Imagine if you tried to get 100 hp/cyl out of a 2cc model airplane engine or something.

Even hp/liter is more usefull when talking about how physically-stressed an engine is, for that reason.
Point taken, I guess the next thing would be to determine surface area and how much stress is distributed per square inch of the H6 vs the H4? The H6 runs less timing obviously than the 4 cylinder.

I'll leave the calculations up to you cause you are the smart one. Or maybe I missed your point?
