215°F is not excessively hot. Have you tried to keep running it to see where the temperature levels off?
You can run a lot hotter than that in a pressurized cooling system, even with water. For every pound of pressure exerted on the coolant in the system, the static boiling point of the coolant is raised by approximately 3° F. 13 PSI would have a boiling point of 251°F (212°F + (13 x 3)), while a 16 PSI system would have a boiling point of 260°F.

Ethylene glycol, of course, will raise the boiling point. Evans Waterless coolant will raise it even higher.
Questions:
- What thermostat are you running? Temp rating? High flow or standard?
- Is your water pump under-driven? Does it cool down at lower RPM? To what temp?
- Is your radiator sealed to prevent airflow from bypassing it?
