Didn't we speculate at one time that a true high energy ignition might not have the SAG issue?  Is anyone running a high energy system, or even installing one to run in the near future?  

 

Rusty (single rotor will run again soon)  

The only racing rotaries not running two MSDs are running two Mallory Highfires. All CD systems. For wet or fouled plugs its a dream come true. It just lights them up. Very short rise times do not allow alternate paths to develop while a Kettering system comes up to top voltage rather slowly. They are quiet enough for pit radios. I don't know about other airplane electronics. The catch is that not all coils will tolerate being operated at 400 volts instead of 12 volts. They are also pricey and not required when running car gas.
