As was stated above, water does the best job of transferring heat. Yet, It has a 212* boiling temp. Coolent on the other hand, has a much higher boiling temp (don't know the exact number), yet, doesn't transfer heat very well. That's why usually going with a 50/50 mix is your best best. My personal experiance though, with a 3rd gen Trans AM, (NO air flow in front, just what get rammed in from the air dam) I ran 1 bottle Water Wetter, 20% coolant, and 80% water. My thoughts, more water, better heat transfer. And just enough coolant to help raise the boiling temp, with Water Wetter to help with the heat transferr. Well, in 105*+ days we have here in Phoenix, I kept my TA around 200*, in stop and go traffic, with the A/C on too. Hope this helps.
