We need to get into heat shielding in a big way in the race cars with so much
additional heat floating around.
The best shield would be some refractory material like asbestos or one of the
safer modern substitutes.
Just having a sheet of metal is also quite effective to block radiation of
heat energy - I use a sheet of aluminum on some stand-offs with no other
material to shield a trunk bulkhead from the turbocharger unit in my Fiero -
without the sheet of alloy, the heat burned/oxidised through the trunk metal
and melted some insulation on some wires 12 cm away. With the sheet, no
problems.
