I am saying that the harder a car is driven, the more likely it is to heatsoak. And further, that a pro driver puts significantly more stress on a car than the average amateur does. This should not be a revelation to anyone on this board.
The higher percentage of the time the car is on throttle, the more stressful things are on the car. The higher temps get, the less cooldown time is allowed, and the ecu pulls timing more.
Again, you can argue with me all you want, but I track a FI car regularly. Your statement that a 30 minute session at half pace in a FI car will show heatsoak is pretty funny, and blatantly wrong. I am running 1:43 on the mid-ohio club course on street tires with a FI N55 engine putting out 400whp. That is pretty fast on street tires, faster than any reported lap times in the M3 forum. I have never once gotten it to heatsoak at sea level, but I did manage to get it to pull power and go into a coolant limp mode when I was at Pueblo Motorsports track in Colorado due to the elevation. What this means is that my abilities are driving the car on the edge of heatsoak, and if a better driver than myself was to drive my car at sea level, it would likely heatsoak. I am just not fast enough to get it to do so. The exact same thing applies to brake fade, and numerous other things on the track.
I have been on ride-alongs and shared the track with professional race car drivers and the difference in skill between them and even talented amateurs is enormous. I read a post in the 1M track section a while back that had Pobst drive the OP's car at VIR. Through the esses, Pobst was 15mph faster than the OP with the identical car. That is 20% faster!
What you are saying is basically the equivalent of a softball beer league player saying, "How come professional baseball players get hurt pitching when I can throw pitch after pitch without getting sore?
The answer is, "Because you are doing it at 1/20th of the effort and skill level that they are, which means your body is being stressed significantly less and in different ways."
If you want to harbor delusions of grandeur and pretend that you or the average Z06 driver have a similar skill level to Pobst, be my guest. But don't expect anyone to take your arguments seriously.
