What exactly is "DA"? I have been wondering about this and couldn't figure it out myself. LOL

Re: What exactly is "DA"? I'll keep it simple..
It stands for Density Altitude. It's basically effected by temp, humidity, barometric pressure and altitude. The denser the air, the more oxygen it holds per volume. More O2= more horsepower <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />

Re: What exactly is "DA"? For more information regarding DA go here http://wahiduddin.net/calc/calc_da.htm.
If you are trying to figure out the DA on a given day find out the altitude of the race track you are going to than go here http://www.wunderground.com/ and grab all the necessary information and plug it into the above calculator and it should give you the appropriate DA. Hope we helped!

Re: What exactly is "DA"? Don't they make gauges that'll read out DA? If so, where can they be found. I'm looking at least for a good set of portable gauges for at least humidity, barometer, and temp. I'm not really sure where to look for stuff like that though. Any help would be appreciated, thanks.
