water jet/s location

[Hemi T04]

In thoery what is the best location for the water, or water alchohl jet.
Either into the turbo inlet,Before the trottle body or directly at the port of each runner like a fuel injector- i can see advntages of the furthest sytem- in that the water having a cooling effect on the whole induction system- but also a problem of maybe not vapourisng properly and sticking to the walls casuing distibution problems.( i some cyilders will get more water than the others- and will hence ping first).
Compared to directly into each head port from the runner, where all the water will vapoursie in the cylinder.
I know you could use more water effectively the further you go back towards the airfilter- as it has more places to vapourise.
Note - i just talked to a guy with an 850 hp methanol injected( no water or intercooler) drag car and he mentioned he gained sixty horsepower by moving the methanol jets right next to the port- compared to the plenum runner intersection.
what do people think?
