Stock Radiator sufficient for track day with 2L stock engine?


Any one know for track days if a good Stock Radiator (Performance Radiator) would be sufficient for a B20B that is run on a stock ECU?
Not buying a radiator from Orielys, it was way to easy to put a hole in it when installing the A/C condenser fan.

I did test the car for a cylinder headgasket leak and nothing showed up, radiator fans are working but inside the radiator I see all this white buildup that even prestone radiator flush don't remove. So I think its time for a new Radiator.
