One of the biggest contibutors of the heat is how your car is constructed. The Shelby for example has a lot of pieces and parts riveted and fit together between you and the "heat pump" up front. If there are small gaps the under hood air pressure builds up. That's why the cars have side louvres and riveted front hood skins. If there are any holes, especially ones like a poorly fit outside footbox edge, the heat pumps in. A Contemporary on the other hand has a fibreglass cockpit moulded right in to the body. If you have good grommets and seals for any small holes for gauges and wiring there is almost no hot air transferring in. Indeed the best solution is to keep it out in the first place. On the outside of the footbox use a heat barrier/insulator and put a polished stainless or aluminum reflective barrier over the top of that and it both reflects and insulates. There are three heat transfer methods right, conduction, convection and radiation. I still stand by the footbox vents as making a very noticeable difference in whether your shoes are getting melted to the pedals or you can still keep driving in reasonable comfort for a loud, hot, uncomfortable, obnoxious car we love so much.
