My O-360 powered, constant speed prop RV6 has the oil cooler behind the left rear cylinder (like about 2000 other Lyc RVs). I have the oil cooler 2/3 blocked for cool weather flying and it still will not get over 175 degrees unless I am doing full stop and taxi multiple takeoff and landings. 1000' per min climbs from SL to over 10,000' on a hot day are no problem for oil or cyl head temps. The temp gage probe has been tested with an accurate thermometer too. The Lancair inlets should be more effecient than the RVs too. I think the secret is very tight baffleing, caulk the gaps around everything with high temp silicone, poke an inspection mirror in after the top cowl is on and imagine the plenum as a pressure vessel. It is well worth the time and effort since it not only gets you cooler oil but reduces cooling drag.
