Rob -

I will try to provide some data, but at this point my experience is limited.
(less than one hour of total flight time).

Details of installation:
Lycoming IO-360, turbocharged (oil cooled turbo)
single Positech 4215 oil cooler
ducted from baffle behind #3 cylinder, vented to open area behind engine
Engine plenum configuration

I have experienced oil temperatures that are TOO hot, even on cold days.  I
have just completed a modification to the oil cooler setup that I hope will
improve oil temps.  Modifications include dedicated 3" NACA duct air inlet
to a larger (Positech 4219) oil cooler.   NACA is on copilot side, about 2"
below the junction from upper to lower cowl.  Also has a dedicated outlet
that is the reverse louvered gills on the upper cowl.  

I'll post how it works (or doesn't work) after it has flown...

Matt
