2011+ GTs run mid 12s bone stock as long as they aren't at altitude, even the autos. Guys with intake, exhaust, and tune should be in the 11s.
mid 12s is even generous..the majority of the guys with the race tunes only are running that time. I was just at byron dragway today with some people and my dad made a few passes with his 12 GT which is bone stock 3:31 gear..ran some horrible times since he couldn't get it off the line for sh*t and missed 3rd gear both times running a 15 flat..next up is a barton shifter to make the shifts easier to bang. There were however a couple other 2011-2012 GTs there, one with bolt ons and what sounded like different cams that ran an 11.80 on DRs..as well as a stock appearing GT on DRs with a whipple blower that ran a 10.20 at 137 mph..deffinetly a sleeper.
