With a manual and a good driver I've heard anywhere from 15.0 at best to low 15's. An auto would probably hit a few tenths more. Just a guess on the auto but all the manual 4G's I've seen at the track usually get a 15.3-.4 during their runs with really light mods. Anything like cranking the boost and throwing on a bigger exhaust will pretty much send them into 14's.
