Impossible to achieve high 1.20s sixties
 
For crying out loud.....what is it going to take to get me into the high 1.20s? Stuck in the low to mid 1.30s. I feel like I should be able to get consistantly in the 1.20s , but no luck.
Leaf springs and floaters / ladders is the current setup.
Is a 4 link the only way?
Realize , its a manual trans...........

1. what's your best 60 foot to date in what weather and at what track?

2. are you dead hooking or turning the tire on the launch?

3. need to know EVERY detail of the car/combo, from front to back, top to bottom including.

I've seen .04 or more difference in 60' times just because of differences in the timing systems and rollout from one track to another. Don't get too stuck on numbers. It's all relative.

Ed , thats a headfull of questions....the short answers are:
1.30 ( 1.33 avg ) at Reynolds and Commerce.
Tough for me to answer 2 , watch video , you be the judge :

You already know most of the other "details".
This could be a clutch tuning issue , but I'm beginning to think a 4 link is the only way to achieve the kind of 60s I'm after.......

Chassis tuning should be different for an automatic / converter application , I'm assuming through the way they apply power ,but I'm not sure.
It may just come down to the old leaf suspension I have ( with floaters of course ). The shocks are Afco double adjustables rear , singles / front.
Understand I've had a variety of shocks and I.C. ride height changes but no "brass ring ".

Joe, call me when you run another 1.30 and I'll get you a 1.29.:)

In your mind does that get you the brass ring or are you wanting a 1.20's every pass regardless of weather/track conditions?

It may be there but without in depth review of your car/combo, it';s all just a guess.

I would consider a range from a 1.26 or so to a 1.30 to be acceptable.
On every pass.........
It would be nice to get some SS stick guys to reply as well.......in particular the SS/B thru F cars

good luck with that request.

Anyway if you want me to critique your combo give me a call.

Set the car in the lights with the line loc. If the car is rolling that is not helping you at all. Sounds like you are sledgehammering the clutch on the leave and the gearshift. a stickshift normally doesn't 60ft like an automatic no matter what you do. Our ET picks up after the 330 on. Looks like your shifting that car 5 ft before the 60 ft clock. You may have a little to much 1st gear in it to acomplish what you are looking to do. What ET are you running? what kind of 8th time and MPH are you running. That car looks like fun to drive.

Those 2 passes were a 9.51 and 9.53 back to back.......regardless , no matter WHAT I've done in the past it wont sixty like I want.......at 3000lbs and leaf springs I'm beginning to think thats about where it ends........
also at a 3.05 low and 5.86 I would think the gears are pretty close.
