I'm in the process of designing a small seven cylinder radial air-cooled engine for FAR part 103 ultralight.
It a 148 CID (2.45L) and is mostly aluminum(7075) with gray iron sleeves.
It also has a direct-driven supercharger and a venture carburetor.
Piston compression ratio of 6:1
Max compression ratio of 11:1 (approx(guess(but i think it's good))) Due to the supercharger.
Burning 91-Octane(AKI)
Does anyone know the BSFC of a similar engine or a way that I could guess at the BSFC of this engine without using ANSYS or building and testing.
