after re-reading this thread and Lynn E. Hanover remarks, it makes me wonder if my twol crane hi6 with two lx92 coils was the right way to go.
Damn it Lynn why did u have to make this post?

Check the energy output of your system against the energy output of the various MSDs. If total output (in millijoules) is in the area of the MSD, that would be good enough, and little improvement would be realized by changing brands. If that data is not available, check input current at similar RPMs, and that will give you an idea of output.
The multi spark feature only works to about 3,000 RPM. Above that its the same as any capaciter discharge system. GM has a P/N for several. NASCAR has a spec version that must be run, and has a spec cannon plug. GT-1 and TransAm cars run them. maybe there is something there after all.

Crane Hi-6 amp requires 7.0 amps max. at 10,000 RPM and Primary Energy output 1200 millijoules/sequence. The Peak Spark Gap Current is 510 milliamps with LX92 coil.
MSD 6A requires 10 amps at 10,000 rpms. Primary Energy output (max) = 105 to 115 mJ per spark. I don't know what the max spark gap current is for the MSD blaster coils. Doesn't say on their site.
Too bad I don't have a clue what any of those numbers represent except for the fact the the crane unit draws more current from my electrical system.

A Joule is the same amount of energy as one watt second. So 1,200 milijoules is
1.2 watt seconds.
What a shame it is that all manufacturers cannot just publish two columns of data side by side in plain english.

the manufactuerer can, but the marketing dept wont.
i looked at the rx8 harness, the coils get common battery power (or dont in this cars case)
