Worlds Best Heat Shield - Rat Wheel Spinning
 

So who would pay 60 bucks for the worlds best heat shield?

Basically I am thinking of using aerogel as an insulator between the two sheets of metal.

Ideas?

Gold too .....?

Between two sheets of Stainless Steel? What's aerogel?

Its 45 dollars for a liter of granular aerogel. I don't need solid blocks of it.

I sall that stuff on a show about space, they use it on probes that collect comet dust. Its cool stuff, like 99% air lol. I wanna hold some.

Looks so hot, I want one!

gold foil + aerogel sandwich would be about as effective as you can get. realistically you can just use polished aluminum. no need for stainless steel--its lower thermal conductivity doesn't matter since its not conducting much.

Is this the stuff that floats when charged with static electricity?

How would this compare to the $100 turbine housing insulating blankets?

Sounds cool.
What about a Nomex blanket with an aerogel liner?

Aerogel can have a 1000° delta on opposite sides.

While it would be super rediculously effective. like...about as effective as i can possibly imagine. What about moisture? I know it can play a pivotal role in the deterioration of aerogel. I don't think layers of metal will keep it out =\

That would be sooo hot btw. and by hot, I mean cool. if it wasn't for the fact that there's radiant heat in the engine bat and the proximity to the exhaust in general you could put your hand on that heat sheild while the turbo was running full blast.

Actually, I have a manifold heat shield as well *hmmmm*. what I really would need though is some way to effectively evacuate hot air. Oh god, I have so many fucking good ideas and no money to play with and experiment. Wish I did, because then I'd have a reason to ask for my magnehelic gauge back from scott.

you dont need the nomex if you have aerogel, right?

what about coating the manifold in aerogel and then gold leaf.

hello Mr. $1500 manifold....

i have an aerogel brick somewhere from a trade show. lol

The nomex blanket is basically just the vessel. Plus it would be flexible to fit around any turbo.

Cut costs... make your own Aerogel...

i need to coat the floor of the car with that shit

this just reminds me that i need a heatshield.

awesome idea...keep this thread updated. My thin sheet metal in between gives me the heeby geebies

Commercial manufacture of aerogel 'blankets' began around the year 2000. An aerogel blanket is a composite of silica aerogel and fibrous reinforcement that turns the brittle aerogel into a durable, flexible material. The mechanical and thermal properties of the product may be varied based upon the choice of reinforcing fibers, the aerogel matrix, and opacification additives included in the composite.
