Default F1 Turbo pumps


Wikipeda sizes each F-1's turbine pump at 41MW. Does that sound correct?

What did the gas-generator for them look like; I assume there were
separate ones for each engine...true?

1 horsepower = 750 watts; yeah, sounds about right.

I'd imagine something like the burner/turbine section of a turbojet;
one turbopump assembly for each F-1 engine. There are a number of
engine designs that use multiple combustion chamber/nozzles per
turbopump. Others have a separate gas generator/turbopump for both
the oxidizer and fuel; the tradeoffs are various.
