RE: Engine Ice VS Liquid Ice

I asked my local yamy dealers and they never heard of it and won't try to get it...

Clark quick question do you think a higher boiling point is really a good thing I have been looking at different products for better cooling, but I have concerns about raising the boiling point because hot is hot and it would be the same stress on the engine. I am beginning to think aftermarket radiators may be the best option and do we really gain any benefit from additives, has anybody done any testing to see if they are a benefit.
I have in my two of my personal bikes. an 03 YZ450 and my 06 WR 450. I do not have quantitative numbers but I do have qualitatitive positive results with a home made mix.
search Coolant Recipes.

When coolant reaches its boiling point, it can no longer cool the bike by absorbing heat. So a higher boiling point means more heat absorption, i.e. better cooling properties ...SC
So you're saying pure EG coolant which has a much higher boiling point than water has better heat transfer cooling than pure water?
If you are, that is absolutely not true.
The best heat transfer properties on the planet for engine cooling are pure water. Now, it doesn't have the highest boiling point, even in a pressurized system than coolant supplements, but it does transfer heat VERY effectively.

Well, if we're dealing in absolutes, then yes, pure, non-diluted coolant doesn't work as well as plain old water. But we're not dealing in absolutes, we're dealing in product that is ready to go out of the box. If you want to split hairs and talk about the extreme ends of the spectrum, we can poke holes in everything...After all, pure undiluted frozen orange juice concentrate has more vitamin C by volume in it than the stuff in the carton, but it tastes like crap ...SC
Orange juice? Why a red herring? This isn't even debatable man.
We're dealing in science. It's all very testable and there's no mystery once you understand the terms.
Heat capacity is the one were all interested in. Water is 1.00 cal/g-C', everyting else on the planet is less. If you want to reduce your chances of boiling over, you can.
Read the paper. I did and I've noticed a huge difference in my coolant systems performance by using this formula I read about in this thread....

Theres enough info in that linked thread to make some good choices.

So to get back to Clark's point, for MX racers this may be great, but us woods, trails or desert riders may find the need to trade off higher operating temperatures for coolants that don't boil off.

to quote moderator Greyracer513 from your linked thread "Boiling water can't cool anything".
I agree, the linked thread is a good one to read.

If product A boils less readily than product B, then product B will work better, that's not debatable. ...SC
That is highly debatable

That is highly debatable
Ooops, I didn't proof-read that, I meant the other way around (I fixed it). Good catch! ...SC
