Our experience was to use as much N2O as possible as soon as possible in the run. We tried many, many different configurations to get the quickest ET's. Progressive controllers, 1,2,3 stages. Clutch switch, throttle switch, transmission switches. If you have a good enough suspension and tires, hit it it hard at the start. We had a 3000 lb. car, manual transmission. We had our quickest times by far with 400 HP on a single set of port nozzles on a clutch switch and another 200 HP on a 2nd gear transmission switch was about 1 to 1.2 seconds into the run. That worked the best for us with a heavy car. The second stage added about 20 MPH to the trap speed. This was all quarter mile stuff. But we were in 5th gear at about 600 ft. approx. In our experience, the progressive controller was smoother and easier to drive on a lousy track but did not produce the best ET's or MPH.
