Hi Paul...

I've been thinking about the cooling problem that has been discussed daily
since I'm been reading and following along.

In theory, using the calculations to determine the correct water and oil
cooler size, should be working.  It seems that the reason for thin cooling
vanes is to help the airflow through the cooler.  Here are a couple of ideas
I wanted to through out to help with the cooling problem.

Wider spacing between the core tubes, double to test.  This will allow more
air to pass because the boundary air around each fin is restricting air flow
through cooler.

The second idea is alignment of the airflow before and after the cooling
core.  Because the airflow is bending and changing direction, the air becomes
stagnated by internal vortices.  Try using a spiral device to help align and
rotate the air.  This device will looks like a grain auger from the side
view, but is very thin, no moving parts and will increase the velocity of
flow by aligning and rotating the airflow.

This concept could also be used on the intake to increase the velocity of air
flow to the rotor.
