I've improved my cooling quite a bit by installing an insert in the bottom of the cowl to direct air up and into the oil and water radiators.  This took the place of  the vanes I had installed first.  Attached is a picture taken looking into the air inlet duct showing the foam insert in the lower cowl/duct.  My last flight at  90 deg. OAT my oil went to 212 and the water went to 199 F.   This was at about 5200 rpm, 23 in. mp and 115 kts.  My oil pressure was 65 psi.  I'm using Castrol Synthetic 10W-30.  On start-up my oil will go to 85 psi max. From tests I've run, I now have more flow through the first 40 % of the radiators and less  flow through the rear 60 %.   I probably need to change the wedge shape to increase flow to the back of the radiators.  I'd like to review the document  by Kays and London that covers design of a wedge.  Does anyone have information on how I can get this document?   Also does anyone know if the inner combustion "O" rings used in the Renesis engines are Teflon encapsulated from the factory?  I
