Ed;
There are two things going on-- coolant flow rate and block coolant
pressure. They are inter-related in that as the flow rate through the
system increases, the back pressure in the block increases as well. This
back pressure is due to the coolant's being forced through a
restriction-- a thermostat or restrictor plate. Remove this restriction
and the coolant flow will increase but the back pressure drops. This
lowers the boiling point of the coolant in the heads & block, allowing
hot spots to develop. You need both flow and backpressure which requires
a very good water pump. Check out the Stewart website.

I was going to answer Ed with that, but you beat me to it. I used to
work
on large diesels and was told at one time that a Cummins had 40 lbs of
pressure under the thermostat from the water pump. Goes with the post
about
pressure not flow.
