Cal trac /mono leaf results

@tubbedamx:
Thanks for the consideration:
track prep is good, they spray and drag before Pro and S/Pro each time. 85-100 Degrees cold or hot doesn't matter
Hoosiers D06 11.5W (13 1/2") 29.5X15
No Tubes
5 1/2" front travel, free no binding, Cal trac shocks all around
Transbrake. Have tried leaving at full on 5500,or 5000 chip, but right now 3700 chip seems to help, but still incosistant 60's
JW 8" $1200.00 5500 converter freshed 30 passes ago
Not scaled,weighs 3250 with me in it.Don't have access to scales.
Have not tried weight, but my friend put 150 LBS in his trunk and it seemed to help him. But he is a B body. Not against doing that.
12-14 LBS tire pressure. 14 LBS it was too loose going down the track,11 wades the tires. 13 seems best, I ran 12 with SS springs

Cal Trac. mono leafs
Rear shock mounts have been lengthened so that the shocks are close to centered.
They don't bottom out, or hit the end when extending. That was an issue I thought I had in the beginning, that they were bottoming out.
I stage and leave the same everytime.My lights are very consistant, so that tells me that part is fine.When I went to 3700 chip, I lost .020 in reaction time across the board, which is no problem in S/Pro
Bars are in bottom hole, with 1/16th clearance (no Preload)
Shocks on stiffest.
I started in top hole with no pre-load, and shocks on softest.
I talked to the super stock Dart guys at our divisional, and this is what worked for them.
I adjusted slowly to this point, making time trials till I got to this point, and this is as good as it gets.
We have pic after pic of rear tires. It hits the tires nice, then moves foward nice, then it just lifts up off the tire and it spins.
Depending on the spin or not, dictates what the 60' is. All the other increments are fine and equal.
That is why the Reaction times are consistant, because it leaves great every time. It is just the spin out after launch that is throwing everything off.
Hope I got it all.
