Making progress on my Demon
At our long closed local Hudson, NC track was about 4 miles from Don Carlton's garage. We could stand about 5 feet from the cars at the starting line. His tach was a 360* 10,000rpm starting with 0 at the top and 10,000 would be all the way around back to 0. When he was match racing, he would be staged with the tach needle bouncing a little above 0 and as soon as both stage lights came on, the needle would swing almost instantly making the full circle back to 0 (10,000 rpm). The local guys called that "watch Don dial the operator".
I'm 66 and that would have been fine for my drag car. Leave at 8000 rpm and change gears at 8000 (straight up).
