Malcolm, All,
Thanks, I see exactly what you're saying now... Have you compared
the quenching ability of twin coil with that of a regular coil? I suspect
(based on Robert Steven's results) that a twin coil may give a more
optimal loading. Maybe even a triple or quadruple coil would be better
as far as optimal loading, but probably not for spark length.
Comments?
