How to diagnose a failing Vortech idler pulley?

[jwt390030]

Hey y'all,

I am trying to diagnose my idler pulley. I called vortech and they told me to diagnose the idler pulley before thinking that my supercharger is needing a rebuild. I have a groan coming from the engine compartment that is not too good. I hold boost just fine, i am not losing oil, but I cannot figure out which pulley is s^&%ting the bed.

Any help would be great. I have a 95 Cobra with a standard V2 sq setup.

Cheers,

John

Remove the belt and spin each one by hand. It should be smooth and quiet. Any grinding sounds/feelings means the bearing is shot.
