Stupid hp to thrust question

I'm sure NO ONE here, not even the crotchety old fool himself, will deny that BOb
is full of crap (sometimes), *BUT* it was nafod40 whom you (Bob Reed) quoted and
not BOb.

Thank you, Russell.

Does a prop turning at 2300 rpm on a 150hp motor produce more thrust than a

To paraphrase the question...

If I put 150 lbs of crap in a 100 lb bag, and 150 lbs of crap in a 150
lb bag, which bag is holding more crap?

Whoa, Bob.

You have corn-fused me with somebody that gives a CRAP.
Neither my dog or I would care to be involved in this blivet* fiasco.

I'm no authority on the subject, mind you, but it seems you get more thrust
from the more powerful engine because it will turn a prop with more pitch,
thus moves more air, thus more bite. Thus more thrust.

Assuming the same prop on both engines, then no.

A spinning prop produces thrust by throwing air backwards. Based upon
pitch, diameter and airfoil design, a given prop can throw a given
amount of air at a given RPM. It takes a specific amount of power for
the prop to do that.

If the 150hp motor is at full throttle, then the 100hp motor won't be
able to turn the prop at 2300. If the 100hp can turn at 2300, then a
150hp engine will be under-propped with that propeller and will easily
redline (either that or the 150hp engine isn't producing 100hp).

Yes, unless the 150hp motor is an automotive engine, in which case
bolting a prop to it will cause it to violently self destruct before
reaching 2300rpm. 8^P
