Wow man, that's definitely a low to mid 12 second run if you don't spin through the first 60'!! A 2.3xx 60' time is absolutely horrible, so if you get good slicks and a nicely prepped track and produce a 1.9-2.0 60' time you'd be golden.

120 mph traps will put him well into the 11's.

Yea 120mph traps do get you into the 11s, but it's also proven that crappy 60' times result in higher traps but obviously lower ETs. I would say high elevens low twelves since he can't find traction.

you're going to have to explain to me how having less traction = higher traps.

this was done with no tuning yet either. it should be deep in the 11's with tuning and slicks.

I know I didn't believe it either because it's not really intuitive, but cars usually trap slightly higher if they have slightly worse 60' times. I did a quick search in google for "higher trap lower 60'" and low and behold a mustang forum link came up. Reading through it most people acknowledge this fact.

"anyway, the best way to describe why better 60' equates to better ET but LOWER mph would be along these lines:
getting traction off the line means a harder launch and better 60'. in the same sense that a good launch gets you to 60' down the track in less time, it would also get you to 1320ft down the track in less time than a bad launch (in theory). however, since you got there quicker, your car had less time to accelerate up to its maximum potential speed (trap speed). because it was accelerating for less time while physically within 1/4mi, it did not have enough chance to get up to a higher speed vs. a run with a good launch, BUT it got to the end sooner. this results in lower ET, as well as a lower trap speed."

So this guy with a badass fox body mustang with turbos is making insane power which still gets him very respectable ETs even when he has terrible 60' times with no tune. HP determines ET, and lower 60' usually result in slightly higher traps. So when he tunes and runs elevens, I bet he traps 116-118 with a time of 11.7-11.8sec.
