Another suggestion is to use alcohol and dry ice. Cool the alcohol in a dry
ice bath and then spray the alcohol on the intercooler. Flammability
considerations might make this undesireable but alternately the alcohol
could be injected directly into the intercooler intake to cool the incoming
charge well below ambient. Dry ice is easy to handle and store-- a foam
cooler is all that is required. The simplist approach might be to use the
alcohol as fuel to run the engine, too, and dispense with gasoline
altogether. Otherwise, it probably would need a method of adjusting the
gasoline/air mixture to the lean side to compensate for the alcohol added to
the incoming charge. I haven't tried it, though....has anyone else heard of
someone trying this?

Rick,
I am in agreement with Mayf, and to further his comments, you can further
reduce intake temps below ambient, with water spray on an air/air charge
cooler, and then using an air/ice water system. I utilized this compound
charge cooling in the turbo Merkur and found inlet temperatures of less than
80 degrees f on a 100 deg day with lots of flow and boost. (75PPH of air at
96" Hg absolute). The cooling systems get a little complex, but not nearly
like one using some type of cryogenics. I have no data with the cooler on
the N/A motor, but others that run a like system say temps in the 40's are
typical.
