Non Water Based Coolant
Discussion
Has anyone come accross or used anything like this before:

Looks quite interesting.

Yeah i heard of this stuff a while ago now. "Non propylene glycol" dosent boil like normal coolant so you cab run the system open to atmosphere if you want, as it dosent pressurise!
Downside is that youll maybe have to change the rad for a higer flow unit and get a better coolant pump, as it requires a larger flow of coolant to remove the heat, compared to water based coolants.
Apart from that, its a winner i think.

They do a version called NPG+ that is less viscous than the original. They state that is requires no changes to cooling system to use it (unlike the previous version which benefited from modified rad’s and water pumps)
I got a price from the a UK disty - £35+vat for 5 litres (if you buy 3 bottles, which what I reckon it will take to change the coolant in my Griff)
Expensive, but I’ve always been a sucker for something new..

Have to say I'm not too convinced about running this stuff in a road car as when its cold its going to be pretty thick which may cause flow problems in a conventional rad, also the claimed power advantages look like they'll be negated by the increase drag of the water pump even when its up to temp, not to mention that most TVR ignition systems aren't that precise and the abilty of getting the last 2 ° of spark is dubious in any case.
Still if you're dead set on it....

Looks like they are running 100% glycol, possibly a mix of ethylene and propylene glycols, or co-polymers of. Chances are that the mix will be fairly viscous if they are claiming high boiling points. There will be a trade off between viscosity and b.p.
Many nuclear reacters use molten sodium to cool, just like the exhaust valves in my old 16V Golf, should be good for a few million bhp.
There was that Chornobyl thingy though.

Interesting article on this subject on the vintage triumph register (got it via the 427cobra club site, browsing one day 
), it gives some empirical data on water, antifreeze and water wetter in differing ratio's, it makes very interesting reading. See here www.vtr.org/maintain/lubricants-redline.html#coolants just go down to the coolants bit 
, the rest of the articles are quiet interesting as well if you have the time .
