Jerry,
Unfortunately what temp your 582 runs is more a function of
your cooling system than anything else. Here in San Diego I anywhere
between 140 (thermostat opening) right up to 180. I never run over
180, which has lead to some fairly "comical" departure procedures.
Once out of Fresno with 115F on the ground it took me about 15 miles
to nurse my poor Kitfox to 1000' AGL, running the water temp right at
180F. Once I got up above the ground the temp cooled a bit and I was
able to climb more aggressively. When I put my machine together I had
to drop the radiator 1" to keep temps below 180F on the ground. I
find that ground operations dictate water temps more than flight. I'm
good to probably only about 95F on the ground. I get away with higher
temperatures by running high RPM's for better cooling and by shutting
down the engine whenever I can, such as when holding for inbound traffic.
In the air, when temps are in the normal 60's and 70's my
engine runs right at 140F. I really need to put in the 160F
thermostat that many people run.
