Do turbo blankets actually work? What is the purpose of a turbo blanket? What are the advantages of using a turbo blanket?
This video involves two tests, one completed by myself and Humble Mechanic, the other as a thesis for a masters at UT Austin. For our tests, we seek to see if there are any major temperature differences between using a turbo blanket, versus not. This can mean different cabin temperatures, lower hood temperatures, lower engine bay temperatures, and even lower intake air temperatures.
The idea of a turbo blanket is that it keeps all the exhaust heat contained within the turbocharger, rather than radiating out from it. This means more heat is contained as useful pressure, and that pressure spins the turbochargers. With more pressure, you create more power. Does it actually work? Let's watch and find out!

Please do this test with exhaust manifold (header) heat wrap. I always wondered if wrapping header(s) made a difference

@HumbleMechanic 6 лет назад

This header is not really built for a wrap. I think a wrap would just be super awkward on the header. It would however be great for a ceramic coat. But that introduces a lot of variables as the coating takes more time to do than the blanket.

@TheArchetypeGamer 6 лет назад

Why not take off the manifold and get it ceramic coated and retest after that part has been coated to see performance gains.

@rogerpearson9081 6 лет назад

Wrapping the whole exhaust is theoretically good but then you have to contend with the metal degrading quickly because of the super high temps There are exotic metals like they use in F1 ( Inconel...$$$$) but the cost vs gain is probably better spent in a bigger intercooler etc. A coating is probably better as it still restricts the heat and protects the surfaces but allows a bit more cooling

@rogerpearson9081 6 лет назад

Thanks guys, very informative from a practical view. Having seen a 350 C.I V8 ( 6.0 liter here in OZ) twin turbo fitted with blankets, I think it is a no brainer for the waste heat in the compartment alone. On popping the bonnet, I did not get face scorched and all the wiring and hoses etc would not be scorched and brittle. Then you have the performance/reliability benefits of not heating intakes, coolant and oil lines etc. To be thermodynamically pure, you should wrap or coat the whole exhaust system pre turbo but then you have metallurgical problems with the metal burning because of the high temps unless you go exotic. It looks like a blanket might even be useful on more humble cars like my TDi Sportage although I have no complaints about response but it would aid response and help the heat issue in summer ( 45 deg.C ambients) as long as there weren't bad effects on the DPF because of the extra heat passed along.

@PacificCoastAuto 6 лет назад

A lot of people are asking why OEMs don't put these on their cars. Some said cost, which seems reasonable at first, but falls off when thinking of the enormous costs that manufacturers spend on small increments in other areas. My best guess would be that a turbo blanket would require proper cooling systems for the turbo after the engine is off, and that these systems don't overcome the perceived benefits. What the turbo blanket would do is keep the heat in the turbo. This is fine while the car is running because the turbo is cooled by circulating oil. But when the engine is turned off, that oil sits in the turbo and and has no way to cool down. There is a device called a turbo timer that alleviates this problem, but it also means leaving the engine running for a short time after the car is shut off. With a turbo blanket, that 15 seconds might become 2-3 minutes. That is fine for the aftermarket, but would be weird for an OEM car that needs to meet regulations in several countries and meet delicate branding in order to be sold.

@@SupraSav Yes, I don't think temps are an issue with turbos (as far as blankets are concerned). I'd probably say it's most likely due to cost since that would almost certainly require a manual labor component to what is probably the usual automation aspect of manufacturing a car. Also, a service mechanic having to wrestle with it would be another cost consideration (although it would be a customer focused cost) for something that is essentially a performance luxury value added item versus the requirements for a stable operation component being added.

@rogerdalton1549 6 лет назад

Very cool, well done video. I'm curious, besides oil temp concerns possibly effecting wear, might there by any other downsides with respect to turbo wear, by keeping it hotter than designed from the factory? I understand turbos are intended to run hot by design, but I'm curious if raising the turbo temp (by 149.4 *C in this case) could wear anything out faster? I know the bearings are located around the middle of the impeller/compressor assembly, further away from the turbo top, but I'm guessing they would be getting hotter as well. Over time, the turbo will be experiencing greater temperature swings between cold/hot/cold cycles, and maybe that could accelerate fatigue of the turbo housing, compared to stock? Then again, the difference could be negligible. Thanks again for another great video, science be praised!

@MeltingRubberZ28 4 года назад

I guess portions of the turbo are hotter than they would have been, but as they mentioned in the video, the exhaust gases entering the turbo are the exact same. If anything this is making the turbo temperature more uniform throughout...which is elevated in some spots and roughly unchanged in other spots. It's interested to think about though, since certain portions of the turbo are seeing a heavier thermal cycling load.

@krinkedsurface 2 года назад

Yeah, I just think the same. They could have gone further and talked about heat transfer through contact of those parts you mentioned. It is said OEM housings wear out and and can crack for such temp increase...

How long does it take to cool off with the turbo blanket and without the turbo blanket and can the turbo melt with the turbo blanket because it keeps the heat in and if the heat stayes in same will happen with cold air it will stay out can you answer this please? like if you want to hear the answer 🙂🙂🙂

@meifert2 6 лет назад

I used to work in a truck shop and in 2 years only saw one melted turbo....the reason for that was a clogged and bent exhaust system and it was dumping oil into the turbo

@jutjub22 6 лет назад

This is a good question, how much materials suffer from added heat to turbo, exhaust pipes. Downsides need to be well tested before putting this on.

@mukundthorat5672 6 лет назад

Oil needs to be tested as well for breakdown around the turbo

@ryanscott3753 6 лет назад

As an engine engineer at an OEM, the only reason why we use the turbo and exhaust blankets is to reduce the temperature of engine components due to radiated heat during "pump tests" to qualify the engines for emergency and military vehicle ratings. The pump test is a btch. Imagine an engine at full load for HOURS with no airflow, other than the cooling fan. Also, imagine the fires that happen when something goes wrong. Holy carp. The scary thing is that with the heat blankets the risk of a catastrophic fire due to oil (or power steering fluid) leans goes UP. The Coast Guard requirements require lower surface temperatures to prevent those fires, There aren't any performance benefits to turbo wraps.

"There aren't any performance benefits to turbo wraps." It would appear that maybe you didn't watch the entire video... Check this link - Turbo Blanket Thesis Source: repositories.lib.utexas.edu/bitstream/handle/2152/43718/BICKLE-MASTERSREPORT-2016.pdf?sequence=1&isAllowed=y Show less REPLY

I did watch the entire video. I don't believe the source. They used a SF-901 dyno, a piece of junk that cannot be used for reliable measurements. The test setup is a bunch of crap. A low-inertia (and inertially compensated) AC synchronous dyno is needed to run those turbo tests. How do I know? I have run those tests, and it is a lot of work to do that type of turbo analysis. The dyno alone costs $400k, and the control room costs 10 times that amount. Some college kids at UT-Austin don't have a fraction of those capabilities. How can a SF-901 perform an inertially-compensated 500 rpm/second turbo test? The little college children don't have the equipment to run turbo tests, and they are so ignorant of turbo testing that they don't even know that they don't know what they are doing. Slapping a water brake dyno on an old Cummins engine means nothing. I didn't see anything in the test setup to accurately measure M-dot. No self-respecting turbo engineer believes that garbage in the UT-Austin test.

@ryanscott3753 6 лет назад

When I ran the turbo tests and qualifications the CAC was a HUGE influence in the tests, not only was the heat transfer rate extremely difficult to control, but the volume of the CAC system was critically important. No respectful engineer would use that K&N filter crap in a dyno cell. The combustion air intake had to be precisely controlled to temperature, barometric pressure, intake restriction, and humidity. A sloppy K&N air filter ingesting "dyno cell air" does none of that. I had to control exhaust scavenge blowers to control for turbine out pressure (curves). Only an ignorant professor would approve such garbage of a test.

@ryanscott3753 6 лет назад

I was looking, and looking, and looking some more for basic information that is necessary to process the data in the turbo tests. Where is Epm_nEng in any of the data? If they had access to the Bosch EDC, where is that information? The CAN data is way too slow for n.

@wheelheroes7902 6 лет назад

Jason, very interesting video, thanks for investigating! So I assume a ceramic coating on the turbo would have the same effect? But that wouldn't be such a bargain 😅 Also, great chemistry between the two of you!

@4drturbo85 6 лет назад

Yeah I don't have a blanket on mine. I think about installing one. But my compressor, exhaust housing, 02 housing and log manifold is all ceramic coated.

@madfiat8932 6 лет назад

Maybe I'm wrong but having a "ceramic coated" turbo myself, I think the effects of ceramic coating are way exaggerated. It's not a magical material.

@admkbldwn 6 лет назад

Ceramic coating isn't exactly insulating... I would think the advantage would just be protection from oxidation at the high temps a turbo operates at

@tomhiggins4816 6 лет назад

The blanket mostly protects against radiative heat transfer, the blanket essentials catches this radiating heat. Once the ceramic coating is up to the same temperature as the turbo it will still radiate heat in the same way as if there was no blanket or coating. maybe slightly less but nowhere near the same amount a turbo blanket would.

@wheelheroes7902 6 лет назад

Tom Higgins well, that does sound logical indeed. Thanks for answering. Have a nice day, guys!

@gwick358 6 лет назад

When I was in school, I was taught that turbos work from heat. More heat in the turbo= more better !

@103798 6 лет назад

Try again, it's all wasted heat and compressing takes way more energy if you keep the heat in. It's the hole concept of an intercooler, or multistage compression.

@nhoff7703 6 лет назад

He's correct. The turbo works from heat. This blanket keeps the heat in on the hot side of the turbo. Also the cool side from being impacted from this heat. It's a win, win. That said. Yes, you want cool dense air on the cool/intake side.

@load7097 6 лет назад

Frank. Turbo intake side vs Turbo exhaust side... We're talking the exhaust side. Watch the video.

@2450logan 6 лет назад

Guy Curwick Damn right! More heat in the exhaust side means more expansion of gases, more gases means more choochoo

@liamcooper5202 6 лет назад

Turbos work on pressure differential. Heat is proportional to pressure in this case. The higher the pressure difference the faster the velocity, the hotter the gas the more it will want to expand through the turbine.

@garycsfunlife 2 года назад

This really helps me with my choice of blanket on or no blanket definitely seems worth it in a A4 B7 2.0T

@worldrallynut 6 лет назад

Thanks for the videos! What you didn't report was whether the turbo bearings were much hotter or closer to the oil temp. If the oil was not capable of extracting the heat due to a short time in the turbo before moving out and getting cooled again before returning the results do support that though they don't monitor it. Since the housing is much hotter and the oil isn't cooling it fast enough, the bearings are probably at a temperature beyond what they would normally operate. It is plausible that in hotter ambient temps, you might exceed the designed bearing temperature and prematurely wear them out.

@pappyman179 6 лет назад

Wow, nice camera (the one filming, not sitting on the bench). Is it new? Also, I love it when you two collaborate. Great stuff guys.

@EngineeringExplained 6 лет назад

That's Charles camera. You're noticing 60 fps vs what I shoot in (4k 30 FPS).

@pappyman179 6 лет назад

Interesting. I usually watch in 720p60, but I wonder if the 60 fps just survives the YT compression better. I was 'seeing' better detail and pixel clarity as opposed to thinking it was an fps thing. With two talking heads, one would question how the fps would change anything. It's not like you're moving much. Hmmm. Anyway, thanks for the reply. Charles adds a lot to your vids, you two work really well together. And as stated earlier, the vid quality was excellent for whatever the reason. Those FLIR shots owned.

@dustinjames1268 6 лет назад

I think it has more to do with Charles using a lower resolution camera (to achieve higher framerates) and the downscaling isnt as significant, so you keep that quality Compression also does have a lot to do with it though, so thats definitely a factor

@CycloneCyd 6 лет назад

Even though I understand the thermodynamics here, I've nevertheless been umming and ahing about a blanket. Thanks for the brilliant explanation. Q: would insulating the compressor side (even without a turbine blanket) help the IAT?

@MichaelBrown-wx6zq 2 месяца назад

You'd be better off putting exhaust wrap on the headers

@fas2gsx 6 лет назад

The turbo blankets do make a difference. I used one when I had a 99 Eclipse GSX running a HTA3076 being only 3” away from the radiator. I was having a lot of heating issues...even with the larger mishimoto radiator. I used the lava turbo blanket from PTP and it made a very noticeable difference.

Jason, the turbo surface temperature increase of 150 C concerns me a little. Would this decrease the longevity of the turbo considering the temperatures are drastically higher?

@Big1_ Год назад

Concerns me too, i don´t use blanket in my turbo, i have installed an air conduct direct to the turbo which gets all the cold air.

@DavidCheung 6 лет назад

Excellent testing methodology! Wish there was a dyno involved, but the study at the end helps prove the hypothesis.

@R8Prototype 6 лет назад

Hmm, so basically similar to ceramic coating headers to keep the heat in and keeping the engine bay temperatures down. Great video!

@Warkid1993 6 лет назад

Do modern cars with after shutoff cooling pumps for the turbo require idle engine cool down? Fiat 500 abarth has a pump that runs if the turbo is still hot after shutoff

@HumbleMechanic 6 лет назад

My GTI has that pump from the factory. This car was also not turbocharged from the factory. I still let it run for a minute or so before shutting it down, then let the coolant pump run until it shuts down.

@z-trip5457 Год назад

This seems useful for a daily that doesnt drive long distances, the quicker that turbo gets hot the better!

@skrame01 6 лет назад

If the turbine housing is 200C hotter, it will be likely to warp more, and more likely for the turbine wheel to rub the housing, causing blade damage and bearing failure. The blade clearance is typically < 0.020". I took measurements once that showed a turbine housing expanded by over a millimeter from thermal expansion. All housings heat unevenly and this causes transient warping and thermal fatigue causing cracks. Be careful.

@skrame01 6 лет назад

One other point to make about messing with turbos, is when they are developed they are rated for certain maximum conditions, not to be exceeded, and it's important that you don't. An average turbine wheel at maximum rated speed contains more than 25kJ of rotational energy; 2x the energy of a 50cal bullet. The maximum speed of the blade tips is > 2000 ft/second (1400mph), faster than the muzzle velocity of most handguns. If you run the turbine housing beyond its qualified temperature, it may be weakened and may not contain a turbine wheel burst. Turbine wheels can literally split in half if oversped or the temperature too high and is cycled too many times. The turbine wheel can also separate from the shaft, and be ejected from the turbine housing outlet, which happens to be pointed back at you, and roll around at the remaining speed of the wheel, potentially hundreds of mph. Just so you know. Be careful, these are powerful machines.

@kam_iko 6 лет назад

the turbo radiating heat into the engine compartment makes my engine heat up faster. i like that! especially in winter :)

@HumbleMechanic 6 лет назад

We proved that with in cab temps too. Not fun in the winter for staying warm

@kam_iko 6 лет назад

Jason it heats up faster in summer too! :D it’s a transportation vehicle (golf vi 1.4l 118kw (turbo+compressor)), not a sports car, so the engine cooling takes care of that without any problems.

@CycloneCyd 6 лет назад

Not at all. If you're running your engine hard enough to get your turbo really hot before the engine has reached normal operating temp, then you're asking for trouble.

@affordablepropertymaintena9213 6 лет назад

Kamil turbo doesnt heat up untill it spools up under boost. So your theory is wrong.

@Hoonbernator1590 6 лет назад

That's not right. The turbo heats as the engine heats, with the exhaust flushing through. Sure, it doesnt hit peak heat till you're in high spool, but it would hit average heat without hitting the boost threshold.

@m43_felix 6 лет назад

But may this blanket increase turbo wear ?

@DejaVu19711 3 года назад

Thanks A Mill Bros, This Is Info I Craved. Now I'll Need A TPT Turbo Blanket .... When I Do A Turbo Build

@imoffendedthatyouareoffended Год назад

Something I’ve been considering, I live in Vegas, during 9 months it’s normal feels great, but when it goes above the 90’s it starts losing power. I don’t want a front mount intercooler, I mean let’s be real the hood scoop is fun. :D I’ll install a bigger better tmic eventually, but a turbo blanket seems like it might be able to help my issues.

@stevenp3176 6 лет назад

Other than quicker spool wouldn’t the waste gate keep the boost the same?

@EngineeringExplained 6 лет назад

The wastegate can control peak boost, yes. But how fast you get up to peak boost is not controlled.

@stevenp3176 6 лет назад

Right that's what I figured. When you guys were talking about peak boost it sounded like you were implying that peak boost would be changed. Thanks for the reply keep up the great videos please.

@robertmontgomery7158 6 лет назад

So why don't the OEMs use Turbo blankets???

@EngineeringExplained 6 лет назад

It's a great question - it could be cost, it could be designing the turbos for specific locations, could be from using relatively low boost. I'm not 100% sure.

@aussiebloke609 6 лет назад

I have to suspect cost as the culprit - a small price per car, but it adds up with volume (rather like that airline that saved millions by using one less olive in each salad.) OEM turbos are running up to 18 psi of boost, sans blanket - considerably higher than the 12 psi on this car. However, it seems they're mounting them low on the back of the engine, up against the firewall...so presumably the airflow is removing the heat as it flows under the car before it can heat the engine bay too much. That's obviously a guess, but it has to be better than squeezing it in between the radiator and engine in the classic manner, where the heat can flow over the entire engine (including the intake manifold) before it can exit the bay.

@madfiat8932 6 лет назад

Also turbo blankets are porous and could easily become dirty, or worse oil soaked in case of oil leaks. Of to gets oily, it could be a fire hazard. Car guys would hopefully keep it clean, but grandma would never notice until she had a fire.

@ChuckLZard 6 лет назад

Well that blanket is $140 on amazon. While economy of scale would definitely apply a part anywhere near that expensive is ridiculous when you can get a serious chunk of that using your standard metal heat shields. Another thing that I saw mentioned is the increased temperature on the exhaust piping leading out of the turbo (to the tune of more than 100C). So you would essentially be trading high temperature parts upstream for downstream. Depending on your layout that may be beneficial, but it's certainly not an always better scenario.

@ajsylvia9823 6 лет назад

Id like to see a comparison of the turbo outlet pipes to the intercooler wrapped vs unwrapped in addition to the turbo blanket . I have a 88 7mgte supra where the intercooler inlet and outlet are very close to the turbo(I believe that the benifits of insulation on the ic piping will be huge for this particular intercooler design)

@alexmoore5970 6 лет назад

Can you make a video about that oil shield, between the hot side and the cold side of the turbo. Or at lease provide me with some type of literature.

@daviddroescher 4 года назад

Tip for all: high temp 2000°f ceramic paint under wrap/blanket to prevent rust. And over to help seal in fibers, and keep things like oil spills/drips from soaking in ruining the wrap /blanket. And don't just throw blanket on it wrap that sucker all the way to the Head. There's more low-hanging fruit in improving the effectiveness of a turbo.

My 9-3 Aero had to have basically a blanket or basically additional thermals for the turbo because it was melting other parts of the engine on at least the 2.8l V6 versions. So this makes perfect sense for me.
