I have used pre turbo WI for a long time now, the "pooling" myth is just that.

Some basics of physics are required to explain this.

Pooling is only going to happen when the water droplet sizes is substantial only then will it want to accelerate out of the air stream when going around a radius (easy to work out), this function is directly proportional to the size of the droplet and thus its mass. You also need to realize the air speed is quite slow in the induction plumbing and in the cooler itself, the radius's involved usually are quite large as well, and all of this means that small mass water droplets won't get thrown out of the air stream and onto the walls nearly as badly as people may think.

When you have a finely atomized water droplet you greatly reduce its mass, also to remember these fine atomized droplets have gone through a phase change into steam (in mostly all cases) all the way up to and most of the way into the charge cooler. What you see after the charge cooler is amazingly fine water droplets that are so small they stay in suspension in the air stream (well after the car has been run). You can see this if you have a pressurized water tank. I have never ever found pools of water in a charge cooler nor none of the pipes leading to the engine, have seen plenty pools of oil though far bigger problem than any pre turbo WI system I'd suggest.

Hope this helps?
