Thread: general top fuel ?

Tweet

Original ? by HRDADDY....the driver also has a fuel lever to bring in the second pump. The burnout is done at a much leaner condition but has a tendency to load fuel slightly even then. The engines like to launch under as much fuel possible to set the car on it's tires and through clutch management it carries it out through the RPM band keeping it consistant for the run. Watch the rear pipes during a burnout, their rich and wet. But on the launch, they clean up and start burning evenly (hopefully throughout the run). Single mag is the only thing they run for the burnout for timing control and cylinder pressure control at that "unloaded" condition. The second mag is brought back in by pulling the ground wire off bringing it to life and it is also degreed sighty different for complete combustion therefore the second plug in each cylinder. I'd better stop here because I don't wanna be responsible for readers crashing their head on the keyboard from drifting off...lol.
