waterless coolant
Discussion
Interesting stuff. Main benefit looks to be the higher boiling point since boiling is when impurities will lay down as scale in your rad and block reducing the efficiency of your heat transfer. Also reduced corrosion would have the same effect. Though in my opinion using deionised water should mean very little in the way of impurities and making sure you bleed the system properly and dose it with good coolant removes the corrosion risk. It's a good idea but not too practical.
It's not a magic cure for a radiator that needs re-cored or other things not working.
Running as cool as possible isn't the be all and end all, the engine needs some sort of heat. Not too hot, and not too cold.
The major difference is that the coolant won't build pressure. So reduces the chance of a blown hose and leaks won't evacuate liquid as quick .

Yes it works , Nuff said , it's expensive but if I add up what's its cost to replace all the alloy corroded bits, well let's just say I am happy with it.....I'll wait for captain b

As a chemical engineer in the oil industry dealing with cooling water flows of around 1000 tonnes an hour I know how destructive water can be. Obviously these effects are to a lesser extent in a car that isn't running 24-7 but the same mechanisms are there. I fully believe that this stuff works and would probably consider it if I was sprucing up my cooling system. Even if your coolant isn't reading boiling temperatures you will still get film boiling on the metal surfaces and this is what will lead to scale and cavitation. Couldn't find any tech info on what it's made of but hopefully it's similar density and viscosity to standard coolant for the sake of the water pump. My guess is that it must contain chemicals that will concentrate up in any water (if added) forming a highly concentrated acidic solution leading to rapid corrosion, hence the no water rule.
I promise I'm not a total nerd!! If it works it works! There is a known issue with the life span of radiators on these cars so may be worth it next time you have to replace it.

Lots of comments - technical and...not so technical!
One of the guys that did the Liege-Brescia-Liege rally this year used Evans in his M-series car and was impressed with the way the cooling system handled all the mountain passes. I believe one of the TVR independents are agents for this product.
Food for thought - I'd love to see a long term trial and subsequent (close) examination of the vehicle's cooling system.
