   Yes one stock cooler would not cool my coot so I installed two stock coolers and it works to good as I have to install a flap on one of the coolers for cold weather.

Well, to be honest guys, the stock oil cooler does not work that well.  Most who use it, including Tracy and Ed, have dealt with significant problems trying to cool their oil.  Both guys had to cut their first flights short because of high oil temps, and both eventually had to do significant tweaking of the oil cooling system.

My setrab by comparison has cooled very well from first flight.  The highest my oil temp has ever been was 192, and that was on an extended climbout at 32"MAP and 90 KTS - coolant finally overheated.  In cruise my oil temps run between 140 and 160.

The Setrab also fit better under the cowl, is readily available and comes with any size AN or NPT or Metric fitting you want to use.  They cost 2-3 hundred bucks - not cheap but not super expensive.

 
Dave, what's the part number of the oil cooler you are using? I'd like to look at it for possible future use. My oil temp will still hit 210 after climbing only 2000' on a hot day, requiring throttle back. If the ambient is below 75F or so I can climb full power to 10,000' and oil temp won't exceed 210. If I make changes in the future to increase power output, I may need to improve the oil cooler.
