Paul,

Does the wedge shaped diffuser require a trumpet shaped diffuser in
front of it, or can is it effective alone?

It is stand alone.

BTW Here is something you might try in front of the engine.
Four cores 10" by 10" by one inch thick.
Plumbing is rather complicated however.
All four should be plumbed in parallel. Big tank on top and bottom.
It should come out to be about a one foot cube more or less.

Weld the cores to the bottom plate of the tank first.
Then weld on the top plate. The top plates will need external
stiffening ribs as 30 psi will pooch them out for sure.

I don't know where you will find a 10 inch square coolant core but
oil cooler cores might work OK for coolant. If you make it
five cores one could be the oil cooler. You might have room
for six cores side by side. Less marginal.
