Simply put, it states that a chemical reaction increases in rapidity in proportion to the temperature of your mixture.
If you have a lazy burning lean mix that is flaming out around 20:1 AFR, increasing the temperature can allow you to produce the same torque at a somewhat leaner temperature as the flame front will stabilize. Of course, it is not that simple. Increased pressure and turbulence play a part. The Misfit Talon can cruise at 28:1 AFR and above because of added pressure and turbulence.
If you cool your vapor, you chance condensing the fuel back to droplets. Also, even if you keep it in vapor form you may only see the 2-3% TE gain from the elimination of vaporization losses during combustion ( an irreversible loss ).
Also, your 1600 gallons of vaporized gasoline ( at STP - standard temperature and pressure ) will mix with about 9140 gallons of air ( using volume percentages ) to form a stoichiometric mix. This turns out to be . . . 14.7 AFR! Wow, look at that! Yes, if used and detonated in a fuel air bomb, it is quite spectacular. But as far as energy? That fuel air bomb has no more energy than the fuel equivalent I put in my Hemi Magnum fuel tank.
