I just went through this with a few other people on the newsgroup and ended
up writing a MathCad program that calculates the energy available from a
conventional system as a function of the coil parameters (resistance and
inductance), system voltage, and RPM. In the end the question was settled
by someone who had bothered to look up in their Bosch Electrical Systems
Handbook to find how much energy was actually NEEDED to accomplish the
ignition task. The end result was that the conventional system provides a
MINIMUM of TEN TIMES MORE energy than is needed at ANY RPM under 6000.
I love CD ignitions. And I don't really aspire to be classed as a
retrogrouch in this issue, but the advantages of electronic ignitions really
lie in reduced maintenance and long term stability.
