What I found was somewhat surprising. I found that the coolant rads (2 Ford evap cores plumbed in parallel) had a delta T of 20C, while the Oil cooler only had a delta T of 5C. At first I felt this was OK as I remembered that the GM cores also gave 20 degrees delta T, then I as I was about to type this up I remembered that it was 20F. So this means that I am getting a delta T of 36F. 

 

The oil cooler is a little disappointing to have only a Delta T of 5C or 9F.

 

The EWP continues to function perfectly.
