Hi Sam, There has not been any significant dyne testing of the Mazda rotary in aircraft configuration (and there are no two alike) so I don't think anyone can give you those numbers. Typical fuel burn at cruise is between 6.5 and 8.5 GPH. Everyone uses their own power setting for cruise. Best info we have on BSFC is around .45 - .47 lb/HP/hr.
