I think your last point is key here. The cooling system was designed for a little over half the horsepower we can make now easily. There has to be a wholistic approach. If you want to make “modern” power you need “modern” cooling to be able to utilize it. That means modifying the cooling system. I don’t know that anyone has done a comprehensive evaluation of the stock setup with the power levels we routinely run now. People have tried this or that but I have not seen a thorough study.
None of these problems are new though. Ask the Ecoboost guys running a tune how hard it is to keep those cool. The extra heat from the turbos does make a difference.
