So, I took my SHO to the track and ran it two weeks ago, but I'm curious as to what others have ran in higher elevations as well.  I'm in Utah which is 4300ft and our air density is usually between 7000(good day) 7600(Crap day)

I don't have a stock benchmark, our track is flooded with 16-17 second fart cannons so runs are limited. I typically only get 3-4 passes.

Mine 13' PP with K&N panel and Unleashed 3 bar 91 tune.

Best ET, 13.53@99 (95* ambient air)
Best MPH 13.62@104 (Botched the launch because it pushed through the brakes, it was also 1am so max cold air 71* ambient)

Both runs were either low 1.9x or high 1.9x 60'

I have never run in that DA but the DA calculator will give you an idea of what it would run in better air.

a buddies bone stock14' SHO PP ran a 13.8 at bandimere speedway up here in denver. altitude 5800,DAs range from 7500-9000+. tune only SHOs are running 13.5's give or take a couple tics here. tune and exhaust SHOs low 13s. I'd say you may be leaving a little power on the table with those times but not a whole lot.

altitude hurts but hey . . at least your not NA right!

This is exactly what I wanted to know, fellow CO folks.  You guys get stuck with the same crap we do.
