  1. My only question is how can someone dislike an educational and informative video that doesn't cost anything?

  2. If the only reason to use a pucked design is to increase the surface pressure, why not just use a stronger diaphragm spring? Doesn't the reduced surface area decrease the amount of friction by exactly the same amount that increased surface pressure increases it? I'm figuring based on the simple equation for static friction. Perhaps I'm missing something. Is the coefficient of static friction for the clutch material not constant with pressure?

  3. What's the difference between a 6 Puck Sprung and a 6 Puck unsprung disc?

    Don't know which one to get. And it says it requires a flywheel counterweight

  4. i dont understand something: u say less area of the disc, more pressure, thats ok but u also have less area with frictional force, so how does it benefits at all the transmission of torque?

  5. Quick q? I got 350miles on a stage 3 clutch im boosted like 340hp i tried to punch it the other day in 2nd gear and it slipped do u think i might of alrrady messed it up

  6. Can you do a video about how to properly break in a clutch, the do's and don't's? This is a highly debatable topic with not the greatest answers available. Also the break in period being different depending on the clutch material.

  7. I really like watching your videos. It's very cool that you get into all the corners and don't leave out any details of information. Watching your videos is like going to a mechanical engineer class with a awesome teacher that has the patience and humble attitude to explain and teach with real examples how and why thinks work the way they do. Thanks for taking your time man. Many of us appreciate your videos.

  8. Thank you. Great video. What about flywheels if the car is to be used on a short circuit arranged by cones? Slalom on a parking lot, with very short straights (less than 15 metres) and sharp corner (90/ 180 degrees). Lighter flywheel or heavy?

  9. 1800lbs of clamp and its a 6 puck? Oem ford focus st clutch can hold 400 l
    Ft lbs of torque with out issues. That's a organic clutch out doing this "performace"?

  10. So my clutch went out, guess its pretty normal with 2015 WRX's I am looking to either get a new clutch from the dealer or start building my car, however I need to know what would be good for my vehicle. By the end I will be looking for 500+ hrp however I am looking to do it slowly not getting all the parts at once. I'm not sure if you can do that with clutches, so was sort of looking for some help if anyone has some suggestions.

  11. keep in mind viewers are watching from other regions of the country/world where English is not spoken as "fast" a little bit slower pace would be okay. ☺

  12. I’ve just bought a 6 paddle ceramic clutch, says I should do a 500 mile break in, how do I break it in? Is there anything I should specifically do or don’t do?

  13. Heavy duty clutch doesn’t protect the gearbox from more power in anyway does it?

    Also, when you push the clutch pedal, the clutch is separating from the pressure plate or the flywheel? If yes, does the clutch permanently stay in contact with the flywheel?

  14. After replacing the clutch also still I feel the pickup is low. Changed the spark plugs too. I could not able to diagnose the culprit. Could you please guide me

  15. Ok so if i have a stage 2 ceramic clutch in my subaru does that mean i woulf be able to launch at higher rpms without damaging the infamously fragile 5 speed?

  16. Be warned if you daily drive in traffic you will find a performance clutch to be very ill suited. They are great for track use with a car that has mods that increase hp by a very high amount over stock. To say that they chatter, grab too quickly, and can make your clutch pedal heavy is a huge understatement. Please do more research before going with a performance clutch. The info in this video is correct from an academic perspective, but understates the draw back for the vast majority.

  17. So quick question, whats the best option for a guy like me who wants a stage 3 clutch with the softest possible engagement / stiffness / hardness? More pucks or less pucks? Sprung vs Unsprung, etc. @ Engineering Explained.

  18. Hold on. Isnt the puck concept controversial? By reducing the area you increase the preasure applied to the area by elimination of displacement space. Sound math, however, its done because the material needs more preasure to apply grip/traction/friction? Wouldnt a bigger surface area increase the amount of friction that the clutch applies to the flywheel reducing the amount of preasure needed to grip/get traction/friction ~ spin the flywheel?

  19. What Stage clutch can I get away with using on a 450hp 1997 LT1 Camaro? Looking at one with a Stage 3 clutch, and I want it to be streetable, and reliable.

  20. Wow! Good job! I'm doing a clutch replacement and was hacking at videos. I had not interest in this one but curiosity got me. I watched it and I'm so glad I did. I bought an upgraded clutch for my car and now know the difference between the two.

  21. Can I swap automatic transmission for a manual on a 2006 3.5 Altima and be able to fix ck engine light still using the OEM ecu

  22. maybe someone could help me with this. why use a performance slipper clutch for greater torque when u could just use a standard clutch which has much better torque by default and just learn how to drive?

  23. I own a 2015 wrx with 26,000 miles. Got it off the lot brand new take good care of it oil changes every 3k or so miles. I just recently did the stoptech front and rear brake kit, and replaced all fluids (front and rear trans fluids) with motul gear oil and gear 300. Also i had a clutch kit installed the clutch kit was the act II performance street friendly clutch kit. I had all this done by a mechanic. (I do believe either the engine or the transmission had to be taken out. Today i got my car back and now I can hear a ticking noise when im accelerating. It sticks around when i shift into other gear and driving too. The damn thing was functioning fine until i went to the mechanic any answers to this? Please help

  24. Forgive my ignorance but how would one break in a clutch on a racecar? A drag car for instance… You can drive it 500 miles before ripping on it at the quarter mile. What's the solution???

  25. Die you ever resurface, or 'turn' a flywheel when installing a new type of clutch, or does the break in take care of that?

  26. I have a question. When did diaphragm style pressure plates become so favorable?

    There used to be 3 main styles of pressure plates back in the 70’s.

    Borg and Beck (GM vehicles), Ford Long Style (Ford) and Diaphragm which was used by everyone.

    Diaphragm was the smoothest and most tame. Borg and Beck had 3 short and wide arms that contacted the throwout bearing. Long style had 3 long and narrow arms.

    Long Style was the better of the 3 styles. Nobody used diaphragm style on hot rods. Borg and Beck was the most popular.

    I had a big block Chevy back then and I custom ordered a Ford Long Style pressure plate from Weber clutches. It worked amazing.

    I was in high school at the time and chose that style after reading a comparison article in a hot rod magazine which explained because of the added leverage of the long Style, you could run a stronger clutch spring and push the pedal easier.

    So what changed? I’m guessing the popularity of automatic transmissions in V-8 automobiles?

  27. Do performance clutches reduce rev hang when shifting into higher gears? I’m looking to upgrade the OEM ‘13 BRZ’s clutch, and I’m thinking about putting in an Exedy Stage 4 clutch.

  28. in a dual clutch transmision which clutch is better to be used: a performance or a casual one?
    also does anyone knows a good website or book to design clutches?

  29. Bruh, carbon clutch you can beat the shii out of and drive away compared to a stock clutch will fault. Simple right lol 😂

  30. Jason, could you provide any information you have to the downsides of a single mass flywheel in terms of component damage to the drivetrain, gears, etc? and if I'm upgrading to something like a stage 2 or 3 clutch, is it completely senseless to stick with the stock OEM dual mass flywheel? trying to order soon as clutch is slipping hard on the n55 and needs replacing asap. Any help would be awesome.

  31. Absolutely love how you explain things. Makes it so much easier to understand! Videos are helping a lot of people out keep it going

  32. Okay I’m looking to use my Lancer equippe as a hillclimb car, I’m wondering what parts I should upgrade to make it more durable

  33. What is the difference between a sprung and an unsprung clutch disk? When putting in a performance clutch, is it okay to reuse stock flywheel or should it be replaced?

  34. I have a 05 350z and I just put in a stage two 6 puck clutch. I do get chattering when I’m engaging 1st gear or reverse. Will it go away over time or will I adapt too it?
