I just found the reference to the lowest recorded SFC in an aviation
engine.  The 1950 Napier Nomad with a 0.36 SFC turbo-compound,
supercharged 12 cylider diesel 3,000 hp.

worthy challenge to beat with a 16X rotary engine. (not the hp, the SFC)

They have one in the Ottawa museum as well as the Smithsonian.
Here are some pictures I took at the Smithsonian.
