more complicated, yes...

more expensive, yes...

more accurate, prolly...

solve anything, or produce usefull info? usually not...:)

I forgot to mention I have a 1998 and after my long drive the trunk was NOT even warm, much less hot. Maybe this was a fluke but I think if it gets hot it would have the other day too. Anyway I'm happy with my results. Don't have to worry about melting toothbrushes on trips. lol.

Not only that, but the 987 rear trunk looks a lot bigger than the 986.

I 2nd the comment about keeping pizza warm. My rear trunk definitely heats up.

I would venture to say 5 minutes after you stop driving your trunk is the hottest. While it's parked, there is no air flow and what we call the "risidual heat" is just rising off the exhaust system radiating into the trunk.

FWIW - I had my leaking coolant bottle replaced and in the small amount of drive time since then my trunk smells a lot better and seems to be cooler (this could be in my head, but I don't think so). I think the relatively small amount of coolant that was leaking out under the carpet was hot enough to raise the temp.

If you're one of the posters who thinks your trunk is really hot, lift up the right side of the carpet and flooring to see if you have some coolant on the trunk floor :).

If your carpet got wet it would be a better heat conductor vs. insulator. The dampness probably didn't heat it up only allow it to absorb heat. Kind of like when your welding and have gloves on, and then you hold your hot part under water to cool it off only to splash water on your glove and then the heat transfers through the moisture and burns your hand. :(
