The problem is that there's too much speculation here. I have yet to see a consistant mid to low 13 second 05' on any major Mustang website/magazine/reality. Motor Trend somehow got a 13.6 out of an auto which IMO should expect no less! Yet, what we do see everywhere is people saying... "I'll bet it runs mid 13's no prob" or "with a tune it should hit 300rwhp" or "it's still too new to know" or "we don't know the track prep, altitude, weather, etc". I could go on and on. As I said in my above post...no later than next week me and my bud will be taking the 05' (stick) to Rockingham for some vids.
Someone on the Corral mentioned all it would take to get an 05' with auto to run 12's is a tune, 3.73's, and drag radials. If you look at it that way, that's a pretty simple combo for big numbers. I believe that a MTX-equipped should run no worse than a 13.5 unless the driver is a beginner or simply not driving aggressively enough. I'm toying with the idea of bringing slicks to the track to squeeze every ounce I can out of it.
