    take the sc belt off, and drive it, see if the noise is still there,

    if you have a open cone air filter, you will hear the sc whine.

    could be the power steering pump or the trans pump, whining as well. so check both of those fluid levels as well.

    blower typically has a "bad bearing" sound if any of the bearings go, so no, it shouldnt whine.

    Check alternator and power steering fluid levels.

    hmm.. thats interesting yes the car has an intake but the sound is a lot louder than usuall and not at idle .. i took a listen under the hood and deff sounds like little rocks inside the snout. both sounds accured at the same time so im thinking its the coupler.. well atleast i hope so lol..

    take the belt off, see if it all quiet with out it.

    while the belts off turn the sc pulley back and fourth to feel for slop.

    Does it make the sound with the belt off the supercharger?

    If so, then its not the snout.

    since everyone else already suggested the belt thing and power steering and such, i will share something that i found on my car one time. it was making that loud whine noise as well, did all that crap, and it still did it. then just for the hell of it, i took the vacuum line off, and that t-fitting off that goes into the intake right under where the snout is. will that t-fitting was acuatlly hard and cracked all along the bottom. so i put a new on one, and it went away. could be somethin that simple.

    I actually know for sure that the rubber T your talking about is cracked I just can't find any in town where I live... Did you have to fabricate one from a plastic T?
