60 FOOT TIMES

My Dart loves the slow power application of a CO2 throttle controller. With a 4,000 rpm setting (about 1/8 throttle opening) it takes .05 for the throttle to hit 100% opening on launch, 2.45 low, 33 10.5 or 33 15 15 tires very little difference,549 cubes, 2905 lbs race weight. 60 fts of 1.224 and 1.226 on first outing, poorer air second outing slowed to 1.244, 1.246 on saturday with 3000 da,, 1.250 as the day heated up to 3600 da. Car went 8.60s at 157 mph to 8.700 at 154. In my situation with 50/50 front rear weight, it loves the soft hit for the first four to six inches of car travel. Reaction times made me go to 1.04 in the box versus 1.08 to 1.10, but for bracket racing, no problem. When i was trying 5,000 launch, the car was too violent and hit the bars so hard it would spin. I could feel it. And couldn't do better than a 1.25 to 1.29. So ya, every car is different, but I am sold on that initial ,but very short, "soft hit"
