The spark was impressive! A bright blue high density. 50,000 sparks per second

I could not comprehend what I was seeing.

That is 3 million RPM in a rotary. No wonder the 2nd gen RX7 coil failed.

Yes ....3 million RPM sparking once per revolution.

10 sparks per revolution 300,000 RPM.

100 sparks per revolution 30,000   RPM.

I am building three new systems to do some more testing.

Now all we need to do is figure out how to get the coil to live.

We may have to back off on the battery voltage.

Better pictures shortly.

What did you use as a trigger for that frequency? Kevin Alderman

A pulse generator.

In actual operation it will be limited by the number of teeth on the trigger wheel.
A 6" dia. #35 chain sprocket (3/8 pitch) would be limited to 30 pulses per revolution
for a 2 rotor. About one pulse  every 6 degrees of e-shaft angle. Well under the
maximum capability of this ignition system.  One ignition system per rotor
if you use a waste spark coil. You could also use 4 ignition systems and 4 coils.
One  per plug. Highly redundant.

It would still work and  be the same at 11,000 RPM.
