All of the performance things on the turbo engines like the oil squirters and oil cooled pistons are there to help increase their life over hundreds of thousands of miles of driving WOT on the autobahn, whereas I probably won't be taking the car over 70, maybe 75 max, for short periods (such as passing and merging on the freeway), and I'll be monitoring exhaust temperatures to make sure they don't exceed 1000-1100*F max (I seriously doubt I could get it up to 1100 though, and if I did I wouldn't let it stay there for more than a few seconds)
