Lets stay focused on the real problems.
A tiny minority of people are going to consider changing
the stock Mazda water pump. The benefits if any are
just not there.

What we don't know is:

A: What is the water flow through various types and sizes of radiators?

B: What is the water temperature drop through the various radiators?

C: What is the increase in temperature of the air flowing
through the cores?

D: What is the volume of air flowing through the cores?

This will help us design low aero drag, efficient cooling systems
that work well under all conditions, are simple to plumb and
that are extremely reliable. The last point is absolutely
essential for aircraft use.

Ed and I are working hard on B and C. Bill and Don are working
on A and D.

Correction:

Bill and Don are working on A.

I have already built a  test rig and gathered some data for D.
