New PB last night
I decided to race last night even though the temp here in Tucson, AZ was 92 degrees. I got to the track about 7pm and made a couple runs with temps around 84 degrees and ran 12.9 at 111 so I decided to let the temps and the track cool down. I went again at 10:30pm and had a PB of 12.56 at 114.70.

Outstanding time & mph for 3100 foot altitude and a DA of almost 3800 feet!!!
You did have a pretty high barometer and a fairly cool evening, but that track is pretty darn high. Your time corrects out to 11.98 at 120.0 mph for a sea level standard day. Excellent!
What 60 foot time did you have on your best run?

My 60' was a 1.986. It really wasn't that cool either. I know the timeslip says 67 degrees but my car and the weather report on the DA calculator says it was hotter. My car said 72 degrees. At 11pm when I went home I still had the air turned on. This is the first time at this track that it hooked good when it shifted into 2nd. Usually I spin quite a bit

As far as how much better you run, depends on the weather. You had a 3800' DA, I've seen the DA at Firebird be that or even higher. I've also seen it around 300' on a very cold day. If it's in the mid 80's with a standard barometer and 19% RH, you should run around 12.4 at 116.
