Paul,

Merry Christmas to Paul and all!

I'm still chipping away at this cooling challenge.

Here's what I've got so far trying my best to stay within the cooling
principles in your book.....Horizontally folded cooling core (see core
size (Large).jpg attached)


Q1: Considering my design, what size cores would you prefer?

I can use 2.25" cores which would give me a total water cooling of 720
cu ins (13.33" wide x 12" tall x 2.25" thick x 2 cores) and total oil
cooling of 258.5 cu ins. (right beside the cooling cores) (11" x 5.875"
x 2" x 2 cores)

Or, I can use 1.5" cores which would give me a total water cooling
of 480 cu ins (13.33" wide x 12" tall x 1.5" thick x 2 cores) and total
oil cooling of 258.5 cu ins., same as above (11" x 5.875" x 2" x 2 cores)

The 2.25" core option has plenty of cooling and plenty of drag.

The 1.5" core has very slightly more cooling than the RX8 car.


Q2: Does the plumbing in the design look satisfactory for a parallel system?


Q3: I see that most radiators have the inlet and outlet ports diagonally
from each other, however, some radiators have it on the same side. Does
it make any difference for my design?


And, as always, I'd appreciate any other comments on the design.

Thank you very much,

Q1 go for max cooling. 2.25 inch cores.

Q2 is not good. You may get next to no flow in the top core.

Q3 Diagonally insures a equal distribution of hot water.
