I have no idea what the DA is or was? lol

But for the first couple runs we did have a slight head wind, then it turned to the side later in the day.

I also have two switches that I installed under the dash, one turns on the electric fan, the other turns on the aux water pump,
That way when Im sitting in the staging lanes, I can cool off the car without it running.

The best run (third one @ 12.6) I was sitting one car from the burnout area for 45 min while they cleaned oil off the track. I got to start the car, pull right into the burnout area and line up, the temp gauge was only 1/4 of the way up.
The other runs I was able to cool off the car in the staging lanes, but by the time it was my turn, the car was already up to temp even with the fan running.

So...that tells me it runs much better when its cooled off.
I think I may look into a t-stat swap or even a water/alc injection kit to cool off the intake charge.
