Improvements to the Rotary?

The video mentions the inventor tested it out and it resluted in lower EGT's, but doesn't say much else - what about results for HP/torque, emissions, fuel economy, etc? The only potential downside I see off the bat on this design mod is ignition reliability. You'll need a very healthy and consistent spark to be able to ignite the fuel/air charge thru that narrow slit. Brand new ignition system designed for this should have no problem with it, but as it degrades over time it could.

I agree. Given all the improvements in automotive engineering in general, this should be a walk in the park for modern ignition tech. Even an MSD system should ignite the mixture through that slit without batting an eye.

I've been looking for a way to get in touch with Ernie for more info.
