I just read an article about a 100 mpg carburetor
http://www.gofastnews.com/board/tech...lly-exist.html by David Vizard.
What he is saying is that the fuel system is already capable of better than a 100 mpg but the thermal efficiency of the engine is not.
So regardless of what we do with induction systems, fuel injection or carb, o2 sensor, aero mods, hot air intakes or anything else we will still be limited by the thermal efficiency of the machine burning the fuel,
So it’s back to the drawing board to look at the fuel burner not the fuel supplier so may be we need to push engine manufactures as much as oil and gas suppliers.
