Comparative DA correction test from AZ to NJ






Timeslips are from 4-5-08 at Speedworld, Wittmann, AZ el. 1480'
This test is to see if the same car running in a higher altitude in recorded weather conditions will produce the same corrected times when run at a lower altitude and different weather conditions.
It's a somewhat loosely controlled semi-scientific physical attempt to prove/disprove the mathematical calculations on the website http://www.modulardepot.com/density.php
The car is a '08 A6 2.56 gear. Mods are Vararam CAI, Z06 mufflers, 160 stat, and a timing/fan tune. It's well broken in at 11K miles, so the 3K to get from AZ to NJ won't make a measurable difference.
The plan is to arrive in NJ or somewhere nearby by the 14th and make the runs as soon as reasonable. Dennis offered to pay all my expenses.
Opps, I mean loan me a helmet and verify stats on the NJ end.
Here's the data for the above passes for anyone who wishes to follow this thread.
Run # Temp %Hum BP DA corrected ET Corrected MPH
1 - 70.9 - 20 - 29.68 - 2932 -- 11.94 -- 121.95
2 - 69.0 - 21 - 29.70 - 2788 -- 11.90 -- 122.25
3 - 59.0 - 28 - 29.71 - 2131 -- 11.93 -- 122.20
Notice how the original times had a .14 range and a 1.44 mph range, but the corrected times only a .04 range and mph a .30 range. The previous 6 passes from two weeks ago all corrected between 11.92 and 12.00. The only change in between was the Z06 mufflers.
I intend to enjoy the trip regardless of the outcome.














Thanks for the invite.

I just gotta get my license renewed or else e-town won't let me race again. Its wierd because my license is renewed, but the photo ID is old... Regardless, I think thats the plan for this weekend. /tangent





If the track is closed then, the backup dates are the 22nd and then the 24th.The 26th is the only time I can get to E-Town, so I'm crossing my flags that the weather is good.
The Corvette Challenge and meeting all you east coast guys will be the highlight of my trip.With luggage space at a premium, I'd prefer to not bring my helmet. So if anyone can give me a firm commitment to let me borrow a 7 1/4, plus or minus a little, I'd really appreciate it.

Atco rents helmets for $3 though, so it isn't bad at all.
See you then!





I never thought to ask about that, so that's what I'll do. Thanks for the info and the offers. I think the only way I'll have a chance to beat you Andrew, is if you redlight or decide to take pity on an old man.





Yeah, those autos are consistently hampered by TM too.
Day one of the trip started with warm sunshine, progressed to rain, then SNOW
, and finished with rain again. I sure hope conditions improve tomorrow.
I live in Pennsyrainia. Now, even though I've been going to the Corvette Challenge for the last 6 years, at least twice a year they are rained out & usually at least one more is shortened by rain. Been there in snow flurries, hurricane winds, 98 degree with 95% humidity & so cold I had to wear three jackets. Fun is had by all !!
Drive safely.

Although honestly you're best chance at "beating" me is the reaction time. With my Auto GTO I could pull .0xx lights. But with the M6 I am chilling out at around 400 lights... So you may get to the end of the track before me!
