A FMIC will also contribute to the radiator needing improved capacity, as well as significant power increase, which you're not really at yet. Also the type of events and how you drive. Road coarse will give you far better ambient airflow than and be far less abusive than brake-boosting through and auto-X event (no airflow and continuous high load). So many factors to consider. And if all else fails, we sell the hammer (radiator) when no other tool will work. Another tip for improving radiator performance (regardless of what you use) is to improve ambient airflow. A splitter, radiator shroud, belly pan (although the OEM one is really good), and even closing up gaps around the radiator will all contribute to improved cooling performance.

Auto-x is not a focus and no intent on being competitive. I use it a few times a year for training and keeping my reflexes good. I have fun with it but no interest on being competitive. Mostly HPDE and track days working toward time attack style events. I do spend time in UT and may do some track days there but it would be in May, September and October.

I will be making a custom belly pan and splitter in the spring. Already have a radiator shroud. I use a TMIC so no FMIC blocking flow. I'm using OEM fans and will be keeping them.

I was more thinking how you stated this pump housing is designed for higher rpm. Where do you find the OEM housing starts to suffer from turbulence?
