I'm running at what I call stage 4 on an auto TT, and I know for a fact that any decent driver of a manual with same mods will beat me. Just an FYI, I haven't been to the track, but there is a 1/4 mile marked on a rural road in the area...and according to my speedo, I go through at 110-112mph. Most sticks are going 118 or higher with same mods. But I think I've read that the taller gear ratio of the auto does allow it to have a higher top speed...but how often do we get to test that :)
