On a WR you boil over into a catch bottle. As it cools it sucks the coolant back in. So you don't lose much at all. Evans does not boil over but it also does not transfer the heat as well. So you run hotter and never know it. The simplest way would probably be to run evans. ..but I don't think that's the best. I rather the level of heat be dealt with..but it costs a lot more and lots may not want to go the route of.. bigger radiators, bigger impellar waterpump, overflow bottle, large volume coolant head, inline aluminum radiator hose coolers, higher pressure radiator cap and a variety of water wetters or special expensive coolants, and of course radiator fan.. There's also two2cool oil coolant additive too for that matter. ..and of course jetting . ..but maybe one could choose some of those mods and that would be enough.. say a rad fan and an overflow bottle..to start and then if it doesn't work well enough keep adding mods till it does.
