here are my times from e-town, keep in mind this was my first track event. my scanner's acting up so i'll type everything out. how do you correct the times for weather? temp: 43F barometric pressure: 30.38 Hg / 1028.4 hPa wind: 5-10mph from west the track runs northeast -> southwest run 1: tires at 37psi all around, tc on, motor was cold (2h cool down, then ran for ~3 minutes before i staged. xfer case test happened as usual @ 20mph) 3:17pm march 3 2008 r/t .759 60' 2.057 330 5.599 1/8 8.547 mph 83.77 1000 11.068 1/4 13.277 mph 101.50 run 2: tires at 37psi all around, tc on, motor was warm, @187 (kept the fan on by running the heater. xfer case test happened as usual @ 20mph) 3:49pm march 3 2008 r/t .630 60' 1.963 330 5.521 1/8 8.493 mph 82.88 1000 11.040 1/4 13.198 mph 102.07 run 3: rear tires at 33psi, fronts at 37, tc off, motor was warm, @187 (kept the fan on by running the heater. avoided xfer case test during run by accelerating over 20mph prior to staging) 4:35pm march 3 2008 r/t .667 60' 1.834 330 5.359 1/8 8.322 mph 83.03 1000 10.862 1/4 13.019 mph 102.14
very nice... That last 60' was awsome. I am assuming you were on Street Radials? http://wahiduddin.net/calc/calc_da.htm
I gave you a link in my first post. You will need the track elevation and the humidity as well. I did a guestimate and came up with a negative 1200 DA...
Altitude 86 feet Air Temperature 43 degrees F Altimeter Setting 30.38 inches Hg Dew Point 37 degrees F gets me this: Density Altitude -1451 feet Absolute Pressure 30.286 inches Hg Relative Density 104.32 % what now?
corrected, my best 13.019 @ 102.14 becomes 13.18 @ 100.86, disappointing for my setup. there was a stocker w/ cai that ran an uncorrected 13.24
