Evaporative cooling question
veggie:
On my latest project I was thinking of using and evaporative water tank for engine cooling. Just like the original Listers.
That project can be seen here ... https://listerengine.com/smf/index.php?topic=9572.msg109839#msg109839
While they do take a long time to heat up, once near boiling they keep the engine at the optimal operating temperature.
And warm up time can be controlled by the size of the tank.
I will most likely use a pump for circulation rather than rely on thermosyphon, although that simplicity appeals to me also.
My question to all those who use an evaporation tank:...
Do you mix glycol to the water in your systems ?
And if so, does the glycol boil off with the water or does the mixture get slightly more concentrated as steam leaves the system?

When I used thermosyphon on my twin I had thermostats on the water out manifolds.
I placed the bottom of the tank level with the return line to the engine.
A pump will not allow real thermosyphon action. It may work better in your application though.
I can't answer the glycol question but I would think the water would evaporate leaving the glycol
behind.

I did want to add that I have had great success with the after market "race" Honda radiators.
Usually about $100 or less on ebay with an included fan.
I have found on my projects that a 12" fan won't cool nearly as well as the 14" version.
I would put a thermostat on your project. Quicker warm up times amd more consistant running temps.
Good looking project !

32coupe,
Thanks for the feedback. I will see how I can fit a thermostat into the system.

Veggie- I've got a thermostat on one of my units (that is currently running off of tap water). Opens and closes as needed. BUT...I added a radiator bleeder off to the side of it, so that I could get water throughout the jacket before a start-up. I can take a picture if you wish. Just PM me.
On my main twin, I run 50 gallon hot-water tank, with the insulation stripped off. Strictly thermosyphon. Sure, it's steaming by the end of the day, and I add water about every 2 weeks. SHOULD the water level go below the "upper" fitting, the system simply turns into a condenser. Not a problem. Still works. Again, I can take pictures if you wish.
