The biggest radial engine topped out about 5000 cubic inches
and 4,000 horsepower in the late 1940. They were also about
3,000 to 5,000 pounds in weight with a prop installed.

Turbine engines are much lighter in weight and have 15,000
to 75,000 eshp in thrust, jumbo airliners and freighter are
only possible with the jet.
