Water wetter

Does anyone use a water wetter or some kind of additive like purple ice for there track / turbo car?!

If so what do you use and did you notice the difference as some are meant to help with cooling hot spots?

I do I do.. but not driven the car yet so can’t comment on the benifits ? got from eurocarshite. Sound legit

What did you go for from there? I know there is a few choices out there on the market!

Coolant is an interesting topic.

Counter-intuitively, distilled water without an additives has the best heat-carrying capacity. It's not used because most modern engines have different metals in contact with each other (eg, alloy head and cast iron block, or alloy engine and head with cast iron cylinder liners) and plain water will cause galvanic corrosion between the metals really quickly. Coolant additives are needed to prevent the corrosion, but they actually reduce the heat carrying capacity.

That is the one new thing I am going to learn today!

That's why a lot of race cars run just water with a bottle or two of WW or something similar.

Most of our racers only run about a 25-30% antifreeze/water mix because that gives most of the cooling benefit but with decent frost, etc, protection - so we don't crack a block overnight in parc ferme in winter.

Also note that the standard coolant corrosion-inhibitor additives INCREASE the boiling point, so plain water can carry more heat but will boil sooner.

I used to use water wetter in my modded integrale, it made a noticeable difference to running temperature, back in the day when gauges showed you the actual water temp. Be warned though, it is extremely good at seeking out weak points in your coolant system, especially if you have silicone hoses, so you could be more likely to spring a leak. I ran a higher pressure system with rubber hoses and had no problems.
