Hey guys, so I've been searching for something but I can't find what I'm looking for.
What is the difference between single, twin, triple, and quad turbo, and how do each of them work? I've only been getting results about which setup works best for certain engines, but that's not what i want.
Thanks.
Single is one turbo. Twin is two turbos. Triple is three turbos. Quad is four turbos. Each of them pretty much work the same, it's just different duct work for the air. One side of the turbo impeller is driven by exhaust gas escaping from the combustion cycle. This turns it. The other side of the impeller pulls air in for the intake, thus forced air induction.
A turbo basically shoots more air into the cylinders than a naturally aspirated (no turbo/supercharger) engine. As Rubber said, exhaust gasses spin the impeller, which draws in air, it goes through the turbo and through an intercooler where the air is cooled, it then goes into the throttle body and into the engine. Colder air=more air, as you know heat expands, so theres the same volume but it isn't as compressed, also the reason why for turbo setups that are stock N/A (naturally aspirated) need a tune, because the map sensor goes crazy (manifold absolute pressure) since it has way more air coming in. you get more turbos, more air, more power. the downfall of turbos is that they're for high end power, if the engine is idling theres not much exhaust gas being produced, but once you get up to 5000-6000 rpm (vtec yo) you're getting a lot more exhaust gas, so it makes the turbo spin faster, or "spool". This is the short version, I could go on describing superchargers (same use but belt driven instead of exhaust gasses) wastegates, blowoff valves (dat noise tho) and turbo sizes :P
Oh and the other downfall, too much air pressure=head gasket/engine goes boom (goes for turbo and supercharger)
now you understand ?

I'd kind of like to know the rest too <3

pretty much explains it all
More turbos configured in parallel increases low-end power and reduces the effects of turbo lag (smaller turbos are easier to spin up). A V6 for example could have a turbo for each bank of cylinders (turbo 1 for first 3 cylinders on bank 1, turbo 2 for the rest).

Or can be installed 2 different sized turbos for different RPM ranges.. Or just have like you said, 1 turbo for each bank of cylinders (in V engines) (I have intresting configurtion said way in my truck, first kicks in at about 1100-1700rpm and second after 1600-2000) Never seen 3 or 4 turbos in same car.. And infact its inpractical because really no V8 or Straight 6 can spin the turbos unless they are really small. Unless they are some über racing engines

I had 2 44mm turbo chargers on my truck and it was 3.5 v6, also, the Bugatti EB110 has 4 turbos and it's also a 3.5 :v
I believe diesels use triple turbo (well they do if you can set them up like that) because i've seen vids of them in action

Diesels use twin turbo at max.. 3 is just useless already. Think about it.. Whats a point in 3.. Because turbos are not "TURBO = + 200hp, 2x TURBO = + 400hp" No.. Just No. You get to a point where the engine may not handle the amount of compression of the air. Nor run because of it
And who the hell would want a car that can empty it's fuel tank in 12 minutes?
I had 6 cylinders and it was 16 litre engine. (word
truck should not mean those pathetic american pickups)

Thats a veyron, not an EB110
But yea I've seen engines blow up a few times because the turbo made too much compression, although I still want to have the most complex and detailed explanation you guys can give me :)

I don't know what else to call it, in South Africa we call them bakkies, you would maybe not know what bakkie means, so I used a word everyone is familiar with(why does everyone go ape shit about that)
Want to watch some pretty cool videos? Youtube runaway diesel. Happens when tubo seal fails and oil is sprayed into the intake. Engine goes full throttle and nothing you can do to shut it off. Only way to kill it is by cutting off air supply to the turbo.

I remember seeing this video on reddit;
You can try stalling the engine by engaging highest gear, or try jamming a towel/some clothing in the air intake ASAP.
What happened here though is the coolant got too hot and popped something, and the engine seized up. I seriously would not want to be the owner of that car at that moment...
