He (my brother) won 2 times Ls3.
We planned on racing 5 times but he refused.
I quess he wanted to go away with a win (2 outta 3) rather than take a chance and lose best outta 5.

It sounded like a close race all three times. But the question is, how did you (LS2) beat your brother (LS3) just that one time? Did your brother make an adjustment after you beat him that one time? We know that the LS3 is faster, but by how much?

honestly, it sounds to me, they both don't know what they are doing......... to run a C6, you need to turn Trac OFF, not run in Comp mode

Well this kinda proves that a stock ls2 will get walked from a roll by a stock ls3.
If the ls2 was intake, header, tune at 370 ish whp, the new ls3 auto is dynoing right at 370 whp as well.
SO if they were neck and neck it says that the ls2 needs at least those mods to keep up. At least that is what I am getting out of this.

You guys raced with traction control on? What the heck.
I raced last sat on stock runflats with a stock car and was able to pull some high 2.0 60s and I had to go through the water box at this particular track. I think you guys both need to have some more experience under your belt.
These races dont really tell much

Okay i went to the track last wednesday and met up with 2 friends of mine one has a stock LS2 A6 that ran a best of 13.00@109 and the other has a new stock LS3 A6 that went 12.46@116 and later installed a new K/N filter only and went a new best of 12.38@117 so there is quite a difference between them mainly on the big end!

I am expecting a stock LS3 Corvette to break into the 11s once it gets a bit cooler.
BUT
It would be interesting to actually see what a stock A6 LS3 vs stock A6LS2 does at the track and to keep it interesting launch both cars with everything off from an idle with the same amount of air in the rear tires.

Where the hell are the time slips for these runs? Then we can see reaction time and 60'. "5 car lengths, then 5 car lengths the other way" What the hell? I've messed up and spun through first (who hasn't), but it costs 2-3 tenths at most. Maybe 3 car lenths.
And yeah, TC off on the drag strip. (Keep AH on, I don't think it costs anything ET wise and it's good insurance).
Thanks High Roller1, that actually sounds like helpful information. I can't wait till an '08 shows up at Firebird. Sounds like the LS3 isn't as susceptible to heat as the LS2. LS3 was matching the mags trap speeds, LS2 is under by a good 4-5 mph. 7 mph difference is insane. If only my '05 didn't depreciate so much in the past two years, it'd be worth upgrading.
There was a new 'vert on the way home from work today but I was in the Protege. He had the NPP. First 08 I've seen on the streets actually. The driver was really old, and didn't want to play.

I agree that some A6 cars do run 12's but on that night at the same day,same track those were the results and there also was another bone stock C6 A4 car there running 13.20's every pass. The LS3 is very strong car stock!
