For St Louis I ran the 10.00 index and won the True Street 10 sec cutoff. For Martin I bumped my index to 10.25. (and broke the trans ) K

Compare ET to new weather conditions Leave the 2nd ET conditions at the sea level values and compare your Tulsa and Norwalk to sea level conditions. Or put your Tulsa ET and weather conditions in #1 and Norwalk weather in #2 to see what it would run at Norwalk using the Tulsa run.

I've always heard it used in a relative fashion, such as those times when you have a DA thats radically lower than usual. In the Midwest, its the late fall season time when your stuff runs better than it has a reason to - the cool days where the humidity is negligible and the Baro is way up.. Great for setting those Personal Bests that any other time of year you cant get close to running again.

I would think at your power level u should see about .06-.08 for every 1000 ft drop if the cars tuned optimum!

I have to assume you were at Norwalk...lol. I am still stuck in my youth on the burnouts but I do go all the way to 3rd with it so I don’t roll out in 2nd. I also need to get a different spring rate in my car front and rear because I think I can get a 1.2x 60 out of it...still foot braking it...

Some real data from my travels over the past couple years. My wife and I race 1/8 mile predominantly and have traveled from Minnesota to Florida and many tracks in between over the past three years. My car has run as fast at 5.27 at Huntsville and Bradenton with -300 DA's. We ran 5.49 this past weekend here in Minnesota with 3300 DA on a bad track. This is the exact same car with jetting changes only. Our engine/trans/gear combination has not changed in that time. For comparison purposes my 1/8mile ET's at Norwalk in the Q16 5.34-5.36. Hope this info is helpful.

Considering the air at Norwalk, I'm confident you'll go 9.20s closer to sea level. How's you 60ft and mph? |

Mineshaft air?
Quote:
My 3 Saturday passes, the last one was a 9.92 but it broke all the torque converter bolts off right around 950 feet into the run and just coasted. You can see the best 60 and 1/8th was the pass the bolts broke in first round of eliminations. Friday night I went 6 rounds in the gamblers race and took home a little money. Of the time run passes I made this weekend 9.46 was the slowest and 9.42 was the fastest and I foot braked it every pass, shift it myself by ear as I never pay attention to the tach...lol Sent from my iPhone using Tapatalk

Your first two slips show the exact same et from 660 to 1320 so the third slip would've been a 9.402.
Your 60ft is slightly less than optimum for your et. That said. Better air will prudish more power, which will work the converter harder. You will run 9.2x or so in "mineshaft" conditions. Assuming the car hooks, it should go at least 1.29. Probably quicker. |

Best air I ever saw was at Sears Point in the winter, something like -800’ DA.
Just log & track performance against the DA. It is the accepted method when calculating aircraft performance, so it will work for you race car. Keep in mind the atmosphere is constantly changing and the DA method simply compares current conditions to a “Standard Air” which only exist in theory…it is a yardstick for measuring air, so to speak.

The old Fremont Drag Strip in the Bay Area had about the best air possible. On a big High Tide it was close to 0' elevation.
I hear the property is still undeveloped since its closing. Sad. |

Well yeah, on the east side of the salt flats in the bay, yes it is very close to sea level, as you refer to as the “Best Possible air”. There are a lot of drag strips around the country that are close to sea level. What you fail to recognize is the MSL is fixed, it will never change, The atmosphere is the great equalizer, it is a living breathing animal. It can and will change.
