Not exactly scientific, but an apparent 23 Deg C (73.4 Deg F) drop in Charge Air Temp is awesome.
In general this should be a good thing, but one must also consider the dew point of the air or you can and will get a rain maker into your intake.
You can find this out on dew point tables if you know Temp, RH and pressure.
Sounds very interesting.
