I think it's thrown out money, if you really intend to run an engine in these temperatures the "cooling" is significantly reduced (if there is any at all ?) and will stress all other components as well. I would invest the money in better radiator ;-)pmessling said:
My python is squeaking, do you think this stuff would help? 
The only benefit I can see is that you'll get less pressure build up in the cooling system at higher temperatures.
I don't think it can improve cooling efficiency as that is governed by the heat exchange capability of the radiator - and that doesn't change unless you increase the surface area or radiator material.
Personally I would rather have steam generated that blows the top off the header tank and tells you the truth of what's going on than an overly hot engine that's potentially destroying itself!
And, after all, who really believes their temperature gauge .... steam billowing out means "stop! things are too hot" but a gauge showing a high value "that's just because it's a TVR sir"

From my basic recollection of school physics, isn't the specific heat of a liquid indicative of it's cooling ability (or heat capacity)? And therefore if it boils at a higher temperature it is also likely to have a higher specific heat so would be more effective at heat transfer to the radiator....
As per Wikipedia...."[specific heat capacity]....which is the heat capacity per unit mass of a material"
Why should it therefore be concern that it still cools at high temperatures?
It's actually a benefit that it doesn't boil as that significantly reduces the heat transfer capacity of any liquid, so it would still keep cooling.
The engine temperature will read as relevant, and the fans will still kick in as per usual at the same temperature, but the higher specific heat would in theory keep the coolant temperature lower for longer based upon the same amount of heat energy output from the engine, and the fans would kick in less often.

Hi,
This company is a client our's here at www.ppc-rescue.co.uk and I've worked with them on their cooling fluids marketing. It's a division of www.hydratech.co.uk. They are market leaders in a specialist cooling products from simple carvan antifreeze, ground source heat pumps, solar panel cooling to ice ring coolant.
They tend to specialise in the latest eco friendly non toxic coolants.
If anyone is interested, I'll put you in touch with them. I've always found them to be very technically focussed, capable and honest.
Cheers
John

You know how the needle on the temp gauge suddenly flicks up & you get that sinking feeling( usally in traffic) well mine flicked down !!...=Big Ally Rad 
Mind you have had the same sinking feeling when mine flicked down in the past, the missus was not best pleased at all
