Well had my first run with an 07 Kenne bell GT Stang last night. (All on an enclosed private road with nobody on it. :scratchhead He has a KB with 9 pounds, full exhaust, long tubes and ya know, all the other bolt on stuff. He made 480hp and 460tq at the wheels and weighs 3875 with him in it. We went from a 50 roll to 130 and when its all said and done my front bumper was at his rear bumper. he barely pulled on me. Pretty much inched by really slow. We stopped at the meeting place and he was like "WTH do you have done to it??!!!" I said its bone stock with 500 miles on it. The reply was "HELL NO!! I beat SRT8's all the time but I could barely get by you". I said its not a 6.1L its the new 392 6.4L. He was pretty impressed with it. Now I know my car will easily pull in the 113-114 range in the 1/4 on a good night.
