you cant hear your turbo? weird. are you sure you are not over oiling? the only time i couldnt hear my turbos is when I tried that -4AN feed. over oiled the turbos. Went back to the -3AN and back to normal.
OP, the video looks fine. whatever you did fixed the problem
i've never used anything except a 3an line. Mine has always been quiet as can be. The only turbos ive ever heard noise from are the front mount setups like in the SRT-4 neons that have huge turbos right up in their grill. Interesting
I would assume with my built heads and headers i would have enough flow to move the turbo during a free rev.
