I have not experienced this issue, but I also don't race my SE on a track. Nor do I plan to.
I have had some spirited drives, but apparently not the kind of "sustained hard driving" that results in reduced power. That just isn't feasible (or safe or legal) on public roads where I live.
I have seen reports by a couple people who have participated in autocross events in their SEs and did not have any overheating problems. But autocross courses only take a couple minutes to complete, with more than enough time between heats to let your car cool down.
I have also seen some people report reduced power when their SE is cold-soaked - sitting outside overnight in freezing temperatures. After driving for about 15 minutes, things warm up enough for full power to be restored.
And I have seen reports by some people who live in hot climates, but have not experienced overheating or reduced power.
As long as you don't plan to use the SE as a track car, you probably won't run into this problem.
