912 rain shield and oil temps

It's been 85 to 95 degrees and 10 to 20% humidity here in the Denver area the last few days. 11% today and 90 degrees. On top of that I have been making runs from 6 to 11000 feet the last 3 or 4 days. Arvada then up I70 and over Berthoud Pass to Winter Park yesterday. Let's see, hot, no moisture in the air, and thin air to cool the oil, cylinders and heads down. The POLO engine has been running 210 to 230 degree oil temps. I took the rain shield off today and ran Coal Creek to Nederland to Boulder to Arvada today. It's a nice 1 hour quick run in the 6 to 9000 foot of elevation range.
The oil temps stayed in the 190 to 210 range the whole time. Heading to Steamboat Springs with a group Saturday. Looks like the rain shield will stay off till the cool of fall or when I run the coast between Carpinteria and Monterey, California.
If you are running a high hp engine and still have the rain shield on, you might try running without it and see what happens.
By the way the next oldest Porsche in the group is a 78 911SC. Most are 2000 and newer cars. As long as they keep it under 140 I'll be OK. I've been to 125 and there was a lot left to go as long as the car doesn't start hovering off the ground. I do love this engine.
