so before i put in my gt28rs, bov was fine. after it sounds like hmmm like a rubber flutter nothing like its a greddy type s sound.
now before you guys ask did i adjust i did. me and my friend found problems with how the vacuum was being run so we fixed it as well. it made the sound before the fix and after it. when i rev the car in neutral is sounds almost normal but driving sounds like crap. im also driving out of tune and i have the boost way turned down due to stock injectors still.

if i missed any thing let me know! let me know

You said your boost is way turned down. Low boost = low noise.

its weird the noise is like rubber on rubber fluttering noise... olny when the car is driving but when i rev it has more of the greddy sound mixed in with the rubber sound..

nujabe · 05-09-2011, 02:26 PM

Do bovs have a rubber seal? I never opened one up but if they do, make sure urs is properly seated

How about a sound clip as "rubber sound" isn't exactly descriptive.

It is probably compressor surge. It sounds like a flutter I bet. Like pigeons!

Bigger turbo is pushing more air/pressure. So if you haven't readjusted your bov, that is more than likely it.

Should have just messaged me boyyyyyyyyyy

Where did you run the Vac line for the BOV?

Might not have enough vac to open.
