If I look at the circuit map
http://www.snetterton.co.uk/media/65500 ... p_both.pdf I will say that at RPM the "U" beginning my red line you are driving "Williams corner" at that moment. Your cursor shows the end of the "Bentley Straight".
Is this correct?

In my red arrow the ECT raises up at the Bentley Straight where you have full throttle.
This shows me that your water cooling is not very effizient because the air pressure to the rad is here at the maximum.
You see at this section the AIRT is falling.
At Brundle and Nelson corner the ECT is falling but the AIRT is raising very rapidly. His very rapid increase surprises me.
Possibly the aftercooler eats the hot air of the water cooler. Try to install a horizontal cover at the front behind the rad so that the hot air does not come under the car, but is only discharged to the side.
I agree with [mention]Monza[/mention] that the coolant temperature problem must be solved first.
Because I think that's why the ECU is cutting the power to protect the components.
The efficiency of the intercooler is also not great, because at an ambient temperature of 20° it just cools down to 40-45°C.
Now make my suggestion above and then show the log again.
