    In the world of car tuning, particularly regarding gearboxes in games like 'Cark Street,' it's crucial to consider the engine graph and wheel sizes before making adjustments. Each engine has a unique power graph that determines the optimal settings for the gearbox. The video explains that while second and third gears should start around 5,000 RPM for grip, higher gears should start around 6,000 RPM where the engine hits peak horsepower. This setting allows for a higher top speed and better performance. The video emphasizes the need for balance between torque and horsepower, especially in vehicles with different drive systems such as rear-wheel and all-wheel drive. Adjustments also depend on whether you've changed the engine or transmission, requiring test drives to determine if gear ratio settings need to be adjusted. Additionally, there's a focus on how wheel size affects the final drive ratio and performance, with tips for maximizing top speed and acceleration by balancing these factors. In summary, tuning a car's gearbox involves complex considerations but can significantly impact racing performance.

  • 00:00:01
    in cark Street you can't simply go to
  • 00:00:04
    the gearbox section and start tuning
  • 00:00:06
    before doing that you need to check your
  • 00:00:08
    engine graph and wheel sizes as these
  • 00:00:10
    two factors play a big role in setting
  • 00:00:12
    up your gearbox I know it might sound
  • 00:00:14
    complicated but I'll explain it in the
  • 00:00:16
    simplest way
  • 00:00:18
    possible let's understand a few Basics
  • 00:00:20
    the main purpose of a gearbox is to
  • 00:00:22
    control the power and speed output from
  • 00:00:24
    the engine to the wheels keep in mind
  • 00:00:27
    that each engine has its own unique
  • 00:00:29
    power G
  • 00:00:30
    and this video will focus on the
  • 00:00:32
    transmission not the engine the blue
  • 00:00:34
    graph represents engine torque while the
  • 00:00:36
    white graph shows horsepower according
  • 00:00:39
    to the power graph your second and third
  • 00:00:41
    gears should start around 5,000
  • 00:00:43
    revolutions per minute for better grip
  • 00:00:45
    during launch and when exiting
  • 00:00:47
    Corners however that's not where your
  • 00:00:50
    engine produces maximum horsepower
  • 00:00:52
    that's why your fourth fifth and six
  • 00:00:54
    gears should start around 6,000 RPM
  • 00:00:57
    where the engine produces Peak
  • 00:00:58
    horsepower allowing for for a higher top
  • 00:01:01
    speed as I mentioned earlier each engine
  • 00:01:04
    has a different Power graph so you need
  • 00:01:06
    to find the optimal points for the best
  • 00:01:08
    output from your gearbox by carefully
  • 00:01:10
    reading the power graph even though this
  • 00:01:12
    engine has great torque around 4,000 RPM
  • 00:01:16
    however the horsepower isn't quite
  • 00:01:18
    strong enough at that point I found it
  • 00:01:20
    works better to set the second gear to
  • 00:01:22
    start at around 5,000 RPM where torque
  • 00:01:24
    and horsepower are more
  • 00:01:27
    balanced here's some examples keep your
  • 00:01:29
    your eyes on the
  • 00:01:34
    [Music]
  • 00:01:46
    tachometer and as I just mentioned all
  • 00:01:49
    stock cars with stock engines and stock
  • 00:01:51
    transmissions already come with that
  • 00:01:53
    configuration from the factory this
  • 00:01:56
    means that as long as you haven't
  • 00:01:57
    swapped the engine or transmission you
  • 00:01:59
    don't need to adjust the gear boox you
  • 00:02:01
    can leave it as is or increase the ratio
  • 00:02:03
    for better power output however higher
  • 00:02:06
    ratios will require larger Wheels to
  • 00:02:08
    handle the increased power but if your
  • 00:02:10
    car is a rear wheeel drive you might
  • 00:02:12
    want to decrease the first gear ratio to
  • 00:02:14
    Balance power output but why all-wheel
  • 00:02:17
    drive and rear wheeel drive is different
  • 00:02:20
    all-wheel drive cars distribute power to
  • 00:02:22
    both the front and rear wheels while
  • 00:02:24
    rear wheeel drive cars only send power
  • 00:02:27
    to the drive Wheels this often results
  • 00:02:29
    in too much power on the rear tires
  • 00:02:32
    making them more prone to slipping
  • 00:02:34
    that's why it's important to balance the
  • 00:02:36
    power output now what if you swap the
  • 00:02:38
    engine or transmission first you need to
  • 00:02:41
    test drive the car and see how it
  • 00:02:43
    performs in most cases the Gear start at
  • 00:02:46
    5,000 revolutions per minute which seems
  • 00:02:48
    fine however after checking the power
  • 00:02:50
    graph of this car I realized it should
  • 00:02:53
    actually start at 5,500 revolutions per
  • 00:02:56
    minute so I went back to the tuning shop
  • 00:02:58
    and adjusted the gearbox you might have
  • 00:03:00
    noticed that the first gear ratio was
  • 00:03:02
    set to low setting the first gear ratio
  • 00:03:05
    to low can cause a slower
  • 00:03:07
    launch however it only feels slow with
  • 00:03:10
    regular gas actually I had tuned the
  • 00:03:13
    gearbox for Sport gas now let's see how
  • 00:03:16
    it performs with Sport
  • 00:03:20
    gas all right before we set the gears
  • 00:03:23
    let's see how to adjust the final drive
  • 00:03:25
    based on Wheel sizes you should use a
  • 00:03:27
    higher final drive ratio for better
  • 00:03:29
    acceleration in circuit racing and the
  • 00:03:32
    opposite for achieving higher top speed
  • 00:03:34
    however if you use the biggest rims and
  • 00:03:36
    the lowest first gear ratio but your
  • 00:03:38
    wheels are still slipping when launching
  • 00:03:40
    which normally happens in class 6 cars
  • 00:03:43
    you will need to decrease the final
  • 00:03:45
    drive ratio after you know all the
  • 00:03:47
    things that might affect your gearbox
  • 00:03:49
    set up you're now ready for gearbox
  • 00:03:51
    tuning let's take a look at first gear
  • 00:03:53
    you usually use first gear for launching
  • 00:03:56
    if your car is all-wheel drive you
  • 00:03:58
    should increase ratio but if your car is
  • 00:04:00
    not all-wheel drive you should try to
  • 00:04:02
    Balance power around the middle now take
  • 00:04:05
    a look at the second gear keep in mind
  • 00:04:07
    that you're now adjusting the gear ratio
  • 00:04:09
    the next gear you are about to set will
  • 00:04:11
    be heavily affected by previous gear as
  • 00:04:13
    I showed you earlier if it's lined up
  • 00:04:15
    the gear will start around 5,000 RPM if
  • 00:04:18
    you increase the second gear ratio it
  • 00:04:20
    will start with higher RPM but if you
  • 00:04:23
    decrease the second gear ratio it will
  • 00:04:26
    start with lower
  • 00:04:28
    RPM but if you you already increase the
  • 00:04:30
    first gear ratio to highest you won't be
  • 00:04:33
    able to increase the second gear ratio
  • 00:04:35
    and your second gear will start around
  • 00:04:37
    5,000 RPM you will only be able to
  • 00:04:40
    decrease second gear ratio so the only
  • 00:04:42
    way to increase the second gear ratio is
  • 00:04:45
    to decrease the first gear ratio this
  • 00:04:47
    also applies to the other gears for a
  • 00:04:50
    clearer picture here are some more
  • 00:04:52
    examples as well as I mentioned the next
  • 00:04:55
    gear you are about to set will be
  • 00:04:56
    heavily affected by previous gear
  • 00:05:00
    all right what about how I set up the
  • 00:05:02
    gearbox for my cars since you've already
  • 00:05:04
    seen my 40z and p91 gearboxes I'll show
  • 00:05:08
    you my m46 lmh and DX7 gearboxes however
  • 00:05:13
    my cars are used for circuit racing
  • 00:05:15
    which is why my final drive ratio is set
  • 00:05:17
    to the highest but what if you want to
  • 00:05:19
    do sprint races with a higher top speed
  • 00:05:22
    don't worry I've got some experiments
  • 00:05:24
    for you however I want to show you some
  • 00:05:26
    experiments on final drive ratios based
  • 00:05:28
    on Wheel sizes first the top speed final
  • 00:05:31
    drive ratio will come after that
  • 00:05:45
    [Music]
  • 00:06:07
    as you can see the 19-in wheel can
  • 00:06:10
    perform the same as the 22-in wheel if
  • 00:06:12
    you balance the final drive ratio with
  • 00:06:14
    the wheel size but there's something
  • 00:06:16
    interesting about the topspeed final
  • 00:06:18
    drive
  • 00:06:20
    setup a smaller Rim definitely provides
  • 00:06:23
    a faster launching speed but you'll be
  • 00:06:25
    surprised in the end
  • 00:06:33
    I thought the bigger Rim would hit 270
  • 00:06:36
    kmph first but it turns out the smaller
  • 00:06:39
    Rim is the winner maybe it's because my
  • 00:06:42
    car is classified as class
  • 00:06:48
    [Music]
  • 00:06:55
    3 in some cases a low final drive might
  • 00:06:58
    not always be the best for top speed the
  • 00:07:01
    only way to find out is to test
  • 00:07:05
    it however within the same class to
  • 00:07:08
    reach top speed you'll need more engine
  • 00:07:10
    power while a lighter weight is best for
  • 00:07:12
    better cornering and if you're going to
  • 00:07:14
    swap the transmission here's a quick
  • 00:07:19
    [Music]
  • 00:07:21
    guide for clutch and gearbox upgrades
  • 00:07:24
    just go for the ultimate Parts it's the
  • 00:07:26
    best choice however it's a bit different
  • 00:07:29
    for the differential the differential
  • 00:07:31
    can affect over steer and under steer
  • 00:07:33
    but don't worry I've already made a
  • 00:07:35
    video about it and if your engine graph
  • 00:07:37
    isn't showing just tap on any of
  • 00:07:40
    these there it
  • 00:07:42
    is you see setting up a gearbox isn't
  • 00:07:45
    that simple I hope this guide helps make
  • 00:07:47
    it easier for you it did take quite a
  • 00:07:49
    bit of time to make this video so I'd
  • 00:07:52
    really appreciate it if you could like
  • 00:07:53
    And subscribe all right I think that's
  • 00:07:56
    it for today thanks for watching see you
