[TR] High-flow thermostat

[Hoyt Duff]

My hotrod buddies turn a regular thermostat into a $30 "performance"
thermostat by drilling a 1/8-inch hole in the flange of the
thermostat. Having seen an actual in-the-package $30 "performance"
thermostat, I can confirm this. I cannot confirm if it makes a damn
bit of difference.
