Does Water Wetter actually work in radiator and or supercharger?
Contemplating trying to reduce internal engine temperatures here in hot Florida weather.......so am wondering if the product Water Wetter can be used to any degree in both the radiator and or Supercharger to reduce the normal 200 degree temps I see daily on my temp gauge under normal slow driving conditions? If it is worthwhile, approximately how much of it should be used in conjunction with normal engine coolant? Will it also reduct temperatures in the Supercharger unit? Approximately how many degrees will or can it reduce normal stock engine temps as the Z06 comes off the assembly line?
Change your thermostat, program your fans to come on at the lower temp, and ditch the 50/50 coolant mix for pure water. Then add the Water Wetter. Not because it helps keep the car cooler, but because it has an anti-corrosion package in it that you need when running pure water. Your car will thank you.
I used to drag race a lot and in addition to the above mods I had an electric water pump and a manual fan switch on my 96 impala. In addition to helping at the track, turns out the electric water pump and manual fans helped A BUNCH in traffic. Stewart Components has an auxilliary electric water pump that you can install inline to help your stocker when engine speeds are low.
Short answer: yes. Pouring a bottle of Water Wetter into my cooling system reduced engine coolant and oil temps by 10F, no other changes (2014 M7 Z51).

Correct, but ditch the 50/50 coolant for pure water , cooler stat, reprogram the fans to come on sooner and like the other post says, you will see a big difference with the water wetter.
Why are you worried about 200 degree engine temps? That’s what it’s supposed to be.
Truth! If I see engine or oil temps anywhere sub-200F during normal driving in happy. On my 2014 Z51, the Water Wetter, Z06 grille, Z06 600W radiator fan, and heat-wrapping my radiator hoses have allowed me to achieve that.
When riding HARD on the car today (multiple back-to-back pulls deep into 4th) in 100F+ ambient temps with the A/C on my coolant never hit 200F and my oil stayed under 225F.

Just so you know. C7 uses a 60/40 mix. 60% water/40% coolant. From the Service Manual:
Use a mixture of 40% DEX-COOL coolant and 60% clean, drinkable water. If using this mixture, nothing else needs to be added.
This mixture: . Gives freezing protection down to −28°C (−18°F), outside temperature. . Gives boiling protection up to 129°C (265°F), engine temperature. . Protects against rust and corrosion. . Will not damage aluminum parts. If ambient temperatures are anticipated below −28°C (−18°F), make sure a proper mixture ratio of 50% DEX-COOL coolant and 50% clean, drinkable water is used.

it has been past 95-98 degrees outside and the Vette temps don't change. Oil at 220F or even 250F is not problem. Even with a dry sump the oil will increase with aggressive driving but well under what Mobil says is the max temp! 500F! I would not let it get past 300F for other reasons! If tracking in hot weather may need some extra help.
In the street rod with a 502 cid engine in a '34, I use 75% water, a 180 degree thermostat and water wetter. The water wetter does help with temps and corrosion! When idling, even with the electric fans tuned on (I have a 6 blade engine fan and two electric pusher fans that are thermostat and manual switch activated) the temp will rise. If idling I turned on the fans. If it is for an extended time the temp will increase to 220 F which is fine with a 15 psi system. Once moving the temps drop and I shut off the electric fans.
Not sure why people think the engineers at GM didn't push these cars in extreme heat to see what it will do? If you are not having a problem, why fix something that isn't broken? All those additives to me are just snake oil, Maybe Wetter works, but unless you are tracking your car or driving it excessively hard and it's overheating. You might have a point. Unless that's happening. I leave the system alone. Do the maintenance that GM recommends and just drive it. Most never clean the radiator that gets trapped with bugs and debris, all will contribute to heat build-up.

I live in the PNW where temps rarely break 80 and over 200 is normal. 219 or so for oil and engine is not unusual. Coolant hovers around 210. It it ain't broke, don't fix it.

Cooler water temps, less timing pulled, cooler water temps lessens spark knock tendencies and if you run 91 octane on our 11.5 to 1 motor's it pulls timing fast, cooler IAT's less timing pulled, cooler intake air is more dense more power. Look into the tune of these cars and see how quick the ECU pulls timing from so many perimeters. The trick is to prevent horsepower loss and fuel mileage.
