OK, here's the cat's whiskers ... Dana's custom Intercooler recipe.
Take some dry-ice (about 5 lbs.) and chop it up with a hammer so the pieces
are about the size of beach pebbles or small rocks. Dump them into an
insulated container (a dewar or cryogenic container is best). Add a gallon
or so of rubbing alcohol (Isopropyl Alcohol) and stir gently.
Now run your intake charge line through the liquid mess (called a slurry).
Make sure your line is metal. Seal it all up (leave a vent for the
evaporating CO2), and you'll transfer more heat than you can ever dream of
making.
I haven't tried it yet, but I'm playing with it for 2003.
Water makes dry-ice clump. Methanol is too volatile and flammable. Isopropyl
is cheap!
Only thing colder is liquid Nitrogen ... and that would look WAY COOL as
you're pouring it in at Bonney with white clouds pouring out on the ground
around your feet.
