Suspension help needed, settings to get into the 10's
Here is my Combo
94 Z
383 Solid roller LT1
4L60E, 4300 converter
4.11 gear
325/50 drag radial
465 rwhp, 436 tq
Spohn tq arm
BMR K member
First generation HAL QA1's up front
Koni Double adjustables in the rear
Stock rear swaybar, no front swaybar
Airbag in RR spring
Raceweight 3780 lbs
The car has only been to the track once, best was ....
60 ft 1.58
1/8 7.15@95
1/4 11.25@120
I only got 5 passes in
Settings on that pass were
Rear tires 12 psi
Front shocks loose as possible
rear shocks as installed(neutral)
airbag empty
Leaving at 2000 rpms flashing converter.
The track was crappy when I ran that ET.
I think I should have a tenth or so to get out of 60ft, where should I start on rear shock settings? I have KONI double adjustables on the rear.
Thanks
David

Bryan, part number 8242-1006SP1, I know you are gonna nail me on those shocks, but I got em and gonna have to work with them. Afco's are kinda out at the moment.
Don't you think this car should 60 ft in the high 1.40's?

I'd guess around 1.47-1.48 60ft with a 10.90's et. You should take a video of the car at the track so we can all see how it is leaving.
BTW why run an airbag empty?

I weighed the car on 4 corner scales, this is with a full tank of fuel and 15 psi in the right rear airbag.
No driver
LF RF
992 881
LR RR
743 854
With driver
LF RF
1099 913
LR RR
880 900
Thoughts?
Bryan, BTW, I have BFG 325/50 drag radials, can I rotate them side to side? There is no rotation arrow on the tire.

Wonder why your car is so much lighter on the right front???
I scaled another car I had and it was only 5-10 different from one side to the other, you have a big *** hidden turbo on the side

I try different things, I have not adjusted pinion angle, it is at -1* because all of my rear is heim ended, nothing moves really.
I tightened the rear shocks to full firm on compression, didnt really effect it much.
I can get it down to consistent 1.58's, everything I try from there either makes it worse or has no effect at all.

4300 stall??? It isn't flashing very hard. What are you doing when you stage it??
Looks like you aren't pre-loading the chassis much, ever think about trying a 2 step hooked up to the brake so you can have it floored and then as soon as you let off you have full throttle?
Do you have adjustable lower control arm brackets?
What are the front and rear shocks set at?
