But the R-1340-43 wasn't more powerful than the S3H1 it was limited to the same 550 hp continuous and it did not even put out as much power as the S3H1 for takeoff since this was also limited to 550 hp while the S3H1 put out 600 hp for takeoff.
OK. Thanks for the correction.
So Sheila thought she had found a more powerful engine that Wemple might have installed in NR16020 ...
What's the definition of power--speed or fuel efficiency?
Johnson was looking at the turbo aspect (thanks again to Gary for the after-engine turbo info) for a reason; in XC-35's case, it seems to be speed (power?) at altitude; however, his parallel goal was endurance. If he chose 1340-43s in the end (which he did), it's reasonable to ask whether the after-engine turbo aspect contributed to overall endurance.
