Turbo Blanket!?!?
 

Anybody here using them? Happy with the product, pictures?

If so, measureable difference in under hood temps?

Attachment 198205

Using something different to combat under hood temps, please elaborate/show pictures I need some heatshielding ideas.

They suck. You can and will get the turbo too hot. Put a brake duct hose pointed at the turbo instead.

Hustler is wrong. Turbo's on Miata's generally run in the "danger zone", or 40-140*F. To prevent them from growing dangerous bacteria, we keep them warmer with turbo blankets.

I just give mine a z-pak

...

As someone that sells turbos, I fully support the use of a product that promotes corrosion and has no measurable performance benefits. Anything that means you'll be replacing a $300 turbine housing every 2-3 years is a good buy in my book.

(don't waste your money.)

Granted my car is a street car, but I've had one on for a long time and still have my exhaust housing. I should check it and get some photos.

Does ni-resist make a difference? (The GT2876 .64 housing is, right?)

Have any of you all tried Jet-hot or similar coatings to help keep some of the heat in? I don't know if it will bring temps down enough with how close the brake system sits to the turbine housing, but worth a try maybe?

Pictures y8s?

Thanks for the insight from sav and you too y8s...

Haven't you been on miata.net? The best way to get lower underhood temps is a cold side supercharger and e cool.

Best post ever. Those guys are pretty stubborn :jerkit:

Hahaha its in the mail already.

I do got one, engine runs good and I do not see any signs of rust or premature deterioration. Dont have any numbers but could tell engine bay much cooler than before.
On my setup as my car is FWD, the turbo is very close to the radiator and that is the number one reason to get the blanket.


(Like I have stated, I got a FWD 323/Protege, but with a BP engine thats why I come and go to this website). Plus a friend has a Miata and everynow and then contemplate buying one. Almost did the other day, but was to late already sold in Orlando.

Well, not to walk on anyone's miata experience here, but I do have experience with one on the grand prix. They came factory on the STE's, when i got mine it had the factory turbo. No noticeable premature wear after 15 years.

I am interested in a blanket. Any reports of issues with turbo blankets?

ive herd the same BS about blankets causing corrosion as exhaust wrap causes corrosion. but for bad corrosion you usually need moisture. how would moisture stay on the exhaust when is well above 212*F. ive had my home made mild steel turbo manifold wrapped for almost a year now with no rust on it. i un wrapped and re wrapped it a few weeks ago cause one of my hose clamps broke and it unraveled on one one runner.

the only thing keeping me from getting a turbo blanket is price.

:facepalm:

Read the responses above, they list a few experiences with them.

I'll say it again: for a street car, I think they're fine. unless you want to argue with the 50,000 miles and 7 years I've run one on my car.

I've heard good things lately about turbo blankets and downpipe wraps from a few reliable sources so I'm going to give the latter a try in interest of aiding spool/efficiency

They are oem on lots of diesels I sell and only seem to have corrosion issues on ones that sit without running much of the time. Diesels run lower EGTs so it might let them make better power or efficiency. IDK much.

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 fucking 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.:giggle:

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. :vash:

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 shit won't loosen up!

This looks like a solid product, but it fucking 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.

Thats a funny place for the filter, why not run it behind the headlight?

It was the easiest way and i think its cooler as near the turbocharger without a blanket. Not perfect but works nearly 10years now. With MAF in place i spend no more time to the filter location.

This blanket material looks like mine
