Great post chock filled with what I have seen. Though I’d slightly disagree on the fuel to a point. “Super Cooling” the fuel is not a good idea. Running cooler fuel is helpful. Running a cool can helps there. Just regular ice in the can.
Cooler air is the main key. Ether via a sealed air entry to the hood and its scoop or a do it yourself CAI like what they have for modern cars.
When the summer heat is on, even the air at the track is a good temp drop from the air inside the engine compartment. Cooler fuel will help. It’s just a little bit, but it helps.
