This brings up an interesting point. Either the Hemi 6.1l is under rated or the Mustang GT500 is over rated.
As dyno testing has proven on the SRT8 variants, the rwhp of the srt8 has been over well over 425hp when taking in driveline loss.

Nice Try!!

But Here's the real facts!! First off alot of this soo called magazine drivers don't even now how to run these cars to there full potential,as most don't even know how too shift a manual!! In Car & Drivers case(and some others) spun the crap out of the tires coming out of the hole(Big Mistake of loss time!)and they don't even power-shift the manual!! Here's a Real Driver and his comments in MM&FF..........
MM&FF did a low 12's run in the New Shelby GT 500
MM&FF and Even Smith ran a best time of 12.25 @ 117.18 stock in the new 2007 Shelby Gt500! He ran 03/04 Cobra times 12.67 @ 110.
"I can feel this an 11-sec car with just gears" and "one should go 10's in the quarter-mile with minimal bolt-ons" was Evans comments. That 12.25@117 was with a 2.11 short time ladies and gents. Others have cut 1.85 60's so far. Being that every tenth loped off the 60' typically equates to ~.15+ in the 1/4, well, you do the math.
This car will be extra quick!!
So the charger(use that term loosely)

srt-8 with the 6.1 with higher 12's to low 13's! Down Goes Frazier!!!Like I said,I've been racing for over 25 years,...the Hemi challenger WILL NEED AT LEAST the 6.4l(500+ hp) motor to compete and try and keep up with the Shelby,...trust me!!

If they(dcx) don't,...they will be awfully surprised at the stoplight!!!
