What do you mean the turbo takes air in at 14psi????and puts it out around 25psi higher??? Go get yourself the book by HP books, its called turbochargers.
@dooalittledippsy 14 psi is the pressure of air at sea level otherwise known as atmospheric pressure..... so 25 pounds of boost would be 25 psi HIGHER than atmospheric pressure which is 14 psi. go get yourself an education before telling people to read books.
You can install turbos on most engines, BUT the engine may not be able to handle it.
Wastegate is spring loded, not Comp comtrolled. Please learn more about this BEFORE you post a video. Videos like this are why so many dumbass ricers have exploding engines...
@melisevo you can install a turbo on any car, but u cant just bolt it on,and expect it to work-do your own research, and start saving some money up. ;) lol
@broken4813 I'm confused by your question. Fuel Injected engines, diesel or gas, will generally run a throttle body. Wastegate is not application specific, it's just a spring loaded "escape hatch" to allow the exhaust gases to bypass the spinning shaft, allowing it to stop creating pressure. Otherwise, boost would be created based on engine RPM. Higher RPMs higher pressure, endlessly, which could cause a lot of damage from "overboosting".
good video, u explained it backwards in my opinion since the exhaust side is what drives the compressor wheel on the intake so it would make more since to start off with that.
Turbos aren't only for imports. The American made SSC Ultimate Aero has a 6.3L Twin Turbo'd V8 with 1287hp and over 1100ft-lb Torque. Does over 250mph.
@mightbleed let me say this.. evo's 8-10 have iron engine blocks (good for boost), forged pistons from factory (almost a must have for boost higher than 1 bar), stronger connecting rods, and forged cranks. When pushing more air through an engine fuel becomes increasingly important because if your A/F mixture gets too lean.. BOOM. Most evo, sti, turboed or supercharged car owners make sure their fuel systems are very well equiped to handle more boost. its all how much you want to spend :)
Thank you mate. That was an awesome explaination. Kind of had an idea quizing people about turbos, but now I have a complete picture in my head...AND learnt what "intercoolers" and "blow off valves" do in the process. Kind of makes me want to strap one on my 87 ford laser....just so I see it detonate. Muhahahahaha.

@nitrojunkie1029 Again, contrary to the dumbass that posted this video, that isn't really a lot for those motors. I had a 2002 that would spike up to 26 on the stock turbo, but the efficiency drops dramatically after something like 16psi. You also have to remember volume; the tiny K03 on the GTI doesn't have a lot of volume so it's compressing less air than a bigger turbo at the same psi level, which is why a big turbo increases power that much more.
Exhaust driven turbos arent the only ones btw... There are V-Belt driven turbos as well which have no power loss on low revs. I think u call them supercharger right?
But exhaust driven turbos are more common, cuz theyre easier to apply on the engine.
well an engineer your not. But at least you show a pic of the best aussie car ever made @ 6:18 The all australian ford xr6 tubo.It's a 4L inline 6 with a garret 35/40 turbo. The pic shows one with a big plazmaman intercooler with pipe kit good for over 400rwkws
ok I have to correct everything said here. first off an average psi rating for a turbo is 8 not 30. Second the turbo isnt designed to spin air around and make it move faster. it is designed to cool the air and compress the air into the cylinder. more air means the engine has to use more fuel to compensate Which when ignited creates more TORQUE than stock. Horsepower is a unit of (in simple terms) Force/time(lb.ft per minute) Horsepower is the average slope of the Graph of the torque curve
@duxante the shaft speed of a turbo is very high, very high indeed :) the internal working parts have to be machined to very fine tolerances, and that costs money... plus its a good idea to make further modifications to the engine, so you can get the most out of it... that costs too.. :-) and if power is your goal when fitting a turbo, you get that power cos you can burn more fuel, and that costs even more.. :(
To dragontaco: you're ok? Exhaust gases are wasted anyways plus they have high speed to spin the turbo, if you use supercharger or electric charger you will lose lots of power to spin it, plus no superchargers can get you that high boost
I don't get it. Why need to use exhaust gases to run turbine, when turbine can be powered mechanic ally directly from the engine or electrically. I think exhaust should be as free as possible to allow "bad" gasses to leave the combustion area and turbine would be standing on it's way. Anyone to answer?
@DragonToko Using the exhaust gases allows you to capture lost kinetic energy and use it to pull in more air to produce more power. If you were to connect the turbo to the engine (aka supercharger) then there is a parasitic load. You lose power by rotating the supercharger, where as a turbo does not have this problem.
@asre2001 More effective at low rpms, but not more efficient. It's running off the engine belt rather than using the momentum of exhaust gas (wasted work).
@asre2001 supercharger is driven directly from engine uses power. put to fans facing each other plug one in turn it on both fans will spin. super is like plugged in fan, it uses power. turbo is like free fan, uses air flow from plugged in fan to spin. also basically how a torque convertor works.
@CeeEmmz you would have to do some research on inducer and exducer size, AR, and things like that. Honestly, its not worth it. The system would cost more than 3 tercel engines.
@deccno oh trust me im way ahead of thinking when it comes to performance as a touge fan i believe more in handling performance than speed... "aint tryna be cocky or anything" but yea i feel u on what u say... SPEED AND HANDLING - TOP 2 important and i mean very important things when tuning a car....
@CeeEmmz yes must hobby tuners build themselves a really nice engine drive flat out first time and land in the tree and wonder why. It happens more often than most think!
@deccno cuss they just think about going fast no handling performance what so ever lolz.... yet like what i said "as a touge fan i rather concentrate more on handling performance than speed so i know my car can control its speed" :)
@TheUtubeEngineer So basicly, it's just using the gases from the engine to spin the turbines, shooting the gases out propelling the car forward? I'm sorry, I'm ust a little confused.
@ICEWOLF7600 no its using the exhaust from the car to spin a turbine that forces more air into the engine. As we all know, more air = more combustion which intern gives you more speed.
and when you have a long intercooler, the air gets more cooled, but the compressed air have alonger vau to travel, so it also loses its compression a bit.
Dear Mr. Buchi in order for air to flow at the most extreme you need 1 to have the intake area to be as large as possible, why is the intake so small? 2 Why are you having the air turn 90 degrees!!???? lol 3 You are causing a back pressure on the gasses on the cylinders that are trying to exhaust the gas! Don't you want more air flow through the engine. 4 But worst of all, why do you have such small bearings? The bearings should be on the outside of the fins, and the air flow should be straight
I think the term you missed out is "volumetric efficiency" and "misfire". You also missed the point that petrol engine runs at lower temperature as compared to diesel engine. There were precombustion chamber in older diesel engine and heat plugs to heat up the air in the combustion chamber. petrol engine uses spark plug for combustion stroke. Bottom line: most diesel engine do not need intercooler (heatsink).
@rippedshoes911 not always faster, but there is a potential for more speed at the output of a reciprocating engine is in fact increased. the intake pressure in increased so more pressure difference inside and outside the cylinder during the intake stroke increased the amount of air avaliable for combustion, thus increasing potential fuel burn and ultimately more power.
@rippedshoes911 engines create power by creating controlled explosion... the piston compresses air and fuel in the cylinder and ignites the fuel air mixture. the more air and fuel that can be forced into the cylinder at one time, the greater force of explosion and therefore more power. this process is called forced induction if you would like to read more.
@1DavidSe correct for the most part, but although the increased intake pressure does increase compression and overall thermal efficiency, the extra air most importantly increased the potential for volume of fuel to be burned at the correct stoicyometric relationship, rather than the "more powerful explosion". although it does result in this. thanks for posting!
@TheUtubeEngineer You are telling me there is no such thing as a negative pressure. In the beginning of this video you explain that atmospheric pressure is +14 pounds. if you want to explain how things work get it straight. boost gauges measure air pressures if the car is off it reads 0, running -14 and if under load reads a positive #. This is a pressure gauge that reads positive and negative air pressures. by that logic why dont i just say boost is boost there is no such thing as positive psi
@1DavidSe that is right, there is no such thing. you cannot get lower than 0 psi. you are mistaking gauge psi for reality. gauges read 0 at atmospheric, which is 14.7 psi. so if you were running 8 pounds of boost, the gauge woud read 8, but in reality there would be 22.7 pounds of pressure forcing air into the cylinders.
This process in which the air reaches a lower volume at lower temperatures is given by the fact that its an isobaric process, which is the most common type of process found in internal combustion engines.
Excellent video. Just got a couple of simple questions.
1. The compression that is measured in the turbos (as in a turbo running 10psi or 20psi) is the pressure on the turbine or the compressor?
2. The wastegate is actuated on the turbine or compressor? I think you showed an internal wastegate if im not mistaken. What about external wastegates?
@physicsguy91 When one is running a boost gauge, it displays the boost pressure, or rather the pressure of the forced air on the intake side of the engine, after the compressor wheel.
2. On free floating turbos, there is no wastegate. These are usually found on very large engines. When exhaust pressure increases turbo rpm, and then the pressure drops, aka, take your foot off the throttle, the air on the intake is at higher pressure than the exhaust side, causing backflow of cold air through
@physicsguy91 the turbo. this is known as turbo chatter. most turbos with wastegates however, do not vent the exhaust gas to slow the flow of pressurized intake air. instead, it blows off excess volume of air on the intake side should the pressures become uneven. this turbos differ in that some vent the air directly oustide the whole system, or some vent the excess back in the system only in front of the turbo. either way, turbos either dont have wastegates, or they are acutated electronically.
@TheUtubeEngineer Thanks for the explanation, recently I read some technical info on Garrett's turbo's website and with your explanation now I have a global perspective of turbos, ratios used and also compressors maps... looking forward to install a T28 on a nissan sentra lol
A cubic foot of air is a cubic foot. No matter what temperature. The colder the air the closer together the molecules, thus more dense. More dense means more oxygen, and more oxygen means more burn.
Hey man, one way or another people are gonna hate... whether or not your pressure numbers are completely accurate or not, your overall demonstration was both very informative and clear. I've watched several youtube presentations on turbochargers, and they all left me with questions afterwards.... This cleared up a lot of ambiguity. Thanks man, great job!
@cahern4041 thank you for your comment, it was very refreshing to see and im glad that my video is attracting some intelligent people, if you have anymore questions or points i left out, please send me a message i will fix everything. thanks again! =)
hot air actually has greater volume then that of cool air...this is how hot air balloons work....watch?v=Z0F3q1ZCwf4 <-----what happens when air is super cooled in a balloon
@miasmablk i dont know what you are talking about it may have more volume but ts less dense so basically in a cold cubic centimeter of air is actually ore air than a hot cubic centimeter of air... therefore you have more air within less space ...
An intercooler is really called a charged air cooler and not a radiator. also it can act as a restriction to the air pressure vs a gain... If the piping is too long or makes abrupt turns. Thats for a front mounted charged air cooler. a top mounted like seen on some models of Subarus etc.. have advantages and disanv. Adv. shorter distance air has to travel. Dis. Heat rises and engine heat onder the hood goes UP (around the "intercooler") therefor decreasing efficiency.. little things to consider
Not to hate.. But dude your explanation and knowledge is NOT necessarily acurate. Your throwing around numbers that dont pertain to any old turbo charger. 35+15 PSI=50 PSI of boost!! ... If you had 50 PSI of boost you would blow your engine within ten seconds. I've seen a ford focus engine block explode on the dynomometer with 25. With those numbers you better have a fully tuned performance head, valve train, header. intake manifold, Ported E and I on head, 3-5 angle seat matching. . . . .
@ebu1mp yes, forgive me if i did not specify that this was for DIESEL engines, obviously that run at compression ratios far beyond gasoline, and can easily handle 50 psi of boost.
I want to know everything about cars and engines. Can anybody suggest any books to read?

@TheUtubeEngineer So basicly, it's just using the gases from the engine to spin the turbines, shooting the gases out propelling the car forward? I'm sorry, I'm ust a little confused.
ICEWOLF7600 5 months ago
@ICEWOLF7600 no its using the exhaust from the car to spin a turbine that forces more air into the engine. As we all know, more air = more combustion which intern gives you more speed.

and when you have a long intercooler, the air gets more cooled, but the compressed air have alonger vau to travel, so it also loses its compression a bit.
TheFullyOmniscient 5 months ago
Dear Mr. Buchi in order for air to flow at the most extreme you need 1 to have the intake area to be as large as possible, why is the intake so small? 2 Why are you having the air turn 90 degrees!!???? lol 3 You are causing a back pressure on the gasses on the cylinders that are trying to exhaust the gas! Don't you want more air flow through the engine. 4 But worst of all, why do you have such small bearings? The bearings should be on the outside of the fins, and the air flow should be straight

@tiredfingers99 he didnt make the turbocharger
TheFullyOmniscient 5 months ago
I think the term you missed out is "volumetric efficiency" and "misfire". You also missed the point that petrol engine runs at lower temperature as compared to diesel engine. There were precombustion chamber in older diesel engine and heat plugs to heat up the air in the combustion chamber. petrol engine uses spark plug for combustion stroke. Bottom line: most diesel engine do not need intercooler (heatsink).

so turbochargers make cars fasters by putting more air pressure into the car right? pls help me
rippedshoes911 6 months ago
@rippedshoes911 not always faster, but there is a potential for more speed at the output of a reciprocating engine is in fact increased. the intake pressure in increased so more pressure difference inside and outside the cylinder during the intake stroke increased the amount of air avaliable for combustion, thus increasing potential fuel burn and ultimately more power.
TheUtubeEngineer 6 months ago
@rippedshoes911 engines create power by creating controlled explosion... the piston compresses air and fuel in the cylinder and ignites the fuel air mixture. the more air and fuel that can be forced into the cylinder at one time, the greater force of explosion and therefore more power. this process is called forced induction if you would like to read more.

@1DavidSe thanks bro
rippedshoes911 6 months ago
@1DavidSe correct for the most part, but although the increased intake pressure does increase compression and overall thermal efficiency, the extra air most importantly increased the potential for volume of fuel to be burned at the correct stoicyometric relationship, rather than the "more powerful explosion". although it does result in this. thanks for posting!

a turbocharger takes air in at a negative air pressure ie a vacuum - negative 14psi
1DavidSe 6 months ago
@1DavidSe a vacuum is a vacuum, there is no such thing as "negative psi."
TheUtubeEngineer 6 months ago
@TheUtubeEngineer You are telling me there is no such thing as a negative pressure. In the beginning of this video you explain that atmospheric pressure is +14 pounds. if you want to explain how things work get it straight. boost gauges measure air pressures if the car is off it reads 0, running -14 and if under load reads a positive #. This is a pressure gauge that reads positive and negative air pressures. by that logic why dont i just say boost is boost there is no such thing as positive psi
1DavidSe 6 months ago
@1DavidSe that is right, there is no such thing. you cannot get lower than 0 psi. you are mistaking gauge psi for reality. gauges read 0 at atmospheric, which is 14.7 psi. so if you were running 8 pounds of boost, the gauge woud read 8, but in reality there would be 22.7 pounds of pressure forcing air into the cylinders.

@TheUtubeEngineer so even when the car is not in "boost" say a reading of 5vac is turbo is adding power to the engine or no?

@1DavidSe indeed, as most intake system have a gauge vac pressure of "negative" 10-8

@MrFishdale depends on which model you get, and what modifications you do to the vehicle if it is normally naturally aspirated.
TheUtubeEngineer 6 months ago
This process in which the air reaches a lower volume at lower temperatures is given by the fact that its an isobaric process, which is the most common type of process found in internal combustion engines.
physicsguy91 7 months ago
Excellent video. Just got a couple of simple questions.
1. The compression that is measured in the turbos (as in a turbo running 10psi or 20psi) is the pressure on the turbine or the compressor?
2. The wastegate is actuated on the turbine or compressor? I think you showed an internal wastegate if im not mistaken. What about external wastegates?
Thanks
physicsguy91 7 months ago
@physicsguy91 When one is running a boost gauge, it displays the boost pressure, or rather the pressure of the forced air on the intake side of the engine, after the compressor wheel.
2. On free floating turbos, there is no wastegate. These are usually found on very large engines. When exhaust pressure increases turbo rpm, and then the pressure drops, aka, take your foot off the throttle, the air on the intake is at higher pressure than the exhaust side, causing backflow of cold air through
TheUtubeEngineer 6 months ago
@physicsguy91 the turbo. this is known as turbo chatter. most turbos with wastegates however, do not vent the exhaust gas to slow the flow of pressurized intake air. instead, it blows off excess volume of air on the intake side should the pressures become uneven. this turbos differ in that some vent the air directly oustide the whole system, or some vent the excess back in the system only in front of the turbo. either way, turbos either dont have wastegates, or they are acutated electronically.
TheUtubeEngineer 6 months ago
@TheUtubeEngineer Thanks for the explanation, recently I read some technical info on Garrett's turbo's website and with your explanation now I have a global perspective of turbos, ratios used and also compressors maps... looking forward to install a T28 on a nissan sentra lol
thanks again! nice video!

TheUtubeEngineer 6 months ago
@physicsguy91 very few turbos are actuated mechanically, but it is done by a piece of metal moved by the pressure differences

A cubic foot of air is a cubic foot. No matter what temperature. The colder the air the closer together the molecules, thus more dense. More dense means more oxygen, and more oxygen means more burn.

Hey man, one way or another people are gonna hate... whether or not your pressure numbers are completely accurate or not, your overall demonstration was both very informative and clear.

@miasmablk this is exactly why you need an intercooler

@miasmablk l2physics dumbass >.>
- Explosions need air; the more air, the more splosion you get.
- Cold air condenses, therefore more air in same amount of space
- Do the math
lambchop713 8 months ago
@miasmablk i dont know what you are talking about it may have more volume but ts less dense so basically in a cold cubic centimeter of air is actually ore air than a hot cubic centimeter of air... therefore you have more air within less space ...

An intercooler is really called a charged air cooler and not a radiator. also it can act as a restriction to the air pressure vs a gain... If the piping is too long or makes abrupt turns. Thats for a front mounted charged air cooler. a top mounted like seen on some models of Subarus etc.. have advantages and disanv. Adv. shorter distance air has to travel. Dis. Heat rises and engine heat onder the hood goes UP (around the "intercooler") therefor decreasing efficiency.. little things to consider
ebu1mp 11 months ago
Not to hate.. But dude your explanation and knowledge is NOT necessarily acurate. Your throwing around numbers that dont pertain to any old turbo charger. 35+15 PSI=50 PSI of boost!! ... If you had 50 PSI of boost you would blow your engine within ten seconds. I've seen a ford focus engine block explode on the dynomometer with 25. With those numbers you better have a fully tuned performance head, valve train, header. intake manifold, Ported E and I on head, 3-5 angle seat matching. . . . .
ebu1mp 11 months ago
@ebu1mp yes, forgive me if i did not specify that this was for DIESEL engines, obviously that run at compression ratios far beyond gasoline, and can easily handle 50 psi of boost.
