"To summarize:
Engines can run 45-60?C hotter (at the cylinder heads) with Waterless products.
Stabilized coolant temps are increased by 15-25?C.
Specific heat capacity of Waterless products ranges from 0.64 to 0.68,
or about half that of water.
Engine octane requirement is increased by 5-7 numbers reducing engine
horsepower by 4-5%.
Viscosity is 3-4 times higher than what OEM water pumps are rated to
accommodate.
Coolant flow rate through radiator tubes is reduced by 20-25% due to
the higher viscosity.
Race circuits are starting to prohibit waterless products because they
are flammable and cause a slippery surface hazard when leaked."
