Might be time for one of those stealth FX BOVs.

Any BOV you can buy would obviously be fitted on the output side of the turbo (I.E what is the point of a BOV for a section of intake that is constantly in vacuum?) The turbosmart ones come in a few different forms. You can buy a Kompact series dual port that vents both to atmosphere and also to your intake. In this case it would pipe straight into the locationo f the standard BOV. I believe they bolt straight on. If you bought the one that vents straight to atmosphere with no venting to intake then you would block off the return pipe to the intake with the provided cap as all your air would escape to atmosphere.Hope this helps mate. Also, I noticed the flutter too as soon as I hooked up the 2nd cold air intake. Sounds pretty cool I rekon! Sounds like its normal though.

I noticed that the stock BOV is on the back of the manifold. Does that mean the factory BOV is between the airbox and the turbo (I.e. the "wrong" side) rather than between the turbo output and the throttle body (after the intercooler).I noticed that the Turbosmart guys get you to block off the existing BOV plumbing and plumb theirs into the intake hose closest to the throttle body. I can't tell if that's because their BOV won't fit where the stock one goes, or if theirs is more efficient because it's on the side of the turbo where the BOV would be best located to reduce pressure on the turbine blades...I don't go into the details.I just give money to the "dynowog" and he makes my car go fast.305rwkw... Very Nice.. I like.... Link to comment https://www.fordxr6turbo.com/forum/topic/40576-my-stock-bf2-turbo-has-turbo-flutter/page/2/#findComment-608808 Share on other sites More sharing options...
