I just installed one in my stocker. It’s a Moroso unit, very nice, finned exchanger, well insulated with AN fittings. My intention is to use dry ice in alcohol. My thoughts are that it will help keep the fuel from vaporizing in the intake, displacing oxygen. My combo is carb restricted to begin with.

Unfortunately, the first test session last month was just after hurricane Ian. Apparently dry ice is a hot commodity during hurricanes. Will have to test with ice and water. Then the first qualifying run, my #7 rod decided to let go just before the traps, so I’m in rebuild mode and testing will resume next year.
