Manifold heat cross over physics and benifits

Rusty, I reckon that's why MPFI manifolds / systems are the best of both worlds. Amongst a multitude of other benefits, they allow a cool(ish) denser charge with out the vaporization and fuel distribution issues of a wet manifold.

Not really. MPFI manifolds don't have to carry the fuel from the throttle plates into the cylinder. You don't have to keep it suspended in the air mixture through the port. You just spray the fuel past the valve into the cylinder. Since the fuel is not being carried through the ports, it doesn't have the opportunity to condense in the ports because you are only moving dry air.

With a cold engine and cold port passages, sometimes the fuel will condense on the port walls because they cool the mixture to where the fuel condenses on the port walls for a carbureted engine. Since the FI engine is not carrying any fuel, it is not there to condense on the port walls.

At the same temperature, the density of the intake air is the same for both carbureted and fuel injected engines.
