Cars been down for over 2 years, finally got it out to a track rental.
3.4 Whipple on pump 85, 22psi dyno'd 720whp in Aug. Sra swap, no cooling mods as of yet, M/T 28X10.5 stiff wall slicks. Stock engine, full exhaust.

Two back to back passes.
1.50 60 foot 6.37 @113.70
1.42 60 foot 6.35 @113.20

Learned a lot that day, ARB getting installed and cleaning up my shifting.

Thank you all, I appreciate it. Front is a UPR K member. Front strange struts single adj with viking springs.
Rears are double adj viking coil overs, SRA swap. UPR adj control arms.
There's another tenth I believe in it the way it sits, then another tenth maybe a tad more with an ARB, that's going in soon. I'll keep posting the drag vids to my YT channel. Thank you guys)

What do you have your rebound and compression set at on both front and rear? Also what's your rear tire pressure? I have or HAD an identical setup to you and am getting very bad hop at launch and through 2nd. I say had because i now have a TRZ Motorsports ARB and Autofab Racecars LCA adjustable brackets with their heim joint LCA's. I'm also on 27 pounds through a 3.4. I haven't been out since the LCA & ARB were put on, actually it has a spool now too. Anyway BEFORE this my best was a 10.29 @ 141 with some awful hopping through 1st & 2nd gear.

I have the same coilovers as you actually. I'd LOVE to launch like yours. That things getting the tires off the ground and is moving out nicely. My rear springs were 185 i believe and i just went to 125's.

sorry for the overload lol, it's not everyday i run into someone with a very similar setup.

I'd say start in the middle with both of your adjustments and tweak form there as changes always happen.
I have 12-150 springs in the rear.
Tire psi this day was 12.
My launch rpm was too low my first pass, the car hooked for a second, then broke loose. I launched from 2500-4500 that day as the track changed.
Are you stock engine?

Yeah i tried to go 12" springs but the coilover nut is rubbing against the e-brake spring and if i go a little lower it'd touch the bolt head for the coilover bolt head for the bracket that mounts it to the housing. So i ordered a set of 10" 125's and also 150's. Seeing you're having some good success with those 150's i may throw those on first and try those out
