My car has been squeaking. I have replaced the belt 3 times, and now the tentioner pulley. It looks like the idler pulley is out of line and makes a humming noise when I get on it. Does anyone know the part number for the idler pulley from the zzp supercharger kit on the 2.2/2.4?

 

is that the one unique to the kit?

 

It is and that is why I would never get the ZZP sc kit. Not a fan of the idler pulley deal they use. I'd rather swap all my pulleys to 6 rib jobs and call it a day.

 

If only I knew this beforehand...

 

My best advice is to remove the pulley and check if any local speed shops or regular old mechanics have swapped out a similar pulley. Maybe see if the local autozone or what have you will let you match the pulley to their stock. You got options but unless ZZP tells you where to find it you're gonna end up having to pull it off your car first. Be real nice if the ZZP staff just shoots you straight.
