I made a mistake. The
numbers I sited are for a TSIO 550 with a non-stock 8.5 CR. I do think a
BSFC of .44 or 13.73 hp*hr/gal is a little off. Closer to .42 BSFC I
think. Intercoolers and ambient will have an effect since we are talking
uncorrected for temperature numbers in a plane.

Art, you are correct. The real
BSFC of the TSIO 550 is very close to 0.4 lb / HP*hr or 15 hp*hr/gal

Robert, all the numbers I have seen for a TSIO-550E with
8.5/1 is
14.9hp/gal
FF where did the 13.73hp/gal FF come from?
not
from George I would guess.
