9.5:1 would be best for 12 lbs (considering 91-93 oct). You could be running 14-15lbs with your CR (considering 91-93 oct). Get a new belt & tensioner for the belt slip. Instead of a smaller pulley, try an overdrive crank pulley. You could go 8-rib, but it's not really needed for that level of boost. Considering you have the P1, I would say the overdrive crank is your best bet since you'll be spinning it so fast.

Not on pump gas... high comp & high boost will always make the most power... on
race gas.
