Nahh, I wouldn’t worry about it until you start seeing coolant temps >240F on track. The ECU won’t pull power until 242F.
And if you end up going BM3 or MHD, they have Max Cool modes that will set the engine temp setpoints lower so the engine is cooler when you start a track session. That will buy you a little more time before hitting higher temps.
Lastly, using a thicker 5W-40 oil for the track in the summer will bring oil temps down 10-15F, as well.
Those are some little things you can do before upgrading the radiator, but if you log and see coolant hit 242F it’s time to upgrade!
