No problem with the compressor wheel. Injecting water/meth pre turbo is common practice, especially on draw-thru carburated turbo setups. Obviously the best results would be direct port, and I'm sure over time the water will errode the compressor wheel, but in a draw through setup for example, so will the fuel hitting it. I have never seen that wear out or ruin a compressor wheel on a turbo. Dirt is a much bigger problem. That being said, I'm sure someone somewhere has ruined a turbo from injecting too much or doing it for a long period of time, but it would have to be a hell of alot of miles of use, and we are only talking about injecting this for a few seconds at a time at the most.
