One issue may be heat transfer capability, which they don't really talk
about except to say that NPG+ is 32% better than NPG.  The main reason you
use water/glycol mix in a cooling system is that water has a lot of heat
carrying capability, much more than glycol alone would.  Race cars run
straight water, sometimes with a little bit of wetting agent added, for
exactly this reason.
