Sounds interesting. Would help control stuff blowing past the rings
(less pressure differential), but may rob some peak power since it would
take energy to pressurize the area below the piston. There is one little
problem, however. The conn rod would need a big hole, probably big
enough to make the whole thing unworkable.
