GFB Mach 2 Plumb Back to Atmosphere Vent Conversion Kit – Suits T9107/T9125

Application: Suits T9107/T9125
Part Type: Mach 2 Plumb Back to Atmosphere Vent Conversion Kit

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.

Kit Contents

• Trumpet outlet — replaces the hose outlet for a louder atmosphere sound (not required for function)
• Firmer spring, part #6115 — for engines where the stock spring can't hold the piston closed at idle
• 25mm hose plug — blocks off the recirculation hose outlet

Vehicle Fitment

• Suits T9107/T9125

Please confirm your Mach 2 valve part number before ordering.
