Track Results
I just got home from the track. DA 2986....80 degrees, 89% humidity.
Right off the trailer first pass ever with this combo this was the best pass of the night:
1.629 60 ft
4.775 330ft
7.446 1/8th
91.80 mph
The track started sweating (from a rain earlier today) and became pretty worthless
The rest of the Night I ran consistant 7.50s with a high 1.7 60 ft. I couldnt get the car to hook for anything was was spining through 1st and part of 2nd most passes.
These were on 26x10.5/15 hoosier qtp tires with 12psi on a 10"wide draglite. Any thing higher I was blowing through 1st and 2nd.
I know there's more left in this setup. The car has 100% stock suspension and even has the front sway bar. Can someone point me in the right direction to get this thing to hook up?
I was thinking:
LCA relocation brackets
comp 3 way adj shocks
boxed lower control arm
I have an adj. BMR Torque arm thats not installed as well.
My mph seems kinda low, I need to figure converter slip. I was going through the traps at about 5600-5800 rpm around 92mph

Get those suspension pieces installed and you will be happy. I love how my Comp Drag Shocks unload on even the middle setting between street and strip. Figure out the slippage and you will be very happy. You need to start donating LT1 stuff to now my dad's car
I would skip the relocation brackets. Disconnect the front sway bar. Competition Engineering shocks on 50/50 and an air bag with 15-25 psi would be a good place to start (and inexpensive!).
Anything that can help this thing hook up that doesnt cost an arm and a leg
Thanks Marc
I talked to ATI on the slippage. They said that that type of slippage in the 1/8th is normal, it doesnt lock up and become effiecient till later in the run.
Looks like Ill have to go to the 1/4 to see what it actually is!

Do some experimenting at the track. I've posted this before but i'll repeat it again.
Make 2 back-to-back passes with you launching the car off of an idle. Be as consistent as you can with the shifting (unless you leave it in "D"). Hopefully the slips will be within a few hundreds of each other.
Then make 2 passes with you pre-loading the converter to a much higher rpm without pushing through the brakes. Basically take it to a point where you really have to hold the car hard with the brakes. Typically this can be from 3000-3500rpm. You'd be surprised at what MIGHT happen. My car will ET about a full tenth better (in the 1/8th) when I load the converter. You are also loading the suspension a bit when you do this. The car will feel softer on the launch because there won't be a huge flash of rpm, but it MIGHT perform better by trying it like this.

I love how people claim auto's are killing their mph by huge amounts to justify their track times. Auto's don't hurt 1/8th traps nearly as much as they hurt 1/4 trap speeds. I did a t56 swap in my car and I only gained 3mph in the 1/4 over my slipping 4l60e that was hitting the limiter before shifts and shifting well past where my cam was getting valve float. If the tranny wasn't slipping I'm sure it would have been a very marginal gain in mph if any at all. A claim of picking up 3-5mph in the 1/8th with a simple tranny swap is laughable.

I love how everyone ignores facts to try to make their arguments look better 
I went from 12.56 @ 111 to 12.49 @ 114 with the tranny swap. I guess that's a pretty amazing feat in a full weight car since I was supposedly only making 305hp though. You just know all the facts huh? I didn't realize mid 12's was low 13's. So gaining 3mph from a slipping tranny that was hitting the limiter over 500rpm's higher than the shift point is considered a good gain? If I put in a built 4l60e I probably would have gained the same.

I guess that's a pretty amazing feat in a full weight car since I was supposedly only making 305hp though. The ONLY change I did was I took out a slipping 4l60e and put in a t56 and I gained 3mph. With that cam and springs I was getting valve float at 6k and it was shifting at 6500 on the limiter. Shift points were supposed to be 5800, But I guess the slipping part is irrelevant and had no impact at all on what my car ran or trapped?
Do you have any experience with a 4l60e to t56 swap yourself or are you just throwing random #'s out there like usual? This is just like the auto guys posted locked dyno #'s and claiming they will gain 50hp with a 6-speed.
Feel free to take this to PM's if you want to continue since I won't be posting in here anymore taking the thread off topic.
To the OP good luck figuring out bugs and ironing out the car.
Went to a 1/4 mile track saturday day.
DA was 3401
1.625 60ft
7.45 1/8th @91
11.71 @115.5
MPH is still low, ET IMO isnt where it needs to be. But the weather isnt Ideal to put down great ETs with that DA.
There's a couple things Im going to try to see if I can pick up some.
My catback was crimped right behind my Y-pipe by my exhaust shop to make it fit it and it cut down a 3" pipe to 2 3/4 in a 2 spots. Im going to cut that area out and install a cutout.
Im also Going to instal an ls lid setup, Hopefully Ill see some gain out of it.

Follow his advice. The comp or summit shocks are cheap, same with the airbag. Than install your TQ arm, the 60fts should really improve once you get things dialed in.
If you want to add the lid for more HP go for it, but I would get the suspension dialed in first. But thats just my .02

Here is what dragtimes says you altitude corrected times would be at a sealevel track on a decent air nite. Straight from drag times.com.
Stock and Mildly Modified Naturally Aspirated Engines
11.226 @ 120.564 MPH
Now listen and pull the swaybar bolt at the track and try a $30 airbag to help your 60' and will in turn make more mph. Once the weather gets good it's going to run much quicker but you have to keep at it. later Clint

Clint this was with out the front sway bar. Where can I get the drag bag for $30?
No doubt. Im working on the suspension as well, Im picking up the air bags tmrw or weds, Putting in my torque arm. The Comp shocks will have to wait just a bit.
The cutout is cheap, and the LID setup is the right price as well.
There's just so much to do. It will take a bit. But hopefully I can get it closer to where it should be.

Yeah that was with the front sway bar off of the car. I think When I get the drag bag in and get it to come off the line straight as gizmo and clint said I should see a decent improvement in times
Its just tough to spend 80 bucks on bags when I only need one lol

I do think the ET and MPH is a bit off but you are getting so close. Only a few more kinks and some better air and I see LOW 11's in your future!
i put some qa1's all around on mine and i just tighten up the back all the way(if the track is good). the shocks droped me about a tenth in the 1/8.
