Just wondering if any one can look at the interval times vs the time slip info and see if everything jives or if the car is falling somewhere.
Please disregard the first pass.

its been a while since I was running those numbers, but I remember my old Demon ran 10 teens at 132 or so. But it was a small tire deal and best 60 ft was a bout 1.42. I would say your 60 is very nice for the times you are running and the car is working great.

I guess I was just thinking that given the 1/8 mile times maybe it was losing something after that.
I know I need to do something with the 4 link and perhaps add a rear sway bar to level it out but my focus on TnT nights has been with the girls cars. Sometimes I don;t even get to make a single pass with mine.
Maybe I just need a track rental with someone that knows how to set up a chassis

60 Foot 1.40 330 Foot 4.05 660 Foot 6.36 660 MPH 106.91 1000 Foot 8.36 1/4 Mile ET 10.08 1/4 Mile MPH 131.5 These are the idea increments for a 131.5 mph run. Looks pretty close to what you are doing.

24mph back half isnt out of the ordinary for a 10.00-10.30 ish car. A car as lite as yours I'd expect maybe 25-26mph, but your not out of the realm of reality at all. 27mph back half is a strong pulling car, or a bigger motor.When you see 27 mph on the back, its typically a 500" or larger motor. I'd say overall its pretty noraml, and not knowing your camshaft, gear and converter, I'd not be too concerned with it. Your incrementals show a failry consistent shift point. The 60' is a significant variance, but not knowing the track conditions, and weather, it may be nothing at all.

Bill MOST of your issue is the 60'... could be a multiple of weather, track or both... the 330 tends to follow the 60'... I would like to see a 25 mph spread from the front to back half but yours is close... have you tried jetting.. could be a touch lean

Here's the same log book W/ the weather data....
Here's the times each run was made.
run #2 @ 11:36 PM fri night
All the rest on Sat
Run #3 @ 11:26 AM
Run #4 @ 04:02 PM
Run #5 @ 07:27 PM
Run #6 @ 10:01 PM
Run #7@ 11:02 PM
I know have issues to work out in getting the car to leave based on the last post I made and the videos it looks like it's coming up harder on the left and unloading the tires a little just after the install hook.
I have not as of yet had a chance to make any chassis or jetting changes. Paying to much attention to the girls cars I suppose and ignoring my own.
