- In this video, I tell you everything that there is to know about the tachometer on a car. You will find a tachometer on the dashboard of most cars, and it serves a big purpose with regards to telling you what is going on with the car while you are driving. The most interesting thing about it is that many people don't actually know how to read a car tachometer and don't fully understand what it means. I made this video to clear that up and educate drivers about their car's tachometer.

I didn't know Jack septiceye did DIY car videos
Ll
That's mad funny🤣🤣🤣
I didn't hear it til I read this but omg I can't u hear it now
Wow, I have always been interested in what a tachometer really was for in vehicles, and I knew that it was for rpm. I knew what the red was for too, and the x1,000r was for also. Basically, I like numbers. I always appreciate when someone describes in everything in detail about vehicles and how they work because seriously, there might be someone that is curious about how a part of a vehicle works.
That makes so much more sense thx I’m trying to learn more abt cars because I can drive now
❤❤❤p❤
This helped a lot because I was trying to figure out why my car goes 4 rpm when I accelerate sometimes.
I didn’t know Jordan Peterson did DIY car videos.
🤣🤣🤣
Clean your room, bucko.
Thank you very much. Really informative
❤I needed this explanation..thanks!!
Super helpful appreciate you
rlly helpful thank you
Thank you!
thank you
Woah thank you
thx
It all depends on what gear the cars in at the certain speed your going that determines how fast the engine spins. Example if your doing highway speed well the transmission will be in its highest gear and that’s pretty much a direct link to the engine speed so you probably see an rpm of 2000 doing highway speed. In city driving probably using gear 3 mostly so the engine speed will probably stick around 1500 or less. Every car is different but you want a lower engine speed to save fuel.
Hi , Ryan S . I drive VW Golf 5 1.4 patrol engine and 80 ps . My RPM goes over 3800 when I am at 120 km . Is it normal?
Thanks.
@@todaysupdate6824 it probably means you are on a higher gear for that speed, so if you go 1 gear down, your rpms at that same speed will go down, but it is good that you get low rpm in this occasion because you economize better
@@alesito4469 no if go 1 gear down then rpm will be over 4000 . Ok her I explain ( 3 gear 40 km RPM 2000 , 60 km in 4th gear over 2500rpm , 80 km in 5th gear 2000Rpm , 100km 3000 rpm , 120 3500rpm ) I hope you understand.
@@alesito4469 hi , no if I down the gear then RPM goes up too .
My rpms goes higher than 2,500 with the 4gear @ 50km
Wow! I still didn't know what an actual rpm is? Is it a complete rotation of the drive shaft? Is it a rotation of each piston? Might wanna make the title of videos actually match the content (just an idea) I guess my search continues
Same here still searching
Yeah, that's my question too. What is revolving?
great
Hello, I just want to know why red line in the tacometer , because , I’m worried about this red line to my car tachometer too?
Hello I saw an Audi 2.0TDI which is going up to 6000 rpm while another one 1.8TFSI is going up to 8000 rpm but I know that the TDI is faster and more powerful why do you think the less powerful have a higher rpm?
Fine
Is it good to run the car to the red line time to time ??
Your a great teacher
And you're a beautiful student.
@@mr.burgess2575 and you're a basic simp
Can RPM signal conditions of engine?
Badger?
Top top. 👍
How is the red determined? Most cars specs show a horsepower and torque rating at different ratings and different rpm’s which are always below the redline. So does that mean you can get more horsepower and torque if you hit the redline? Sorry I’m confused
I see this is a year old, maybe you found some answers but I accidentally wrote a novel so if you care to read it, here ya go haha. Firstly, the real 'limit' and reason for redline is to minimize engine damage from over-revving/revving too high. Really the main damage I think, comes from a thing called 'valve float', or, another reason is simply the engine spins so fast it mimics excessive normal-use wear (just hope you have good oil in that scenario).
For the second question I often try to think of it like riding a bike, but that may be a stretch in this scenario. It's complicated and I don't pretend to fully grasp it but here's what satisfies my smol brain. It's like when you're pedaling on a bike, there's a certain amount of maximum power that you as a person are able to deliver to the pedals. And that 'type' of power, AND how much is able to be made, depends on what gear you're in, and at what speed you're going. Low gear = high torque - more leverage - but at the trade off of speed. So, you do a lot of work over a small distance. In 'granny gear' (1 and 1), even if you're carrying a lot of weight, the second you can get any kind of momentum, you can just CRANK the pedal down and accelerate very quickly to the point you start pedaling faster than you, CAN pedal. At that point you simply can't pedal any faster but specifically while delivering MORE power (but then also the momentum part, like a heavy shopping cart doesn't take much effort to keep going, once it's going).
There's also something to be said as to why most trucks have a redline much lower than most economy cars/sedans (4 and 6 cylinder namely, and some 8) and also why formula cars/certain extreme performance cars have such high redlines (12k, even 20k). It's all very interesting.
Why is RPM called revolutions per minute and not rotations per minute? What is it revolving around?
The drive shaft is revolving around its centre point. They’re synonymous so you can say rotations I don’t see why not
A revolution is a result of a rotation/going around in a circle
I drive VW Golf 5 1.4 patrol engine and 80 ps . My RPM goes over 3800 when I am at 120 km . Is it normal?
Thanks.
Yes
Speedometer vs Tachometer which is more accurate
Does it goes to 250 500 750 rpm then 1000 rpm
So for the car to run fast it depends on power or speed?
It depends on the selected gear. Lower gear means more power, low speed and stability while higher gear means less power higher speed and less stability.
That's why it's easy to get a crash when driving at high speeds...
What does more power do though, why would you want it if it doesn't mean more speed?
Second is it accurate to assume, the more the RPM the more fuel used?
@@pfchangas from my understanding, more power = the engine is able to turn faster which the transmission then turns into a greater output for wheel speed and creates a faster acceleration
lower gears are best used when pulling something like a trailer, boat, vehicle, etc
@@aambular thank you!
My rpm meter is at 1 while the car is off what is this?
Badger, is that you?
How to know in which amount of gear you are?
With a manual transmission car you know the gear you're in thanks to the position of the shifter. With an automatic transmission car I think you have a little indicator on your dashboard.
One car has 2RPM when I start.... Another has 1RPM, does it mean the former's engine has worn out?
Does more RPM mean more Speed?
Not necessarily, I don’t know too well about cars but my motorcycle runs lean and loses a lot of power if I have high revs in a lower gears.
It means more accelaration, not speed.
@@thesnjvsharma So even more acceleration can get you slow?
@@mraravind1111 acceleration is one of primary factors changing speed. However, If your other pedals and mechanisms are activated speed will also get affected.
Example, at gear 1 If only acceleration pedal is pressed, Speed keeps on increasing along with rpm. If not pressed speed keeps decreasing along with rpm. However if half clutch and acceleration is pressed simultaneously. Speed will not increase in same manner as in the previous case.
Suppose At Gear 1 you accelerated your car to fullest. You care will speed up to around 40 km/hr and more . Meanwhile in the process, your rpm will also increase leading to 6000-8000 rpm, which is not healthy for car.
At gear 2. You can speed up around 40 km/h with less acceleration and low rpm .
More powers to the engine
So yes more speed
Incredible annoying! I shut off the vid in 12 seconds and went elsewhere
You sound so full of yourself
Man, I wanted to watch this video but I have the volume down to 14 and this guy's screaming is making it impossible.
Deviated septum
Rev up the fryers
Thanks for screaming at me in a stupid Muppet voice! Didn't answer the basic question: what part of the car is revolving that is being measured?
man you sound exactly like michael rapaport
I have a dual clutch transmission.....it seems to change gears around 2200 rpm....and stays at that same rpm when it reaches top gear...is this what it is suppose to do...forgive me I'm not a car guy
I'm trying to get the right pronounciation of the word tachometer. ha
what in the jacksepticeye
Tell your from new york w out saying your from new york.
Video guy : voice 🤣🤣🤣
What?!!!
Omg your voice stopped me 1 minutes in
First of all why do you have to be screaming at us? You're such a bad teacher you even used kilometers just to confuse us even more.
Hey clown, most of the world uses kilometres. Too bad you don't understand conversion.
Damn his voice cringed my ears
boring!
