Care to share your reasoning?
My understanding is that for max effect, 2 nozzle setup is better than one nozzle.
From elsewhere:
Mounting a nozzle just after the intercooler provides maximum distance traveled from the spray point to the combustion chamber. This ensures that the mist is carried by the air for a longer time period. More time allows for more complete evaporation. More evaporation guarantees more cooling.
A throttle body-mounted nozzle works exactly the same way but in reverse. Less distance traveled = less evaporation = more droplets ready to turn to steam INSIDE the combustion chambers. This reduction in combustion temperature boosts the air/fuel charge's octane rating in a huge and very beneficial way. Of course, one may run a single medium-sized nozzle midway between the two ends. This delivers a compromised mix of both cooling and octane vs. maximum amounts of both.
