Impossible to achieve high 1.20s sixties

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.

Eighth times are 6.02 and 6.04 @113 on those passes.

You might be able to take a little first gear and slip the clutch some. It looks like you have plenty of engine to do what you want.
If you think you are exactly where you need to be to get to your goal maybe try leaving on the valve spring, that might get you there once. I tried it at Etown, not on purpose though. It made alot of noise and tighend up the clutch more then I wanted it, but it sounded cool. If that dont work leave in a different spot. Good luck

clutch, rpm, susp, tire.... Our 3300lbs sled cuts high 1.20s on a good track and low 1.30s on a greasy track...we took the car to one of the worst tracks in the country and cut a 1.27 by tuning,tuning, tuning...

I agree with Brad, first off stop the thing from rolling...

I like to stop with the tires at the edge of the water then stab the clutch before the tires grab and put excessive heat in the clutch. So I would recommend that as well as staging as shallow as possible. The other two biggest factors I see is that the wheelie bars appear to be slapping the ground at launch and unloading the rear-end and causing the tires to spin a lot more than I would want. The other thing is that the rear suspension doesn't appear to be separating and planting the tire. So I would try to keep the heat out of the clutch during the burnout, stage as shallow as possible with some break pressure to hold the car still, raise the wheelie bars so they aren't unloading the rear suspension and if that doesn't get you there see what you can do about getting the rear suspension to separate to help plant the tire then look at taking some clutch out of it if that doesn't get you there. Last but not least put a set of new M/T tires on it. Just my .02
