Well, not necessarily, Bill - if you improve the BSFC by improving the combustion process through various means (direct injection, different combustion chamber geometry, etc) you can theoretically get more HP with less fuel used - NOT that we are likely to see that.  But, I would agree that for all practical purposes, if you want twice the HP, you had better plan on twice the fuel burn.

That's not a bad equation, as a first estimation; but, isn't improving BSFC the point in the reshaped combustion chamber and direct injection?

Just because you have an extra 100Hp doesn't mean you have to use it. 

ok...I agree....that last statement was a little ridiculous.  I mean, we are "hairy chested" and all.
