I once saw a person who had a competion audio setup. The intersting thing about his setup was that he had thermostat controlled nitrous injection for his amps. After the amps got to a certain temperature nitrous was used to cool the amps down. I thought, "what a great idea." Can you think of anything that a nitrous cooling system could be adapted to? Also i heard that shops are going to start marketing nitrogen instead of air to fill tires. They say it is heat resistant. Any thoughts?
