Octane?- Happy Medium- Boost?

[McLovin]

Ok guys need a little input here, im hoping to run 15-18lbs with my phazer, it has no head shim and all stock internals. The stock compression ratio is 12.4:1 and will stay there. I have the ability to add plenty of fuel and air- so thats not an issue, the issue is i can get a barrel of sunoco 112 for $395 what kind of boost could i run with this fuel? Any one? By the way sunoco figures there fuel with at the motor octane so that is 112 at the motor. I would think the internals would be just fine as long as detonation is not present.
Any Input?

I recomend putting a head shim in, u can run even more boost with that 112, because 112 is not enough to go 16lbs with no head shim. unless u have a timming control box.
i did before with no head shim and could run 15 lbs with 100 octane but my timing was retarded big time. www.goturbo.ca
I have a 07 phazer with a synergy kit, put the head shim in after i bought the sled/turbo.
