This man produces some of the most informative and easy-to-understand car-tech videos on the internet. It's not just that he answers questions people have, it's that he's good at explaining aspects of each concept in the correct order for best comprehension.
Great video, had a neighbor kid install a race(metal) clutch and it lasted only a couple months in an everyday driving application. What a waste the kid would not listen. He wasted so much money. Nice thing he owned up to the mistake and installed a street clutch that lasted several years now.
I was about to write the same thing. Finally I feel less like idiot - the biggest art is to explain so that everyone will understand. I belive that channel has accomplish that.
Very well explained and thank you for including the downsides. When modifying cars I find people tend to mention the pros but not the cons of a product. I didn't know you could get multi-plate clutch conversions, that's new to me. I don't like using the word upgrade for such things as they are also a downgrade in many ways, they're more of an alternative.
I get your point and a few people commented about the upgrade wording already. However, it is an upgrade and not an alternative when you're increasing power and torque. It's an upgrade because it's getting you what you need at the price of something that's less relevant in relation to the end goal of a significantly modified vehicle. A bulletproof vest is definitely an upgrade from a t-shirt when you're trying not to get killed. Yes, it's heavier than a t-shirt but that's irrelevant in respect to your goal and a very small price to pay 😊 a weird example but you get the point
Yes, there are downsides but there are exceptions also. clutch choice is very difficult and good ones can be very expensive. Just because you have a twin plate doesn't necessarily mean it's always less drivable, chatters or is heavy under foot. In my instance (2.4L stroker motor in a evo TME) the stock clutch is very light, so a little extra pedal feel makes it easier to predict clutch take up, still being a sprung centre means it doesn't bang on engagement and the right friction compounds plus double the amount of friction material means it's relatively easy to drive albeit able to cope with more torque (739nm on run in tune, low boost).. My wife can drive it, and in traffic with little fuss. I was lucky, I got my clutch for free, my brother was the sales rep and they used my car as a test bed to make a capable but user friendly clutch.
You are so easy to listen to. Well-articulated, not mumbling and no hum, well, ehh sounds while talking. This is unique. I have learned so much. I am surprised there is no way of sponsoring your channel directly.
Multiplate wet clutches usually found on motorcycles...being immersed in oil would reduce friction which seems to operate counter to what you want to do. Some high performance cars use wet clutches too. Please discuss. Love the channel...looking forward to next instalment talking about flat engines aka 180° vee config.
Motorcycles usually get around this by having a lot of plates, sometimes 6 or more, so there is a huge amount of surface area to combat the friction loss from the oil.
Yeah, I've got an Evo X which has a dual wet multiplate clutch (about which I know almost nothing). I would love to see an in depth explanation of how it and similar clutches work. Please?
I'd really like to know why multiplate and multiplate-wet clutches aren't more common in cars. I assume wet clutches have a major downside of gumming up whatever oil they're in. But what prevents multiplate clutches being the norm? Most motorcycles I'm aware of only ever run multiplate. Engagement with those is so light, it can be done by hand. I can't imagine the price gap being so terribly wide when done at the OEM level. At least, please say it's not built-in obsolescence...
@@ImnotgoingSideways motorcycles get around this by have a unique oil spec (JASO oil class MA) the MA means that the oil is capable of suspending the additional sediment from the wet clutch, and doesn’t include friction modifiers that would cause undesirable clutch slip. Additionally, bike engines also need to have different additive mixtures in them as the engine and transmission share a sump. (Motorcycle engines also run a fair bit hotter and spin faster than car engines which also effects oil quite negatively as well
I love how you tend to start with basic components and introduce complexity as you move through the lesson. This provides an excellent understanding of the drawbacks of the basic components and also gives opportunity for discussing the pitfalls of these more complex solutions. Nothing comes free in this physical world, and I feel that you are dedicated to teaching this. Good work!!
I learn something every time I watch your channel. You do a fantastic job of summing up information in a meaningful way. Really appreciate all the work you put into the content you prepare.
Absolutely LOVE the informative videos you make. As a kid who grew up working on his own vehicle in the 70's I have seen all sorts of engine parts but I never fully understood how they work. THANK you for the time and effort you spend bringing us these well done videos! Be safe and stay well.
Your graphics were priceless. But the _hand-gesture_ @6:20 ..? I can't imagine what I'd be grabbing ... (with 2 hands @ chest level, in a squeezing motion).
So satisfying to see your subscriber count sky rocket and sponsors jump on board! Fantastic video as always. P.S. Organic is clearly the best because the strength chart looks like a Star Trek symbol. ;)
Clutches for a semi trucks have a similar construction but also offer one more feature that you dont find in cars. That being a clutch brake, it is needed to slow the transmission down/stop so we can get the truck into gear. If the brake was not on the clutch it would several seconds for the transmission to slow down enough to get it into a starting gear.
For a car yes, synchronizes are used to match the gears to the engine. A transmission in a semi does not have any synchronizes in it. In fact a semi transmission is split into 2 different parts. Engine side and road side. The engine side had all the gears in it that you would normally shift through. When you depress the clutch in a semi and dont engage the clutch brake the transmission can be felt still slowing down and grinding to a stop if you try to force it into gear. A clutch brake actually stops the transmission so that the driver can get into a gear from a dead stop. Once the truck is moving the clutch brake is no longer needed. In order to shift the truck, because it is not synchronized, you have to double clutch or float the gears. Now comes the other side of the transmission, the road side. It spins with the drive shaft separate from the engine side. If i have the clutch brake engaged and the truck is slowly rolling the truck will not go into gear. So the truck has to be at a full stop or, you let out the clutch and match the gear and engine speed so you can keep moving. It is hard to explain how it all works but i tried my best so hopefully it makes a little since. If this was something you already knew i apologize for that too.
I watched a few youtube videos and I still got left confused to which I should put in my car. thanks for this man I know exactly what to get. btw this guy knows how to explain his stuff!
Ah, this is a very welcome video! It makes it very clear that the people buying ultra aggressive (race) parts for daily driving are.... not choosing wisely. :) Of note, the company Spec has a lighter than OEM clutch pedal feel (ie. requires less foot force), despite the clamping load being higher. I previous ran a Exedy/Daiken OEM clutch in my 2006 WRX for 6 years - no issues with it, other than being 'vague' with engagement (this is expected in an OEM clutch). My transmission had to be pulled as the Exedy OEM throw out bearing was dying, I opted to have a Spec Stage 1 (organic) clutch installed. The clamping load is considerably higher and the pedal requires less effort. From the rumors that I've heard, Spec re-designs the springs in the pressure plate, and that is the result. I do not have any further details, but that rumor is validated in my experience.
After having worked on cars for a number of years, this video still answered a lot of good questions that I had about clutches. Thank you for posting it.
Very useful. Comprehensive. Well researched. And covers the material science in depth in addition to the dynamics. Much of what is being described here about friction materials also applies to brake pads.
Even though I drive an automatic Volvo station wagon I still watch these videos for some reason. I have literally zero need for this information but I still watch. lol
I rebuilt a 1925 Cadillac. It had a flathead V8 engine which had more power than most cars of the day. I was surprised to find it had a smaller diameter- about (7 or 8 inches) but more interesting, it was a stacked clutch assembly with no fewer than 7 clutch discs, separated by splined plates making it very similar to those very small clutch packs in an automatic transmission, although it was a dry clutch.
might get lost hope you see it, could we get a video like this on fly wheels and are we maybe going to see a transmission school coming soon? no pressure, you're just the most unbiased and direct with information, without unnecessary theatrics. the whole engine school playlist can be pretty grueling and it is arguably university 101-303 (on some stuff) in the series; other creators tend to 'sugarcoat' the level of depth some of the information has. You do not. you also don't rabbit hole and go off on tangents. its incredible how professional you are. Thank you immensely for this whole channel and the series especially, thank you so much
The end of the video made me feel MUCH more comfortable with the fact I purchased a stage 3 sintered metal clutch and light flywheel from Comp Clutch for daily use
I never knew there were all iron clutch plates, so learned something new. Also, if you haven't done one, a video on different flywheels would be awesome, lightened flywheels etc. And dual mass flywheels, as I never knew they existed, pretty cool!!
I started my career in motorsport and was immediately acquainted with twin plate sintered clutches with no shock absorbing springs. It wasn't until a few years later that I became familiar with road clutches and I initially found them very confusing. Kind of back to front compared to most people I guess.
Wow. Thank you! I have been looking at upgrading the clutch in my Forester. Coming from commercial applications, I'm not used to the slippery feel of the OEM clutch. I'm getting ready to do a tune up and replace all the fluids anyhow, so might as well pull the block and replace it with something I like. Your channel is always very educational.
This video confirms the quality of your work mate. Overall I think a Kevlar clutch could be an interesting trade-off for tuned motorcycles not going on track
Very interesting, my car goes through a clutch every 6 months but I’m unsure about upgrading because I don’t want it to change how it drives! Lots of good information here so thank you
In addition to the three you mentioned I think larger diameter of the friction surfaces can increase performance also...of course possible only if space allows it.during the design stage.
my jag x-type (the cheap one, calm down) had a organic multiplate cushioned organic clutch. it was hydraulic too and sprung and it felt amazing! at least until the flywheel gives up the ghost and starts rattling.
Love the info and clear way of explaining things! Only thing I don't like is that he is practically whispering 70% of the time and it just gets really hard to understand sometimes.
I remember back when “CenterForce” centrifugal clutch’s were available on the market. It was an excellent upgrade and really squeezed the power out of the motor.

have you heard of carbon clutch. im looking at a clutch for a 17 mustang and saw carbon. thoughts
Kevlar is actually a trademark name as kevlar is just a brand. The actual material is called aramid fibre! There are multiple companies making this stuff
BRAVO MY DUDE !
Para aramid to be specific. There are also meta aramid fibers such as 'Nomex' which have lower strength but excellent heat resistance.
@@nerd1000ify okay, it depends on how you translate it to englisch ofcourse haha
So just like the use of the term "Velcro" which is also a brand.
@@official_commanderhale965 totally correct, but the only language where that really happens is in englisch, in case of the velcro then
"I caught you slipping, fool.."
"Get a grip.."
"In the clutches of the enemy.."
