Bobby;
I have those same charts. That oil side
drop is measured for oil at 250F; and my notes say SAE 10 – don’t
recall where that came from. It’s been a long time, but it seems I translated
that to the 20W50 I was using at the time; and to 220F using some viscosity
data. That led me to the 20-30 psi number. Actually the MoCal was
better than some of the other coolers I had looked at.

Charts
One of these charts show
oil pressure drop for the C43- series. The C43-330 shows about 11psi drop at 15
gpm. It also seems the larger coolers have a better pressure drop to volume
ratio. I have no idea if the charts are accurate. I email Laminova and ask for
oil flow and pressure drop data for my ECD54-329 double core.
