You have to remember this is a general sense. Not all radiators and engines are designed equal. This makes some sense, but general heat rises up exponentially due to engine bay design (increase 100% in power = 200% heat rise, use intercooler). On the new Celicas, even if you double the HP, you do not need an intercooler because of large mouth gap plus angled radiator setup. On the Z, the stock radiator is very beefy, but still not enough to cool the oil :shrug:
