I'll list my setup 1st:
Drag springs
Non-Adj drag shocks up front
10 way Adj Strange shocks in rear
UPR rear upper & lower control arms
no front sway
3.73 gears
26"x11.5" ET Street radial slicks
2500 stall
C4

I've adjusted the shocks from soft to stiff & nothing seems to change much. I've had the slicks at 18-14.5 psi and just about the same results. I've launched off the converter & off idle. Can't get traction either way.

I have made passes on motor & on spray. The juice is setup on a WOT switch. The run that I went WOT right off the bat I got a 1.8 60'. That is the best 60' I have been able to get w/this car so far. Only two 1.8s. The rest have been from 1.9 to 2.1.

I know the gears don't help traction, but the car, not w/me driving, has cut much better 60's.

Should I try running less air in the tires? If so, how low should I go?

 

Are you heating them properly?

 

What is the pinion angle? Try 15 psi in the slicks and work down in 2 psi incriments (stay abouve 12 is the rims are not screwed and you your not running tubes). Is the car actually spinning? With 1.9-2.0 and only a 1.8 on the can it does not sound to me like the car is spinning, but I would want to know either way.

 

I do long burnouts

 

I don't know.

I have tried 15 & best 60' was 1.9.


The car was obviously spinning on some. It didn't feel like it spun on the 1.8 run, but I didn't have anyone there with me to tell me for sure.

 

How are you launching? and were other cars having issues as well or was it just you. With slicks a 2.0 is either REALLY bad spin or a bog. 2500 is a pretty low stall so that's not really helping you, unless you are spraying it out of the hole.

 

I was going off idle. There was a 5 speed fox on juice on ET drags cutting 1.6s.

I sprayed out of the hole on the 1.8 run off idle.
