Dyno comparisons are open to interpretation, nobody knows if the dyno is set correctly, operated correctly or reported correctly. Smoothing of Zero can inflate peak HP and TQ by as much as 15 HP or 15 TQ over Smoothing 6. If everybody could run on the same dyno with the same operater at the same time AND have a neutral 3rd party compile the results maybe comparisons might mean something.
I'm happy with my results and with the price I paid for the products I bought. But I still need a tune to balance A/F ratios and timing.

I didn't get a dyno yet but an interesting observation from my cam install this weekend.....I gained more from the cam than every other mod put together so far; debating air cleaner results seems silly at that point.
All summed up; I don't get the purpose of more than 500 rwhp when without nitrous, I have no traction in the first two gears. Literally from a roll in second and not popping the clutch, the car breaks loose just rolling into the throttle(BFG 295's in the rear). What the hell do all these guys with 600rwhp do on street tires if yu want decent handling. I can't imagne being outside the 450-460 rwhp range at this point.
Forget the 400 dollar air cleaners and just spring for a cam/springs.

It seems like the LS2 responds really well to heads/cam/headers in comparison to the LS6. I don't know of many LS6 cars pulling 450+rwhp and I have seen a few LS2's that have hit 480+!!! Pretty amazing! What kind of 1/4 mile times has everyone pulled stock? Again please mention if your times are with an auto or a stick. My best on the stock tires was a 13.2 then I switched to my 16" rims with a garbage BFG drag radial (well over 100 passes on them) and pulled off a 12.7! 6 speed car non Z-51!

Done just today at 75* F
MN6 Z51
Bone stock down to the paper filter 2600 miles on the clock.
SAE corrected, smoothing factor 5
339.8 RWHP / 337.3 RWTQ
Seems that it's where it is supposed to be as advertised.
Nice flat torque curve, at and above 300 ft/lbs from 2100 RPM all the way up to 5900 RPM.
Oh, and BTW.........I have yet to break 13.6 in the quarter mile with it.
I routinely see 2.3second 60 ft times, and had a "best" of 2.55 my last run which produced a 13.7.
Hows my driving?
FWIW my modded A4 C5 was making 327.9 RWHP/ 341.3 RWTQ on the same dyno before I traded the car. . It would run 12.3s with 1.8sec 60s on BFG drag radials.
Sorry for the length.

Just made it by a hair
Run # 1
30 lbs air in rear tires
67 degrees F Absolute Barometer 29.31
60 foot 2.078
330 5.602
1/8 8.464
mph 1/8 86.88
1000 10.906
1/4 12.992
MPH 107.42
Run # 2
30 lbs air in rear tires
64 degrees F Absolute Barometer 29.47
60 foot 2.107
330 5.603
1/8 8.439
mph 1/8 87.65
1000 10.855
1/4 12.922
MPH 108.39
Quite a few cars broke so we were waiting most of the night. We were prepared to reduce the rear tire pressure to 26lbs for the third run but ran out of time.
The traction system was completely off for both runs. The first run the tires spun quite a bit and the first to second shift was ok but third seemed to be flat.
The second run, the car really spun the tires and sort of bogged. It has never done this before
(TM rearing its ugly head). The colder air accounted for the better second run. I'm thinking of going once more before I do any mods. We spoke to several other guys with C6, six speeds and most of them were running slower than me

Congrats!
But, we both know you can do even better.
(I sound like your parents)
I think if you lower the tire pressure to 26# a 1.96 60' is possible, that would make your 12.92 run a 12.82.
Also, I did a quick calculation, you are right, your car is falling flat on the top end a bit, if your 1/8 is 87.65 you should trap 109.56 in the 1/4.
On your 1st run 1/8 of 86.88 you should have trapped at 108.60.
So there is more ET to be gained and some time to be shaved.
My bet, next time is 12.77-12.82@109-110.
I go on 11/11 to ATCO for a Track Rental - I am hoping for high 12s myself. My set-up is just like yours - base susp, 3.15, A4, but mine is a Vert. I also have no other options, so the increased weight of the Vert should be balanced out.
How did you turn Traction Control off?
Did you use Competition Driving Mode (2 presses) or did you hold the Button in for 10 seconds to where it said TC off AH off on the DIC???
Thanks and GREAT JOB on 12s 1st time out,
Howard

EB20003 I was having the same problem with terrible 2.3x 60' times and running 13.2's! Then I finally found that if I launch the car at 3000 rpm but slip the clutch....very little tire spin and no wheel hop. Finally, I found her sweet spot with a 1.9 60' time on the stock tires. I ran a 12.8 on the stock tires. There is a very fine line between the tires going up in smoke and wheel hopping.

Congrats on the time Tommy.
@ShockerRacing, thanks for your suggestion. And yeah, I know you are right and it will take a bit of practice to launch this thing on street tires.
But I am having a blast.
Though I have yet to break 13 seconds in this car, believe it or not, it is a lot more fun to drive than my last one.
That one was stab,steer, pick up a 12 second time slip. . This one actually requires some thought in order to produce a good ET.
But I am not going to blame my terrible times on my car. The dyno proves that its not the car,...... its this pathetic driver Give me a few more passes and I 'll get it right

Hey Howard,
Thank you, actually it was the second time out. In August we ran at the Corvette show it went 13.20 & 106
on a very hot & humid day.
When you start the car to leave the staging lane press and hold the button, the DIC will say traction system off. You will be good to go!
I left at an idle and did not manually shift the automatic. We are planning to go at least twice more to sort out what this car likes. Next time out we will try lower tire pressures. After that we wil try manual shifting and then a different launch.
I'll keep you updated how my car runs so that we can compare notes as most of the guys at the tack have six speeds. The only other guy who I met that has a auto has a C5 with a supercharger.

Don't be so quick to blame yourself. There are was a guy at the track who had a six speed car with several mods that runs in the mid thirteens. In addition, he has broken driveline parts
You just need more seat time and have to sort out what the car likes.
