So the traditional relationship has been more C.R.=more power.
So, maybe with a supercharger on the "Blanchard Cycle" engine, with a small pressure tank, so the "mini" intake cycle would be consistently pressurized?

This would make the compression load into a more constant and even drag, and it would allow the large offset to still work for the power stroke, and avoid the problem of having the lack of leverage on the up-stroke.

Having the pressure tank getting precharged with some pressure makes it closer to the way steam engines work.
