Thanks John! That is a big help! What type of shocks do you use? Varishock?John Wallace wrote: ↑Wed May 30, 2018 8:23 am Not sure on the spring rate.
It depends on some data on the suspension, around 200 lbs probably?
Try this link:
Spring Rate
I made many launches on my car to see where the bars needed to be for a good 'hook'.
(I have ladder bars though, 4 links lot more adjustments)
Some made a huge improvement in hooking. Then start on the springs, then the shocks.

Re: Critique 1/4 mile run
Summit had a sale on theirs when I bought them, made by Strange and saved $100 on the pair. I am running 95 lb springs.
The most important thing is to scale the car when you change.

a typical NHRA SuperStock SS/J Class Car will accelerate to these ET/MPH times :redliner wrote: ↑Wed May 29, 2019 7:02 pmThanks Max! It looks like ( as I knew) my bottom end lacks alot! What is your opinion ?maxracesoftware wrote: ↑Wed May 29, 2019 2:24 amCritique 1/4 mile run

0 0.0000 7.0462 1.6598
and your HP output is similar ,
however, your HP output after 1000 FT starts to fall-off as compared to a SS/J car
so i'd look for the cause of this .
you should be around 132+ MPH at 1320 FT ET Slip MPH,
and not just 131's
Re: Critique 1/4 mile run
THANKS! I see yer point! I am just sorting this combo and have only worked my way up to 35 degrees of timing which retards to 34 degrees. I will try bumping the timing up to 36/35 and see what happens, yer thoughts?maxracesoftware wrote: ↑Thu May 30, 2019 12:16 pma typical NHRA SuperStock SS/J Class Car will accelerate to these ET/MPH times :
