I'm not sure of DA or the hydraulics. My shifting
Was good and smooth. I wasn't WOT shifting but shifting quick. As far as the run went, my fastest pass was 25psi tire pressure and the shocks were pretty soft. I drive around the burnout out box, spun the tires clean, staged, around 2500 rpms I would slip the clutch some the go WOT, shift at 6000-6200. Then pass the quarter and shut down.

That is part of your problem, but , probably not all of it. That cam will need to be shifted around 6800 if not a little higher to maximize it.

Looks similar to what my old car ran cam only with a 231/232 .612/.588 111+4 cam in it. Put down 387 RWHP on the dyno, which doesn't mean much, and it ran a best of 12.9 @ 113 with a horrible 60'. It trapped between 110-113 depending on the launch on bald Sumitomo street tires. I never thought my car ran right compared to other cam only set ups at the track but it held it's own on the street from a roll. The tune left little to be desired for me as well I know, but I never had it re-tuned or changed anything before I sold it.
I would start by getting your tune looked at to make sure it's good and see where the limiter is set, and try shifting that thing higher as previously suggested.

Alright thanks. I'll look into it

Not sure on raceweight. Car is a 02 Z28 M6 ttop car with no spare tire and a 160 pound driver. I think a mixture of the DA and my low shifting RPM is where i lost my trap

Trap speed seems right to me considering the circumstances. That cam requires higher shift points plus if you are wheel hopping into 2nd, that is hurting your momentum. Sort out your traction issues and your trap speed should increase considerably.

My thoughts:
--2.2 short time you will drop 3-4 tenths if you can get that to a high 1.9.
--QA1's front and rear? Keep the butt down and the nose high. I'd run the rear's a little softer than 50/50 and run the fronts a little stiffer than 50/50.
--Shift higher as noted. Trap speeds are low for the mods, would expect 114. Try 6500, 6700... You might need a tach or a shift light to become more consistent. I bet you are shifting like at 5800.
--ET and trap speed are two different issues for you. Try to fix 1-2 things per pass but don't do 3-4.

Made it to O'Reilly Raceway Park yesterday for the opening day of test and tune and wasn't satisfied. The car is a 2002 M6 Z28. MS3 Cam/Valvetrain Upgrades, Long Tubes, ORY, Borla, pro5.0, spec 3+, 4.10 10 bolt with a girdle, 3pt subframe connectors, poly ta mount, control arms, strut tower bar, 12 way QA1's, on BFG G-Sport street tires. I got 3 runs in and below are the times
................Run 1..............Run 2..............Run 3
60ft..........2.218..............2.454............ ..2.242
330ft.........6.091.............6.215............. ..6.013
1/8............9.120............. 9.124.............. 8.955
1/8 mph......83.06.............85.37............... 84.76
1000ft........11.634............11.578............ 11.428
1/4............13.711............13.620............. 13.485
1/4 mph......109.18............110.66.............109. 94
What do you guys think? I was rolling into 1st not dumping the clutch and It was wheel hoping pretty bad in 1st and very bad in 2nd. I know its on street tires but i was hoping to do better than that. Anything i could do with my current setup to get better ETs?

I was expecting way more from it. BUT, my car does not have a tune yet...

my car with a lid and muffler trapped identical to yours, a few passes just a touch more. same track, roughly the same da, i think it was closer to 25-2700' the days i was out there. i'd guess you're not revving it high enough. any dyno sheets with the caR?

OP, I agree w/ most of the replies,
1) Get a good Torque Arm
2) Get some DR's
3) Get a dyno tune w/ that to see where ur max h.p./torque is at, to figure out when to shift
good luck with the 10 bolt rear..keep us advised

Were you the Camaro with the paper plate on it?
I was stagged next to you. Black third gen with draglites.
Check and make sure you are indeed getting wot at your throttle body. The first Wednesday tnt I was at I was only getting 1/2 throttle due to throttle cable issues. Went out and picked up 1.2 sec. And over 15mph. I know it sounds stupid but seeing that you just bought the car you never know what someone else fugged up. Lol
