And then we have the most advanced radial of 'em all, the Curtis-Wright R3350- DA/EA series, eighteen fuel injected cylinders and three power recovery turbines pumping out (largest version) 3,400 HP. SFC 'round about 0.36 pounds fuel/HP/Hr.
However, in order for them to churn out all that HP, 115/145 fuel was required.
Worked good....provided you didn't run short of oil...1.5 gal/hr as I recall.
