I wanna make sure i understand this correctly.
Intercooling is reduction of temps in cold pipe and intake mani correct? And methanol is more effective for this.
Charge cooling is reduction of temps in the cylinder, and water is more effective for this.
So if one is spraying to reduce knock, water is the best option as it cools the cylinder most effectively (with some meth added to help dispersion & some intercooling). Once knock is eliminated, timing advance and higher boost levels can be had.
I just don't see the benefit of spraying mostly methanol, other than that let's you lean the mixture out a bit. I don't understand how much power is able to be had in a setup like this (though i've seen graphs showing higher mixes of methanol resulting in much more power than water alone).
(john, i just posted a similar question in the gasoline forced induction section, and it should have been here. Feel free to delete the redundancy!)
