Mark,

I’m going to investigate that further  but first look seems like a winner if it can handle the BTU loads (which does not seem like an issue.

 

I like the idea of a single scoop as well as a single radiator if it can be done. I’m thinking airflow here.

The P-51 scoop is supposed to create enough thrust as a result of the heated expanding air jetting out the back to cancel out 90%+ of the drag created. I never could get my head around the whole ram-jet theory but that’s the basis.

 

The other benefit I see here is the comment provided earlier about the optimum oil and coolant temp being closer to the 180F range, both of which I could control with my coolant thermostat.

 

Like I say, I have time to work these things out.

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