Ed: If you pulse the primary with a shunt selectable capacitor and gauge the
output voltage an ideal capacitance value can be found. Most auto coils fall
in at about 2.15 uF. This value is not applicable to other coils or home
made coils as the secondary resonant frequency is not similar. Just as you
select the correct tap resonant primary point of a TC you can select the
size of the correct primary capacitor for a make-breake coil system.
