Specific Fuel Consumption (sfc) of the R-4360 engine?

[Stephan Wilkinson]

What was the sfc of the Pratt & Whitney R-4360 Wasp Major, and how did it compare to the sfcs of other large airliner engines of the 1950s? Anybody know?

Oh, so I guess we're not talking race power here. That's where it gets interesting...

If this helps, from Paul H. Wilkinson's Aircraft Engines of the World 1959/60:

page 251, Pratt & Whitney Wasp Major R4360 CB2 (commercial)
Fuel consumption (cr.) 0.43 lb/hp/hr

page 255, Wright Turbo Compound TC18 EA4
Fuel consumption (cr.) 0.38 lb/hp/hr

If you don't have access to the book for further specs, send me a PM and I'll try and help with more info from those pages. Someone else may have more first-hand info on commercial use. All the best.

in generic simple-man terms, I always thought this was 150-200 gals per hour for the 4360, depending on lean settings... and the C-97 would flight plan for 600-800 gal per hour of fuel burn.
