I know there's oil in it and the bypass is fine and it's absolutely coming from the supercharger or the pulley.......thoughts????

That sounds pretty worn out, but I'm no expert. I'm sure some of the "old timers" will chime in and offer some helpful input.

How many miles on your truck?

I am no mechanic but it does sound like bearing noise to me.

Well it seems to be coming from the crank, and gets worse when the supercharger belt load is on it.

Glad you found the source of the problem. I have a stock pulley from my truck that was happy when I removed it if you want a (relatively) inexpensive fix. $75+shipping in classified section.

Rebuild the supercharger. Replace bearings, check the idler pulley bearings and replace if necessary,sounds like rotors are rubbing. While your doing that, port that thing and throw a 6lber on there.:bigtu
