It is well known that adding anti-freeze to water will reduce the heat transfer ability as compared to 100 percent water.
Most racers will reduce the percentage of anti-freeze in their coolant mix, or run no anti-freeze at all. That's what I do in my track car. But if you run straight water, you need to add water pump lubricant, which is also what I do.
My take is water wetter's advantage is only if you reduce anti-freeze in your mix. My guess is you can get the same advantages more cheaply by running distilled water and water pump lubricant.
Having said that, I'm no expert and there may be something Redline is doing I don't know of. I do run their products in my transmission and rear-end. The watter wetter is not going to hurt anything, I would be pretty sure of that.
If you read Redline's brochure, they are basically saying Water wetter will let you run less glycol (anti-freeze), help lubricate the water pump, and reduce scale from hard water. I think you get all these things if you run distilled water and what probably is cheaper water pump lubricant. (Water pump lubricant you normally get from your anti-freeze mix.)
