I'm trying to figure out what my 1/4 mile time would be, when accounting for humidity, temp, and altitude. It was 82% humidity, 80 degree's, and as for the altitude the best info I can find is that its 1000 feet above sea leval. Any ideas guys?

P.S. my best run was 15.863@85.78mph

1/4 mile times are depependent on a great number of things that we just dont know. how good of a driver are you? what kind of condition is your car in? running street tires or slicks?

I think of myself as a good driver, I was running street tires. The car has 185k and all my mods are listed in my signature. I thought there was a forumla to figuring out what the 1/4 mile time is based on the ambiant condtions?

Yeah Ryan, there are formulas to adjust times to STP (no not the band, Standard Temperature and Pressure). I don't have one handy ***. :(
Either Car&Driver or Road&Track adjust their times. Every other year or so they publish an article on how they do the testing. I just need to find one of them. Maybe someone else can come up w/ it in the meantime.
