I believe I said some of this before
The three R3350 exhaust turbines produced 150HP each at takeoff power. I
don't know what the ratio was after that. The engine driven supercharger
was single stage two speed. The compound turbines supposedly had enough
exhaust area that they did not produce any back pressure. I assume that
to mean they operated on the exit velocity of the exhaust. H. Karibian

Yes you did.

Don't tell me it was working at sea level. How could that be? :)
Just kidding my friend Doug  Hurant.

A little background on Hurant. Hurant was a flight engineer on
Lockheed Constellations powered by R3350TC engines as I recall.
He should know.
