Addendum:
I was just thinking about my post regarding the B-29 engine
swap-out I saw while waiting for my P-51 flight. What
amazed me was the engine burn-in process. They ran that
engine at damn near full throttle for about 20 minutes and
a bunch of us relocated ourselves about 500 feet directly
behind the engine being tested. With just this one engine
running at full throttle, you could lean all the way forward
on the tips of your toes and not fall. The force of the
wind kept you up. Now, that's lift !!!
