Definitely the more the better, but today's injector designs combined with high swirl chambers and higher compressions (and higher temps associated with it) have atomization handled pretty completely. Volvo is coming in with numbers like 4% of the gasoline that isn't completely evaporated prior to combustion. During combustion I'm sure almost all of that evaporates and gets combusted given the incredibly low HC emission numbers from many ULEV engines today. I'm pretty sure that my 454 with its functioning exhaust crossover, 195-degree stat, under-hood air ingestion, and water passages right in the intake does an even better job than that when its really hot
It cooks high-temp paint off the intake so my guess is that droplets of gasoline have no chance
