Their website says this:

DYNO TEST RESULTS
Dynomometer tests performed by Malcolm Garrett Racing Engines showed significant improvements in coolant temperatures using WaterWetter®. These
tests were performed with a Chevrolet 350 V-8 with a cast iron block and aluminum cylinder heads. The thermostat temperature was 160°F. The engine operated at 7200 rpm for three hours and the stabilized cooling system temperature was recorded and tabulated below:
Cooling System Fluid Stabilized Temperature

50% Glycol/ 50% Water 228°F

50/50 with WaterWetter® 220°F

Water 220°F

Water with WaterWetter® 202°F

These numbers are similar to the temperatures recorded in track use and heavy-duty street use.

I have not observed an 8 degree decrease in coolant temperature in my 50% coolant/50% water mixture. I understand that the effect is greater when you're running straight water. My Spec E30 will have water and WaterWetter in it. My point was that this may not be the most effective use of $9 in a daily driver.
