Ok so it was my first time at the track with this car and I've never driven a stalled auto. So I have a couple questions. I'm hoping for a 12.1 or 12.0 but I'm not sure if I'm expecting too much. I didn't foot brake and load the suspension, I just floored it and flashed the converter.
The DA was 1554 at the time I ran and I had the block off plate in my borla forcing it through my muffler. So do you think that if I take the plate out where it bypasses the muffler kind of like a cutout and the da was lower I could possibly see a 12.0? Also, should I brake torque it or just flash the converter? I dead hooked and I know my 60ft wasn't the best, but I think that's most due to me driving straight to the track and getting right in line without letting the car cool at all. Plus I only have 2.73 gears.
So with these things taken into account does this time sound right to you, or should it run better? I'm happy with it and was curious if I'm where I should be. Mods are tsp 233/239 cam, long tubes, ory, borla adj, lid, and ss3600 stall.
Honestly, I think if you take the plate out and the DA is 500 or lower you'll run high 11s. I have the same cat back exhaust as you. I had my tuner do a pull with the plate closed and I lost 10/15. I installed a QTP in place of the plate so I can open/close it at any time.
Try stalling it up to around 1500-1700, that's were I get my best 60's. I would take the cap off, when I run with my cutout open it's usually worth 1 tenth in general.
But mainly I would just worry about getting your 60' down and the rest will take care of its self. And there is plenty of room for your 60' to improve

Wow I didn't realize the plate made that big of a difference. I'll take the plate out and see what happens. I was going to for my first trip, but it was a last minute decision when I was out driving around. The da gets down sometimes in the negative numbers here so I should have a shot at it then. We are 411 above sea level here

Ok, I'll try stalling it out around there and playing with it a little. Going to be raining for the next 4 days but hopefully will go this Wednesday. As far as my 60' though, is there a way to get that down without getting gears? Because that's a horrible 60', I was honestly expecting a 1.7 as long as traction permitted. I dead hook right now with no wheel spin at all. I'm guessing if I stall it around 1500-1700 it will help my 60'? I'd like to break into the 11's if possible with the setup I have now with only adding gears.
if a car will dead hook with flashing it from idle I would stick with that but nothing wrong with trying stalling it up a bit either every car/setup likes different things. Open that exhaust and go on a day with better air like scotty is saying and you will be getting closer to 11's.

Do you know how to shallow stage?
No, what is it?
Also, would it make a difference on my pinion angle? It's set at 2.2 right now, would a 1.8-2.0 help it if there was any type of bind?

Ok, so basically shallow staging is easing up into the staging lights really slow. Stop when the first light comes on, and then inch up and stop as soon as the second light comes on? Also, since I'm dead hooking would it be better to do a little bit shorter burnout so maybe I could get just a little wheel spin, or just play with the rpms on my launch?

Yes that is how to stage, you just want to flicker the second light. And no, wheel spin will not help you.
You could add a little air to the backs till you have traction issues and I always fill my front tires to 42 psi at the track.
People say with a converter, gears don't help much.
But in my opinion they absolutely do help in the 60'

My rear tires I think had a little too much, they've worn in the middle a little. They were 22.5 cold and 25.5-26psi after my runs. But the fronts only had 32psi so I'll try adding air to them next time. I'm wanting to improve my 60' and with no wheel spin the only things I have left to try is taking that plate out of my exhaust, lower DA, staging shallow, and stalling the converter. So I'm really thinking about going to 3.42's and see if that will help. Didn't you say before that .1 off your 60' = .2 tenths off your et?
How bad of DA is 1554 at 411 at sea level. This spring the DA was in the negatives so I'm sure there will be a few below 500 left before it gets really hot. I've used the da calculator on dragtimes, but I don't know how accurate it is? What would running at a DA of say 700 vs 1554 do for my et?

In general 1500 ft DA is not horrible. Plenty on here run in a lot worse. Here in Minnesota the spring and fall d.a is around 250 ft. But in the summer it's 3000+ ft.
Yes, generally knocking a tenth off your 60' will in turn knock two tenths off your quarter.
As far as da's..... last year I ran a 12.69 with a DA of 3200
That fall I ran 12.40 with a DA of 250 ft. Absolutely no changes except the weather conditions

That's pretty good then picking up almost 3 tenths. I'll try the things everyone's mentioned on here and go back next week and try again. Hopefully with good air and everything I can get a 12.0. High 11's would be nice and maybe this fall it'll be possible with cooler temps.
I have never run an ls1 f body with 273's at the track , are you able to complete the pass in 2nd gear or shifting into 3rd ?
It shifts from 2nd to 3rd at 110mph so at my hp level it's not ideal really. I guess if I ran high 12's it would be good, or if I had another 100rwhp it would be good but I'm kind of stuck for now unless I swap gears. It comes alive around 125 though lol
3.73's would make a huge gain. Figure high 1.6 low 1.7 60' and a couple mph. That converter must be fallin back hard with the 2.73's. Also an SSRA or similar would be a nice cheap upgrade. What rear tires are u runnin?

Toyo TQ's and they dead hook when I flash the converter. Normally it starts out at about 4500 in first and then never falls below 5000rpm on shifts. I was looking at ssra last night actually. I was also thinking about taking the baffles out of my hood, but is there a way to seal it that way? Or would it even have the same affect as the ssra?
I hated my 2.73's at the track, shifting into 3rd just as you trap.
Couldn't agree more
Didn't you say before that you had already swapped gears before your converter? If not, then how much difference did they make with the converter? I've read where some people it didn't help them at all, and others say they gained .1-.2 tenths. I just want a better 60' and I would think that 3.42's would have to help that. I don't really want to go any higher than that because I already cant hook on the street with anything less than a 20 roll on concrete unless it's at least 85 degrees outside.

I would not even bother with that, Imo it is solely in your 60'
