Good day at the track

Hi 70dart499
Here is a little trick I do with my delay box, and the full tree leaving off the top bulb.Instead of drilling the tree like a Pro tree the minute I see yellow, I relax, and put more delay in my box. I leave as I see the top bulb come on fully.
My last car with my engine tranny combo,was a Super Gas 2200# Daytona. It would go red on a 4 teenths Pro tree, I had to put .015 to not go red. So now it is a little different with a heavier car, and leaf springs.
My buddy with his tube chassis Cuda, always drills the tree and has good .005 lights, but he red lights a lot.I use to put 1.050-1.080 in my box (even in my old back half Duster), I now run 1.020. I have had no red lights this year (not saying I won't).All my losses have been break outs ( 2-3 hund.) from lack of data on the new car.( I am really learning fast how to drive the finish line backing into people).
A friend told me once, if you set up for .019 lights, you'll be good.Mine have all been
.011-.017 except for when I ran this sitting duck, I put .010 in to not go red. My light was .023 which would have been .013.
In the later rounds when it starts getting dark, I have gone .002 & .004 green.
Hope this helps, and I don't mean to sound like I am gloating,it just seems to work for me.
By the way, you know what they call us top bulb racers don't you? People that can't bottom bulb race! LOL
