This question came up more than 50 years ago in the age of Flathead (wrought
iron engine) powered dirt-track racing in stock cars and sprinters with
heating problems. One cure was a washer restrictor to slow down (?) the
flow. Everybody thought that was the reason, and it worked. Later we found
that the stock water pumps were cavitating (creating bubbles) from being
wound so tight and the washer increased the pressure on the pump and reduced
the tendency to cavitate. The bubbles reduced the contact of water to
wrought iron and caused real hot spots. Other cures included modifications
to the pump to reduce cavitation.
Today's water pumps surely must be turning RPM's beyond their design RPM
and restrictors may be doing the same thing as they were doing 50 years
ago- reducing cavitation.
