Everyone with oil temp issues

Right, but the whitepaper addresses that. In the test in the paper (not done by Redline, but by "Malcolm Garrett Racing Engines"), they ran a Chevy 350 w/ a 160 thermostat at 7200rpm for three hours straight in each of four coolant configurations and recorded the temperature the coolant stabilized at.

50/50 glycol/water: 228F
50/50 + water wetter: 220F
straight water: 220F
straight water + water wetter: 202F

There's no doubt that with or without water wetter, you get better cooling from straight water. I'm not willing to run straight water in my street car (although I may later move to 70/30 water/glycol), but it seems to have an effect even with a 50/50 mix.
