Slowxr6t Member 563 Member For: 6y 30d Location: New zealand Posted 17/12/18 03:30 AM Share Posted 17/12/18 03:30 AM I think the stock blow off valves are fitted back to front because they are fitted with the piston side on the turbo intake side and not on the just before the throttle body side. What do you guys think about it? Link to comment Share on other sites More sharing options...

They actually seal better than most aftermarket valves. Link to comment Share on other sites More sharing options...
Slowxr6t Member 563 Member For: 6y 30d Location: New zealand Posted 17/12/18 07:39 AM Author Share Posted 17/12/18 07:39 AM I wonder why they fit them how they do? They are just relying on vacuum to pull piston off the seat a bit to pass some air, seems really dumb. I couldn't hear the stock bov doing any whoosh sound at all, then I put on a turbosmart kompact plumback on the correct way and I can hear it a little bit. I'm wondering if the stock bov does anything at all, which is a bit concerning if it could be causing compressor slow down. I think the way the aftermarket ones are plumbed vent easier, at least I know mine does. I had to really get on it and then back off real quick to get the stock one to vent. Aftermarket one vents with way less effort. Link to comment Share on other sites More sharing options...

I put my Kompact on backwards initially as I copied the factory orientation.Factory definitely works - if it didn't you would hear compressor surge. Remember too that the factory one is designed to be ultra quiet. My Kompact Dual Port makes much more noise than the factory BOV, even when set to full recirc (like it always is).

Sounds particularly stupid in an FG where it goes off after only light throttle. 1 Link to comment Share on other sites More sharing options...
