Should temperature effect my quarter mile time this much?
I couldn't believe how frakin slow the car was tonight:
Reaction .585
60ft 2.28
660ft 9.724
1/4 - 15.060
MPH 92.78
With my mods I feel like I should be faster despite the 60ft time. I hope nothing is wrong, but everything seems ok just s-l-o-w.

This is too little information to determine a problem if there is one. But high temps and high moisture content will cause lower numbers. What you should look for is relative numbers of other cars at the track. That helps to discern if it is your car or all cars.

the elevation around cincy varys between 400 to 900 ft above sea level. I doubt that played a big part...I bet it was the Temps.
If the weather is nice I might try and make it to Edgewater on this wed. if you wanna go

Okay... here is your answer:
From conditions above at 6PM:
Density Altitude: 2171 ft
From the NHRA table here: http://www.tsrsoftware.com/nhra%20el...%20factors.htm
The correction factors are: ET: .9744 , Trap MPH: 1.0269
So your corrected times:
ET: 15.06 x 0.9744 = 14.674464s
Trap MPH: 92.78 x 1.0269 = 95.27 MPH

Now the Ultimate web page would do:
1) extract weather conditions from: www.wunderground.com The have tabular format for the weather conditions:
2) Using HP correction factor calculator from: http://wahiduddin.net/calc/calc_hp_abs.htm
3) Use the correction factor for ET and MPH from http://www.tsrsoftware.com/nhra%20el...%20factors.htm
Using your time slip numbers ..Dyno numbers if know.
Generate the table of the time, weather conditions, Air density and HP correction factors, corrected HP and Torque, corrected ET and Trap, estimated HP from each run...
Now that would be awesome!
