What should a Greddy type S sound like?

[scheat23]

Hey guys, what's up? Well, I've had my car for about 3 weeks now so here's a newb question. It is a 91 Talon TSI with K&N cone filter, and a greddy type s bov running about 11psi. Anyways...just today I decided to hook up the lower nipple to the vac line coming from the turbo. I also adjusted the spring hopefully correctly. Right now, under full boost I get a loud whoosh sound, but under low boost or part boost I get more of a light whoosh with a slight wistle. I'm just wondering if that sounds close to what it should sound like. I'm not getting any compressor surge or anything like that so I think it's correct but I just wanted a few opinions on it. I do have it venting to the atmosphere, and I have about 9 threads on the screw. I searched the forums and set it the best way I could following a few threads. Any help would be appreciated as this is my first turbocharged car. Thanks.

If this sound is made after lettign off the gas your good. As long as at half throttle, it is not letting air out it is most likely adjusted correctly.

i think i know what ur talking about mine was doing the same thing i had mine to tight u half to unscrew it almost all the way......best way to check put ur hand infront of the bov and see if there is air comming out when u let off if not loosen it up mine sounds like a whistle when i let off ....
