I can't imagine that having water injected before the turbo would be good for the hot compressor blades...
I was asking about this because I'm planning on a "X" nozzle set-up in two stages (where "X" is yet to be determined). When a high boost condition exists where I'm boosting beyond the efficiency island of the turbo, I was wondering about cooling the intake charge before the IC so that the IC would not heat soak. I'm looking at total efficiency of the system vs. local efficiency of one component.
I have a lot of freedom to place nozzles both in and out of the intake. So, currently, the set-up looks like this: At 15psi boost, a 3 GPH nozzle right before the throttle plate and two 1GPH nozzles come on to spray on the IC. At 20psi, a 5GPH nozzle before the throttle plate and a 5GPH nozzle comes on between the turbo and IC.
