Hi Guys

I'm about to construct the diffuser for the water exchanger.
Can some of you guys with operating setups critique the design please.
So it consists of a K&M diffuser followed by a wedge.

And a happy Christmas to you all.

Change the 5.75" dim to about 2 inches.
The idea is to keep a constant cross sectional area duct up to
the K&L wedge diffuser. That minimizes the tendency to get wall
separation in the duct due to a drop in pressure.

Also raise the core in the cowl as far as you can.

It would be less risky if the core was 19.5" instead of 17.5 long.
It might work at 500 cubic inches but 600 cubic inches would
be better. Check out pick up truck cores.
