Injecting prior to turbo comp' impellers

[masterp2]

Those are good concerns Joe.

If injection pre-turbo is implimented with moderation, I don't think you will have any problem. Freezeup more of a concern for many. I have been thinking along the lines of a temperature switch post-IC that would inhibit pre-turbo spray if not hot enough.

You really should play around with atomization, though. You need a very fine mist, more like fog. The biggest danger is impingement on the blades from larger particles. Maybe try fog nozzles under the highest pressure you can get, at least 100 psi. Multiple nozzle array vs single large one.

I am going to be trying some of this as our weather warms up.
