Ok so I'm using a gates k070890 so 7 ribbed 89 inches with the 9.5 lb pulley should I be running a smaller belt? Its the s.c. with two idler pulleys. thanks

 

K070905 GATES BELT is the belt size for running the 9.5 lb pulley

check the supercharger thread also for the right size

-edit- thats for an 07- up S/c. for a 05-06 its the one u stated. probably just buy a new one if its slipping, mine has slipped off twice already (in the rain), waiting on some nst pullies to change to a new belt though hope this helps

 

Make sure you didnt get a drop of antifreeze on the belt. It will make it squeal like a piggy.

 

There's nothing on it really atleast not antifreeze. The belt just has a good amount of play I was looking k070895 which is half an inch shorter

 

Also how could I "clean" the belts to make sure its not something on it. It seems to me moving side to side on the idler pulley closet to the firewall and has some play in between each pulley. Belt is brand new.

 

well if you end up wanting to buy a new belt. i have 2brand new supercharger belts if any one needs one and one used has only 20k miles on it send me an offer if interested.

 

Well aparently the previous owner used it for 5-6k before me. Would the half inch shorter belt fit? I just hate this squeeling sound. Also if anyone has a tune for f/ic pm me
