>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.

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.
