[s-cars] Water Wetter

[Larry]

If you read redline's instructions for water wetter, once you get even remotely close to your typical 50/50 mix of EG and  water, water wetter will do nothing. Not sure what effect EG does to surface tension, but since 50/50 has nowhere near the same heat capacity as pure H2O, not sure it matters much. Pretty much, RL WW is intended for pure H2O cooling systems (usually track cars) otherwise a waste of time. OTOH, I've always wondered how well the Evans 100% EG coolant would work with a turbo car, now that they've gotten the viscosity down to water like cP. It's advantage is supposedly more even head temps at the expense of higher overall temps when you're working things hard (otherwise it's supposed to run cooler). Don't know if that would work to a turbos advantage or disadvantage. I know it can help an aspro.
