Blow Off Valve Sound
When I switch gears, and once I get into the next gear, the blow off valve sounds gets cut off. Is that normal? In videoclips, I hear the full sound of the blow off valve. With mine, when I shift, you hear the blow off valve but once I get into the next gear, it goes away. So if I shift quick, you only hear it for half a second or so.

Re: Blow Off Valve Sound (Autobot_Killer)
I have a weird problem with my bov too. When I shift it goes FFF FFF FFFF FFF like a rapping sound. Is this a problem? I loosened the spring but it seems to do the same thing.

Your bov is not reacting fast enough, and it is causing a slight compressor surge. That is what the ff ff f f f f f sound is. It's not very bad, because it is only really minor, but over time it can affect your seals.

the turbo seals are at risk, and after awhile compressor surge will give the shaft of the turbo alot of play. just adjust the BOV. It should have a screw of some sort on it, just loosen it some.

For you guys getting the compressor surge or massive fluttering.
Try using a better vacuum source. I know a lot of people like to tee the hell out things. The best thing to do is tap some barb fittings into your intake manifold and use those.
Or get a good vacuum distribution box and hook it up between the brake booster and the intake manifold.
