bump..can anyone figure out my whistling problem??

 

Try using a different vaccum line. That black box is a vaccum canister (it's all hollow inside) that may have something to do with it. Another reason may be that you have a BOV built for high boost applications, and you are not running very high boost with a Comptech (correct me if you aren't at stock boost). I have the Raptor by Turbonetics (1 step below Godzilla) and I have a little bit higher boost from the Vortech, but mine works just fine. He also shouldn't be getting any compressor surge (it's not a turbo) unless his belt is really loose.


What does it sound like? Godzillas are known for their loudness...

 

Try running a dedicated line to the bov. If it still whistles it could be an improperly set up bov(too little spring pressure) or a defective unit. Rember, it's supposed to vent at idle and cruising under no-load conditions.

 

Um that is normal. Your BOV works fine.

 

doesnt sound like your video though. in your in between shifts theres no whistling and when i shift in my car i hear whistling. i dont think you understand the noise i'm hearing.

when i'm cruising at around 70mph in 6th theres this high pitch whistle thats really annoying.

 

Is your bov used? Mine does that now because the seal is worn. Tighten the spring.
