I meant to respond to these two claims as well. The glycols have a substantially lower specific heat capacity than does water or 50/50. It is about half that of pure water and about 75% that of 50/50. So, in the same system with the same volume and radiator size, the temperature of the glycol coolant must be higher than with water or 50/50. There is no way around it. The reason is that in order to dissipate the same heat in the radiator, it must increase the delta-T, meaning that the temperature of the coolant must be higher.
I also think the argument that it transfers heat better than water because water can turn to steam is a disappointing strawman. In a properly configured and operating cooling system, the water doesn't turn to steam, and as such, the water is the one that transfers heat better.
I'm not trying to shoot the product down, just trying to inject some reality. The product clearly has some advantages. It is truly a no-pressure coolant. It is also quite a bit less likely to promote corrosion. I don't however, buy the idea that an expansion tank is not necessary. Perhaps a smaller one will do, but all fluids will expand when heated.
It also has some distinct disadvantages. It is far more expensive than it should be, probably because it is a niche product. It has a lower specific heat capacity than traditional coolant. It is also flammable.
They're made by Fortune Auto and are fully customizable/rebuildable and only $1700.00
I'm most concerned for this motor as it has suffered this for part of last season and now again. I helped build this engine so it means a lot to me that I keep it happy and cool. 
My new oil temp, Trans temp and Dif temp gages are Autometer and work well so I'll take the car out to the track in Sept and I'll see what happens.
