Well since i got zero responses from the 2nd gen forum ill ask here.

How many of you guys use turbo insulation?

I ordered this DEI stuff that comes as a kit that has a rap for the exaust side of the turbo that ties with a metal string. I just wanted to get some feedbak on this stuff to see if it actually works and if it infact can lower the temprature under the hood significantly.
Thanks.

 

If this is what you're talking about...



...it works great. After a hard run you can actually touch the blanket (for just a moment) but it keeps temps down like you wouldn't believe. I ran for about a week without any kind of shield and then picked up one of these. It's totally night and day.

 

What kinda night and day differences? explain it to me like i'm a 5 year old

 

While I never measured specific temps I will have to say that the area surrounding the turbine housing is significantly cooler. Before the blanket went on I could watch heat just radiate through the hood and was really concerned with the long term heat exposure to the wiring harness, hood and surrounding wires/vacuum lines. I really should have had some sort of heat shield on it.

Anyway, with the blanket on the entire area is cooler. After boosting down the road I've pulled over and the UIM is not even warm. You can quickly brush your hand against the blanket and feel that it's hot underneath but not burn yourself. The area around the turbo where before you could feel heat radiating like a camp fire is now sequestered. Worth every penny to me.

 

you can touch the the cover? wow..

 

well worth it to pick one up.. i have one keeps things much cooler and keeps some non needed heat off the manafolds and stuff

 

Ordred the DEI kit yesterday as a matter of fact.
Should be here tomorrow.

 

Just as a follow up, because two of you mentioned the DEI kit I did some looking.. what I described from above was definitely not DEI. The DEI product seems to be more of a universal fitting deal where you sort of wrap it around and tie it up. The product sold by Gotham (pictured above) is fitted to wrap around a T4 style exhaust housing. I chose this over other less expensive products because it fit well.

I can't speak to the effectiveness of the DEI product. It does look similar to whatever JC Whitney sells though.

 

Yeah the DEI kit is nothing like that. Its like a thick foil rap that raps completly around the exuast side of the turbo. I mean just looking at the 2 it seems that the DEI is better because it covers up more area. How much did that cost?

 

How much is the Gotham Blanket?

 

I don't know.. that may sound logical but when space is tight you may not have the ability to wrap it like you think. The blanket from Gotham fit perfectly and despite being 3/8"-1/2" thick was decent to get it on the turbo. I'd be interested to see how these DEI blankets go in.

Oh, and the blanket from Gotham (and everywhere else that sells the same product) is around $120.

The DEI kit sucks. It is a bitch to put on, doesn't hold up well, and if you ever remove it you will have hell trying to reinstall it. Return it and buy the gotham kit.

 

i have the one from gotham in silver, the other dude is right, you can touch it after you drive the car, it's pretty cool...

 

could holding the heat in cause damage to the turbo since it can't cool as well?

 

Can someone show me a picture with that gotham blanket rapped around a turbo?
But did it in fact keep the underhood temperature down?
It sounds like if you get it installed right it might in fact be a good product.

 

 

Here's a few pics. It looks like silicone-covered denim jeans..

As to additional wear on the turbo, I haven't seen any evidence that it's significant enough to worry about. Besides, I'd gladly trade a turbo housing 3-4 years for cooler temps and potentially faster spooling.

I wonder if this would fit under my polished heat shield (would keep it mainly for looks) Its a pretty tight fit as it is now.

 

i have a t3 exhaust housing and it fits nice and snug on it too.

 

*UPDATE*

I got the DEI kit and after looking it over it really seems like it'll get the job done just fine. The only problem is that it looks like in order for me to get it on fit and snug im going to have to remove the turbo.
Theres basically 2 types of insulation in the package. There a fiber material that is responsible for the actual insulation then theres the aluminum type material that goes over it. Then to hold it on there these stainless steal zip tie things to hold everything on.
Then lastly theres a rap for the DP.
I dont know i mean looking at that gotham kit it looks like itll be 100 times easier to put on but its double the price...So i gotto think about it a little i think.
Thanks for all the info Ill keep you posted.

 

NewbernD, did you have to remove your turbo to get that unit on right??

 

NewbernD-.. what size turbo do you have? Gothams site says it works up to a T66 turbonetics andT88 Greddy. I have the T 70 Turbonetics and can't seem to find one to fit. What are your thoughts as to how close it would be for me?

 

If any of you do a search you will find that this has been discussed before by a few VERY knowledgeable and experienced rotor heads (Crisspeed , Rice racing , turbostreetfighter and others ) , generally what was said is that blanketing IS BAD for your turbo , too much heat is retained in the turbo and it causes premature failure of the oil seals and bearings . Yes there is a significant reduction in underhood temps . but where do you think the heat is now going ?, we all know how hellishly hot our exhausts runs compared to other types of motors but whats good for a piston isn't good for us, what ever you think you have gained from blanketing your turbo , you will soon loose when your turbo overheats and fails prematurely.
If anything you can use heat shielding to block the heat from going where you don't want it , you should not insullate your exhaust manifold either !!.
