Hence 3 cylinders and even 2 cylinders in the new fiat "twinair" engine.
Only a boxer engine's arangment of cylinders can be truly balenced in the 1st and 2nd order, hence porches love of this arangment.
P.S. This should be an interesting thread
so that would explain why larger engines have tended to produce less power per cc as opposed to the smaller units then?
but it's also easier to get mroe power out of them with a bit of fiddling yes?
can't remember which mag its in, but a recent 5 litre V8 was supposed to only put out 126 brake in one version of a car it's fitted too with another version putting out 260 and above, obviously yank
