Wrong again, suggest you go read the first paragraph of the Stewart article, which is what most people who have been around high performance street cars already know: A thermostat is essential in preventing overheating. What Stewart is saying is that WHEN THE THERMOSTAT NEEDS TO BE OPEN.....a faster flowing passage is what you want (vis-a-vis their hi-flow thermostats.) They are then saying that such faster flow is not a bad thing. You are taking that out of context to suggest that it supports your theory that if a hi-flow thermostat is good, then no thermostat at all is better.
Look, it doesn't take a rocket scientist to understand that the two purposes of a thermostat are: 1. Achieve and maintain under all conditions the "optimal" operating temperature for a given engine (to Madmaxx's post above) and, 2. Regulate/control the flow of water/coolant in order to accommodate conditions (like stop and go driving on the street), where airflow across the radiator and water flow from higher RPMS aren't available to assist in creating the needed heat exchange and dissipation. The absence of a proper heat exchange is going to increase the chances of a healthy car overheating, and guarantee an unhealthy car to overheat. Sorry you can't get your head around this.
I tend to agree with the notion the OD pulley is possibly a contributor given you have ruled out the thermostat. Rhunt...is your engine carbureted....are you sure about your mixture tuning? If its running too lean, even by a little, that will drive temps up and nothing will stop it.
