  • He doesn't have one, that sound is the compressor surging like crazy, not good

  • You can hear the BOV at 0:36 of the video. The wastegate makes the loud sound off throttle, open to air. Tial btw

see all

  • damn how many times i tell u all . this is not realli a surge . surge is more like a wind sound . bleh .

  • 10psi only! Boost that 40 more!

  • dont say there isnt a bov, you can see it hanging off the ic pipe clear as day. it is a tial and that is the bov you hear, most likely too tight a spring for the small amount of boost he is running.

  • damn sick surge

  • skippy is right, its neither a BOV or the wastegate. its compressor surge. the turbo is not in its efficiency range with such low boost, and its not even in its RPM sweet spot, you can hear the motor wanting to rev higher(getting into its powerband)

  • thats no bov noob not a damn wastegate the turbo spinning backwards

  • but it doesn't sound like it relieved any air when the throttle was let off. that sound at 0:36 was way after the throttle was let off. but its hard to tell anything from a video though:P

  • sorry to bother,what blow off valve do you have?
