Have you considered using a Laminova type oil/water exchanger?  They're
relatively light, compact, work well, and come in a variety of sizes.

I once tried a large oil to water cooler sold by Callies Crank shaft
company. It was about 20" by9" by6" thick. It worked great. Oil temps
dropped to within a few degrees of water temps. But then I could not contro=
l
water temps. So I suggest that it is very hard to beat a oil to water coole=
r
for temperature transfer.

That is just not a question. It works great. But you must then increase
water to air cooling capacity by 1/3 or more to maintain coolant temps in
the green.
There is only air cooling no matter how you go about it.

The oil to water cooler was also very heavy when full of fluids.

I used an air chisel to remove the water jacket from the oil to water
cooler, and used it as a oil to air cooler for the transmission oil. It is
still in the car today.

Something as simple as an aluminum tube through a radiator tank can take ou=
t
a lot of heat from the oil.

Most automobiles have a few loops of tubing in one tank to cool the
automatic trans fluid.
