What do you guys think of this. NPG makes a waterless coolant that is supposed to cool better. I've heard the COOLANT temp gauge is higher, because its taking away more heat, but motor temps are lower. Would be a pressureless system. Sounds neat but expensive.
Waterless Coolant

I doubt that will work for our motors setup without heavy mods. IIRC you have to strip out all water from the system for it to even work. I wonder what the life expectancy of this coolant is? Isn't this only used in race applications and changed out each time?

IMO, it's really not suitable for a MK III due to the higher coolant temps...the ECU will pull timing over 210 deg F.

well I have seen this
The first thing that comes to mind is, water has one of the BEST thermal condutivity for any liquid out there. What this means is regardless of what marketing says, water is the best liquid to move heat away from an object. Everything else is second place to include NPG+
The only problem with water is that it is a good oxidizer.
Now if we could convert water into its steam form and back. That would be the ultimate in heat removal.

That's the biggest reason (besides freezing) you want to run at least a 50/50 coolant/water mix to inhibit rust/scale build-up.
I've been considering HOAT type coolant...appears to be superior to the usual EG based stuff.

Yes water is the best transferer of heat, the problem is that steam is a horrible heat remover.
Don't look at it that way...water converted to steam removes the max heat possible. Under high presssure, even more so. The problem is designing piping to handle the pressure and a condensor to convert it back to water...way too big (and heavy) for a car.
Are you talking about the aluminum overflow tanks?
If so, they are fine to use...most guys get one because a bigger IC won't fit with the stock tank. It needs to have the same capacity and be plumbed so the line from the radiator is near the bottom of the tank so it works like stock. You will lose the coolant low warning light.

As noted water is the standard on which thermal conductivity is based. There's a reason for that.
John: HOAT coolants are still EG based, they just don't use 2-EHA as part of the add pack. I'm pretty sure the newest OEM stuff is hybrid too but of the HOATs I think Glysantin is best. Another reason I like it is because it can be used in everything I own.

Thanks for the clarification JJ. I've been reading up on HOAT coolants...I thought that it was EG based, but that appears to be where the simularity ends. HOAT looks like it would be an excellent, long lasting coolant. I do know one thing for sure...Dex (OAT) coolant is one we don't want to use
I thought you used G-05?

I thought that the breather tanks removed steam from the system, if mounted high enough in engine compartment. http://store.jdm-spec.com/grtysrabrta.html
Also, what is HOAT/OAT coolant?

I do. Glysantin is the "G" in G-05:

I thought you were referring specifically to Zyrex G-05 vs the BASF product.
