97 Park Ave Ultra LOUD supercharger noise

I have a 97 Park Ave Ultra, which has so far been a great car! However recently the supercharger started making a squealing noise which was shortly followed by a LOUD growling noise but only when its taking in air. At idle I will only hear the squeal which I believe is the belt. As I accelerate the noise sounds like a loud growl and does not seem to coincide exactly with the engine rps as it gets louder and softer, which is what leads me to believe it is the supercharger. Its hard to directly monitor where the sound is coming from although im 90% sure its the supercharger, because I have to be driving to hear it... (also when making turns and out of direct air contact the noise stops) I changed the supercharger oil, which was DARK brown :th_nervous:... but it didn't help at all.... is the supercharger just dead?
 


Check your belt pullies asap. I'd bet one is getting ready to fall off and leave you beltless on the side of the road.
