Default Re: "Live From" JEGS SPORTSnationals

My info was taken from the website airdensity.com it is a very good website as you sill see if you go to it it has most tracks on it and if they don’t have one you want just call them and they add it. I have used them to verify info when I was on the IRL team. We had one of the Mercury barometers. When we got to a race track I would call nearest Airport for the actual station pressure to get their reading. I would suspect that Larry’s baro was set up to something other than actual baro reading at his nearest airport. I was sure when I seen his baro reading this morning it was off. I raced and tested at National Trail many times and have never seen a station pressure that high National Trail actual altitude is over 900+ feet. We used to care a altimeter instead of a cheap baro. If you at the track set it to zero feet and look at reading for the actual station pressure right where the Altimeter is. That was the way I did it when I was Dragracing. When I was at Ford in early 60s we had the Mercury Baros at the Test Tracks and at the Dyno building. As far as the website I listed. I have e never asked them where they get their data and who’s all that data entry but I’m going to call and ask tomorrow.



QUOTE=Stan Weiss;643743]Ralph,
I am confused (that happens a lot these days). If the 29.71 BP Larry posted is corrected BP and you show corrected BP as 30.20. Why are they different?

I was thinking maybe corrected BP - Vapor Pressure but that does not workout.

OK what I did was ► 30.2 - .527 = 29.673


What I see now is that Larry's temperature and RH% are not the same as yours. If I calculate what his VP is ► 30.2 - 0.4935 = 29.7065
