You should be able to take methanol down to about -100C. But I think you need
a very large sized refrigeration unit to do so. I had once considered using an
intercooler made of a polymer (which kind I'm not sure...but it'd be a foam)
allowing you to use liquid nitrogen as a coolant. So imagine a liquid-to-air
intercooler without the hassle of a coolant circulation system. Just fill up
the intercooler's tank with liquid nitrogen and leave it there for a month or
two before refilling...  
As for chilling intake air...I was always afraid of the damage that could
result if the intake piping started developing precipitation and water entered
the engine...or would that be a problem?
