I think mine is running around 90c (just when the fans come on) on the motorway, if driven hard that can rise...
Around 88deg mate, average running temps probably 85-95deg.

TBH though, the cooling systems ability to cool should be at its peak on the motorway, how much does your car over heat Roger? Could it be the thermostat closing because the coolant temp has dropped? maybe a slightly sticky stat....?
Rob,
You are right of course Rob, but IME the cooling systems ability to keep the engine at the correct temp is more than enough and if your getting hot you have another problem.. Lean, retarded, poorly seated head, blocked radiator, pipes, waterways, etc...
I ran 26psi on my .36/50 causing very high temps (and the turbine wheel to melt the tips and break off blades) and yet still never seen over 110deg.
