m90 making weird noise

my car started making this horrible noise last week i think it is the bearings but i figured i would post a video of it to see if anyone had experienced this before.

I have another sc so i can grab parts off that if someone can point me in the right direction.

The noise stops when i took off the belt and at that point i put on a new idler pulley. I happened to have laying around so it is not that. The smooth idler and the tensioner spin freely.

The sc pulley feels like it has slight play but not any more than the spare one i have, and it never made any noises. i have a green coupler in this one.

here is a awful video i took with my phone but you can hear the noise

mine sound simalar... 97 gtp 221k... runs strong... the boost doesent really pick up like i thought... and how much play in the sc pulley is too much play
 
If you dont get boost that quickly, might be time to inspect your rotor coating.

Though I found on a stock pulley, boost was slow to build.

With a 3.4 its much quicker.
