  • 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
