Some racers run 13.70 seconds while others 14.70. So its difficult to expect anything. Why not run, then adjust your ET using this chart:

I went and the best I got was 14.7. I think a lot of it had to do with my bad driving, lots of wheel spin and 60' times of 2.5-3.3
. I plan on going again soon for more practice.

Using Davidv's table, I took your altitude and figured a best of 13.9@101mph to come up with the 14.5@97. A 14.7 at your altitude with a 2.5+ 60' is actually really good.

Went to the track last night. I was dissappointed my best was a 14.3 with 2.3 60'.
Then again my girl was riding with me, and OSW is slicker than Hell.
The other Z there, it was his first time too, ran a 16.00. ???

I do believe it is more than just track elevation that affects car's performance. Even though my local track is only 435 ft above sea level, our density altitude is well above 3k ft during the summer due to heat/air pressure/dew point. Because of that, I use density altitude calculation to figure out what my time would be with sea level altitude rather than just using altitude correction factors.
