The efficiency of IC drops, seems a bad thing....
But wait, on the other viewpoint, it means IC could be eliminated. (maybe a good thing, eliminating pressure drop & long routing)
Moreover, post-IC temp can not explain the efficiency shift of the compressor itself.
Averagely, pre-IC (i.e. compressor outlet) temp actually drops as the jets get bigger. So we might roughly say the compressor efficiency benefits somewhat by more water (within the range of this experiment).
(However, do we really need the final temp below ambience is another story)
As Larry (Hotrod) mentioned in another thread, 2~3% injection rate may be ideal for the pre-compressor injection. Maybe someone can help on this in this experiment.
In addition, I'd really like to see MAF info along with the pre-compressor injection, if possible.
