Smooth Idler Pulley Part #?

cupcakez · 01-29-2020, 10:00 AM

Hi. Sorry if this is the incorrect spot to post this question.

Does anyone happen to know the part number for the stock idler adjuster pulley on the stillen supercharger?
I believe it's a 2.5" 8 rib width sized pulley, but I am not 100% sure so I am using my ask the audience life line.

I checked the vortech website but they dont even list the 2.5" smooth idler pulley or smaller ones for that matter (8 rib) either, so I could be entirely wrong.

Please and thank you for anyone who responds and helps out! I owe someone this pulley, which is why I'm asking where I can get it!

This doesn't necessarily answer your question, but here is the size and part or the larger pulley. I can check when I get home if I have the old one in my parts tub.

From another post:
If you switch to a smaller than stock SC pulley you won't have enough adjustment with the stock idler so you need to go to a 64mm idler pulley to take up the slack (Gates #36225)

Are guys still having to shim the pulley or is it a direct swap?

64mm is 2.5". The 36225 is 3.00". Thats what I needed when I went to the 2.85 sc pulley and stock 3.2 jackshaft pulley.

You only have to shim the sc and tensioner pulley's when you change the jackshaft pulley
