so this is about the most amazing coolant i saw last night at the kinod. its called the moonshine EVANS nrg racing coolant. from what basics i've learned in auto class, this was never brought into the picture, so lets figure out the pros and cons of this thing. give ur positive opinions and negative ones too.

coolant is non-mixable type coolant containing some ehtylene glycol,kinda like running straight coolant which raises engine temp, and we all know a thicker fluid also creates engine drag thru the h2o pump.

the pros- life long coolant,non-corrosive,does not contains borates known to damage seals,higher boiling point...although it'll raise normal operating temp a bit.

cons-?

... this fluid has a slick feeling to it like brake fluid. which leads me to question...is it just basically brake fluid? there are some glycol in its ingredient, and therefore, some of my high performance brake fluid leftover, i just simply dump into the radiator...(no harm) as if left there, it'll absorb moisture anyways.

in essence, this has same characteristics as silicone brake fluid. higher boiling point, non-compatible...etc.

If i remember right, you need to completely drain all fluid from your system and use another product to remove the last traces of moisture. Evans is not at all compatible with water.
Also this fluid expands a lot meaning you have to go zero or low pressure in the cooling system.
If you were racing a high rev motor or turbo rotary this may be of use, other than that it's really not necessary.

marc? not many ppl replied, so i'm guessin ur the cat thats running this... nice tip. but i wass also interested in the pros and cons of this product. as i'm very fond of its nature. i hope i was somewhat close to the basis of how coolants or liquid rather in your heat exchange system. i'm thinking it makes more sense to look at it as a second oil cooler. since it being thicker in viscosity, therefore retaining more of its heat. and secondly, would be more difficult to move along its system, giving more resistane to the h20 pump...not favorable in every applications...as we all understand that pure water is the lightest and transfer heat the fastest.

my biggest concern is how much benefit would this be if my plans was in the future to turbo a rotary motor and use this product...what are its performance nature and its reliability factor, and does all of its pros outweigh its water/coolant counterpart?

sorry i didn't stay to debate last night as also i couldn't steal u away for the whole night just to have u cover all bases on this with me.
all ur knowledge and expertise on this special product would be greatly appreciated. (i'm one of the first asian kid there last night wearin a corduroy shirt)

re: evans is not at all compatible with water.
i was well aware of that explanation after i've touched the product. i immediately associated that explanation to cooking oil... it does not like water touching it as it'll immediately vaporize it.
makes every bit of sense! here's my thoughts on it so far.

EVANS: another fancy lubricant, used to dissapate heat. only in pure form. like that of dot5 fluid. am i wrong?

That Evans coolant is interesting stuff, but I've heard mixed reviews by people who've tried it. I'm intrigued by the stuff, but I'm too chicken to hang out on the "bleeding edge" and try it in my car.
