I would say that if you enlarge your oil inlet to 38 sq inch and still do not get the relief from your oil temps that you might reconsider the use of the core for the oil cooler.  38 sq inch should provide plenty of air for the oil cooler. 
 
Thanks for all the info Ed.  My water core inlets are at about 48 sq inches IIRC.  The ducts are even reasonably well shaped, so that explains the fine performance of the water cooling. 
 
I'm still convinced that the evap core will be superior to the 2nd gen oil cooler, if all other installation details are equal.  Unfortunately, my evap core installation is less than optimal, but is probably better than a 2nd gen cooler could ever be in the space available.  With any luck, going to 38 sq in will give me more oil cooling than I need.  If I end up with too much oil, and water cooling, I'll just have to add that supercharger I've been looking at :-)
