Try spinning the */C pulley with the belt off and see if there is any friction.

Sounds like it could be but what fuddyduddy121 mentioned to do is the surefire way to know if your coupler is going or not.

i have also been considering getting a smaller pulley for the sc, and i have seen that some pulleys come in kits. would there be any kits that would include the coupler, and if so where could i get one from/ what size would i need.

ZZP has the best coupler on the market now. this summer, i thought my coupler was going bad, after taking the belts off, i found that the balancer was broken, the rubber breaks, but about idle, the noise was gone. this is a common problem that GM redesigned the way they use the rubber section now.
what mods do you have so far, a smaller pulley alone wont give you much, with it , you need to improve your airflow in and out of your motor, and trust me on this ok, cold air is your friend with a smaller pulley, insulate everything on your intake system before it gets to your SC.
KR is a power killer and heat is the main factor of that.

i am going to get the air intake next anyway. I may need some help with the air box though, so ne design help would be nice. As far as zzp goes it looks like that have something similar to what i am looking for, but i would like some size sugguestions and price estimations if anyone has them. i am probly going to order within a few days, just as soon as i feel secure enough about what i know to buy one.
