Evan Smith got a stock 99-04 Mustang GT through the quarter mile in 13.7 seconds, but 13.9 is more realistic with a good driver.
My best stock was [email protected] that was a 01 5 speed car stock with crappy kumho tires
Sea level and good weather has a lot to do with it, that was in really good weather but on a unprepared track ( NED does not want the track sticky on street nights)
Evan's times were at atco in good weather on a well prepped track, he is a excellent driver, I think if the track was prepped as well as they do for those tests I could have gone 13.8
BTW i saw I replied in this before. I went through my slips again and the 13.8 run was with a K+N + flowmaster cat back so the best bone stock was 13.903
