I read the link you posted on the ignition power amplifier.

I could be wrong the energy (area under the curve) appears to be only slightly more than the conventional. But if you calculate the power based on the peak current, it does appear to have several times more peak power. Not an expert on spark plugs.

That said, a cdi ignition system has far shorter duration but very high ionisation voltage. Someone please chime who knows more.
