I was wondering because FL8PONY said because of the heat yesterday, the DA made the conditions equivilant to us running at 3000-3200 feet. I searched for a calculator but couldn't find one, I've seen where guys adjust there times for running at sea level when run at higher altitudes. Just kind of curious to see what the truck may have done if the conditions would have been better. I know it won't be exact but I would just like to see.
Thanks, Jim

 

This page has the correction factors to convert to sea level. You may have to register to see it but, the site is well worth it.

Thanks, John!
I did the corrections and I don't know if they're true but here's what the times corrected to. Base on the 3000 foot conversion number for ET and speed, this is what the times MAY have been.

Best run: 15.02 @ 91.33 converted to 14.47 @ 94.80 mph
worst run: 15.33 @ 90.49 converted to 14.77 @ 93.94 mph

The 3000 foot conversion was multiply the ET by .964 and the speed by 1.0381 to get the corrected times. I don't know if I believe it or not but I just wanted to see.
Thanks, Jim

 

I don't know either how accurate they are but, I've personally picked up over .4 seconds and 4mph from JUST better weather conditions.

I bet they're pretty close.

If you are running a Naturally Aspirated motor you will notice a big differance between weather conditions and elevation.

I noticed on my GTO drag motor on the dyno at peak power it made .5 Psi of boost on a N/A motor. I can imagine that falling off at a higher elevation.

 

who cares? that would be like me correcting my times to figure out what i'd run if i lived in new york where its cooler and less humid

 

I didn't figure this out to see what I would run New York or any where else. I wanted to see what I could have run if the conditions would have been normal for my area that night. Although, those were normal conditions for Sacramento, at least in the hottest months. I should have just turned around and gone back home when I realized it was so hot, but it was fun. The track is open until the end of November, I'll go back starting about October or if we have afreak cold spell.
