Pardon my ignorance: why is the 7M-GE so much less efficient?

Play nice.


Even if you were comparing one Toyota to another there are a lot of things not being taken into account here. Compression, volumetric efficiency, internal resistance and friction, interia and the weight of the stock internals, the RPM at which the power is made, the tradeoff between torque and HP, bore, stroke, valve timing, factory tuning, and so on.
