No box race any dial in. Full .500 tree. No delay boxes allowed in car.
What do you mean by the faster car will win with dial in?
Back in the 70s early 80s IHRA tried running off just the bottom bulb, no full tree. It didn't take long to figure how to win, find a car that's time was 1 tenth slower than you, so when his car moved you moved, not even looking at the tree. His reaction was slow because he had to wait to see green (bad reaction time) and you leaving on the last yellow.
That idea lasted about half a summer and hit the sh$t can.
Like one side using instant green and other using full tree.
Sounded like that of way it was worded.
