Well, I'm sure you know this at some level, but if you're at the best power air/fuel ratio and you add more fuel, all the spark in the world won't make more power.

Big power increases from new, "better" systems actually come from fixing a problem you didn't know you had.

If you truly want to take a giant step forward in ignition, you need to investigate Electromotive and like firms. Crank triggers and computing technology combined with individual coils on the plugs or something approaching that allow the coil to be much more saturated and deliver a much bigger spark if it is needed to jump the gap. Being able to set your ignition lead electronically helps a lot, too. High dollar racers like to tailor the advance for each cylinder but this requires a lot of dyno time for a few hp gain, IMHO.
