Series 2 belt sizes

Post by mtcrss2006 »

Despite searching, the only thread I can find on belt/ idler pulley sizes for upgrading/downsizing the supercharger pulley is for Series 1's.

Is there a thread with various combinations for the S2 and the belt that would fit?

My specific question is what belt would I need for a 3.5" MPS change, if any?

I was running a 3.4 with the stock belt and was getting a little slip on the shifts. I kept the stock belt and went with a 3.5in pulley on the tensioner. Napa part number 209769.
