Cool stuff. Nice installation, but..........
With a radiator, airflow is everything. Blocking the airflow exiting it directly to the firewall is NOT a good solution.......and as you say, the air is warmed up going over the engine as well. Good ducting to from the radiator and oil coolers is paramount.
Has it flown yet?

I visited a guy in Colorado with one of the Powersport packages, and it was fun to see it in person after reading about it over the years.  His only cooling issue is the water side, and some of that maybe having the radiator mounted to the firewall, where the cooling air has to flow around the hot engine, prior reaching the rad.?  He fired it up it, and their peripheral port had a crazy “snarl”, compared to my Renesis or 13B!  Fun stuff…
