I'm going to say 4.6 sec. for the LS3 but I want it to be 4.4 sec. I'm hoping for a 12.6 quarter mile time.

The reason the numbers are not coming out right is that the car won't shift 6 times in the 1/4 (at least I think that is what you meant). Actually, the manual car will shift into second just before 60 (about 55), and the auto shifts into third at 66, which is why the auto runs much better to 60mph. And in the quarter the manual uses third gear through the 1/4 mile (to 114 mph), while the auto shifts into 4th gear at about 102. This is why the auto has a slight edge, it is geared more aggressively for acceleration than the manual. Don't ask me why they did that, I would think you could dedicate 4 gears to the 1/4 mile run with a 6 speed manual tranny, and still have plenty of room for overdrive, but oh well. They really geared this thing to keep revs low to help fuel economy I suppose. As for the calculator, the manual car will shift only twice (1-2, 2-3) in the 1/4. I guess 4.5 auto, 4.8 manual 12.9 auto, 13.0 manual, both at 108 mph |

Edmunds shows slower times because by default they don't shave off .3 seconds for rollout like everyone else does. When you're feeling 0-60 the rollout isn't something that will count for anything; it is just a timing technicality.

ps Bracket racing sucks. Isn't the whole point of drag racing to prove who has the faster car, what exactly does bracket racing prove? |

nope.
1. lights, the Auto has the launch control, and will get off the line quicker, and it hits 60 quicker because of how they timed the shift pts. 2. with Drag the Auto will just outshift the manual, unless you dont like your car and powershift the shit out of it. and honestly id rather loose in an auto than win damaging my car. |
