I don't see how comparing a turbocharged, diesel, NA, carb'ed etc... engine in terms of BTC can be a fallacy as long as the fuel is corrected for energy content, they are making the same amount of power, etc... I.e. the one that makes the required amount of power with the least amount of energy is the most efficient.

Yes... again - I'm not saying either way with the specific reference you gave...

I am saying, taking that one example and making it a rule is a fallacy (rule = result however result != rule) of the slippery slope variety (a specific result was a consequence of a step). Which is why I said the statement was "quite easily a fallacy" when this specific discussion started

Another perfect example are turbo diesels which have higher thermal efficiency than their NA counterparts. Thermodynamically, efficiency is calculated in the same manner -- 1 - heatout/heatin because the diesel cycle is simply a heat engine.

Perhaps we're not meeting eye to eye because I'm speaking in the general sense you you're relating to the 95' Mitsu.? Re-reading my posts, I don't think I was very clear that I was speaking "in general" (such as my first post on it ) and I failed (until just now) to realize that you are not
