I guess I should clarify for woody, I agree 100% that for a consistent solution the Supercooler is the way to go. I would FOR SURE buy a supercooler before the full CryO2 system. I'm thinking this for more of in-between run cooling. Rather than wanting to give my car an hour to cool I could simply give it a spray with some CO2 and run again. If I can put the system together for under $100 it would be worth it in my opinion.
