Me and my mate Dan (Mau5_Skills/Dantastic) have just been running it. I haven't really managed to get a clean lap down together yet, but he has the following splits:
T1 - (27.468)
T2 - (17.296)
I have seen a .4 first split and .2 second split also, but haven't put them together yet!
Edit: He has just hit a .286 1st split, really? :/
His tips: Brake at the 50m marker for 1st bend, dive in early for 2nd and 3rd bends, start out wide for left hander, shift up to 4th before left-right section and then he's not sure how to do the last bend.
