turbo heat shield

[Tooltime]

I ordered some parts from Jegs and when my parts arrived they sent along a catalog. When I was browsing the catalog I spotted a turbo heat shield blanket type thingy and it got me thinking. Since the intercooler is above the turbo maybe give the turbo blanket a try and wrap the intercooler in some thermo heat shield. That might help cool the charge of air. My question is, has anyone tried this yet?

I liked it.

I used some fire blanket for high temp @3000 and it did a great job. As long as it stays clean, oil free it keeps the heat in the turbo. The ic in the stock location will love you for it.
Some turbos car come with heat sheilds that defect heat.
I am still looking to build one to keep the heat off the plugs and wires that are close to it. One day that is.

how good an idea is it to keep the heat in the turbo ??

Dont.......

wrap that turbo......keep some kind of a gap...you really need something rigid that will keep its shape...

Better than keeping it in the ic.
The life of some turbos I would think is because they were not balanced well or the oil was not changed enough.
Lost of heat in the turbo is lost of power.
I drove the 88tc like a dog most of its life and even when I sold it at 128000 it still had no problem with the turbo.
Did not know about letting it run for a while after beating on it.
Most of us change the oil like clockwork.
I like the sheild better cause it will cool down after the runs are done.
As you can see I don't use it anymore and have gone to the sheild idea.

He's right about the gap. water will get in there and cause rust.

On the heat soak and the oil left in the turbo bearing.

That would be a good question for someone else.

They can't live forever.

The more heat that you can keep in the exhaust flow of the turbine housing, the better.

Don't forget that in effect you have a gas turbine engine bolted to the exhaust system of the car. Heat creates exhaust gas expansion and a rise in pressure at the restriction. In a gas turbine, you want the temp and pressure to max out where they meet the turbine blades. Keeping the heat inside the turbine housing passage is the goal, whether it be by the means of ceramic coatings (inside as well as outside) or a Kevlar diaper on the exterior.

I consider an air gap between the turbine housing and the blanket cover as only a distraction to the goal, since we are dealing with cast iron (Meehanite, Stainless, whatever is being used), which will far outlast the rest of the exhaust system when we begin to talk about rust and corrosion.

I had several beers before writing that last one, and it's 2:30AM.

I hope that I appear as smart in the morning to everyone else as I do to myself right now!

Mr. Leslie had something similiar on his car before he went to a FMIC set-up. I talked to him about this at the reunion and being the good guy that he is, he still have to original heat shield he fabricated for use between the stock IC and turbo. I traced this out on cardboard when I saw the piece. I need to get off my butt and have something fabbed up. I'll try and get to this in the Spring and post my results. Not much help right now, but maybe in the future.

An '86 Cougar I bought had a heat shield on it. I dunno if it was a factory thing or someone made it. It was just nice enough I thought it might be factory - just rough enough I couldn't use it. You'll have to forgive me, but I tossed it.

I guess that they never removed a turbine housing bolt before.
