  All,

  If I did the math correctly the sfc is a maximum of about .5
  lb/hp/hr at max
  power - which is better than a small turbine of this power.  All it
  needs
  now is a turbo compound to get the efficiency up to around .38 or so...

  Thanks for doing the BSFC Math Norm. That was on my list of things
  to do.

 How does this engine differ from the Aixro aircraft engine? Bearings
 maybe?
 John McEverett

 IMHO the core engine is the same.

Attachments don't always stay attached on rather old threads :)

I went back and dug it up for you.
