well i personally have run 13.5@105 at kil kare raceway this summer in ohio. this with typical aug weather in ohio. my 99 is bone stock, all that has been done is routine maint. this on my usual crappy 2.2 60fts.
any factory car has there up and down in performance and to make it even worse you have to factor in the driver and weather when you compare times.
so is it possible there are factory stock 12 sec 1/4 mile ls1 cars out there? sure. i would not call that the norm though. most i've seen run mid to low 13's.
i would actually call mine one of the slower ls1's. i've driven mine long enough and i still go around and test drive a few here and there (just for the he** of it
) i will not forget 1 particular ss i drove. with 15 miles on the odo this 2000 (yes this was back in 2000, so it was new) made my ws6 feel slow. this driving them back to back. so the factory freaks are out there.
oh, and if everyone wanted to post what an ls1 ran off my 1st run down the track in it, these cars would be running mid 14's then.
