Default Turbo Blanket!?!?

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

If so, measureable difference in under hood temps?

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.

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?

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

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.

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.
