PTP Turbo Blanket
Hey guys, I've not yet seen this for he EFR turbo though I'm sure it's been out for a while. What's the general opinion on them? Worthwhile investment? I do need to build a heatshield, but the top mount turbo kind of warms everything around it, and melts many things too. I have a Garagestar brake master brace with the delrin end, which melted at the track.

General consensus on mt is that we do not care for turbo blankets. There are some older threads you can search for that have a ton more details. Building a real metal heat shield is the preferred method.

blankets are debatable.
heat shields are mandatory on track cars. |
Vlad owned a Subaru, so wanting a turbo blanket is still engrained in his blood.
Heat shield is very mandatory. I made mine out of license plates. It's not perfect but it works. @sixshooter and @patsmx5 have some good heat shield solutions. |
DIY tarbo blanket on the wrx, none on the miata. There used to be one on the miata, but it caused a wee fire.

I've installed em on lots of cars tho, and they do work, and have yet to personally see a failure as a result I do use heat shields on every single car tho. No matter what that part we all agree on |
So the heat shield to block off the brake booster and that corner of the bay is mandatory. Aside from that, should I attempt to build some kind of box over the entire turbo and down pipe area, just leaving the air filter exposed? I do have a louvre that ends right at the inlet to the turbo.

I run a turbo blanket, but I also don't track my car. At some point I may install a heat shield but I was fiddling so much with my turbo that I never bothered installing the one I had.

yes, ideally if you can box in the hotside and dp as much as possible

On the body. Too much vibration on engine. And never to both(sorry if too obvious). Look at the Flyin Miata website for their kit instructions, and you can get a feel.
|
My car doesn't have a heatshield. I tried to get one, but it doesn't fit the artech setup. I wrapped my downpipe, but the turbo is nice and toasty and convects through the hood vents a lot as though I where in a perpetual mirage.
|
Fabbed up a box made out of mirror-polished stainless (). It covers the turbo and DP and is bolted to the shelf and the prop valve mount. Seams are done over with heat-tape and there's a layer of "lava mat" on the side next to the MC.
Simple but effective. |

this is not really something you gotta go outside the box on (pun, teehee) as both FM and BEGi have been making really effective heat shields for years.

This material works extremley well, it has ceramic fivers sanwiched between two aluminum sheets, it was the best performing heat shield i tested when testing heat shields at 3m

Shielding is mandatory, but blankets keep too much heat in the housing for anything other than light street use.
Boost Lab rebuilds hundreds of turbos a week and Kirk has indicated that the hot side oil seal is always cooked and coked on units with blankets. He said often the hot side bearings showed damage due to excessive heat and coking in a way that non-blanketed units did not. A simple metal shield to stop radiant heat (think sunlight's direct rays versus being in the shade) will do the most to help protect components without overheating the turbo. The internal wastegate flapper shaft on my Chinese turbo distorted and seized on two different exhaust housings prior to my discovery that the extreme heat (G-L-O-W-I-N-G under the blanket even after a long cool down lap) was removing the tempering from the metal and making the straight shaft get squiggly. It may not have happened if it was a Borg or Garrett but it isn't worth subjecting them to it for longevity reasons. It was also extra hell on the studs but that's a different issue. |

I'll never use one again. :eggplant: |
Slightly off topic but what about ceramic coating on the turbine housing. Can that be bad for the bearings/seals too? I was planning on having Swaintech coat my EFR turbine but haven't yet.
