I will have to look for this article in my June issue.
There is an optimum flow rate for every radiator -- not too fast and not too
slow. This rule also holds true for heat exchangers in power plants.
The ancient practice for TR-3/4's was to install a restrictor washer in place
of the thermostat (opening, about the size of a quarter), use about a 15 psi
cap, and eliminate the bypass flow. All of the open areas around the
radiator are then shrouded off with sheet metal or aluminum. The overflow is
then connected by tubing to the top of a gallon lacquer thinner can (catch
tank with a small vent hole in the top).
I am sure that some of the list now have a better system than the one above.
I hope to eventually get an aluminum radiator.
