No longer in KY
Very true. I'll research the aspects of leaks on a low-no pressure cooling system but you have a good point. If you develop a leak on the road you'd mess up the whole deal with water.And then you develop a leaky hose, wp, or radiator. It's not lifetime after it leaks out....
Well, keep an eye on the thread. As always I'll be posting far more information than anyone wants.Yeah was at work and service was off and on. Lagged post lol.
Edit: May consider this for my upcoming rebuild.
Thanks for the additional info. Your mods appear to be well-thought out, and effective. I didn't find the radiator picture you reference, I am curious about how it could add 50% to the system capacity, and fit in the available space. I did see the Evans thread at 3si.org, and browsed through a portion of it- It's the same back-and-forth about Evans we've seen on dozens of different enthusiast-vehicle boards.
I've reviewed your application with Evans' technical director, Dave Wright. We agree that a change to Evans coolant will not itself accomplish what you're after. The system as-is seems to be adequate for the purpose. More system capacity (i.e. your new bigger radiator) is never a bad idea. At the lower-than-OE-spec temps. you seem to be maintaining, (even under extreme load), there is not so much vaporization of water, so the 50/50 coolant will do the best job, strictly in terms of heat transfer.
You can't expect the outgoing coolant temp to not reflect the increase of heat in the heads under boost. Evans will readily absorb the heat, with control, as I stated yesterday: That is not a promise that it won't get hotter in the process. I have attached a document you may find useful. Please review at your convenience.

If you guys haven't read the pdf I attached above, you need to. And you need to use it in every "overheating" thread you see. It's that important.If you want to do an unsettling experiment, put some in a pan with a candy thermometer in it. Looking at completely motionless liquid at 300 degrees when you know it should be boiling is kinda freaky. It's great stuff and it works as advertised 100%. I probably wouldn't drink it though, it smells coolanty.
