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.

Laminova 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.
