Jrsc belt slip...I think

Ok so heres the situation. I was passing someone because it was about to turn into a 1 lane road, went into boost past him and pulled up to the stop light and there was a squeeling/sweeking noise coming from the motor. I pulled over and the noise went quiet. Drove it home no problems. Now I noticed today when I was driving it I was only getting 3-4 pounds of boost at wot, when Im used to seeing 8-9. When the boost gauge goes above 0 it squeeks like the belts slipping but nothing looks to be wrong. Not sure if its a pulley or the tentionser or the belt. The belt is still tight around the blower so I'm not totally sure whats the problem. If anyone has had a similar problem please chime in. I'm not trying to drive it if this a more serious problem.
Thanks again
Ryan

Edit. On the way to school today I drove it for 5 minutes with no noise, then I pulled away from a traffic light and it started to squeel like no ones business. I pulled over and every time I touched the throttle it would squeel like crazy. I shut the car off then turned the car back on and the noise went away and made it home. Now Im really concerned about this noise. Video will follow later so u can hear the noise

Sound like belt slip. You could take the belt off and inspect it, spin all the idlers/pulleys to make sure they spin smoothly. Also you should check to see if the tensioner has a strong recoil. You might just need a new belt.

Nail on the head. You were right. The bracket that goes from the alternator to the supercharger came loose. The bolt came off somehow lol. Well it is fixed and drives like new. Thanks guys

^^it just happened to me.lol I thought my tensioner went out and put a new one on. Belt was still loose. Got a smaller belt I thought I stretched mine(known to do that). And then bam the bracket was loose. Red loctite and lock washers and nylon nuts fixed it

I wonder if this is the same problem I'm having?! I know the OP said his bolt was gone, will it squeal if it is just loose?
