It sounds pretty complicated, but it also sounds like that it's based on so many rotating components that maybe it wouldn't be that complicated to rebuild whenever the spark plugs come due. Already, in conventional LS engines you can run spark plugs for 100,000 miles. If it was constructed with an eye toward rebuilding, you could rebuild it and tune it up at the same time every 100,000 miles. Maybe not that much harder than rebuilding an automatic transmission? Maybe that's wishful thinking. 30 PSI will need some stout components. Wonder what it'd sound like. A cross between 3 V6s and a small jet engine?
