i've got an 06 nonz51 6speed... only mods are intake and exhaust, so i don't know that it'd be much of a close race... those ls3's are monsters... congrats on the purchase!!
was at atlanta dragway this past friday... old guy in a stock ls3 auto ran a 12.5xx.... i ran a 12.858 @ 113.94 it'd probably be much closer if i got headers and/or a tune...
i'm not much for street racing, but out of curiosity, where were you planning on running? are you planning on running from a roll/dig???
yeah a lot of people on CF seem to doubt the ls3 potential, but i don't see how a car making that much power won't walk an ls2, all else being equal...
where did you get your car dyno'ed at btw? i've always wanted to do a baseline dyno to see where'd i'd be at before i start the "real" mods =)
