How It's Made High-Performance Engines

[69KronoS69]

The liquid's nitrogen. It's - written - on the damn sign O_o' azoto=nitrogen

[lanmancz]

Really ? They use molds made by hand ? I thought these things were made by some precise cutting machines or something. But no, engine molds are made by hand. My mind is blown.

[dtxflores]

Time to build my own Ferrari.

[KrazeeCain]

How it's made is a decent show, but it could be so much better. I wish they would give extra time to features that deserve it, like this. 5 minutes to explain how they make pasta? fine. 5 minutes to explain the entire assembly process of a Ferrari engine? Hell no! For stuff like this, they need to dedicate the whole damn episode, and then some.

[knifemakejake]

they don't mention that all aluminum high performance parts are made from an aluminum alloy. aluminum buy itself is weak

[raven97990]

Those are not guides they are seats....

[xXCHICAGO71Xx]

The irony is that the workers don't have the salary to buy what they're making :/

[cgmp84]

@xXCHICAGO71Xx To my knowledge the pay is quite low. You are much better off building a Ford pickup truck.

[n3rdbear]

This is the first time I have ever seen an engine with two air intakes.

[xkambing]

are that workers have own sport car??

[ienjoyapples]

i started on pasta and this is about my 1,657th how its made video

[smacman68]

The idiots who make these have no idea what they're talking about. Error after error, and they skip most of the really interesting and difficult processes. They show you the minor crap. And the puns...enough to make a man shrudder.

[makexxx]

Damn nice looking combustion chambers!!

[steelmesh]

Worthless, may as well have shown an LS9 engine get assembled in the factory. If you title it High Performance, we should see them assemble a Pro-stock engine.

[U238Shell]

I don't understand how these engines produce less power than what some people do in a garage? Or are these engines just hugely more reliable then something like a 2JZ with a huge turbo whacked onto it?

[TheDustikus]

@U238Shell Only so much performance can be achieved with the reliability that the factory has to offer due to their warranty. And on top of that, once you "whack" a turbo on something, the power gains go through the roof, super or turbo charged, forced induction is where your big power is going to be, at least for a relatively small displacement engine. (Larger too of course, but you get the point....)

[kekkokekko89]

Ferrari rules!

[djfantom205]

Wow. It's surprisingly easy how engines are constructed nowadays.

[youtubasoarus]

2:10 - Those are valve seats, not guides.

[goodkill1]

"Every part of this engine such as this cylinder head is aluminum" Bullshit, the crank has to be steel, nothing spins as well as steel. The connecting rods might be carbon fiber and the valves titanium. Only the block and head are aluminum. There are so many things wrong with the commentary in this video you can't explain it with the character limit.

[ckelley63]

@goodkill1 Really, have yet to see any engine with a carbon fiber connecting rod.

[iGaveen]

@MrKadden Check again that it is for sure the Discovery Channel..

[ermollejuo]

best porn ever

[RacerEckss]

Even before watching, I knew there wouldnt be anything from Chevrolet....

[Achilles122100]

wow thats fucking awesome!

[UKRAINERULES253]

didnt even mention timing belts spark plugs camshaft

[flynniz]

not even a mention of camshafts :s ??

[Grousuba]

what happened to machining?

[YoungJim409]

@Grousuba At a guess most of it happens in machining cells under coolant, so they skipped it.

[tartupets]

@Grousuba machining produces micro fractures that are more common, than cast defects. Casting, high pressure casting in racing engines, produces a less stressed and less defected engine parts. And high performance engines need to have little stress in them to sustain the forces of pressure and torque.

[cyan933]

@Grousuba im pretty sure that the parts are machined , but they didn't have time to show all the individual parts so they only showed the actual engine block being molded out of aluminum

[Zealix]

@Grousuba No machining, just very, VERY careful casting.

[MrKaddan]

You'd think that the Discovery channel would know better than to call a liquid

-196.4 C liquid HYDROGEN? It's NITROGEN damnit!

[TehRamenBrotherz]

@MrKaddan its not nitrogen as nitrogen boils at -195.8 and normal temp is -210, and since liquid oxygen is colder its therefore most likely hydrogen

[MrKaddan]

@TehRamenBrotherz not true

[superdau]

@TehRamenBrotherz

What is a "normal temp"? Who's talking about oxygen? Hydrogen boils at 20K, which is way below -196°C. And btw: open gaseous hydrogen and electricity/industrial environment: good idea!!

So if nitrogen boils at -195,8°C and the sign says -196°C, what could be in the tank?

[Serostern]

@MrKaddan You are indeed correct. Azoto == Nitrogen.

But hydrogen is also liquid at -196, it freezes at -259.

[superdau]

@Serostern

Where do people all get these wrong numbers from? Last time i looked, Hydrogen boiled at 20 K or -252°C.

[madisonelectronic]

@MrKaddan Du hast geweih.

[mysock351W]

@MrKaddan Oh, theres a lot more than that. In that segment, those wherent valve guides, they where valve SEATS. And, they wherent testing the intake manifold passages with air, they where testing the cylinder head COOLANT passages.

[Slashbag69]

@MrKaddan Yeah, the factory would get blown into space if that was liquid hydrogen.

[JlkJlk18000]

@MrKaddan no its liquid Hydrogen... and its not the discovery channel its the science channel

[csmybuttt]

@JlkJlk18000

1. You're replying to a comment made a year ago.

2. You are downright wrong, so why are you correcting someone who is right?

I really hope you're a troll, because it's rather disheartening otherwise.

[TrevorHeath]

One would think the narrator, speaking with such authority would know the difference between a valve seat and a valve guide.....

Those sure look like a version of the Singh groove in the combustion chamber too

I wonder why the narrator does not mention them.....

[airr916]

lol, best one I ever seen so far....
