i'm guessing you were on stock tires, rest of the car bone stock? what psi and rpm did u launch at? what was temp/alt? 
'08 E.t. 12.45 @ 114.97
'08 E.t. 12.45 @ 114.97 I believe this is the first official private '08 run for a C6
e.t. 12.45
mph 114.97
60ft 2.025
I got 9 runs in and the slowest being 12.635 @ 113.23 with a 2.022

That's cookin pretty good in this heat.
Did you try removing the fuse so the butterflies are open at launch? Is yours a Z51 automatic? Reason I ask is to see if you have the 220 tread wear tires or the 300?
I'm going to take mine out tonight and see if I can run better than a 13! LOL! I have the base lLT with the 300 tread wear. Might have a traction problem but mph should give some potential indication.

This car is a A6 2.56 300 tw tires with the 3LT package. It was consistently around 200 deg. during the runs. I had 9 passes worst being 12.63 @ 113.6. It did not have the NPP exhaust. Tires seemed to hook better at 23 psi and I got better e.t.'s when launching off of stall (1400). Flashing would only result in a good amount of wheel spin. Reality the 60 ft wouldn't change just my et. I really hope you get to run your car tonight. I only had 517 miles on the clock. I literally felt more power with every run. Some were flat out hot laps and each one quicker. These cars can take a beating.

I'm happy for the people that waited until '08 to pick up their C6 but to be perfectly honest I feel a bit robbed. I cant believe the LS2 only lasted 3 years where as the LS1 lasted 9 years. The only thing I can do now is keep modding.lol

With this tight converter and TM it took me 1.968 seconds to get from launch to peak torque of 4400 rpm. Lot of wasted time.
Traction was good. No detectable problem there. 3360# race weight.
Track was so crowded all I got was two passes. Might mention the first pass was a 12.80 @ 113.16 mph. IAT was 131* on that pass. Max. timing I recorded that pass was 22.5*. 16-18* or so at launch.
Congratulation Larry! I was definately cooling the intake. Two bags across the intake bridge during cool downs, I also didn't have to wait in line, cause the track was basically open for me to do my runs. Great timing info. What were your 60 fts?
Thoise are some good times with more to be had. Would like to see what the cars can do with some traction and cooler temps. The 08 vettes should be close to the C5 Z06's in times and speed wise.

Icing the intake and not having to wait idling is going to greatly help ET with these cars. With stock tuning IAT temp is really a factor. Right now I don't know how much of the IAT timing retard can be removed without getting knock retard. I have some testing to do. I'm sure some can go. Maybe just zero the table and see what happens!
My 60' was a 2.010. Really can't believe it was that good considering the heat, my IAT temp and this TM.
TM is another issue for both of us. As I was brake stalling at the line around 1100 rpm advance was reading 31*. Immediately when I punched it to 100% throttle position the timing went negative to around -2* and slowly rose to 20* taking .656 seconds. That 16-18 was a little farther out. I thought maybe the negative numbers were bogus but maybe not so. More than 1/2 second into the pass before the engine is making decent hp. We know how much a tenth in 60' equals to 1/4 mile et. At each shift advance drops into the negative advance range.
To reach our peak torque of 4400 rpm it took 1.969 seconds from launch. With the right converter and eliminated TM that should happen within a couple tenths or less.
Did your car shift into 4th during the run, Based on some calculations the 2.73 was supposed to shift into 4th but nobody has tested the theory. I think you will have to agree with me that these cars with traction, more miles and seat time they will see 11's by winter, and quite possibly without a tune.

On the first pass in D the tranny stayed in 3rd all the way just past the lights when I let up. On the second pass in S it tried to shift to 4th just before the lights. Probably why the lesser mph. Shifts are really lazy on this car. For some reason my mph in my log read 116 mph on the last frame, on the first pass and 117. I let up at or just past the lights. Don't know why my log reads so much more mph than the time slip. The program has the 3-4 shift at 99 mph. Apparently rpm is governing at 6300.
Larry, this is Ponchorello from the corvette forum. I own the blue lemans c6....i was supposed to make it out last night but had to change my plans.
If you want some clean runs, you should try on sunday. Its usually pretty dead and you can get 10+ runs in if you wanted.
I will be there tomorrow to get some runs in.

Sundays is better but this Sunday and today I believe they are having the Junior Dragester races. They are what took so long last night.
