Supercharger + o/r pipe and catback = 1/4?

I finally have the funds to purchase a Vortech SQ system. My car already has a crane HI-6S igntion and Lx-91 coil, flowmaster after cat and BBK H-pipe plus autolite 3923's. My question is what kinda of 1/4 mile times will i be looking at and the MPH? I've already run my car in the 1/8thmile (closer than HUBCITY in hattiesburg, Ms) and I've run consistent 9.2-9.3's with a 2.25760ft(best with sorry 16 inch tires) at 75.4mph. At the time the supercharger goes on I'll also add a larger fuel pump, mallory adjustable regulater with boost reference and possibly 24-30lbhr injectors with matching MAF and dyno tune @ 10psi. What kind of power will I see? I'm hoping for 305-315rwhp.

For right now I'm planning on running the stock intake and gears. And I'm running 245/50/16 BF goodrich street radials. I plan on adding a typhoon intake 70mm t/b and inlet adapter hopefully at the end of August.

Thanks for the info. As soon as I can steal a friends digital camera I'll have pics up. It's too hot to go to the track right now 95-98* with the heat index in the 105's. Plus Mississippi is hella humid.
