I,m following the weber thread and looking at engines in general as I seek to reenter the experimental catagory. The new four cycles are very exciting in weight, power, price and hopefully reliability. I have not seen anything yet about the two cycle direct injection engines.If they are what they claim aren,t they even lighter and simpler at least mechanically? The aircraft I,m looking at uses a 582 but is a superplane with a 912 and 80 hp.If I could get 80-90 hp na at 120lb for even 10 grand it would be a quantum leap. If I could do a complete overhaul with a new cylinder and piston or two and not have red hot exhaust valves and turbochargers testing there limits as I try to relax and enjoy the view,seems....like a wonderful thing. How far from the real world are we from this? Does this new tech have the potential to bring the two cycle roaring back as an aviation powerplant of choice?
