1
00:00:52,344 --> 00:00:54,344
Narrator:
Caviar is made
2
00:00:54,344 --> 00:00:58,586
By processing the unfertilized
Eggs of certain species of fish.
3
00:00:58,586 --> 00:01:01,655
For those who love the taste
But not the price,
4
00:01:01,655 --> 00:01:05,206
There's simulated caviar
Made of kelp, a type of seaweed.
5
00:01:05,206 --> 00:01:07,172
A fraction of the cost,
6
00:01:07,172 --> 00:01:11,034
It looks, smells, and tastes
Similar to the real thing.
7
00:01:15,172 --> 00:01:19,172
Unlike fish caviar, the source
Of kelp caviar is a plant,
8
00:01:19,172 --> 00:01:21,827
So it's fat-free,
Cholesterol-free,
9
00:01:21,827 --> 00:01:24,275
And has zero calories.
10
00:01:24,275 --> 00:01:27,310
This company makes
Its kelp caviar plain,
11
00:01:27,310 --> 00:01:28,827
Which is vegetarian,
12
00:01:28,827 --> 00:01:31,000
As well as in several flavors.
13
00:01:31,000 --> 00:01:34,137
Kelp is chock-full of vitamins
And minerals
14
00:01:34,137 --> 00:01:37,344
And is especially rich
In iodine.
15
00:01:37,344 --> 00:01:41,137
Being a marine plant, it's quite
Different from land plants
16
00:01:41,137 --> 00:01:43,793
In that its consistency
Is gelatinous,
17
00:01:43,793 --> 00:01:46,931
Which makes it ideal for
Producing little rubbery balls
18
00:01:46,931 --> 00:01:48,896
That resemble fish eggs.
19
00:01:50,724 --> 00:01:52,517
At the kelp caviar factory,
20
00:01:52,517 --> 00:01:56,344
They begin production with kelp
That's been dried naturally,
21
00:01:56,344 --> 00:01:58,620
Then ground into a fine powder.
22
00:02:02,448 --> 00:02:06,413
The other ingredients are salt,
Citric acid,
23
00:02:06,413 --> 00:02:08,689
And, if they're making
A flavored variety,
24
00:02:08,689 --> 00:02:11,275
Natural flavoring
In liquid form.
25
00:02:15,482 --> 00:02:18,655
They add the ingredients
One at a time to water.
26
00:02:29,620 --> 00:02:32,586
The mixer blends them thoroughly
For about an hour,
27
00:02:32,586 --> 00:02:35,241
Producing
A thick, gelatinous liquid.
28
00:02:37,482 --> 00:02:39,413
They transfer the mixture
Into a pot
29
00:02:39,413 --> 00:02:41,275
Connected
To an extrusion machine.
30
00:02:51,724 --> 00:02:53,896
The machine pumps the mixture
31
00:02:53,896 --> 00:02:56,827
Through what looks
Like a showerhead,
32
00:02:56,827 --> 00:02:59,310
Only instead of outputting
A steady stream,
33
00:02:59,310 --> 00:03:01,310
It squeezes out droplets,
34
00:03:01,310 --> 00:03:04,448
Producing tiny kelp balls
Called pearls,
35
00:03:04,448 --> 00:03:07,103
Which look
Exactly like fish eggs.
36
00:03:08,448 --> 00:03:12,344
The pearls drop into
A coagulation solution.
37
00:03:12,344 --> 00:03:14,724
Besides providing
A soft landing,
38
00:03:14,724 --> 00:03:17,689
This solution helps
Hold the pearls' shape.
39
00:03:27,379 --> 00:03:30,758
The pearls roll down a chute
Into waiting containers.
40
00:03:32,103 --> 00:03:34,413
The water drains out the bottom.
41
00:03:42,275 --> 00:03:45,413
Workers empty the containers
Into large colanders.
42
00:03:50,172 --> 00:03:52,896
Then they rinse
And strain the pearls
43
00:03:52,896 --> 00:03:55,862
To ensure they're all
A certain minimum size.
44
00:03:55,862 --> 00:03:57,379
Pearls that are too small
45
00:03:57,379 --> 00:03:59,896
Simply fall
Through the colander's holes.
46
00:03:59,896 --> 00:04:02,551
They weigh out
A specific quantity
47
00:04:02,551 --> 00:04:05,275
And mix in
An all-natural stabilizer
48
00:04:05,275 --> 00:04:09,551
Required to maintain the pearls'
Texture and round shape.
49
00:04:16,551 --> 00:04:18,827
The factory's
Quality-control lab
50
00:04:18,827 --> 00:04:20,724
Tests a sample from the batch
51
00:04:20,724 --> 00:04:23,379
To make sure the ph level
Is just right.
52
00:04:23,379 --> 00:04:27,241
Careful ph control,
Coupled with pasteurization,
53
00:04:27,241 --> 00:04:30,344
Is why this product doesn't
Require any preservatives.
54
00:04:32,206 --> 00:04:35,931
At the packaging station,
Workers fill glass jars,
55
00:04:35,931 --> 00:04:38,379
Then twist a tin lid
Onto each one.
56
00:04:39,896 --> 00:04:42,965
Then the jars go into
A pasteurization machine.
57
00:04:42,965 --> 00:04:45,724
It heats the caviar
To a high temperature
58
00:04:45,724 --> 00:04:48,034
For a specific period of time,
59
00:04:48,034 --> 00:04:50,172
Which kills off any bacteria.
60
00:04:50,172 --> 00:04:54,172
This ensures a two-year shelf
Life without refrigeration.
61
00:04:54,172 --> 00:04:57,793
Once opened, the product
Stays fresh in the fridge
62
00:04:57,793 --> 00:04:59,413
For three months.
63
00:04:59,413 --> 00:05:03,068
After printing each lid
With a lot number
64
00:05:03,068 --> 00:05:04,931
For tracking purposes,
65
00:05:04,931 --> 00:05:08,103
All that's left to do is dress
The jar in a cardboard label.
66
00:05:14,310 --> 00:05:18,310
Kelp caviar contains no
Artificial colors or flavors.
67
00:05:18,310 --> 00:05:20,655
Unlike certain types of caviar,
68
00:05:20,655 --> 00:05:23,517
It doesn't bleed color
To the surrounding food,
69
00:05:23,517 --> 00:05:25,000
Even when baked.
70
00:05:27,655 --> 00:05:29,172
And while real caviar
71
00:05:29,172 --> 00:05:32,827
Is typically either black
Sturgeon roe or red salmon roe,
72
00:05:32,827 --> 00:05:36,068
Kelp caviar comes
In additional flavors,
73
00:05:36,068 --> 00:05:39,965
Such as truffle, cognac,
And wasabi.
74
00:05:52,206 --> 00:05:55,310
Narrator: luxury sailboats
Evoke thoughts of freedom
75
00:05:55,310 --> 00:05:57,000
And sunsets on the ocean,
76
00:05:57,000 --> 00:06:00,000
But in the factory,
It's all about hard work,
77
00:06:00,000 --> 00:06:03,448
Because luxury sailboats
Are still mostly made by hand.
78
00:06:03,448 --> 00:06:06,517
Just a few hundred units
Are produced every year,
79
00:06:06,517 --> 00:06:10,310
Each boat requiring
Up to 3,000 hours of work.
80
00:06:15,206 --> 00:06:17,172
Sailboats have come a long way
81
00:06:17,172 --> 00:06:19,482
Since they were first used
On the nile river
82
00:06:19,482 --> 00:06:21,620
Some 6,000 years ago.
83
00:06:24,620 --> 00:06:26,862
These luxury sailboats
Are designed
84
00:06:26,862 --> 00:06:29,206
Using computer-aided
Design software,
85
00:06:29,206 --> 00:06:32,517
Which allows the engineers
To optimize the hull shape
86
00:06:32,517 --> 00:06:34,000
For stability and speed
87
00:06:34,000 --> 00:06:36,482
Before actually
Building the boat.
88
00:06:36,482 --> 00:06:39,379
They build the hull
From fiberglass,
89
00:06:39,379 --> 00:06:41,586
Which comes as knitted fabric
90
00:06:41,586 --> 00:06:45,379
And as mats of random strands
Pressed together.
91
00:06:45,379 --> 00:06:47,862
These two layers are hybridized
92
00:06:47,862 --> 00:06:51,827
To form a light
But very strong material.
93
00:06:51,827 --> 00:06:56,482
Huge molds are used to build
The hull of this 45-foot boat.
94
00:06:56,482 --> 00:07:00,724
Workers unroll the fiberglass
And spray it with resin.
95
00:07:02,655 --> 00:07:05,551
Then they unroll the next layer
Of fiberglass,
96
00:07:05,551 --> 00:07:07,517
Which overlaps the previous one,
97
00:07:07,517 --> 00:07:10,172
Making for a very strong
Construction.
98
00:07:12,034 --> 00:07:15,137
The resin hardens as it cures.
99
00:07:17,551 --> 00:07:19,931
Boat parts are so large
And heavy
100
00:07:19,931 --> 00:07:22,448
That they must be moved
With cranes.
101
00:07:22,448 --> 00:07:24,517
This part is called the transom.
102
00:07:24,517 --> 00:07:27,620
It will be attached to the hull
With fiberglass
103
00:07:27,620 --> 00:07:30,275
While it and the hull
Are still in the molds,
104
00:07:30,275 --> 00:07:32,965
Creating what's called
A monaco construction.
105
00:07:32,965 --> 00:07:35,862
This hull surface will receive
The structural grid,
106
00:07:35,862 --> 00:07:39,103
Which will support the engine,
Mast, fuel tank,
107
00:07:39,103 --> 00:07:41,068
And water tanks.
108
00:07:41,068 --> 00:07:44,758
Meanwhile, carpenters fashion
The wood components.
109
00:07:44,758 --> 00:07:46,931
This door is made of solid teak,
110
00:07:46,931 --> 00:07:50,482
A durable hardwood
That doesn't rot.
111
00:07:50,482 --> 00:07:52,862
The wood parts are then put
Into a curing oven
112
00:07:52,862 --> 00:07:55,413
At 122 degrees fahrenheit.
113
00:07:55,413 --> 00:07:58,689
Air is circulated to cure
The varnish in about 11 minutes.
114
00:08:00,896 --> 00:08:03,310
Bright lights also help
Cure the varnish.
115
00:08:05,206 --> 00:08:07,862
It's time to put the divisions
In place.
116
00:08:07,862 --> 00:08:09,482
The hull liner has slots
117
00:08:09,482 --> 00:08:13,827
Designed to receive
The various wood components.
118
00:08:13,827 --> 00:08:16,000
Each part is fitted twice --
119
00:08:16,000 --> 00:08:18,344
First to check the fit,
120
00:08:18,344 --> 00:08:20,862
Then permanently
With high-strength adhesive.
121
00:08:29,758 --> 00:08:32,172
It's time to install the engine.
122
00:08:32,172 --> 00:08:36,241
With its 54 horsepower,
The boat can cruise at 8 knots,
123
00:08:36,241 --> 00:08:38,137
Even when the wind
Isn't blowing.
124
00:08:41,620 --> 00:08:46,172
This stainless-steel structure
Serves to reinforce the rudder.
125
00:08:46,172 --> 00:08:48,620
It's attached with epoxy glue.
126
00:08:54,655 --> 00:08:58,413
After closing the rudder mold,
They insert a paper cone
127
00:08:58,413 --> 00:09:01,413
To completely fill the rudder
With urethane foam.
128
00:09:04,482 --> 00:09:07,689
The foam expands as it cures.
129
00:09:10,310 --> 00:09:13,862
They finish by carefully sanding
The edges of the rudder,
130
00:09:13,862 --> 00:09:16,758
Which is now attached
Underneath the hull.
131
00:09:23,620 --> 00:09:25,413
To build the boat's deck,
132
00:09:25,413 --> 00:09:29,000
Molds for the top and bottom
Parts must be aligned.
133
00:09:29,000 --> 00:09:33,379
High-strength bonding material
Is applied at specific spots.
134
00:09:36,103 --> 00:09:39,000
The two molds are
Carefully fitted together.
135
00:09:43,413 --> 00:09:47,379
When the parts are perfectly
Joined, the mold is removed.
136
00:09:48,862 --> 00:09:51,482
The deck is now ready
To be fitted on the boat.
137
00:09:59,241 --> 00:10:02,413
Workers carefully line
Everything up.
138
00:10:09,137 --> 00:10:12,862
Luxury sailboats have
Enough space for many rooms
139
00:10:12,862 --> 00:10:16,862
And can be customized
With appliances and electronics
140
00:10:16,862 --> 00:10:20,103
That suit the customer's needs
And tastes.
141
00:10:20,103 --> 00:10:23,896
All that's needed now
Is a dip in the test pool
142
00:10:23,896 --> 00:10:26,103
For a check of the engine,
Generator,
143
00:10:26,103 --> 00:10:28,413
And other mechanical systems.
144
00:10:31,310 --> 00:10:33,344
After about three months
Of hard work,
145
00:10:33,344 --> 00:10:37,931
The boat is now ready to set
Sail for offshore adventures.
146
00:10:52,344 --> 00:10:55,103
Narrator: dental work dates back
To ancient egypt,
147
00:10:55,103 --> 00:10:57,724
When people used animal teeth
And pieces of bone
148
00:10:57,724 --> 00:10:59,448
To replace their own teeth.
149
00:10:59,448 --> 00:11:01,379
It couldn't have been pretty,
150
00:11:01,379 --> 00:11:03,758
But today,
High-tech dental crowns
151
00:11:03,758 --> 00:11:06,758
Can transform damaged teeth
Into pearly whites
152
00:11:06,758 --> 00:11:09,413
That look
Just like all the rest.
153
00:11:13,793 --> 00:11:18,137
A dental crown starts with a
Plaster impression of the mouth.
154
00:11:20,862 --> 00:11:24,586
It goes to a laboratory,
Where they cut it into segments
155
00:11:24,586 --> 00:11:27,896
To isolate the tooth
In need of restoration.
156
00:11:27,896 --> 00:11:30,655
They scan it into a computer
157
00:11:30,655 --> 00:11:34,000
And send the dimensions
Electronically to the factory.
158
00:11:36,344 --> 00:11:40,103
There, machinery pumps
Liquid plaster into molds
159
00:11:40,103 --> 00:11:42,931
To create cylinders
Called blanks.
160
00:11:42,931 --> 00:11:46,862
The plaster blanks take
About 10 minutes to harden,
161
00:11:46,862 --> 00:11:50,379
Then move on to cure
For an additional 12 hours.
162
00:11:54,206 --> 00:11:55,655
At the next station,
163
00:11:55,655 --> 00:11:58,827
A robot installs a blank
In a milling machine.
164
00:11:58,827 --> 00:12:02,379
A computerized cutting tool
Sculpts the blank,
165
00:12:02,379 --> 00:12:05,172
Guided by the scanned data
Of the plaster replica.
166
00:12:06,724 --> 00:12:10,206
It makes a duplicate
That's 20% to 30% larger
167
00:12:10,206 --> 00:12:13,275
To allow for material shrinkage
Later in production.
168
00:12:22,517 --> 00:12:27,034
Next, a device dips the plaster
Tooth in liquid ceramic,
169
00:12:27,034 --> 00:12:30,000
Which hardens
Into a nonstick glaze.
170
00:12:35,344 --> 00:12:37,137
The next robot
Orients the tooth,
171
00:12:37,137 --> 00:12:38,482
Along with several others,
172
00:12:38,482 --> 00:12:40,620
In a circular holder,
173
00:12:40,620 --> 00:12:43,034
Ready for the next phase
Of production.
174
00:12:44,896 --> 00:12:47,965
Nozzles funnel ceramic powder
Into molds
175
00:12:47,965 --> 00:12:51,379
Arranged in a matching
Circular configuration.
176
00:12:54,068 --> 00:12:56,758
A robot then inserts
The tooth replicas
177
00:12:56,758 --> 00:12:59,000
In the corresponding molds.
178
00:13:01,482 --> 00:13:04,241
A worker stacks several
Of the mold platters
179
00:13:04,241 --> 00:13:07,310
And threads them together
With a metal rod.
180
00:13:07,310 --> 00:13:11,206
He transfers the rack of mold
Platters to the next worker,
181
00:13:11,206 --> 00:13:14,344
Who plunges it into
A water-filled chamber.
182
00:13:16,344 --> 00:13:20,620
He closes the lid and activates
A pressurizing system.
183
00:13:20,620 --> 00:13:22,724
As the liquid pressurizes,
184
00:13:22,724 --> 00:13:26,448
It compresses the ceramic
Powder, solidifying it.
185
00:13:26,448 --> 00:13:29,965
This process
Takes just 10 minutes.
186
00:13:29,965 --> 00:13:34,103
Another automated tool now
Chisels away the excess ceramic,
187
00:13:34,103 --> 00:13:37,655
Following the profile
Of the plaster tooth replica
188
00:13:37,655 --> 00:13:39,724
That's still inside.
189
00:13:39,724 --> 00:13:42,689
This creates the ceramic shell
Of the dental crown,
190
00:13:42,689 --> 00:13:45,068
Called the coping.
191
00:13:45,068 --> 00:13:47,586
It's removed
From the plaster replica,
192
00:13:47,586 --> 00:13:50,000
Thanks to the nonstick glaze.
193
00:13:51,517 --> 00:13:54,172
Baking the coping
At a very high temperature
194
00:13:54,172 --> 00:13:56,034
Toughens the ceramic.
195
00:13:56,034 --> 00:13:59,448
It also shrinks the crown shell
To the final size.
196
00:14:01,310 --> 00:14:03,620
They carve a plastic copy
Of the tooth,
197
00:14:03,620 --> 00:14:08,206
Using the same data scanned
Into the computer earlier.
198
00:14:08,206 --> 00:14:12,689
They use this plastic replica to
Test the fit of the ceramic one.
199
00:14:15,793 --> 00:14:19,689
A technician inspects
The ceramic for chips or cracks,
200
00:14:19,689 --> 00:14:22,275
Then packages it for shipping.
201
00:14:25,379 --> 00:14:29,137
This tooth-like shell is now
On its way to the laboratory,
202
00:14:29,137 --> 00:14:31,137
Where it will get
The finishing touches
203
00:14:31,137 --> 00:14:33,965
That will transform it
Into a crown.
204
00:14:36,758 --> 00:14:38,827
When it arrives at the lab,
205
00:14:38,827 --> 00:14:42,068
A technician paints several
Layers of porcelain onto it.
206
00:14:43,827 --> 00:14:46,758
The color will change
To a more-realistic hue
207
00:14:46,758 --> 00:14:49,448
Once they fire it
In a special furnace.
208
00:14:57,068 --> 00:14:59,793
The furnace pumps out air
Or other gases
209
00:14:59,793 --> 00:15:02,206
That would hinder the transfer
Of heat
210
00:15:02,206 --> 00:15:05,310
As it bakes the porcelain
To a very dense consistency.
211
00:15:07,551 --> 00:15:10,758
After all the layers
Have been applied,
212
00:15:10,758 --> 00:15:14,275
A technician textures
The surface with a sharp tool.
213
00:15:14,275 --> 00:15:18,862
Then, she sculpts it
To give it tooth-like contours.
214
00:15:18,862 --> 00:15:22,689
Finally, she brushes on
A clear ceramic glaze,
215
00:15:22,689 --> 00:15:26,103
Which mimics the look
Of tooth enamel.
216
00:15:26,103 --> 00:15:29,827
Ceramic crowns like these
Take about five days to make.
217
00:15:29,827 --> 00:15:33,379
They'll look and function
Just like any other tooth,
218
00:15:33,379 --> 00:15:36,103
And no one
Need ever know the secret
219
00:15:36,103 --> 00:15:38,034
Behind that beautiful smile.
220
00:15:49,000 --> 00:15:50,965
Narrator:
High-performance engines
221
00:15:50,965 --> 00:15:52,551
Are technology-packed marvels
222
00:15:52,551 --> 00:15:54,758
That are the result
Of exacting design,
223
00:15:54,758 --> 00:15:57,793
Modern engineering, and
A constant need for innovation.
224
00:15:57,793 --> 00:15:59,827
Producing them
Requires the skills
225
00:15:59,827 --> 00:16:01,896
Of many highly trained
Technicians.
226
00:16:01,896 --> 00:16:04,862
It's the lucky few that will
Get to enjoy the performance
227
00:16:04,862 --> 00:16:07,965
And thrills
These engines can provide.
228
00:16:12,241 --> 00:16:14,965
Under the hood of this car
Is the latest
229
00:16:14,965 --> 00:16:17,517
In a long line
Of performance engines,
230
00:16:17,517 --> 00:16:20,551
Legendary as much
For their power as their looks.
231
00:16:23,896 --> 00:16:27,275
Each generation of engine
Delivers an increase in power
232
00:16:27,275 --> 00:16:28,931
And a reduction in weight,
233
00:16:28,931 --> 00:16:33,482
Meaning today's engines consume
Less fuel and produce less co2.
234
00:16:35,275 --> 00:16:38,793
At the heart of every engine
Is the engine block.
235
00:16:38,793 --> 00:16:40,827
It begins with a set of molds
236
00:16:40,827 --> 00:16:44,344
Cast from a mixture
Of special sand and resin.
237
00:16:44,344 --> 00:16:47,724
Technicians glue the mold parts
Together.
238
00:16:50,068 --> 00:16:53,103
Using a hand file,
They make final adjustments
239
00:16:53,103 --> 00:16:57,137
By sculpting the sand mold down
To the finest detail.
240
00:16:57,137 --> 00:17:01,103
An automated machine releases
Molten aluminum into the mold.
241
00:17:06,413 --> 00:17:08,034
After a cooling period,
242
00:17:08,034 --> 00:17:11,000
The machine releases the part
From the mold.
243
00:17:16,448 --> 00:17:18,931
They must remove
All of the sand,
244
00:17:18,931 --> 00:17:22,310
Which formed the hollow spaces
Inside the engine.
245
00:17:26,482 --> 00:17:28,655
They spray-wash
The cylinder head
246
00:17:28,655 --> 00:17:30,965
To clear away
Any remaining debris.
247
00:17:34,172 --> 00:17:37,896
Technicians now begin to
Pre-assemble the cylinder head
248
00:17:37,896 --> 00:17:39,862
And intake manifold.
249
00:17:41,793 --> 00:17:44,689
Every part of the engine,
Such as this cylinder head,
250
00:17:44,689 --> 00:17:46,310
Is made from aluminum --
251
00:17:46,310 --> 00:17:49,517
Expensive but lightweight.
252
00:17:54,344 --> 00:17:58,413
Here, robots immerse
Valve guides in liquid hydrogen.
253
00:17:59,965 --> 00:18:01,793
This causes them to contract
254
00:18:01,793 --> 00:18:05,275
So they can be easily inserted
Into the cylinder heads.
255
00:18:07,275 --> 00:18:11,034
As the valve guides warm up,
They expand slightly,
256
00:18:11,034 --> 00:18:13,137
Which holds them in place
Permanently.
257
00:18:15,655 --> 00:18:18,793
One set of valves
Lets fuel into the cylinder.
258
00:18:18,793 --> 00:18:21,275
The other lets exhaust out.
259
00:18:21,275 --> 00:18:23,551
With a blast of pressurized air,
260
00:18:23,551 --> 00:18:27,379
Workers verify that the
Manifold's air-intake passages
261
00:18:27,379 --> 00:18:29,137
Have been properly formed.
262
00:18:31,034 --> 00:18:33,241
Using a specially made tool,
263
00:18:33,241 --> 00:18:36,931
They verify the exact dimension
Of each valve.
264
00:18:39,310 --> 00:18:42,517
They visually inspect
Each cylinder head for debris
265
00:18:42,517 --> 00:18:44,172
And minor faults.
266
00:18:48,448 --> 00:18:52,241
If it passes, a worker tags it
With an I.D. Plate.
267
00:18:54,344 --> 00:18:58,655
Here technicians insert
The valves into position,
268
00:18:58,655 --> 00:19:00,965
Then test their movement.
269
00:19:02,931 --> 00:19:05,310
Next,
They machine the crankshaft
270
00:19:05,310 --> 00:19:07,758
Down to its final
Specifications,
271
00:19:07,758 --> 00:19:11,172
And the entire assembly is
Positioned in the engine block.
272
00:19:14,862 --> 00:19:18,586
A technician lubricates
The cylinder liners...
273
00:19:21,620 --> 00:19:24,275
...Then inserts them
Into the cylinders.
274
00:19:27,068 --> 00:19:31,137
They tap the liners into
Position with a rubber mallet.
275
00:19:31,137 --> 00:19:33,965
Then, using a bit of lubricant,
276
00:19:33,965 --> 00:19:36,724
They insert the pistons
And connecting rods
277
00:19:36,724 --> 00:19:38,931
Into each cylinder.
278
00:19:45,862 --> 00:19:48,482
With the aid
Of an automatic torque gun,
279
00:19:48,482 --> 00:19:50,448
Technicians secure
The connecting rods
280
00:19:50,448 --> 00:19:51,931
To the crankshaft,
281
00:19:51,931 --> 00:19:54,758
Then verify
The crankshaft spacing.
282
00:20:00,896 --> 00:20:05,000
Next, workers position
And bolt in the valve cover.
283
00:20:11,206 --> 00:20:13,965
Then they install
The air-intake manifold
284
00:20:13,965 --> 00:20:16,068
On top of the engine
285
00:20:16,068 --> 00:20:19,103
And attach
The fuel-injection system.
286
00:20:26,034 --> 00:20:27,965
They hook up the finished engine
287
00:20:27,965 --> 00:20:30,172
To a machine
Called a dynamometer,
288
00:20:30,172 --> 00:20:33,103
Which measures every aspect
Of engine performance
289
00:20:33,103 --> 00:20:35,103
Down to the smallest detail.
290
00:20:38,413 --> 00:20:42,137
And now for the ultimate test --
The road test.
