I hate to over simplify things but, jack the car up and spin the wheels by hand to see if you have a binding situation. Maybe you brakes are binding, wheel bearings etc.

I used to have to preload my 4-link to launch it properly. I put a antiroll bar in and I can launch the car with no preload in the bars, launches perfectly. Mine is a Chris Alston Bushing style bar. I would probably go with the Bears one or the Mark Williams pro bar. Its basically one floater axle w...

I agree with putting the PV on the front brakes. Just curious, what size of calipers are you using front and back?


Corey

If you were too far advanced and brought it to straight up by retarding it you will loose some bottom end but you will pick up some top end. I always install my cams 4 deg retarded in drag motors so yours should work really well.


Corey

It depends on if the cam was way to far advanced or retarded. Advancing will help bottom end, and retarding helps top end. What ever it was to start with, you will have reversed the effects by setting it straight up. I hope that all made sense.


Corey

1/2" ? cam timing is usually in Degrees. Try degreeing the cam and you will see how much it is (or was) off. How come you went with a gear drive? A chain setup is way easier.


Corey

2.893" and the 3.062" cases.


Corey

Just for future reference Mark Williams now makes a 35 spline spool that will fit in a small bore case.


Corey

Yeah, the reason I was asking is I have been running a Lenco for years but never have had a logger on the car. I am putting one on next season and would like to gain as much knowledge as possible to help reading the graphs.


Corey

Is it a Lenco planetary, or a gearbox like a Jerico?

Corey

Regarding StickShifter55's graph.

Being new to data logging, I am also curious as to why the graph has two peaks at every shift point. Is that due to the time it takes to put the clutch in complete the shift and release the clutch again? Or is there another reason?

Corey

The Moser and Strange nodular cases are getting so cheap to buy they are almost the same as OEM cases. They are build from a lot better material as well. I would investigate that option.


Corey

I built as set of jacks from the ones you use to level a trailer. They are screw jacks that have slip tube as well for changing to different heights. I just welded some jamb bolts on the tubes to prevent them from wobbling. Then you can dial in the car with the screw jacks a perfectly level situatio...

What are you sixty foot times doing, are they the same as well?


Corey

What kind of drive are you using? Chain drive , gear drive, what kind of front cover do you have?
