I recently sold my 211 ( now I wish I hadn’t!)
I had done a number of performance mods including BOE Rev 400 SC with air to water charge cooling .
I can’t find the data logging with OEM temps but recall it was high after a few laps timing was pulled to protect engine , same issue as well document in the Elise / Exige .
Track driving and sustained rpm is the problem , I didn’t have an issue on the street .
Possibly the best and easiest proven solution is the Pro Alloy kit https://www.proalloy.co.uk/products/211-charge-cooler
If you want more info re temps let me know
