I want to get the 3.12 pulley for my vortech. I checked on the Vortech website and they have a Jackshaft and a supercharger pulley listed. Do I have to get both ? How do you know which one is the 3.12 they just show the tooth count? also will I need a different belt or will the 3.33 belt suffice. All help is greatly appretiated. Also can I install it and use the stock tune if I keep the surge at 8psi? All help or suggestions please. I'm new at FI !

I live in Melbourne, FL. I dont have a tuner yet. Do you know what belt by chance? Do you have the Gates P/N? I can have it ordered by the P/N from gates at the auto store. Me and my father inlaw installed the kit. So I'm still running on the tune from Vortech.

I guess I'm a little confused on which pulley I have to buy. Is it the one of the cog pulleys on the superchager or is it the Idler pulley that tensions the belt on the cog pulleys??

I got the 3.12 pulley and used the same belt that I had. There was some adjustments done to it, but it worked. I haven't tested it because a week after I put it on, it went to the shop. So i will see soon. still waiting.

Ok thanks. I'm using gates P/N K060935 right now. Is the one you suggested fit tighter or can I just keep the one I have ?

Hey bud! thanks for all the info it was a ton of help. I have installed the 3.12 pulley with the belt you recommended and it works great! I'm going to tune it Friday so hope fully I'll have some dyno sheets to post soon.
