Review on 🚀 Turbosmart TS-0203-1209 Kompact Plumb Back Blow Off Valve for Mazda/Subaru - Black, Enhanced SEO by Bernard Her

Bought this for my 09 WRX after reading decent reviews and because it is one of the cheapest recirculation valves which is obviously not a part. Well, this one is not a winner. I swapped out the Forge recirculator, thinking it would be less sensitive and a little quieter. I was right about both because it rarely worked on any build other than WOT, and when it did you could hardly tell. I think it's good for the factory noise level. The bad news is that you can easily hear the turbine chatter as the pressure pushes against the blades. I'm going back to Forge and unfortunately can't send it back to Revain, so I've got an interesting paperweight now. BTW, yes I know you can get different nibs but for $23 each without them. I would first recommend going without that and opting for an adjustable block or a block with the pressure adjustment parts already included in the box.
