BMW now is going to extract the most power they ever had out of that poor 3.0l I6. It is a risky recipe. I wish they had a better idea than an S55.
M3 drivers are not M5 drivers, its a totally diff crowd.
Again, I hope BMW's engineers read your thorough analysis of the differences in heating/cooling issues regarding turbo charged engines versus NA. This is probably news to them.
