I use WaterWetter in a Jetta GLi that has high compression, a chip that has
advanced the timing curve,  and a knock sensor.  In this engine the stuff is
wonderful.  The less knock the sensor sees, the less it backs off on timing
and the more power the engine makes.  I don't think that it would be as
dramatic in a WBX.  My understanding of how it works is that it raises
"thermal conductivity" meaning the coolant can carry more heat, and it
raises the localized boiling point (at the hottest places in the cylinder
head).  Without it, the hot spots cover themselves with a layer of vapor.
This keeps the coolant from getting to where it's needed most, and allows
the hot spot to get hotter. In performance engines, this means knock.  Some
say that if WaterWetter is doing it's job in knocking down these hot spots,
the coolant temp will actually go UP, as it's now transferring more heat to
the radiator.
