With and without 3rd radiator, with and without BoxsterS water lines. With and without standard coolant (with/without water wetter)

I *know* you know better than to read the gauge for this. Show me


We are racing. I have steady state consistent lap times in all sorts of different weather. I'm suspecting what your seeing only pertains to certain circumstances.

Whats your results from using water wetter? I've always wanted to try that stuff, but that was around the same time I experimented with marvel mystery oil

Water wetter, or what ever brand name you choose, is just a surfactant mix to lower the surface tension of water. If you are using a water/coolant mix, it is unnecessary as the coolant already carries similar capabilities, and not all of the commercial products maybe compatible with Porsche coolants.
