Adding a pulley or even a twin screw blower does not affect the car in normal driving conditions whats so ever. when it is not under WOT it is not running at any boost and is the same as if it was stock.
A pulley/intake/catback/tune could get you running 11's depending on how good of a driver you are and what type of tires you are using. Depending on your budget I would do the mods above plus some Drag radials. Once these cars are pullied they eat street tires and really like to wheel hop even more so than stock. DR's will cure the wheel hop and get you off the line. I doubt you will be running consistent 11.5's since you said this is the first car you have had with power. Best combo for a consistant 11.5 cobra is a ported eaton 2.93 upper/4lb lower, sticky tires, and some good driving.
