I searched and can’t seem to find it.
It had a video of a prototype engine that some really old guy designed.
The guy died and the prototype was stolen.

Remember anything about it? All I can recall is one about a guy doing combustion flow squish & swirl R&D with a dremel and a bunch of heads, and one about one of the bigger name tuners experimenting with water injection adding a steam cycle to turn a 4 stroke into a 6 stroke.
Can’t find either thread though.
