Denny,

I, too, can quote and recite basic theory.

However, the only point that I wished to convey was that he was not taking full advantage of the power at hand. The information that you posted will, though, remain beneficial to all future readers.

A prescribed amount of air/fuel mixture is delivered to the combustion chamber due to a series of mechanical events that cause a lesser relative pressure in said chamber. Assume that said amount is completely independent of the ignition system. A "hotter" spark will lead the combustion process to burn more completely (as it takes advantage of more of the ignition coil's potential). Lets call this increased thermodynamic efficiency. Due to this increase and the fact that we have the same amount of fuel/air moving through the system, the system must produce more power (with a properly timed ignition source, and assuming several other constants).
