DIY Heatshields In Progress

Swain Tech White-Lighting ftw
White Lightning Exhaust by Swain Tech for Automotive Coatings including engine piston coatings, ceramic coating services engine, automotive ceramic coating, ceramic header coating, dry film lubricant, race engine coatings, exhaust header coating
The only "ceramic" coating that will have a measureable effect. I plan on one day getting my turbine housing, manifold and downpipe all coated by Swain Tech.

Hustler gave me a good idea. I'm putting one of my mt.net stickers on my box when it's finished.
Getting back ON TOPIC...
Should I build two layers of steel over the turbine? The OEM part is two layers of steel, but they're pretty much touching each other. I could build the part that goes around the turbine say 1/4" clearance around the turbo, then a second layer riveted over it with a 1/8" air gap or something like that. Would an air gap make much difference between the two shields? I would think so.

Looking at various people's setups the question arose in my mind, does the length of tubing pre-turbo to the filter matter at all? SamS's for example is very long whereas some have but a few inches..

I'm gonna say the length doesn't matter much. I'm not even sure that the temperature matters. Again, I'm just doing all this to keep it cool so I can fill this box with foam to make it quieter.

Two layers is always going to be better for insulating because air is the insulator.
You stop the radiant heat with the shield, and the convective heat with the air gap. Double win. Most people don't spend the time/money/effort to do a second layer, but it will help.

Yeah, air gap FTW. I need to learn more about heat transfer. Like how shields reflect heat and all is news to me. Never saw it that way. Taking Thermo II now and heat transfer next semester though.
lol at your sig....

Mine is a single-layer steel construction, with the whole inner surface (top, side, rear) lined in Thermo Tec aluminized fiberglass blanket (this is why there are so many rivets; some of them are holding trim strips that retain the blanket). After a long drive, the outer surface of the shield, while warm, is cool enough to lay your hand on. If you really want to keep the heat in, but can't quite manage fully dual-layer construction, just line the inside with this stuff.

That's a very nice looking cover, Stein. I really wish I could have figured out a way to mount mine to the body rather than the engine, as it would have saved a lot of frustration with the early versions failing due to vibration. It took several tries to come up with a design that wouldn't crack in short order. With the placement of the turbo on the Greddy manifold however, there was nothing for it.
