Lycoming T53 turboshaft
860 hp.
688 lbs dry weight.
What's so special about the HH-43 turboshaft engine?
The proposed Fi-339 helicopter was powered by a BMW-132 engine.
947 hp (BMW 132J).
1,157 lbs dry weight.
Heavier then an early model turboshaft but I suspect fuel economy was better. So there might not be much difference in useful payload (after subtracting fuel weight).
The Piasecki H-21 was powered by one. Piasecki H-21 - Wikipedia, the free encyclopediaCould someone make capability estimates for a helicopter powered with, say, R-1820?

There were no turboshaft engines during WWII.

Very true but people who look at the capabilities of modern (or even 1960-70) helicopters and wonder about their usefulness in WW II should be aware that there was a tremendous difference in the capability of a 1960s helicopter and a WW II helicopter.
What's wrong with that?

... artillery spotting. A mission just as important as air superiority and arguably more important then long range bombing. But apparently this crucial mission isn't glamorous enough to earn any respect.
