>tfw you realise RPM refers to engine revolutions and not wheel revolutions
Y-you didn't know?
>>14746453
My whole life I thought it referred to how many times your wheels were spinning every minute and always was amazed that the wheels were going that fast because they didn't look like they were
How did you not know that?
>>14746448
your speedometer does that dipshit
>>14746463
Idk, I guess >Peruvian education
Nigga wtf
Like how? You change gears and the car stays the same speed, but your rpm decreases.
Nigga literally how
>>14746448
> automatic drivers
Wow someone who definetly doesn't belong on /o/
>>14746510
I drive a manual I just never look at the rpm, I go off of sound
>>14746448
kek. hey, at some point each and everyone of us on /o/ didnt know what RPM referred to. learn something new every day
I'm lafffin right now. It measures the revolutions of the flywheel dumbass. that's why revs go down when you change to a higher gear, even though you are going faster.
>1st gear shift at 2krpm to 2nd
>rpm drops to 1500rpm but speed increases
>????
the mind of OP
>>14746448
>RPM
>Wheel speed
>It makes total sense that wheel speed drops anywhere from 800 to 200 RPM between gears with no loss in traction
>>14746448
At least you knew it was revolutions and not rotations
>>14746448
>tfw your wheels are rotating over 100 times per second
Nigga you idle around 800 rpm. Standing still.
How dumb are you?

I'd say he fits, this board's a fucking cesspool of circlejerked misinformation
>>14746448
It's ok, bro. We're all gonna make it someday.
>>14746448
if you're using a 1:1 overdrive, it does
>>14746531
i'm pretty sure anyone who is half decent at manual does that
>>14746676
Exactly what I thought
Kek
>>14746754
If the gear ratio's 1:1 it's not overdrive is it, twatfeatures
>>14746781
samedrive then, m8
>>14746754
Except for the diff ratio uleh
>>14746754
>1:1
>Overdrive.
>>14746531
Yes but you still understand the idea of rpm not always being directly connected to the tires. That's almost a requirement of proper manual driving. The only way OP can happen is if he "drives" an automatic.
>>14746754
I believe you have shit in lieu of a brain.
>>14746448
>TFW you realize OP is a faggot and a retard.
Isn't the speedometer technically the wheel tachometer
>>14747282
No.
>>14746448
>op going 30mph in 1st gear
WOW deez tires spinnin 7 thousand times!
>>14747347
Your speed is calculated via the rpm of the wheel though
>>14746462
Shiiieeeet
>>14747264
lmfao top kek
>>14747394
Ugh no it's not...
Speed sensor in transmission....
>>14747450
Lol the fuck. Explain to me how your speedometer reads incorrectly when you get a smaller or bigger wheel and tire diameter than stock.
>>14747476
>>14747450
>>14747476
Lolwat. just stop.
>>14747476
There's a speed sensor in the transmission
>>14747476
Really senpai? Just use your brain. Wheels are connected to drive shaft, drive shaft is connected to transmission.
If you make the wheels larger, the drive shaft spins slower, drive shaft spins slower, the transmission spins slower.

uwot faggots
>>14747476
you're right
>>14746448
dogumi you know nothing about cars
omg you such a dumb fuck
*veers into a truck*
You're no exception OP
>>14747476
Because 1 wheel revolution will be a different distance than the sensor is calibrated for at any given speed. Which is why bigger wheels/tires means your speedometer is reading slightly low at highway speed compared to actual
>>14747499
Pretty sure it's on the differential.
>>14749244
its in the transmission.
this is like a month worth of retardation in one thread
>>14746448
How is that not obvious.
If that were the case, every time you spun your wheels your RPM needle would spin round, fly off, and hit you in your stupid fucking face

>6000rpm
>wheel has a rolling length of 1.8m per revolution
>10800m per minute
>10800 / 60 = 180 = 180m per second
>180 x 3600 = 648 000 = 648 000 meters per hour
>648 000 / 1000 = 684 = 684kph
So if my math is correct, at 6000RPM an average car should do 684kph, or 425mph
>>14750736

>not owning a 4 banger FWD that can do 425mph
git gud namefag
>>14746448
tfw i know someone with a manual truck with no rpm gauge
OP have you ever revved your car and noticed the little dial on the dash shoot up the number range? You're telling me it never clicked in your head that when that dial went up you didn't launch forward?
Bullshit.
7/10 thread
>>14750736
you forgot gear ratios at 6 grand with a lower than 1:1 transmision ratio and a 3.watever rearend ratio should be doing in the neighborhood of 100mph
>>14746676
>he isnt doing a constant burnout
