It seems to me that you could just use bleed air from the turbocharger by setting a tap in the intake manifold, and then introduce the mist into the inlet of the compressor. Since intake manifold pressure goes negative when you aren't on the turbo then you'd need a one way valve to make sure it doesn't suck water into the intake manifold backwards through the airstone. You'd only get fogging when you're on the turbo this way, but then that's when you really need it anyway. With a little more tubing and valving you could feed the airstone from atmospheric pressure and introduce the mist downstream of the compressor during that period of time (most of the time) you're not on the turbo. If I understand the systems correctly then a setup like this should work on both spark and diesel engines with turbochargers. -- Aviation is more than a hobby. It is more than a job.
