Well for one the compressor really helps to atomize the water which makes it easier to flash and easier to burn in the engine. Also, in my case it HAS to be preturbo because its driven by the turbo. If it was insalled post turbo the pressure would equalize and i would have no water flow at all. There is also evidence that water injected preturbo exdends the compressor map, making the turbo more efficient at higher boost levels.
