hmmm. thinking some more... its kinda hard to offset for power BOTH sides of a V engine unless its really asymmetrical. the drawings with the dashed lines for hte piston centerlines in that video showed both sides meeting at a point directly below the crank. to gain the thrust advantage, that virtual meeting point would need to be offset to the 'down' side of the crank...
