Vortech supercharger pulley help?!!
 

Hey, I'm getting this squealing chirping sound at warm up everyday since the weather gotten colder. Does anyone know which pulley is directly under the intake pipe that leads to the throttle body it's that pulley for sure I hear it, plus I already changed another idler pulley part number dayco 89007. Does anyone know the part number for that pulley under the intake pipe leading to throttle body?!!! Much help is appreciated to all my 86ers. By the way my squealing noise increase sometimes when I'm driving thru rpms, so I'll like to tackle this issue..😞:search::search:

I forget as its been so long, but is that the plastic pulley with the raised lip that is the tensioner, or the smooth metal pulley that gets replaced by the vortech supplied one? Vortech one is "4TX016-150 IDLER, 2.75 DIA, SMOOTH, 7 RIB"
