I add= ed a Laminova oil/water exchanger.  It is connected to the coolant ret= urn line and in series with the oil/air exchanger.  I measured a = 10* increase in coolant temp through the exchanger.  I haven't me= asured the oil temp drop yet.  However I estimate the oil te= mp drop through the exchanger to be 20-25*.

All sounds good.  I also have a Lamin= ova H.E (C43-330)., and after down-loading the performance charts, and look= ing at the flow/pressure drop data; I chose to plumb it in parallel. It is = designed for typical piston engine oil flows, and will give some pressure d= rop in our rotary use.

At 6000 rpm (about 15 gpm oil flow) they show 10-12 psi drop with oil = at 250F. Don=E2=80=99t know what it is with oil at 150F.
