From that same wiki article...
I am waiting for a quote/sample of the material.

1) Turbo blanket and some downpipe covering with material.
2) Home made blanket using granular aerogel
3) Heat shield with aerogel insulator

I hope the blanket stuff comes through.

An incredibly expensive way to kill someone.... Throw them in a vat of aerogel.

I suppose it would. It says it's a very powerful dessicant, and that just handling it will leave dry spots on your fingers. Might take awhile, but it'll get the job done.

I would wonder how much moisture it could take out. I guess if we could get someone to swim through a pool of it.

You can coat it to make it less absorptive, and you can even treat the entire gel by flushing stuff through it.

You could probably wrap your entire exhaust with granual impregnated duct tape.

I got a bunch of samples, should be here next week sometime. I guess when they make the blanket the mixture is actually hydrophobic, which is awesome for our application. They can also make exact blankets with given dimensions, I will set it up to fit a GT2860 with begi downpipe. Let you guys know how it goes.

I really worry about cooling. If you're adding heat inside an insulated box, it eventually hits any given temp you care to imagine. Maybe not tieing it shut on bottom, or building a small frame to space it out so that airflow can take the heat away out the bottom of the car - otherwise you're counting on the exhaust and conduction along the pipes to do it.

Well, we'll see. :-)

I think your looking at this the wrong way. THe heat is in the box, insulation does nothing but retard its transfer.

what about that big round hole at the back of your car where the heat gets out?

That's what I was saying - you're counting on the exhaust to take the heat out. I dunno, I guess it's not an issue, but it would seem the turbo would get even toastier.

At least the thermal stresses of rapid cooling should be removed. :-)
