With my home country in tropical area , at winter
The weather will still rock to 30c , some kind of hood vent is a must for track day .pick this FRP hood from Vendor at Japan, that already come with some type of vent
Although is kinda da mainly for look specifically front section, but on rear section of vent . I can still see some hot air get vent out , and my datalogger prove it almost 10 degree different In stock and go traffic

I will build a hood rouver at next stage , this should really help cooling and IAT at track day

Interesting. Could experiment with removing the rubber from the rear edge of the engine bay opening and spacing up the rear of the bonnet slightly.

That area is high persons zone from air flow so
It might make it worse at hight speed, it might help little at idle and stop and go traffic
