power vs fuel consumption at wot Lets say an engine is 100% efficient how much is needed of gasoline(only) to produce 100 ? 200 hp? If anyone has a graph or something that would be great I just really would like to know. Something like that should be posted up top.

Having said that, you can get an "estimate" of fuel requirement by using the BSFC values that are found w/ various combos. [Brake Specific Fuel Consumption is the fuel, in pounds per FWHP, per hour, the engine consumes.]
IE:
NASCAR engines can see BSFC'S at .3+
Our "everyday" engine can be in the .5+ range.
And, the forced induction engines are in the .6+ area.
The math is simply:FWHP x BSFC = fuel consumption
BTW, Max fuel consumption occurs at max torque..
