You don't have to get it from A.S.S. or settle for the two sizes they offer, it can be had from an industrial insulation supplier like E J Bartells. As for recommendations for insulation for your turbo, Find the local for the Insulators Union (International Association and Brotherhood of Heat and Frost Insulators) and track down a couple of the members.

Hi, Russell.....here's an interesting web site regarding heat shield material.  www.tamfg.com/new/fb/fb.html   I have some fibrefrax here. I used it between my firewall and the aluminum firewall covering. I will also use it between the brake disc and the nylaflow brake line tubing.  Works very well as a heat shield, for what it's worth.   The Renesis engine will probably sell for higher than it is now.....I had considered 4500.00 as the most I wanted to pay.  Hope this helps.

Subject: [FlyRotary] Fiberfrax?

Regarding my need for turbo insulation, a quick look through my Spruce catalog came up with this cool stuff, and now that I see it, I believe Tommy told me about this before.  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
 
13 minutes left on the Renesis engine auction.  It's at $5000 now, and I'm guessing it will go at $6200. 
 
Rusty, Fiberfrax is an industrial material used for insulating boilers and other high temp areas. You know this, I'm sure. You don't have to get it from A.S.S. or settle for the two sizes they offer, it can be had from an industrial insulation supplier like E J Bartells. As for recommendations for insulation for your turbo, Find the local for the Insulators Union (International Association and Brotherhood of  Heat and Frost Insulators) and track down a couple of the members. Ask them for a material, they put it on and take it off every day, and they know what holds up and what doesn't. As for Fiberfrax, it's a replacement for Asbestos and should be handled and, where used, encapsulated just like you would asbestos.
