track temperature issues

[Jon8710]

Hello chaps

I did an evening track day the other week at snetterton and noticed that the temperature gauges where getting to levels iv not seen in the CSL before.

after about 10min of spirited driving I notice the water getting to over three quarters and the oil getting to about 130ish if not a little over.

if I eased of the water would drop quite quickly to half way and the oil drop a little but the water would shoot up again after a hot half lap.

it was a warm day around 26 degrees but I have done loads of track days in my 328i track car and the water never budges.

im sure this is not normal can any one offer any advise?

I had the head done a few years back by Gareth at elms so hoping this is not an issue.

cheers
