Mach 2 T9107 and GFB Mach 2 T9125 blow off valves. It includes everything needed to safely vent to atmosphere while keeping the piston sealed at idle.
Note: the Mach 2 ships with a softer spring (part #6116) suited to recirculating setups or engines with idle vacuum of 18inHg or less. If the piston hovers open at idle even with preload maxed, install the firmer spring (part #6115) included in this kit to prevent stalling or backfiring.
Fitment and compatibility notes are provided in the tabs above. Please confirm your Mach 2 valve part number before ordering.
