My quest is for performance measures of the old & new Lego motors: which one
produces more work output? If one is geared to produce the same RMP / torque
ratio as the other, is the output significantly different?

There is a good page about this here:

http://Prelude.PSY.UMontreal.CA/~cousined/lego/2-Physics/motors/motorPages/motor1.html


Basically, his tests found that the the new 9V geared motor provides at least
twice as much torque at a similar RPM. In practice, some pretty amazing torque
can be obtained with either, and sometimes I favour the old 9V motor because of
its lower height and/or faster RPM output and/or cable placement.

Good luck with the crane!
