I just read that some of the Subaru guys are using NPG+ coolant.

I just had a chat with Dave at Evans. It sounds like this stuff might be
helpful, plus these guys also make reasonably priced custom radiators.
Dave
was very knowledgable concerning the problems of cooling an "off-road"
vehicle, especially when it's a pusher :)

Anyone using or know anything more about this stuff?

It's all on their website.   Note that they recommend a higher capacity
waterpump on engines run at high output.  This is due to 2 factors.  Higher
viscosity of the Evans coolant and the lower specific heat of the stuff.
