Wow, thanks professors, great discussion. I knew I should have paid attention in those high school and college chemistry classes.
We knew the lower thermostat wouldn't change the boiling point, the "hope" was that it would open sooner and allow the motor to run longer before overheating. He told me right off the bat that my radiator was probably not sufficient for open track time, but figured the thermostat was cheap, and it couldn't hurt. No doubt I need the aluminum radiator. That also will take some more weight off the car.
Now, another point of debate, since I don't know much about this? Should I get an aluminum radiator with an "integral"
oil cooler, or get a seperate
oil cooling unit? Keep in mind I won't be open tracking the car more than 4-5 times per year.
