How much boost?

[RoadWarrior]

Well after some deliberations i think i have made up my mind on what my goal for the stang is. Ive been looking into some sort of unnatural unduction and ive come across the Holley PowerCharger. Ive always like the idea of a nice roots blower sittin on top of my engine stickin out the hood and this one seems like it should work pretty nice. What im wondering is if anyone here knows roughly how much boost i could run with a compression ratio of 9.25:1 right now. Pistons are probably also going to be replaced but right now im just curious. This isnt going to be happening for a little while i just want to see if i can finalize my plans and maybe get something underway. But the first thing is still going to be just getting the stang painted and put back together. So what do you guys think?
