based on your whining, I'm guessing you want to know what HP mods are needed to get into the 12's. You're not taking into account the suspension mods and weight reduction that will cut .50 1.0 seconds off the time. A bone stock GT 5 speed should be able to run 13.9s. Take some weight out, pull the front sway bar, and put on some ET streets and it should run 13.5's. Add 4.10's, timing adjuster, and exhaust and it should run 12.9's. Put some fox springs on it, launch a little harder and run 12.8s.
