Thanks to everyone for your input in this informative and idea inspiring thread!
I am wondering how colder ambient air temps would affect the evaporation of pre-compressor water/ETOH droplets. Hotrod and I live in Colorado and can experience cold winters. Larry, have you had any experience with your pre-comp injection in the winter time? I just wonder if the water mixture would have more of a chance of not evaporating fully and possibly damaging compressor blades.
Another thought relating to the idea of increased air mass and O2 content with pre-comp WI. Some posts here have suggested that the increased air mass due to colder/denser air would not have more O2 content because more air is not actually entering the system through the intake. Wouldn't the O2 content of the air be increased with the addition of WI prior to the turbo because H2O and methanol themselves contain O2? I thought this was one reason for using methanol injected after the turbo because it has a high O2 content (in addition to it's knock suppression qualities). What happens at the molecular level to the O2 in the water and/or methanol at the time of evaporation?
