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.

Nope. He has the 150 shot numbers below it. Ive asked him last time and he never replied. Oh well my numbers will never be there anyway with the 4l80 going in. Hello track

theres no way he made that much torque w/ an sc and a forged 347.

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.
