My very first run at the track I ran a 14.1 at 99mph with spare and jack , the next friday after that I ran a 14.0 at 98mph w/o jack and spare , with synthetic oil and an air hog air filter !
After a few launching techniques and tire psi adjustments I ran a best 13.932 at 98.82 mph .
The only thing is my freind has a 2003 GT auto and his best times were in the mid 14`s . but that could have been his driving .
