Your not very bright, are you?
If you look at my first post in this thread, i gave you the link to my track. In that link, the address/zip code is in there.
It was october 4th so i take it you have a hard time reading also.
I asked for you to do the correction because i was going to post the correct correction.
Just wanted to see how well YOUR math skills were.
I know BP and DA very well, as i like to drag race and most smart drag racers follow weather(BP/DA). But you probably wouldn`t know much about that.
Anyways, don`t bother, i won`t waste my time on someone like you.

And you know this for sure, without any shadow of doubt?
So now you have a crystal ball that actually predicts future wind conditions, track prep/traction (aka: WHEEL SPIN) and driver skill? Appears to me that you're trying to state that a car running xx.xx@xxx in one place will absolutely, positively, without question run xx.xx@xxx in another place but I'm sorry to burst YOUR bubble man
but no one, no not even an airplane pilot, can calculate/predict all of the variables that help make a perfect pass come together. Do most racers run better in -2000 than they do in +2000? Of course.
Do most running in these supposedly superior air conditions also
1) lose traction more often
2) have to contend with ICE COLD track surfaces throughout the enitre run
3) have to adapt/adjust their staging rituals in order to deal with cold coolant/oil/transmission temps
4) have to utilize all of their driving and tuning skills to deal with all of the above?
The answer is also, yes.

To anyone that has the interest in following weather, this is a great site to get a proper read on the conditions for the day. It gives you all you need.
http://www.wunderground.com/cgi-bin/...st?query=14481
Now after you find out what the weather conditions were for the hour you ran your new best pass, then you can add the weather conditions and barometric pressure in here to get the correct da.

How this helps the people that are interested in following the weather with drag racing.

And I'm quite satisfied with mine as well thank you.
You know, you do keep responding so apparently YOUR tampon is bunching up just a little bit as well perhaps?

Nah, I'm not real bright. Here I am actually arguing with a child or dummy about something that means almost nothing to me except to indicate you're not that bright either. Calculating DA isn't quite as difficult as say, calculating a moon shot, but it can be done rather easily with a million or so automatic plug and crank calculators available on the net. You seem to be confused, though, baro pressure is just one variable in calculating DA, just like temp, field elevation, and relative humidity. Baro pressure alone means nothing. All factors I've listed need to be known. But what I find amusing is that you actually thought you'd trip me up on something so simple (at least to me). What I also find amusing is you actually believe you're some big bad pro drag racer in your C6 street car. Now that's funny!

No crystal ***** needed (no pun intended). I rely on math mostly, and common sense of course, but yes, I would bet any amount of money I could run faster at ATCO than I have run at Firebird. And I know this because I can mathematically calculate how well it will run down to sea level and it's faster than what I've run at high DA. I don't look at math like voo doo, I find it quite reliable. Try it sometime, it's fun!
And this common sense of yours applies to all periods throughout the year as well?
Like last June at Atco when it was 102 degrees out you truly believe that you would still run quicker then you would at Firebird on it's coldest day?
Apparently you're not quite as smart as I was beginning to think you were.
But I will give ya this much...I too am quite sure that I would run slower at Firebird in July than I would at Atco in December.

Don't lower yourself to this mentality. Drag racer to drag racer, I know what you're talking about here. Keep up your dignity....it's deserved.

Hey, are you the guy that had a problem with your car back in october? What happened? Is it fixed? Design error or driver?

Well Dennis admits he'd run slower in Phoenix. Anybody else willing to take the challenge?

And I'm also QUITE SURE that nerither Dennis nor I have ever run our Corvettes in anything even remotely near a barometer of 31.24 as well.
The highest was a few weeks back at somewhere between 30.40 and 30.58 but the temps were only around 50 to 59 degrees so the barometer (at the actual track, checked with three separate handheld digital weather stations) was not as high as one might suspect, roughly -800 at best to a low of around -400 at some point during the afternoon.
FYI, Dennis's (and a couple of other's) best pass that day did not occur at the lowest DA either which brings up another point. If DA were quite as critical as some of you are making it out to be (yes it is still a big factor of course) then how come many of us have still run better times/new bests in a DA that was higher than the previous time (or times) out?
For example, my car went quicker/faster at -900 feet than it did at -1400 feet (the one time I was fortunate enough to race in that kind of air), same fuel levels/tire pressures, same driver, same sixty foots.
Any ideas?
