From what I heard, but I could be wrong, if the supercharger is going you would know. It makes a very terrible sound (gears grinding). You might possibly have a vacuum leak or some kind a leak going on. You might want to have your buddy rev the engine and pin point exactly where it is coming from.

 

Hey thanks for the reply
Does anyone know how to put video in a reply? Do I have to youtube it then put the link in... I took a video on my phone and you can clearly hear both noises.. Thx for the help
And btw.... If a vacum line is leaking wouldn't you feel loss of power? With both noises there I still feel full power ... And would a boost guage help me find out if I have a vaccum leak? Thanks

 

Yeah... upload your video to Youtube and link it.

Whistling doesn't sound like a faulty SC, which is more of a grinding sound when the gears no longer have oil between them.

 

finally got the video up the loud whistle is almost over powering... toward the end of the video i leave her at 21xx and you can hear the loud whine

Well the good news is it doesn't sound like the supercharger. Obviously I can't tell from the video where the noise is coming from but to me is seems like it might be coming from the belt line area... Maybe a bad crank pulley or damper or something. Try taking a better video so we can see and hear exactly where its coming from.

 

doesn't sound like anything is wrong with the SC.

 

does not sound like the suprecharger as in??? the whistle maybe a belt or pully like said before but the very loud whine sounds like its from the charger

 

Sounds like a glazed belt and maybe the belt tensioner.

 

Have you had any luck determining what is causing the loud whine/whistle. I have a 03 MCS with 50K on it and just started hearing the same random noise. Sounds like it is coming from the area near the air cleaner box, just towards the firewall.

 

If you mean the intake, it is supposed to make a whine due to the supercharger. Also i cant believe this is your first post and you have been here since 2004.

 

Been lurking. No, it isn't the normal SC whine. It is a loud whistle. Just started last week.
