help me stop spinning My local track has little to no prep
My car so far
99 4th gen
FTI 3600 convertor
Long tubes &ORY
LS6 intake
Mickey thompson 275 50 15 on race star rims
Stock front suspension with sway bar removed
Rear koni s/a shocks near full stiff
Adjustable pan hard bar
Tubular lca
Founders bolt in lca re location brackets bottom hole
Weight 3340lbs
Front 1890lbs
Rear 1450lbs
Before I added the stall I would dead hook 1.99-2.02 60ft now all I do is smoke the tyres
I am going to the track tomorrow and wondered what I can do to help
All I really have to play with is tyre pressure lca mount points and shock extention damping

to fix the issue is probably going to be the right combo of suspension adjustments , I am not a suspension expert lol
until you get some suspension experts in here and having a track trip tomorrow I will give you a quick fix I came up with on the fly the one time I took my 3600 stalled bolt on car to the track , it was also on a street night with poor prep - I stuck my jack and toolbox in the trunk probably 120 pounds or so total and dropped the dr's to 13 psi ( re check after first pass as pressure will jump up after burnout) and it re gained traction 1.7 60's on the way to 12.1 @112. 1.7's is nothing to write home about but it sure beat 1.9's and got me from mid 12's to low 12's with only a handful of passes ever in the car.

Usually do quite a big burn out first pass then just a quick spin every pass after that
Currently tyres are at 18.5 psi
lca' in bottom hole
Rear shocks set half a turn back from full stiff (rebound is only adjustment)

I'm going to assume they are M/T 275/50/15 drag radials. I would go up on air pressure. My car at one point was very similar to your car. My car would spin at 20 psi, and spin worse the lower I would go. Found 21-23psi was sweet spot, any air psi higher of lower, it would spin. Recommended by Mickey Thompson always do a light burnout on a radial, too big of burnout and tires get greasy and don't work.

You need 20 in those tires, and if you don't have a double adjustable shock with radials you're fighting a long battl
If your local track's prep is sketchy all the time for whatever reason a radial tire may not be the best choice

I would question the track prep. Last time I was at the track I ran these toyo drag radials 275 40 17 street wheels. consistent 1.6s on street night prep with 4k stall and stock suspension. I cant imagine not being able to hook with 275 50 15. When I still had the mickey drs I had street nights where I would pull up with 32psi, no burnout and pull off 1.7s.
Might be kind of a dumb question but have you ever checked your motor and trans mounts? The only times I had issues hooking at the track was after I added a ss3600 a few years ago. I ran hoosier drs and the car wouldn't hook it was driving me nuts! Long story short, motor and trans mounts were demolished! I replaced motor, trans mounts, and for the hell of it torque arm mount. After that, the car hooked like a SOB.

First thanks for all the help
I have been to the track today and had some varied runs
I have run faster than ever before with a 12.70 @ 108 with a 1.9 60ft
And on that run it seemed to dead hook I had softened up the shocks and adjusted pressure to 16 psi
The track certainly wasn't running as fast as when I was last there but I hoped to get more than a tenth off of my 60ft with the convertor maybe I should have got a 4000 stall

I have zero problems pulling consistent 1.7 60' with my yank ss3600, Mt et streets on stock suspension with poor track prep

Tried a few methods but holding around 1000-1200 rpm and flashing it from there seemed to work best
The 1 time I flashed from idle I got a 2.6 60ft it was like a big smokey rolling burn out ran a 13.6

My old ss3600 gave me a best of 1.5. Usual was 1.6-1.7. That was all done on thin 275 40 17 drs on zr1 wheels. You should be doing about the same with that vig.
Maybe I'm overlooking something here but I think you're barking up the wrong tree by thinking it will get better with a higher stall. You need to look at your car man. I'm telling you, take a look at your mounts like I said. The same **** happened to me. At least you can rule them out ya know? But in anycase at this point, I believe there's a issue going on with your car.

I think you may be right about I am still on stock mounts and 165k miles
I wonder if my headers or y pipe are hitting causing false knock and pulling timing causing it to bog
It doesn't seem to ever bog on the street and feels like an animal but it was a bit disappointing how the launch didn't feel much better than before
I never data logged at the track but data log on the street has never shown knock

Also FWIW, back when I had the hooking issues I asked around on here and most thought it was crazy to blame mounts but I have the answer yes it does.
