In the city mine rides at 240 - easy sometimes a bit hotter, perhaps 250. On the track - these engines hit 300 easy. 2 turbos - heat comes with the territory. Its normal however I doubt the longevity of these engines compared to BMW's non turbo model. I guess 200k max (IMHO)
I suggest more frequent oil changes since heat kills oil. I change mine between 5-7.5k.
