Hi All:
I finally got around to doing an early morning summer pass on 8/25. The temp was 82.5 F; the dew point was 66.5 F, and my altimeter setting was 29.86 inches of mercury. Relative humidity was a very high 60%. It rained hard on the 8/24?even making the national news. So, the temperature was quite a bit lower than usual, while the dew point was quite a bit higher than usual.
My weather and altitude adjusted to 500? results confirm what g-man and I have observed before. Out cars, at least to a point, perform relatively better when weather conditions are relatively bad. For example, given the unfavorable weather conditions, some of my raw results are as follows:
? ET = 14.000;
? TV = 102.02; and
0 ? 60 = 5.559.
Using the SMOKEmUP calculators, my adjusted ? ET and ? TV values are calculated below. Despite the ?bad? weather, this pass turns out to be my second best ever.
Calculate Density Altitude:
Your results:
Air Temp 82.5 (?F)
Altimeter Setting 29.86 (in)
Dew Point 66.5 (?F)
Altitude 1600 (Feet)
Density Altitude 3829.7 (feet)
Correct 1/4 mi. Timeslip to Sea Level:
Your results:
Density Altitude 3829.7 (feet)
Uncorrected ET 14.000 (sec)
Uncorrected MPH 102.02 (mph)
Corrected ET 13.345
Corrected MPH 107.092
Correct 1/4 mi. Timeslip to New Density Altitude:
Your results:
E.T. 13.345 (sec)
Trap Speed 107.092 (mph)
Measured DA 0 (feet)
Corrected to 500(feet) DA
Corrected ET 13.415 (sec)
Corrected Trap Speed 106.519 (mph)
Applying my regression coefficients to obtain the last four values below, yields the full set of weather and altitude adjusted to 500? values below. It is hard for me to know, at this time, how good these values are as I have only done two really ?bad? weather passes (which yield my two best sets of adjusted values). I know I can improve easily on today's pass since my start was not particularly good. I have updated my data in post #1 of the "5-Series Straight-Line Performance Discussion" for these values. It looks like I need to do three more passes this summer to rid myself of the remainder of my ?slow? good weather results.

Seriously, I will help any way I can. But, there's not much to do except avoid too much wheel spin--which isn't always that easy--depending on the car. I say be meticulous in everything you do being sure your meter is set properly; your strip is level and flat, doesn't have large bumps, etc.; your tires are inflated properly; you've removed unnessary weight; you brake torque properly; you obtain your weather data carefully; etc., etc. If you suspect that your strip is flat, but either uphill or downhill, then try to go both ways and average your results. You can get a pretty good idea of levelness by watching your altimeter while covering your strip and beyond its ends both ways very slowly. And, our cars are like horses; they need to practice what you want them to do so they can learn properly. My first pass almost always is mine best one, possibly because of the heat-sink effect. So, let your car cool between passes. Perhaps I don't do this step very well, but I try to be patient and to let it cool.

Exactly g-man. I'm going to post my results for a 14.07 in a while. The adusted is not as good as yesterday, but still not bad. I feel like I am cheating going out in "hot" weather.
But, the adjustments don't lie.

Hi All:
Thanks for the PMs I found. In the imortal words of The Terminator, I'll be back. I'll have some new car news. But, don't get too excited.
It's really mundane. I've missed the forum, but I run hot and cold on things. I have been posting a great deal on some Windows Vista forums.
We're on vacation again. In Salzburg now. Been to Vienna, Prague (and other places in CZ).
Cya soon.
