A friend of mine last week sent me a fax on, I think, something similar
to that above.  In the march issue of one of the high-performance
NASCAR magazines (I do not remember which one, but I can find out)
was an article written by David Vizard on how they simply hooked
a capacitor to the secondary circuit (actually a commercial product)
and did a bunch of dyno runs.  The fax was very hard to read, but I can
get more info from the person who sent it to me.
