12.9 auto guys Im looking to see what your 1/8 mile time /mph and 1/4 mile time/mph were as well as your 60 ft.
im lookin mainly for ls1 automatics prefferably stock weight with longtubes exhuast and airlids only ..sounds random i know, but i need this info to tune my car, because i had these mods and now i have a stall and cant find my old times and the tuner wants to see these, so im going on the closet findings.
i ran 12.9 @ 110 with a 60' of 2.3 and dont remember my 1/8 mile info.

I ran consistantly 13.0s @ 106s when I had only longtubes/lid/true duals/2.73s. 60s : 2.0
Stall,3.42 and tune added, I ran 12.6-12.7 @ 108s. 60s: 1.8-1.9
LS6 intake/ 28.8 lbs inj and MT ET street later, I ran 12.2-12.3s @ 110s. 60: 1.7-1.9

cool i think this might be what i need, when i get home ill match up this info with my time slip. I also switched from true duals to a pacesetter off road y pipe, im thinking maybe thats where i lost my 5mph top end cuz that y pipe looks like it could be restrictive.
While I have quite a bit more I ran a 12.849 @ 107.77 in the 1/4
8.298 @ 87.074 in the 1/8 with mods in sig and UMI relocation brackets.....
I noticed a lot of cars trap higher than mine. I'm guessing me not having a tune and running rich might cause that

ya thats what im thinking, i know my o2 sensors are shot and my fuel economy dropped way low, its common to lose a couple mpgs with a stall sometimes but im getting 11-13mpgs driving normal, so im gonna fix my o2's and get it retuned..running rich can cause this loss of mphs .

I ran 12.99@ 108.5mph with a 60' of 2.07. My 1/8 mile was 8.4@86.8mph. At the time I had lt's, y, catback and a lid/ls6 intake. I only got one run in though and think I could have done better with some more seat time.

These timeslips above were taken the same season but different tracks. Bolt ons minus LS6 intake/MT ET streets.
These are my best runs w/ LS6 intake/MT ET streets.

hey raggedrides, i see in your sig that your y pipe bangs. Mine is bad also around 4-5k. Do you notice any performance loss when it bangs,like your getting knock retard when it bangs??? I feel like i can feel the car lose power when it does.
Loosen your Y-Pipe and adjust it, if that doesn't cure the banging, fix/replace your motor trans mounts

I was scared of it pulling timing in the beginning, but I don't think it's hurting anything. I ghetto rigged it with a piece of heater hose, which stopped the banging. After a few runs it'd come loose and start again. It ran consistent, regardless.
Like King said, I ought to loosen mine up and see if I can get it figured out.
