Some of the noise that is heard in superchargers I think comes from boost being partially controllered by an early opening of the blow of valve (if so equiped, mostly an aftermarket design). That was my understanding of how some aftermarket kits work although I might be wrong. If I am completly off just disreguard my misinformed nature and re-educate me. Otherwise look into the blow off a.k.a. by pass value. That is a source of much noise on mine because I have it vented to the atmosphere and when I have the throttle only slightly down and the turbo is in vacume it makes a "hissssss" not a "reeeee." That is all I got.
