Bryan, I can't find any reference to BSFC on the Thielert web site. My experience with diesel engines was they are not significantly better than .38 BSFC and they are always heavier than a comparable gas engine for a given power output. Now there have been some significant diesel engine improvements in the last few years. A friend of mine has been working intake ports on a diesel engine and he has flow rates very high with valve lifts near one inch. When you go to direct injection and no pre-chamber, the C/R can go down and these big valve lifts are possible. Add a couple of big turbos and maybe you have something. My intuition is, the main advantage is that it can burn Jet A fuel. If the airliners get their way, gas engines will pay the FAA bill.

Other advantages should be longer = overhaul periods, FADEC already incorporated, elimination of cooling problems, = possibly run on Jet A, Diesel 1 and 2, elimination of magneto ignition and 500 hour overhaul.
