Waterless coolant- no pressure... no hose blow offs?

ncgt,
Did you notice any increase in temp?
Dirt bikes and karts have very small volume (capacity) cooling systems due to packaging and weight and are very sensitive to any extra energy (temperature increases).
Cheers

Everyone wants a magic potion or an easy fix for everything but there never is one.
Evans doesn't cool as well as water not to mention there's nothing magic about it just fill your hole system with sierra and you won't notice a difference between it or evans.
It needs a super high boiling point because it's getting super hot. As far as the transfer thing goes it goes both directions so don't give me the coolant is super hot because the engine is super cool.
In the rotary world people like it because there are iron and aluminum plates tied together in the rotary engine that expand and contract at different rates and it's believed that having a coolant that heats and cools evenly is superior and that's true BUT a properly setup water system will cool evenly as well and run cooler and your car will go faster.
Run evans then run water. You'll be a second a lap faster with water
Evans isn't the answer the answer is a properly setup cooling system because like everything else there's no short cut.

Very nice find. Another thing about plain water is it has problems maintaing contact with a hot surface, think drop of water on hot skillet, so the addition of a surfactant, such as water wetter helps in the heat transfer. I personsly prefer Pencool 2000 over water wetter as it is proven in Diesel engines to prevent cavation pitting of the cyl liner as well as preventing corrosion.

Evans is commonly used in racing in the US. I've used it when racing dirt bikes and karts. Cannot be mixed with water. Can purchase it directly from mfg or in various race oriented shops in the Charlotte, NC area as well as other race shops in USA.
Not cheap, but works extremely well.

Thanks and agreed localized hot spots are better with a surface tension reducer (surfactant). What's the make up of pencool? I'll have to check it out. Nice about water wetter as it's not really enough surfactant to make it super slick behind you if something does let go...

Pencool is not slippery at all and works by raising the ph of the water to prevent galvanic corrosion and reduces surface tension. Nothing wrong with WW but I don't have a lot of faith in it's corrosion preventing abilities. Caveat as I live in South Florida freezing is not an issue.

I switch mine out in the spring and fall between DI with WW and coolant for street driving in the winter...
