Hahahaha. I like that explanation. How they work though is by slamming more air into your cylinder. More compression means faster ignition. faster ignition means more sack in the low end ( and a bit on horse power too), producing faster exaust gasses that spin the turbines and repeat the process. Pretty cool devices. If thinking about installing one though, remember, EVERYTHING down the line that is stock will be put under more stress than it should be under and things that cant take it WILL break. So remember, when putting more power, make sure your stuff can take it! And rev limiters? fuck those things. The yare like fun limiters, amiright?
det414 its all the market man, its stupid but there cost percentage is around 70% which is 40% more than TVs but ya.. they are overpriced, i got my t4 at a junk yard for 50 bucks
BUDDHA BLESS Turbo Diesel. Makes heavy duty engines more powerful and efficient. They're also on big trucks. Kinda doubt they spin up to 100k rpm though, since they're bigger than turbos found on smaller cars, I believe.
Zac Jones The real reason is that sand is too impure, you can't have a natural material be 100% smooth and uniform 100% of the time. Man made "sand" guarantees that the mold will come out perfect every time, which is needed on something as precise as a turbocharger.
Wow the other comments here are genius. The intake side is cast aluminum for the housing usually with a harder metal for the wheel. Using aluminum on the exhaust side would quickly leave all your dreams of going fast in a puddle of molten metal.
I worked on developing a machine that automates the repair process for turbocharger impellers. It uses a laser to build up repair material onto the turbine impeller and nozzle guide vane, in order to salvage parts subjected to foreign object damage Those impellers are sometimes made from nickel superalloys, making them a bastard to weld conventionally.
It's nice to see how exactly turbochargers are made. I've always had a rough idea, and know how they worked, but the whole sand casts is definitely a new to me, and cool part of the process.
It takes "15 minutes" to assemble all the parts that are made specifically for this application. Meaning it cost thousands to produce. From raw casting to completely assembled turbo charger, takes many man hour collectively.
"Helps small engines compete with large ones with out guzzling extra fuel" if you turbo anything with out adding "extra" fuel coming from A naturally aspirated engine your gonna have a bad time :/
I mean if the engine never sees that boost, i.e. wastegate valve is completely open or removed altogether lmao. Hell, I wanna see how the fancy EFR snails are built!
Yes. Except diesels don't play by the same rules, which is why even under boost they get better fuel economy than a diesel with no turbo. A gas turbo engine, on the other hand, is less efficient at power peak than a similar naturally aspirated gas engine.
+richardxeelee tell that to Sir Humpry, as he was a British chemist who couldn't make his own mind as to how to call this -new a the time- element. Aluminum is more sexy name.
+richardxeelee It's "Aluminium" if you're a Brit; "Aluminum" to everyone else. Just kidding; to be fair, "Aluminium" is the world-recognized name (acknowledged by educated Americans but rarely used), but say that word anywhere in the US (especially in aircraft-related businesses) and you will likely be the subject of seemingly endless ridicule.
The first jet motors used by the allies like in the Gloster Meteor were simple centrifugal pieces more like a large fuel burning turbocharger. And actually turbochargers were used to prevent negative G stalls and raise service ceilings on carbureted aircraft engines as much as for added power. Allison had a two in one super/turbocharger on their engine that was way ahead of its time.
Thanks man, Glad you and a couple others are helping me understand this completely, I like to know what I'm talking about when talking cars with others less familiar with cars. Even when the less familiar is myself at times. Lol
ya I get the price assuming they're paying off all that fancy milling and balancing equipment. But if that's all paid for then shit that's a big profit margin.
ThomasRocksU yeah but they don't sell like lolly's lol, mostly for wages and running cost then transport cost to the seller to which the seller wants to make money.
Yes, the bearing is a hydrodynamic journal, as the shaft spins faster the oil pressure increases and makes a better bearing. Some turbo chargers now have ball bearings but they still require constant lubrication.
This was totally useless should have been titled "how a turbo housing is made and turbo assembled" because that's all it shows. It doesn't show how turbines or bearings or center housings are made or anything useless.
I'm talking about the turbo INTERNALS. The count of the blades, the angles, the shape, the orientation, there are quite a few trade secrets in the turbocharger business
you cant get any exact info that would be required to copy one from a video. Particularly not any more than you could get by buying one. Pretty much needless to say, but if anyone actually posed a threat of copying trade secrets, I would very much hope they could at least afford to buy one turbo to measure. Therefore making a video
TheRealestEver The correct way is alu-mini-um, but we're American, so we do things differently for no apparent reason other than being American, such as still using the Imperial system instead of the Metric system. As a result, Aluminum is proper in American English only; Aluminium is proper internationally, including England, that country from which our language is named after and originated from. So please, if you're going to say it, say it correctly: Alu-mini-um.
There is a claim that Karl Joseph Bayer, who discovered it, called it Aluminum, and that at the time, the English thought it would sound better with the "ium" ending which was becoming popular with newly discovered elements at the time. I've been unable to find an actual source for this though. "um" is technically just as valid, like platinum.
No, because they show how it's made from scratch; from the molds, to the parts and to the assembly itself. Of course, they don't show how every part is made but still.
Saab used to make their highest model of 9-5 in 02-05 a 4 cylinder turbo that pushed 250 horse. the lowest end was the same engine with a lower end turbo that got 185 horse. the middle one was a 6 cylinder with 700cc more displacement and it only got 200 horse with the same turbo as the lowest model. the two 4 cylinder models had the same fuel economy as eachother and the 6 had about 2/3 the fuel economy of either. there is no replacement for displacement, but turbos increase the max potential
The reason for this is that the factory ecu calibration keeps the a/f ratio very rich on these cars when your in boost, plus the timing map is very conservative also to provide a safety cushion against detonation if people choose to use regular 87 octane fuel. This makes the engines with a factory calibrated ecu have to work harder and rev out to higher RPMs in order to accelerate the vehicle which uses more fuel than it truely needs.
To those complaining about the cost for what takes 15 minutes to build: I used to work in a Saab specialty shop, The most common failure we saw (aside from bearing failure from improper maintenance and cool down) was the exhaust side cast iron housing would crack. The housing was so expensive that people would gladly pay us to braze the crack shut with absolutely no warranty. The turbo cartridge was fairly cheap for a precision item, but those hand made sand cast housings were horribly expensive...
few compressor wheels are 5-axis machined and all the aerodynamics is more a modern thing. at one time it was common to see strait blades so anything curved was an improvement, the more math they apply the better. most turbo parts are cast and the finish machining is done on 2-axis lathes. the complex shapes of the compressor are molded in wax from molds that are either complex or flexible so that the wax releases. the wax is dipped in a slurry to make a shell then wax is melted out.
Peenut Gallarry "Compressed air means you are able to achieve a bigger 'bang' with the same amount of gasoline. So a turbo charged 2 litre engine can reach the power level of much larger engines without having to add more gasoline." That is exactly what the guy at 0:38 probably meant but apparently the message can be missunderstood into the worse.
You sir are correct...apparently no one else is listening...I understood what he meant as soon as he (the narrator)said it...they didn't get it because they don't really know how a turbocharger works. Well said...
To small of a company, to feel comfortable giving it's name (for me to stay anonymous). Re-manufactured: Rajay, Garret, Holset/Cummings, BW. I'm like a Jack-of-all-turbos. Some are easy, some are a pain. Small ones, big ones...some twice the size of your head. I don't touch many of the VGs ones, but I have (they take a lot more time).
what your talking about is called "sequential" turbos twins turbos are both the exact size and volume hence being twin, but do still typically spool faster than on large single turbo but don't usually put out as much boost as a single, a sequential setup tries to address both issues but is very difficult to tune.
basically. the turbo bolts onto an exhaust manifold which goes on the motor. you can find exhaust manifolds for basically all types of cars. but turbo charging a car requires a LOT more work than just hooking up the turbo.
from what ive seen the air goes to one turbine at a set speed causing it to quickly spin. the rod causes a large on to spin at the same speed and cause the air to compress itself.
In SOME situations (mostly at low-mid throttle) a turbocharged engine is more efficient because you're using exhaust energy to do the air pumping where a NA engine would have high pumping losses (the energy to pump the air is taken from the crank and at partial throttle it's worse because of the low intake pressure).
Finally someone actually read what I writed. It maybe can save a bit but that's not what it's made for. That you can actually say "yea I got turbo, I save gas with turbo engine." Just made for higher power output from engines, not gas savings.
Turbos can save fuel somewhat. A lower-compression engine has lower pumping losses and higher efficiency when cruising/idling, but has poor efficiency when driven hard. A turbocharger raises the effective compression ratio allowing it to burn fuel more efficiently.
It is a device taking the pressure from the exhaust to increase the pressure of the air going into the engine. This allows the engine to combust more fuel, wich in return give you more power. If you also cool the compressed air you can get a better fuel economy for thermal dynamic reason (wich I cant explain in 200 caracters)
amazing how the knock off turbos are 125 bucks and work just fine-did notice these ones are assembled a bit differnt in that they have a bolt on thrust washer you can buy one though for about 70 bucks drill and tap-im getting pretty good at ripping apart and trying differnt combos-i just bought a godspped one that cant wait to try 259 shipped-thanks for the video -super nice
not to mention all the guzzling, spraying into a cavity, plugging the hole, rocking the box, aiming a flame at a hole in the box, inserting the shaft, pushing it further down the shaft...
Yes about 15 minutes to assemble one. That does not include the foundry process of sand casting the molds, finish machining etc. Not to mention the millions of dollars in equipment for the foundry and the final machining that goes into the production. Amazingly enough the turbocharge is still only around 2-3k. Lucky for us they can sell enough to mass produce them hence the cost savings.
An aluminum can would cool very quickly, because it is extremely thin and doesnt have much mass, lots of surface area to dissapate heat. The aluminum foil in the oven doesnt get hot, because it is reflecting the heat with its shiny surface. this is from a source "The molten aluminium takes considerable time to cool down, and the component cannot be removed from the mold until it had cooled and hardened."
This is actually a fairly common fallacy regarding turbos; that they somehow "harness" the "unused exhaust gasses" to power the engine. In reality, the relationship is much more akin to that of a shoveler shoveling coal into a steam engine; the turbo simply allows the engine to burn more fuel, thereby producing more power.
You're thinking about taking a given engine and fitting a turbocharger, but look at it from a manufacturer's POV: for a given torque/power output, you can have a larger NA engine or a smaller turbo'd one. For say half that max power, the NA engine will be at part throttle (pumping losses), while the turbo'd engine with electronic boost control can be at WOT but no boost (virtually no pumping losses). Also at WOT the turbo can still improve volumetric efficiency, especially at low RPM.
They could have easily made this a 5 hour video if they fully explained this whole manufacturing process. Design, mold making, numbers, research, turbine design and construction..etc.
A lot of people don't like newer cars. Older cars like the Integra are much simpler and easier to play with and tune. And the feel you get from driving older cars such as the Integra with a mechanically linked accelerator pedal to a real throttle body and a manual transmission that doesn't feel completely synthetic that doesn't have dual mass flywheels or dual clutches that make driving dull. Also no traction control systems doing all the driving for you. They just offer a better experience.
takes 15 minutes to make, but takes hours to install >.

A turbo: exhaust gasses go into the turbocharger and spin it, witchcraft happens and you go faster
Hahahaha. I like that explanation.
How they work though is by slamming more air into your cylinder. More compression means faster ignition. faster ignition means more sack in the low end ( and a bit on horse power too), producing faster exaust gasses that spin the turbines and repeat the process. Pretty cool devices.

+sidgar1 that's right. turbos for trucks and busses are much bigger.
Next time you're on the beach, or enjoying an hour glass, just think where we'd be without SAND.
This isn't the same kind of sand you find at the beach or in an hour glass at all, It's specialized man made stuff.

No, but the programs to run the machines and make the components are.
It aggravates me how Americans pronounce aluminium, It's aluminium not aluminum
It is not. Aluminum. We won the war so our way is correct over yours.

The reason for this is that the factory ecu calibration keeps the a/f ratio very rich on these cars when your in boost, plus the timing map is very conservative also to provide a safety cushion against detonation if people choose to use regular 87 octane fuel.

The turbo cartridge was fairly cheap for a precision item, but those hand made sand cast housings were horribly expensive...
that's actually really good considering overheads and machinary cost aswell. the retail price is around 4x manufacturing cost for most products.
Essentially, the turbocharger gets it energy from the exhaust gasses. Those gasses spins the mechanism which in turn compresses intake gasses.
few compressor wheels are 5-axis machined and all the aerodynamics is more a modern thing. at one time it was common to see strait blades so anything curved was an improvement, the more math they apply the better. most turbo parts are cast and the finish machining is done on 2-axis lathes. the complex shapes of the compressor are molded in wax from molds that are either complex or flexible so that the wax releases. the wax is dipped in a slurry to make a shell then wax is melted out.
That's a pretty freakin awesome process!

Man that's amazing stuff hey!
And the added efficiency is a bonus too...
I get to build turbochargers all day. They only take 10-20min/each to put together once you have all the correct parts.
That's cool, for what company?
+Hot Rod Lincoln probably garrett turbos they make them in house not around town like most comapnies.
To small of a company, to feel comfortable giving it's name (for me to stay anonymous). Re-manufactured: Rajay, Garret, Holset/Cummings, BW. I'm like a Jack-of-all-turbos. Some are easy, some are a pain. Small ones, big ones...some twice the size of your head. I don't touch many of the VGs ones, but I have (they take a lot more time).
i love snails they can go as fast as they want

Sweet! Now I know what to do with all the sand here in FL and all that molten aluminum I have laying around!
god those turbos look amazing
from what ive seen the air goes to one turbine at a set speed causing it to quickly spin. the rod causes a large on to spin at the same speed and cause the air to compress itself.
Great video!
In SOME situations (mostly at low-mid throttle) a turbocharged engine is more efficient because you're using exhaust energy to do the air pumping where a NA engine would have high pumping losses (the energy to pump the air is taken from the crank and at partial throttle it's worse because of the low intake pressure).
Super vidéo très instructive.
thanks for the video man! now i know how to make turbocharger...i'll make one for my car
All this has taught me is that if you can be arsed you can make your own
Yeah that first one that was put in was a bushing, it was solid metal. The second one was a bushing, i noticed, though.
Finally someone actually read what I writed. It maybe can save a bit but that's not what it's made for. That you can actually say "yea I got turbo, I save gas with turbo engine." Just made for higher power output from engines, not gas savings.
good video for rebuilding a turbo.
Turbos can save fuel somewhat. A lower-compression engine has lower pumping losses and higher efficiency when cruising/idling, but has poor efficiency when driven hard. A turbocharger raises the effective compression ratio allowing it to burn fuel more efficiently.

If you also cool the compressed air you can get a better fuel economy for thermal dynamic reason (wich I cant explain in 200 caracters)
The green substance applied on the bearing is not a lubricant, it is a bearing fixing compound.

incredible! it takes the engines shit and turns it into power. incredible!
And on the note of F1, in the years when they had a mix of turbo and NA engines, the turbos dominated.
this would be a really cool summer job
Love it,great for newbies(me)

Very cool
This is actually a fairly common fallacy regarding turbos; that they somehow "harness" the "unused exhaust gasses" to power the engine. In reality, the relationship is much more akin to that of a shoveler shoveling coal into a steam engine; the turbo simply allows the engine to burn more fuel, thereby producing more power.
It was somewhat tongue in cheek. He was just express a sentiment about the expense of turbos.
It's amazing
When he said: "He inserts the shaft," I lost it. LAWL
and they make a diesel truck sound even more awesome. 7.3L Ford Powerstroke Diesel FTW!

+FireFighter#47 Diesel trucks need turbos to run.
No they dont. Have a look at the Ford 6.9L IDI Diesel engines, as well as the 7.3L IDI Diesel engines.

and a 7.3L with a tune is slower than a 99 Ford Taurus... I know from experience.
A truck isnt about speed. its about torque!
Awesome ... Amazing ... like
Nice video
You're thinking about taking a given engine and fitting a turbocharger, but look at it from a manufacturer's POV: for a given torque/power output, you can have a larger NA engine or a smaller turbo'd one. For say half that max power, the NA engine will be at part throttle (pumping losses), while the turbo'd engine with electronic boost control can be at WOT but no boost (virtually no pumping losses).
Also at WOT the turbo can still improve volumetric efficiency, especially at low RPM.
They could have easily made this a 5 hour video if they fully explained this whole manufacturing process. Design, mold making, numbers, research, turbine design and construction..etc.
A lot of people don't like newer cars. Older cars like the Integra are much simpler and easier to play with and tune. And the feel you get from driving older cars such as the Integra with a mechanically linked accelerator pedal to a real throttle body and a manual transmission that doesn't feel completely synthetic that doesn't have dual mass flywheels or dual clutches that make driving dull. Also no traction control systems doing all the driving for you. They just offer a better experience.
"He rocks the box."
Hells yeah he does!
Good video.
awesome!!
