I am going to use one for heat control. Heat shields are ugly. Blankies work.

To avoid my turbine housing from crumbling to dust (yeah ******* right), I ceramic coated it. I am going to wrap my ceramic turbo mani too. Oh nooooes!

 

+1. I plan on doing the same. May do an insulated shield for the turbo but i'm wrapping and coating everything else.

 

there is a mx-3 user on mx-3.com that is putting a descent amount of HP from a kl serie and use one of those blanket to prevent the coils to melt away.
he swear by those product


i had my turbo sitting 1/2'' away of my radiator in my mx and never had any problem(had awr solid mount)
so i dont really see why you would need one that bad tho

 

For another data point: A friend of mine had a blanket on his SC61-powered Miata and after 10-15k miles the blanket was completely deteriorated.

 

I have one on mine. I'm not sure if it makes a difference performance wise. If it does it's not noticeable on my car. It does keep the temps down pretty well because my master cylinder stopped melting.

As far as corrosion, it doesn't seem to make a difference as far as I can tell. Slightly rusty turbine housing is still slightly rusty.

Bryce is right as far as longevity. Mine did seem to wear out pretty fast. If I could find out for sure if a better quality one would last longer, I will probably get another. Mine still does the job though.

Fae's probably right about the coating and a blanket. I think I'll be heading in this direction. Coating to prevent corrosion and keep some of the heat in the turbine and a blanket to keep the under hood temps down as much as possible and keep the heat localized to the turbine area.

I would think if a lot of the OEM automotive and equipment manufacturers do it, there must be some reasoning behind it.

 

My two blankets have disintegrated too. On one the stitching died. The other, i moved it and put a hole in it with my finger :(

1400* cruise EGTs prob have something to do with it.

 

I think mine died prematurely because I was too lazy to tie it on tight once and the bottom folded over towards the turbine. It seems if anything on the outside of it touches the turbine it instantly falls apart. The top, actually is in really good shape.

I'm sure the leaky compressor seal I used to have didn't help either. It got soaked with a little oil on the inside. That couldn't have been good for it. It still works though.

 

I thought that you were supposed to soak the whole blanket in oil before you put it on; that way it would catch on fire?

 

I know the owner of that car personally, and prior to selling the car there were no issues with the turbo, its been on there almost 3 years now.

EDIT: beyond this statement im not saying im an expert in any fashion but I figured id add the info on this particular car's turbo lifespan

 

Damn it!!! I knew I was doing it wrong.

 

Perrin recently released a heat shield for Subarus. My engine bay was baking hot to the point where my legs would get crispy through the firewall. The entire engine would heat soak. The fitment with the Perrin (got it at cost, might as well try it) on my GT2560R is not perfect but it definitely does the job. Underhood temps are way down and my leg hairs no longer burn off.

 

I can claim to own one (DEI) - but got sick of removing/tearing it up to tighten loosening studs and bolts... so it sits in a box in the spare parts bin. Maybe I'll put it back on now that I have an ARTech log and TSE inconel stud kit... hopefully my **** won't loosen up!

 

This looks like a solid product, but it ******* costs over $200

 

I guess that confirms my theory on the oil.

 

I have that shield and wouldn't recommend it. It got brittle and is falling apart. Sigh

 

I guess i'll stick with my home made aluminum heat shield

 

I had one on my WRX. I got it mostly so that the top mount intercooler wouldn't heat soak as badly between auto-x runs. It did work very well, but my EGT's didn't break 1400 unless I beat on it for a while. Perhaps if they were higher, I would have had issues.

 

I had a blanket on my SC300 and it really helped with the underhood temps but the main reason I put one on is because the T78 sat on a top mount manifold and I did not want my paint job ruined.

 

People should post their brand and how well it holds up.

 

I have the DEI blanket. I could not notice a better spool up or performance, but the underhood temperatures are much lower. Now i can work better on a warm engine without burnt finger. :-)



Here is a blanket with cheaper material. It still works good on miata from a friend.
