What is wrong with these cooling system

designs?

Paul,
 If the question wasn't rhetorical, there is

no

diffuser prior to the face of the heat

exchanger.

The turbulent entry and "dead" corners will

reduce

the effectiveness of the heat exchanger. Better

would be to angle the heat exchanger and use

the

wedge style feed with a diffuser tapered to meet

the

intake.

You also get a B Bill :)  To be fair there is

some

subtle factor that just
recently crystal clear to me again. Hint it

affects

air cooled engines as well.

Good point Robert. Constant torque hose clamps and
silicon rubber hose should be used.
Still not what I had in mind.

True enough and that is one of the major drawbacks to this arrangement.

Well we are kind of stuck with two inch thick cores under the engine. Thinner would be better.
Most cores will be 20 by 16 inches or 320 cubic inches per inch of rad thickness.
The oil cooler is mounted along side and is about the same length. The oil cooler 
is about two inches thick roughly. There fore it looks like we are stuck with two 
inch water cores.

Now you could do something like this with thinner  water cores.
