Careful Bill, this new found friendship is very fragile. It's true that 
the power comes from burning fuel - pure and simple; More power = more 
fuel EXCEPT when you consider that no engine is 100% efficient, and 
there must be examples out there of engines whose output and efficiency 
are improved at the same time, keeping mileage constant. We're talking 
about a 130hp 2.85 V6 that does 20mpg. Now look at

This is one of the most powerful normally aspirated hp-per-litre engines 
available today. Or if you wsant to compare a similar size engine

(that's 255hp normally aspirated)

Bill, drawing less air in means the engine will meter less fuel.
