Chris,
I just went to the evans website and was looking at all the tech specs, etc... Sounds like some really cool stuff! I noticed its specific heat capacity is significantly lower than water. Seems to me that this is the argument for not running a lot of
antifreeze in the hot months and just running water - it cools better. So to me, that would indicate that the water cools better than the Evans NPG. But obviously, they're on to something.
You say you think it's great stuff... Did you run a traditional Water/EG mix at any point? If so, what kinds of differences did you see?
Thanks,
JP
