I would say 8" crank/2.75" SC. That will overspin it some though. There is a supercharger RPM calculator on the Vortech site.

I see your sig. says 12 lbs. with a 2.85 so I don't think the 2.75 will get you there. I know some guys have run a 2.50 but you would be way overspinning. I want 15 lbs. too, that's why I'm going to the YSi.

Can you say belt slip with a 2.50 pulley? And why would you want to overspin your blower that much? Hell I still havent figured out how in the hell he made so much TQ on a 346 730TQ? THATS LIKE A TURBO SETUP Ill be honest with you and say stick with what you have. Instead of a pulley swap get a YSI and be done with it. Yes you can modify the RMCR to the YSI.

There was a little chit-chat around here not long ago about the Vortech pulleys. If I remember correctly, there may be another member on here spinning a 2.5" pulley on a G-Trim. Mine has a custom made 2.62" pulley on it.

I guess the 2.50 pulley has to be custom made. I did not make the trip to Bradenton. My race car cohort Mark (BLWNTA) went down with the Ohio Boys. It looked like a good time, I saw the pics and vids.
