BOV Fluttering?

[asshanson]

You have to plug the BOV return on the intake pipe otherwise you are letting in unmetered air. Even if you dont recirc the BOV you have to plug that hole in the intake.

Leave the lower port open, so that the diaphragm can move up and down freely. And you need to plug that open hole in the intake after the MAF.

That's all compressor surge. Where do you have the BOV vacuum hose hooked up? The BOV isn't even moving.

Is it an ebay bov?

yep...yep it is :( this is possibly a reason why also.

I really doubt it is compressor surge because if it was, i'm quite sure i can play with the compressor wheel but thankfully it isn't like that.

That is not compressor surge. Compressor surge only happens under load when the turbo is near peak efficiency. See Kevin's video.

Your BOV is fluttering, but it's nothing to worry about as long as it holds boost. You can screw down the bolt on top of the BOV to give it more tension and that will help prevent the fluttering and cause it to only be open or closed. To be honest, as long as the car runs fine, drives fine and the BOV doesn't leak then it can act however it wants.

It doesn't appear it is opening at all. You sure you vac reference is hooked up correctly.

doesn't having a non-opening BOV still put unnecessary stress on the turbo?
