9psi pulley question
 

I am trying to order a new belt for the SC but the S is at home. What size is the Tech2 9psi pulley? 3.5 in? There is alot of info on pulley sizes but nothing that matches up size to boost or none that I could find anyway.

Thanks,

What size is your pulley? What supercharger? Pounds leaves us guessing what size it is. Boost varies with size.

I have a tech2 9psi pulley. That is what it was called when I bought it. I make around 9.2psi at 9k rpms. The belt is slipping and I am trying to find out which one to replace it with.

Probably a 39 or 39.5 inch would work. Check out: https://www.s2ki.com/forums/index.php?showtopic=254159

Have you tried to tighten it?
