Hi Guys:
            My good old friend Don Smith, (remember him guys?? Tall
fellow, white hair, rides a "Pink" V-Max, has short temper and likes hot
food??) Well Don came up with the idea of using "Hotter Coils" for his
V-Max, He has ordered a set of Dyna DC3-1 single post 3ohm pri,14,000
ohm sec. According to him these coils have 30,000 plus output.
            He told me to share this info with TheList, (see, he's not
"that bad")

----------------------


Seems like I heard somewhere that using high output coils will burn out 
the ignition box. Mind you this is just hearsay, but I ain't about to 
experiment on mine. Also you will have to use well-made silicone wires 
to keep all that voltage in.

I was talking in length about this with Don. He has to machine some custom
brackets to mount them - not a problem for someone who works in a machine
shop day in day out.
Stock coils run about 2.3 Ohms. This limits the maximum amount of current
running through the coils, which means they won't blow the switchers in our
precious black box, the TCI unit (thanks for the concern, Mike). Big
question is coil inductance, which there was no spec around. This will
impact high rev performance, when actually the power (and spark energy) has
to build up quickly. Then, we don't know how well primary and secondary
windings couple, which raises the question of further energy losses (touch
a transformer and you'll know there are some!) Obviously, 30kV are enough
to ignite some air/fuel mixture, but there is no spec about what frequency
this coil is going to put out 30kV and what the input voltage source is
(12V? 14V? 16V?). Specs are only as good as the conditions they are tested
at are defined.

I'd suspect they will work, at least up to 6krpm, then I am very curious to
hear about their performance when the needle climbs to 10,000 (under WFO
conditions, of course).
