I was looking through an automotive performance catalog and started thinking about fuel coolers (typically a container with a coil inside that you fill with ice or dry ice or something) to try to reduce the temperature of incoming fuel. So the end result is a cooler fuel, which will increase the mass flow rate through your jets or fuel injectors. You have not increased the energy of the fuel at all, actually decreased the energy content of the fuel due to lower entropy. It seems like you would want to do the opposite, increase the energy of the fuel (add heat) and simply compensate the lower mass flow rate with larger jets or increased duration of the fuel injection pulse. Anyway it just seems like an inconsistent and difficult way to add more fuel. I would appreciate any good input from a scientific point of view.

I think the answers so far have not reinforced what I already stated. Cooler fuel is denser fuel is more fuel is more power. Great, I understand that. But if you need more fuel, why don't you just re-jet your carb? Maybe the guy who said it also cools the intake air was on to something, since its a lot harder to add air than it is to add fuel. I'm looking for an answer about the energy of the fuel, not the quantity.
