So even when you close the gap back down to whats typical on your spark plug, the coil will still produce that same amount of voltage regardless of the gap. So in the end the Honda coil will still be the more efficient ignition coil.
we are working on some testing and in the very early stages of development in coming up with an effective solution to the retard issue, we'll definitely be posting up new info as we gather it. thanks for the input, were always open to suggestions.:thumbsup:
Your first answere is a bit of an over simplification....
There are a lot of variables but the limiting factor to the max output of the spark is the saturation point of the iron in the coil. At a smaller gap depending on a few other factors like resistor plug or boot the spark energy is probably higher. Since there hasn't been much complaints from people about coild failures provided they remove the resistor from the boot I would not be too concerned with the life of the ignition coil or heating the iron up and damaging the insulation.
To sum things up the coils were never designed to work at such high rpms or to be driven with such high density magnets.
Offer stands on the CDI.
I can get something running in a couple of weeks if you build the flywheel to my specs.
For what its worth your ignition solution is already sitting on a shelf for about 40 dollars depending on the qualitiy you can order and move. The only design work you need to do is build a match set of magnets in your flywheel to a set of charge coils. And one finaly tip I will give you is to get awqay from the rare earth magnets in favour of something a little weaker and more mechanicaly robust. I would also go with a much thinner lamination for the iron cores, but you can stay with the old reliable 2 3/4% Si low carbon dynamo special.
Personal feelings nows on Ignitions....
I would REALY like an inductive ignition for the final solution.
Yes they are power hogs but you can make a REALY hot arc with a much longer durration that will simply blow a regualr off the shelf performance CDI out of the water.
Do people realy want this and does it offer a significant enough improvement to warrent the trouble to design?
