When you shut down a hot engine, there is still a lot of heat left in the
metal parts thereof, but the coolant flow has stopped. The left-over heat
dissipates into the coolant and raises it's temperature. That's why a lot of
cars won't overheat until after they are shut down, then they lose a bunch
of coolant out the overflow.
If there is any significant cooling effect available after landing with a
hot engine, it would be good to idle into the wind for a few minues to get
rid of some of the excess warmth. Might also help to keep from coking your
turbo bearings.
Keep going, Mr. Slade, I'm hanging on your every flight report.

The cars, especially the 13Btt do the same thing. Heat soak-I added a temp
gauge that reads in degrees on my car and it goes over 226F easily if you
let it-then the electric radiator fans come on. I added a boat blower in the
engine compartment on my 94 rx7. One will go in the plane as well........
