Sorry to bring an old thread up. But I was just too excited that I had to share.

I did it, I finally did a 2:08 lap in my mostly stock E92 335i. The cooler ambient temp really helped as I didn't feel power loss at all, and I was able to put more laps continuously. Anyway, here's the video of my 2:08.55 lap from this past Friday.
