As many of you may know I designed and I build the turbocharger heat shields for Flyin' Miata. I also make heat shields for GReddy turbos which FM markets for me. So far I've made over 600 of them.
The design of these heat shields takes advantage of the properties of polished stainless steel to reflect infrared radiation (radiant heat), and it utilizes the turbulent air flow in the engine bay to keep the heat shield cool. My initial testing of the FM heat shield on my own car indicated that the heat shield didn't get over about 300°F (even though it was quite close to the red hot turbocharger) except when the vehicle was stopped after a run, and then the temperature stayed below 400°F. The design is quite effective. The same type of heat shield would work well in any application where the heat source produced a lot of radiant heat, and there was a lot of air flow around the heat shield. Stainless steel would be a little better than aluminum, but the aluminum would probably be satisfactory. I wouldn't use two layers, because one should do the job.
