Supposedly, it's good for 2300 degrees continuous, and comes in 1/16" and 1/8" thicknesses.  I'd have to say the 1/8" thickness of this stuff is the leading candidate for turbo wrap.  There's also an aluminized heat shield material that is made my Thermo-tec, but since their exhaust wrap clearly doesn't stand up to 2000 degrees like they claim, I don't think I can believe any other Thermo-tec advertising. 

 

Any experience with this Fiberfrax stuff?

 

Thanks,

Rusty, I have attempted to use Fiberfax, and I guess its OK for some applications like bonding it to a flat surface (such as a firewall, bottom of fuselage).  However, I found that it did not confrom very well to other surfaces and tended to fragment into small sections.  Also, it is a magnet for any oil or other liquids (don't ask how I know).  I tried to use it to protect my cowl from my headers and finally decided that, oil soaked, it presented more of a fire hazard than anything else.  I ripped it out and used some heavy gauge aluminum foil which I layed over some thinned RTV that I painted on the cowl and its still going strong.
