so next to the thicknesses I've been in four ringer with hair dryer in the last 2 years
or even double-feder 
in love.Also because my S4 Avant only finished about 2 months ago due to turbo damage (that was a procedure).
With the Biturbo, the large trouser tubes with metal cats were installed, and the car has a 76 mm, practically open exhaust system (with mountable ESD - who has already seen racing cars, know how the looks) made of stainless steel. The sound is of course what it should be like (although you can already hear the turbos in the exhaust, as with some WRCs
) The system has been wound, so there the resulting heat amounts have been somehow regulated.One problem is the heat generated at the top of the large Alu-Y pipe (intake tube). I don't want to wrap the piece because then it looks pretty disgusting, even though I don't see cars with aesthetics and discolight
A neighbor has recommended me a material, namely this AeroGel, practically looks like a thin sponge, but can absorb enormous amount of heat. What do you think it would help if at least a layer of this kind were inserted under the intake tube? This could reduce the temperature of the air in which it is sucked.
The same, but of course more intense warm-up was observed in the Rally-Uri (A2) 2.2-10V of a friend.
There is the big Garrett GT30 just under the intake manifold, and when it glows, everything gets really hot. I have an idea there: to put layers of aluminium foil - aerogel - winding material on each other, so that no water or moisture reaches this AeroGel (it is said that the material does not like the moisture).
If anyone had such experience with "insulation"...
Thank you in advance!
