Need advice

i dunno if this is right or not
6lbs boost on top of ~14psi normal air pressure would be 20psi going into the engine.
20/14 = 1.429
190 x 1.249 = 271.51
271.51 - 190 = approx 81 hp?
i have absolutely no idea if that is correct or not. there was a kid in my intro to engineering class who was telling me thats how he found out how much hp his s/c cobalt was making. i would think a supercharger would add more than that. but i could be completely wrong. i couldnt find any numbers or dyno sheets on their website

I wouldn't go over 33" tires. The drivetrian wont survive with 35" tires, unless you baby it.
To get 33" under it you have several options.
Fender trimming.
Body lift and fender trimming.
6" suspension lift.
To get bigger tires, go with a solid axle swap.
To keep up with your friends, install the 33" meaty tires (however you like) and install a rear locker and front limited slip. Then remove your front sway bar, or at least disconnect it, and install some 2" shackles in teh rear and crank the front t-bars 1". With this set up you will have good ground clearance, they will have maybe 1" more if they are running 35" tires. They will have better articulation, however a good driver can get around that most of the time. Most of the limitation is the driver, not the vehicle.
