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.
First off I'd like to start this response on a positive note so that I'm not pissing off everyone by saying that the 392 is a very impressive engine and has adequate power for the street. Now with that being said and me having been the owner of MANY Mustangs from 2005-2009 era that were supercharged I'd like to say that while I believe this may have been the actual outcome, I will say he must not have downshifted into the right gear or didn't downshift at all to only gain a car length on you from 50-130. or he just doesn't know how to drive period.
Case in point, I have a 2007 Roush Stage 3 with 435 crank hosepower that will run away from my 2011 SRT-8 any day, any place, any gear. The car weighs less, and runs low 12's in the quarter at 119 trap speeds.
If he had 480rwhp (which had to be forged or he would have left rod depsits all over the highway) he would have eaten the 392 alive had he known how to drive. A Mustang with 480rwhp will run high 11's or flat 12's all day on street tires with 0-60 times sucking due to lack of traction, but open those monsters up on a run and forget it. The Dodge is a great car, but come on man. It is not going to run with a blown Mustang running that kind of horsepower. It will barely beat a 412 CRANK horsepower 5.0 stock GT, if at all.
How the hell can you say a car with 10 more rwhp then our cars have at the crank, AND weighs in a few hundred pounds less at that, will only pull away by a car length in an 80mph stretch?
Bull freakin sh!t.
