Last think I read was to downgrade the power for multiple engines. Rate each engine at 75% their normal, but it was written for a twin. Have a fellow now working on a 110" B-17 based on old plans, and we are trying to figure an appropriate power set-up for the A/C. We want to move around things within each nacelle to fit wahtever power is decided upon.

I would think maybe it to be even lesser on four engine. Maybe rate each at 65%. I cannot find such infomation in my design books, as they mostly pertain to single engine jobs.
