The swirl combustion thing, you can find hint of on Larry's site. (TheOldOne.com)

Basically, the same method you're thinking, but with more work applied to actual flow dynamics and combustion shape manipulation. I believe the articles you'd be looking for are "Talking heads" and "Swirl Power". They're Mag articles from years ago (more like decades) that Larry was working with Hot Rod and Circle Track magazines as reporting bodies.

They're interesting reads, at least.
