GFB T9105 Mach 2 Diverter Valve with TMS Technology and Atmospheric Venting Option

The GFB Mach 2 T9105 is a high-performance diverter valve (BOV) designed to dramatically improve throttle response and boost recovery on turbocharged vehicles. Using GFB's patented TMS (Turbo Management System) technology, the Mach 2 can return the engine to peak boost up to 30% faster than factory diverter valves during gear changes, delivering sharper acceleration and reduced turbo lag.

Key Features:

• TMS technology for superior throttle response and faster boost recovery
• Two valves included in the kit for complete installation
• Direct bolt-on replacement for most popular turbo models - no additional adapters or modifications required
• Capable of holding unlimited boost pressure without risk of damage
• Configured as 100% recirculating (bypass/plumb-back) valve from factory
• Optional atmospheric venting conversion kit available for audible blow-off sound
• Can vent to atmosphere without engine stalling issues common with factory valves

Installation and Configuration:

The Mach 2 installs as a true bolt-on replacement - simply remove your factory bypass valve and install the Mach 2 in its place. No cutting, fabrication, or additional parts needed. The valve comes configured for 100% recirculation, making it ideal for those who want performance gains without additional noise. For enthusiasts who want the signature blow-off sound, conversion kits are available to switch to 100% atmospheric venting.

Performance Advantages:

Factory bypass valves are typically designed to open at a specific pressure threshold for engine protection and are not optimized for performance. The Mach 2 eliminates these limitations with a design that can handle virtually any boost level while maximizing throttle response through TMS technology. Unlike factory valves, the Mach 2 can safely vent to atmosphere without causing engine stalling or running issues.
