Overview

The Go Fast Bits T9211 is a hybrid dual outlet blow-off valve designed to offer three configurations: full recirculation, full atmosphere, or 50/50 venting.
Show original supplier description
The Go Fast Bits T9211 Hybrid Dual Outlet Valve represents a return of the world's first dual-port blow-off valve, originally invented in 1998. This revolutionary design features staged venting outlets, allowing the recirc port to open before the atmosphere port. This staging helps prevent stalling and backfiring on vehicles equipped with a MAF sensor, while still delivering the desired blow-off sound when the car is driven harder.
Vehicle Symptoms
  • compressor surge / fluttering under part throttle
  • stalling when coming to a stop after hard boost
  • hissing air leak sound during gear changes
  • lag or hesitation between shifts
  • want louder turbo blow-off sound
