Interesting analysis of Evans...
http://www.3si.org/forum/f11/dumping-evans-coolant-go-back-conventional-setup-206021/

highlights:
1) A car will run cooler with straight water + water wetter.
2) Evans is 100% propylene glycol. This means it has great boiling capabilities (doesn't until 360F compared to 212F with water) but has a much lower specific heat... meaning KG per KG, it will hold approx 60% the heat that water does... so your radiator will seem like it has "shrunk".

Interesting analysis have been done by nerds who use water to cool their PCs.

I've used it and I don't anymore in fact my dad became a dealer and none of us use it anymore. Very expensive as you know,it turns a brown color and gets kind of slimey and coats everything in the system with a brown layer. I was using it in a diesel (7.3 ps) and it's supposed to be great for them but my coolant filter looked like it had cast iron pieces in it from the coolant boiling on the cylinders. They claim this coolant is excellent for preventing this without the additive. I used the clear racing stuff in an Ultima GTR I built(midengine 383ci)and that seemed to work very well but it's not good for a DD and has a short lifespan. Mike





has anyone ever used this stuff?

it sounds good, but i am wondering if there are any issues, other than cost.

yeah, i suspected that there would be a downside, but never having used myself, i figured i would ask.

Everyone uses water for pc's these days; real Nerds use Liquid Nitrogen, with Liquid Helium.

Last I heard, the record overclock is over 8GHz; not bad for a ~$500 processor. :) EDIT: This is still the record, after a brief search...

Everything other than water is not a really good option for cooling cars; our cars need more cooling as it is, thus the popularity of the Cobra radiator mod.

(I finally understand RaceCougars' comment about "turn the brackets over...; that works great, with some adjustment.)


PPG is not a good coolant, IMHO; it's only benefit is that it is non-conductive if pure, there's no corrosion from aluminum and steel parts in water.

That "If Pure" part is the hard part to achieve. :)

I have to admit, Liquid Sodium cooling is much more efficient; but that takes "Radiator Leaks" to an all new level. :thumbsup:

It would almost be worth it to see some idiot add water to it hot... or stuff a screwdriver thru the hose, lol. (Interstate mechanics...)

Years ago they would just put straight anti-freeze without the water or 75/25 mix with mostly antifreeze and it did the job well.

That can work; but the cooling is about half as effective.

Nothing cools like water, in our operating range.

De-ionized or Salt?:D

Molten salt actually cools better, as does liquid sodium; but the temperature range is a bit high. :thumbsup:

I think the guy that owned my Red Cougar used salt water as coolant; I've never seen so much crap...

How's the interview go? :)
