How Gearing Effects HP from 1-3rd in 727's

The problem is there's only a few ways to make power especially huge gains.

Paraistic loss and friction which is not what we're talking about. VE which is how we normally makes gain with huge amounts of power(more air per stroke). And what your seem to be talking about is efficiency which gains are to be had but no one has found gains like that. Not to say you can't come up with something no one else has but it seems unlikely especially with the research from the automotive industry to big race teams looking for efficiency and power. And to make the gains your talking about most of the fuel must not be burnt in an average engine.
