Preturbo water injection.

Problem here is that the main cooling effect is from evaporation and water takes a certain amount of time to evaporate no matter what the temperature. Question is whether or not that placement will allow for enough time. That being said, most people who put the WI right before the TB probably aren't getting full evaporation either.

Hey Rich I know what yall are saying. But I always thought that keeping the fogger as far away from the TB as possible was good but for other reasons. Spraying water into air it doesn't just evaporate. Well it does, but not much. My reasoning for keeping it further from the TB was for more even distribution. If this was a Wal Greens commercial and we were in 'Perfect', we would be spraying the water in a very fine mist directly into the cylinder right before the spark begins combustion, no? That way the water pulls heat out of the charge and nothing else. We don't want to cool the intake manifold, seats, valves, combustion chambers, cylinders, and pistons. We just want to keep the charge cool enough to suppress detonation. Of course on second though if the water did cool the cylinders, the the cylinders cool the charge too. So I dunno, your the WI guy not me. Straighten me out!

Droplets can indeed damage compressor wheels, so you have to make sure that all liquid has vaporized before it reaches the wheel.
The Champ Cars ran a methanol nozzle upstream of the compressor wheel. The inducers of their compressor wheels eroded. We ended up nickel-plating the compressor wheels to resolve the foreign object damage.
