Hey, I was only having fun with you East Coast guys. However, if you want to race, it will have to be at a Solo 2 event, not the drag strip. It takes a lot more talent to get the car to do what you want to do in 2 dimensions instead of just one.

As far as -2000 DA, sorry, I was exaggerating to make a point. However, I know most of you have run with negative DA's. I'm lucky to have anything under 2000 feet where I live.

I'll continue to correct my times only to make sure that my car is still running correctly. You would be surprised how accurate it is.

And one more point. Why should I turn my car back to stock? According to you, since denser air doesn't matter, so mods shouldn't matter also. Like you said, with all the other factors, weather and traction, the mods will just get lost in the wash. Mods just allow my engine to make more power, just like the denser air in New Jersey allows your car to make more power.

Ok, I have some Solo II (3 years not all that successfully competing in F Stock with an IROC Z28 350 and later with an LX 5.0) experience, I'm WAY outta practice though.

Why? Because if you came out here we'd be racing in the same air and I'm still stock, apples to apples.
I never said that denser air doesn't matter or that a low DA is not a good part of the reason why my car has run quicker (and I'm not done yet either btw ) than ALL others of it's type, I just don't think it's having quite the astronomical effects that some of you think it's having.
I'd be slower at your track for sure, the question is how much slower. Until I go there we will never know and NO correction factor on this planet is going to tell us either.

they could also race here and not be able to handle the extra power and and run slower

solo2 is nothing ive been ouy running the state police and town cops for fun for years. one year it was 48 state police cars painted on my fender

We can not trust any air that we can not see, here in Jersey

Tommy D

Yup, that is why time in the seat at your local track with a log book works so well

LS1LT1

Exactly, and by the same token we could potentially run as quick out there because the supposedly lower power our cars would be making might actually help us launch harder/maintain more traction throughout the run. Maybe they have tail winds more often. Maybe the track prep is better. Maybe my particular stock car's tune is better suited to a higher physical altitude/higher DA and wouldn't run much slower at all out there (highly unlikely of course)...this is why I don't believe that correction factors tell the whole story.

I installed a Vararam and hit the track again, this time with about 1100 miles on the car (some of us believe C6's get quicker after about 5000 miles).

CAI modified times for my 07 Z51 A6 are 12.61 @ 113.70 at Engishtown 10/21/06 w/Vararam, BFG DR's.

Temp was listed as 57*, BP as 29.75. Elevation of Old Bridge Airport next store is 87ft.

We race again 11/4, 11/11, 11/18 so I hope to see some even better times.

Marc (LS1LT1), it was very nice finally meeting you there, hope to see you again and talk some more.

LS1LT1

Nice meeting you too Joe, your car should definitely get quicker still as it learns the Vararam more and as the miles pile on. Might see ya at one those upcoming challenge events as well.

I wish I had a sea level track around. However, I think you may be right. I'm betting the torque management is hurting you more than me. It will be interesting to see what I run tomorrow night. If I get lucky, it may stay above 30 inches of mercury and down to the mid 60's. I'm hoping to break my personal best that I ran in my old 01 Z28 of 12.75 at 113.75. I ran the C6 at 12.83 at 112.3 two weeks ago in 84 degree weather with only a 29.68 barometer. I'll report back. However, some night if I get 55 degree weather and a high barometer, I may get down to the 12.5's. However, it's also tough to get traction when it's that cold out.

LS1LT1

Good luck man.

You're teasing us, you keep going to the track Marc, but aren't running your car. Get out there and break your own record!

You must be just like me, you're waiting for that perfect weather day to run! I've been doing just the same right now, I know my car will run 12.9s in perfect weather, but we've been getting a lot of high DA days here the last few weekends. I'm hoping Nov 5th is a good day, that's when I might give it a go. Luckily our local track is open for all four Sundays in November, so we should get some below sea level DA for sure (track is only at 600ft, and November high temps here are 35-40F)

LS1LT1

True LOL, and the last few times I've actually been to these various events in the Vette too, I usually go to spectate in the Z28 or with someone else.
It's coming though.

I have yet to run in anything lower than 2000' DA. I don't think a 2000' DA will make that much of a difference though track prep might. There was a local guy in So Cal who had a GT500 with the only mod for power being a tune. He dynoed around 475rwhp and ran a 12.8X@112.X at 4500-5000' DA or so at LACR. He recently moved back east and ran at a local track at sea level and good air. No changes were made to the car. He ran a 12.6x@120.x then threw on DR's for an 11.9@119. To me, 8 mph is big difference without adding any mods, power or suspension. The DA had to play a big part, even if the track was one of the "fast" ones.

LS1LT1

Again I do believe that air quality played a notable role in that improved trap speed, it had to.
But on the east coast runs this car also now had more miles on it, the driver also learned the car more, wind conditions might've been better (tail wind?) and one cannot ignore the role that 60 foots/330 foots play in trap speed. If he hooked better out in LA (which is probable because he was likely making less power in that higher DA) then his trap speed would potentially be lower than out east as well. So in effect that 8mph difference might not ALL be attributable to merely the better DA, too many other factors/variables.

bunk22

All those come into play but his 60-foot was worse by .2 with street tires and better by .2 with DR's. I've gone from a best 2.1 60-ft to a 2.4 in the same day and my mph dropped at most 2. Thought it might go up with a higher 60-ft but it didn't. Could have been a tail wind, he didn't mention it. Last time I ran the quarter, at least 20 mph right in the face, gusting to 30 mph. It was a factor no doubt.

glennhl

Thanks for wishing me luck, it worked! First run out of the box, CBFR and I were the first cars on the track, they had just sprayed VHT. I pulled by far my best 60 foot time of 1.94 (previous best was 1.99). Ran a 12.522 at 114.43. That's my best for these mods by .3 seconds and 2 mph. It was a good barometer of 30.1 and 73F out.

I finally felt TM tonight. Last run, it was 66F out and barometer was rising and up to 30.15. I spun hard coming out of the hole and when it shifted to 2nd (I have an A6), the car just laid down and quit. I had AH and TC off. The worst thing, is I saw the guy that tuned my 01 Z28 there (Nic) and he said he can't get rid of TM on the shifts on the A6.

LS1LT1

Congrats.

shurite44

Corrected times.

Oh boy, sometimes this forum cracks me up.

glennhl -

Nice run!!!

I really envy how the automatics, especially the A6s, come out of the hole. (1.9s are common with the A6s and A4/3.15s)

You trap speed is great for an automatic also.

What mods do you have exactly????

Good job,

Howard
