brody, wrapping a SS manifold is a HORRIBLE idea for the longevity of the manifold.
and donnie...... i don't want anything asbestos near me LOL
wuss
my buddy had a torch setup for glass blowing... the stuff is only dangerous if you breathe in dust (from cutting for example) or something like that. Its safe to handle as a cloth.
You could just use something like the header wrap material in between... basically just have a filler for air gap as a buffer... kind of like a radiant barrier in an attic
Aluminum will have to be thicker than the SS to resist the same amount of heat compared to the SS. Space is at a premium next to his radiator which is why I thought the SS was the better choice... I guess it depends on which aluminum you use and its resistance to heat.
I'm with D323 on the thicker aluminium, but like he says, there are different grades of aliminium!
On the rotary we use a aluminium heatshield, will just confirm the thickness later. Its not a turbo rotary, but they generate very high temps at the exhaust. That shield works really well, that's some times even after hard driving, there are little water drops on the outside of the intake!
yeah I would go with polished stainless.....at least it will stay shiny whereas aluminum may not.
At the end of the day it needs to reflect the radiant heat, making it dual layer with some sort of insulator in between is great for OEMs but they have the resources to make sandwich materials...but dont forget none of their stuff is polished.
OEM covers I seen consist of two outer shields with a spacer like a steel mesh in between.
And yeah I am big fan of heat wrap, but I wouldnt use it on a tubular manifold.
