Looks a very nice setup. It appears even the radiator is contained within the engine cowl, it looks like it's fitted on top of the engine.
Perhaps the new metallurgy being used is the quantum step required to make a leap forward in piston engine aircraft design.
Having said that the website is a bit light on specifics, so it's hard to make a really informed assessment.
Certainly looks as if it could be a viable replacement for the TSIO and IO 540 and 520/550 engines.
The only concerns I have are:
1: What size market do they need for it to be a commercial success?
2: Will it fit inside existing cowls using the same mounting points on the firewall?
Do they intend to make an engine for the masses, by that I mean the O 320, IO 360 market.
