'67 El Camino H/SA

[HandOverFist]

A recent operator error revealed something of interest I had not considered. At a local TNT session my first pass was a beast off the line...not so good down track. By beast I mean my 60' times went from it's usual 1.61 to a stellar 1.50...launching hard and jerking the front wheels 2' off the ground. The et's and mph were not reflecting what was happening on the starting line however.

It was not until I returned home that I discovered that somehow my locked timing was at nearly 50 degrees advanced. It did not like it at the end of the track, but boy howdy did it love the timing at launch.

With the programmable 6AL I have installed I was able to plot a timing curve which will allow 48 degrees until 5000rpm and then begin pulling timing out thereafter down to 36 degrees. I have yet to test this and no idea if it will pan out.



If anyone here sees a problem with this experiment I would be happy listen to the pros/cons.
