Villi,
Your comments are right on the mark.  Many builders focus on the inlet side of the cooler and neglect the outlet conditions.  My 9 vein oil cooler is mounted in front of the #2 cylinder to take advantage of the pressure differential across
the engine.  I actually had to restrict the outlet to about 4.5 sqin. because it was flowing too much air in the beginning.
