The three ways to mitigate are air/air, air/water intercoolers or water/methanol injection.
I am playing now with water and water/meth injection but it uses a lot of fluid and is fairly active. I control it with the ECU so that above 124F it sprays until the air inlet temp reads below 124F. I picked that number as kind of a compromise so nothing sacred about it. I still end up using quite a bit of water so it is not practical for long trips.
The next experiment will be an air/water intercooler as I have no room in the engine bay for a reasonable air/air. The problem now is where to stick the radiator since most available fender space is used to have a working AC for Florida temps.

Best is that vancouver doesn't get overly hot.. but I understand what you mean
This kit was the non intercooler kit.. so we should definitely try to incorporate some type of water injection to keep things cool..
Last thing we need is a motor melting after a full rebuild
I do appreciate the education though.. I didn't think about temps
