Proof that Water Wetter Works

[TR6oldtimer]

Water Wetter is the racer's edge and in my opinion will do little if anything to improve engine cooling in non-radicalized TR engines under normal operation. The percentage decreases in coolant temperatures cited by Redline were derived from a three and half hour dyno test on a v8 running at 7200 rpm. (A speed and duration most of us will realize only in our dreams) Water Wetter claims to reduce the effect of steam bubbles created on high temperature spots in the engine that occur under extreme operating conditions. Given steam is an insulator, any product that can reduce steam bubble creation will enhance heat transfer, lowering engine and coolant temperature. The product works by reducing the surface tension of water, which in and of itself will not stop the formation of steam bubbles, but allow the formation of smaller ones. The smaller bubbles collapse faster, thereby allowing more coolant to come into contact with the engine surfaces.

So unless you are running a 250 HP six, as far as I am concerned anti-freeze and water works fine.

Here in sunny Florida where freezing is never a problem and overheating is always a problem. I run an 80/20 mix of water-AF and water wetter. I also run two electric fans. I figure the 8 bucks is cheap for the little extra it does.
