Well we went to Fun Ford Weekend in baytown Tx, and watched all the cars run (awsome, had a ford car doing 6.5s @ 216..got out of it too) then that next morning I ran a total of 3 passes.... I ran with FULL weight + a few clothes in the trunk (10 pounds maybe), 1/4-1/2 tank of gas, my DD 285 kumhos on the 17X10.5 rims set aat 30PSI (not kidding, and I know its HIGH).... here are my results.
---------Left lane, and my very first pass.
#1160
R/T------.310
60'------1.909 (
)
330'-----5.628
1/8------8.691
MPH-----80.86
1000'----11.342
1/4------13.587
MPH-----100.29 (
we did have a 15-17 MPH DIRECT headwind)
that was my best run LOL...second run (right lane) I just smoked the tires to a 2.597 60' (launched too high and once they got going they wouldnt stop) 14.518 @ 99.76
3rd run I ran the left lane again and went back to my 3200RPM launch and backed my first run up with a 1.923 60' and a 13.613 @ 100.30. Most everyone else W/O Drs or slicks couldnt hook worth beans, infact all the bolton Gts dialins were in the 14s, and durring the ETs my dad said the best they can do were 13.7s-14.4s. Ill expand on the rest of the night later, but do you think I could have pulled a better 60' had i dropped PSI to 20 or so? (just to make this tech) Overall I am VERY happy with it. 1.9s YEA!

A buddy of mine could put his STOCK GT at 13.8 with street tires, so I definately think you could get down to low 13s easy.
