How much power is a B-29 generating during a full throttle run-up before

That goes back to the basic definition of HP. You have to do work on an
object, since HP is the amont of time required to lift an {whatever weight}
object to {whatever} height.

The noise and heat being produced, and the fuel being burned suggests
something else, though. :-o g
