My initial reaction was one of skepticism, but this stuff seems pretty interesting.

Evans NPG Coolant and related components are designed with the ability to reduce hot spots while raising the coolant boiling point and decreasing the volume of vapor generated when compared to typical ethylene glycol / water (EGW) mixtures. Race car testing has shown that even if forced to operate at up to 300° F, detonation control and previously forbidden combustion pressures and temperatures are no longer the danger they were to thermal engine efficiency and durability.Within all cooling systems is the normal occurring phenomenon called Nucleate Boiling:
Nucleate boiling is the boiling that takes place when liquid coolant comes in direct contact with the hot metal of the engine block or cylinder heads which has reached or exceeded the boiling point of the coolant.

Is Evans advocating operating engines at substantially higher temperatures?
Not really. Operating temperatures are normally only slightly warmer than those of water-based coolant. When the engine is stressed and temperatures rise, the cooling system can accommodate that increase in temperature without cooling system failures.
How does Evans Waterless Heavy Duty Coolant save fuel?
In spark ignition engines Evans Waterless Heavy Duty Coolant saves fuel by better control of metal temperatures and the avoidance of hot spots. The consequent reduction of knock permits more efficient spark settings on engines having electronic controls with knock sensing inputs. In heavy duty engines having on-off fan clutches, the “on” temperature can be increased to 230° F, keeping the fan off a large percentage of the time and reducing a significant source of parasitic drag.
Evans Waterless Heavy Duty Coolant contains a blend of glycols, including ethylene glycol, which is toxic. How toxic is Evans Waterless Heavy Duty Coolant?
Evans Waterless Heavy Duty Coolant contains a substance that inhibits the metabolism of ethylene glycol, preventing its toxic metabolites from forming. In tests on rats according to EPA regulations, no rats died eating Evans Waterless Heavy Duty Coolant, even in quantities that completely filled the stomachs of the rats, indicating a very low oral toxicity.

Judging from what I have read all you may need to "convert" the SVX is a smaller pulley for the water pump. Then again, I'm still not an expert.
