Track Altitude? and some better times
here is my run from the other night:
1. 04 coupe
2. 6spd
3. Street
4.Orlando Speed way
5. Temp 77, humid 94%, pressure roughly 30in., dont know the altitude of orlando speed world though...
Best run of that night...
60' - 2.191 (worst of the night)
1/8 - 9.224 @ 78.97
1/4 - 14.155 @ 99.66
Mods: Borla TD, TPs, and Ztube
I will post my slip soon and my digi is working again!
i was trying to figure out my corrected time but couldn't find the altitude of OSW, anyone know where i can find that? or could calculate my times?

Good times. 13's are possible with your current mods with a better launch & better conditions.
Look whose back

Good times - particularly the launch.

What was the day, and what was the time of your best run?
You need to know the exact conditions, because at 77 degrees and 94% humidity, 0.05 difference in barometric pressure equates to a difference of 57 feet in density altitude.
If you have the date and the time(to within about 15 minutes), you can use wunderground to approximate the conditions. Orlando Speed World is located in zipcode 32820. Using this information, you can look at the historical hourly break down for the zipcode.
For example, here's the breakdown for last friday night(the 18th): http://www.wunderground.com/history/...q_statename=NA
Assuming, for this discussion of course, that you ran last Friday night at about 10:00 pm. The conditions would be thus:
79 degrees, 79% humidity, and a pressure of 30.05. Those conditions, with an altitude of 106 feet, yield a DA of 1611 feet.
You can use a different link to correct your ET: http://www.modulardepot.com/density.php
Using this information, your run would adjust to a 13.93@101.24; of course, that's only if you ran last Friday night at ~10pm.
And keep in mind that it is only an approximation. My best run is a 13.264@103.96mph. That was performed in 975ft DA. Adjusted, that time would have been 13.13@105.05. However, a couple months after that I went to the track again, with damned near 0 DA, and my best time of the day was a 13.30x@103.9x mph. The correction, for my car on that day, had no basis in reality. (but I still like leaving the correction in there
)
