EFI's claim is this: I will supply sprayed droplets of fuel at the proper air to fuel ratio all the time.
Carburetors claim: I will supply a pre-emulsed froth of fuel and air into the engine at a preset ratio.

Interesting mr. oz.
A 20 degree drop on an 80 deg day would increase the air density about 4%. That would be aroung 16 hp on a 450 hp engine.
If the fuel does go through a phase change from liquid to a gas it would cool the air. The phase change would have to happen in the plenum to be a benefit. It sounded like not just any carb would do this well.
Since gasoline at atmouspheric pressure needs to be up near 500F to phase change to a gass, it does not want to do this. I really do not understand the physics behind emulsed froth. I don't understand why the fine spray of an injector is totally different from this. Maybe someone can enlighten me. I'm always willing to learn.
