another 2 minor points:
1. a 2 litre engine at 1 bar boost and 5Krpm will be consuming around
10.000 litres of air per minute, or 10cubic metres of air, which is about 12.2 kg air/minute.
10% of that equates to 1.2kg water /min, that's quite a lot isn't it? With the aquamist pump and nozzles, it will have to be closer to 3% in practice.
Would this be enough?

2. Wouldn't the extreme centrifugal forces in the compressor force the tiny water droplets to become liquid again?
A 2 liter engine consumes 2 liters every TWO revolutions (720 degrees) so assuming 100%VE, 100% intercooling, it would consume 5,000 liters/minute.
