How fast a car (quarter mile E.T.) would you be willing to drive at the track? On the street? I've been told by a few who have done it, that by the time you're in the 5's, it physically hurts bad enough that your brain has to be acclimated by forced repetition. Personally, 9's is my fastest ride so far, but I'm up for about pro-stock level (high 6's).
