I did a little searching and I'm sure not many people are interested in some tech about something so simple. Either way I'm looking for a little advice for some heat shields. My XJ's drivetrain-AW4, D300- puts off an incredible amount of heat, as does the exhaust which runs along side the drivetrain, next to the P/S tranny tunnel. That makes a black XJ miserable. . .
I'm in the process of building all new sheet metal for the tranny tunnel to hide all the links and mount the seats in with the rollcage and wanted to build some sort of heat barrier to keep the interior temps down.
I was thinking of doing 2 things or a combination of the two.
1) Making each sheet of the floor/tranny tunnel double walled-spaced about 1/4-1/2" apart.
2) Making small heat shields spaced off the floor/tranny tunnel located along the exhaust and some of the drivetrain. Instead of the heat shield just being flat like the interior piece it'll attatch to, these will curve to follow whatever it's shielding the heat from.
Here are my questions:
1) How far should the heat shields be spaced from the interior sheet metal to get the most heat reduction out of them?
2) Which option sounds best to eliminate as much heat as possible without creating a bunch of unnecessary work?
I don't mind the extra work, I just don't want to spend the time making everything double walled for little return.
