Coolant Additive / Water Wetter

I've run this in the past in other vehicles. Since the Supra has a low temp cooling side for the AC and Inter-cooler, I was wondering if this would be a good add in. Or if it's verboten in our cars because BMW used some space age German engineering that would gag and die if it came into contact with this stuff.

I’ve used this on KTM motorcycles (and
That’s German ) I’d like to know the
Answer too.

I use to use it in a prior corvette.

Bump?

What problem are you trying to solve that's not already solved by the BMW coolant?

Likely drag strip racing. Most strips don't allow coolant and require water only or water wetter.

Never in a car but ran WW in conjunction with distilled water in my track bikes due to track/organization requirements.

Not only that, but distilled water mixed with Water Wetter (or Rislone Hy-Per Lube SuperCoolant, or AMSOil Coolant Booster) is definitely superior in terms of thermal transfer efficiency. It's a win-win.

Wow, I haven’t used Water Wetter since the 90’s.

IIRC, the science behind it is that it’s basically a surfactant that breaks the surface tension of water, so it helps prevent hot pockets of steam from forming in cavitation areas of the cooling system.

If I’d have ongoing rising hot temps above normal, then it’s something I would use.

Ah! Excellent question.
And no - not a drag strip. She's an every day driver that we drive once a week because of WFH in the post C-19 landscape.

I live in AZ. It's hotter than a MOFO here. Summers get to 120 and pavement air (which the Supra sits right down on) is even hotter. Just looking to treat the car right and give it a little advantage in a hot environment.

I haven't experienced it yet but I'm guessing that in Germany they don't build an AC that tackles an AZ summer with ease. Maybe this would help with that getting the heat transferred out of the engine or on the low temp side.

My Ranger Ecoboost has heat soak lag in the hot parts of the summer. So that's my frame of reference.

Have you been to Germany? There are days that are over 100F there and humid.

Most major car companies do hot weather testing in deserts around the world as well.
