I think this was discussed at some point in the past ~30000 posts, but I'll put it out there again:
Would there be any possible benefits to running only 4 cylinders? Would it even be legal?
I m thinking along the lines that a 4 cyl engine is often more efficient than a 6 cyl engine, so maybe a 4 cyl engine with 1.067 L effective capacity might have some merit to it, but this is sooooo far from my zone of comfort!
In particular I am thinking of benefits from having 2 "fake cylinders", which do not need the same space, structural integrity and cooling as the others, or maybe of running only 4 of the 6 cylinders at any time, but cycling so that each cylinder only fires in 2 of each 3 opportunities, with the third one left mostly for cooling/venting purposes.
This might even interact with some rumors of engines purposely revving much higher than 12000 rpm (or trying to).
