I saw two Challenger SRT8s run last night, one ran a fairly consistent 13.5 at 107-108 mph, the owner felt he could get better times with different launch results.
The other car was identical (same color too!) but he claimed his car was bone stock yet he ran 12.9 at 114mph.
114 mph!!!!!

I could believe the 12.9, but 114 mph for a dead stock SRT8 seems a bit high?
