i dont know how to do the calculation for the 1/4mile time correction. i have the time slip of when i ran a 13.9 in san antonio tx but i dont know how to find the altitude and density and all that stuff. the time and date is on the slip, id appreciate it if someone did the calculation for me. Thanks!!



sorry about the big pic.

 

Density altitude for that day was -300'. Basically as ideal as you could wish for. Your engine was making 105% power due to the oxygen rich area.

San Antonio, TX
Elevation 600'
Temps - low 50s
Dew point - 18 degrees
Baro - 30.34
