.... a 60° V6 I would argue. And its still a more balanced configuration for a V6 than 90°.
doesn't 6 equal-interval firings give a longer,heavier, thicker-cranked engine with more bearing loads, area, and friction ?
at current or any feasible bore:stroke ratio and cylinder spacing
(though maybe not at the frozen NA V8 dimensions)
As far as I understand, the best balanced V6 configuration is a 60° V6 with 6 throws 60° apart. But that would be longer, and have 7 main bearing as opposed to 4, so that would be increased friction, and a longer engine yes.
But there is also the option of keeping the 90° but just allow offset crank splits by 30°, and this would make an even firing engine which has better harmonics than an odd fire, and still only 4 main bearings. The reason I would argue for an even firing engine (besides sound) is that these engines have to last for many miles, and im pretty sure that excess vibrations is very bad for reliability, both on the engine side, and the electronics strapped to the engine.
