ABOUT PAPADAKIS RACING:
The Papadakis Racing team began drifting in 2004 and is the most winning team in Formula Drift history, earning the 2015 title with driver Fredric Aasbo, as well as backto back championship titles with driver Tanner Foust in 2007 and 2008. The Rockstar Energy Drink / Nexen Tire Toyota Corolla Hatchback is the latest competition build from the Hawthorne, California, based team.
Team owner Stephan Papadakis is a legend of sport compact racing who began building his reputation in the 1990s with the first front-wheel drive, tube-chassis drag car in the U.S. The team earned multiple records and championships in the discipline, turning in elapsed times and trap speeds previously thought unattainable in front-drive drag cars. Papadakis' successes in front-wheel drive were matched by his efforts in rear-wheel drive when he campaigned a Honda Civic that became just the fifth car to join the NHRA's Sport Compact 200 MPH club.
What should I teardown next?
Yes! love these videos! Thanks for posting! If you got a V160 you'd be willing to tear down I'd love to watch as mine is leaking and i need to reseal it..
Aasbo's diff!
I've always wanted to understand and see a comparison of a gear type and clutch pack type LSD. And a Direct shift/dsg gearbox. And maybe the new Supra? How it's been built/it's underpinnings etc.
very nice exlpaining video If you can show us next time how diff works it will awesome
tear down a 4 piston k24 block!!
"We'll get that later" Famous last words
I say that, end up not finding whatever I lost until couple months later when I don't need it at all.
Rathanak's Life i got this rare skill of making parts dissappear out of my hand and making it reappear 10 years later
Right up there with hold my beer and watch this.
This video told me more about how a transmission works than I've learned in my entire life.
Now you have to worship his giant balls
What a mood
That statement doesn't make much sense
Rebuilding my Getrag 233 (aka Toyota V-160) taught me more than this video by a long shot. Prepping motorcycle engines for racing also taught me a whole lot about "dog" boxes, shimming gears, and backcutting straight dogs. The dogs in this box are undercut as anyone would expect for something at this level of competition, but doing this with inverted cone stones by hand on both dogs and holes is a painstaking effort.
it feels like i am a kid again opening everything to find out how it works 😂
I just binge watched your entire channel, you tear down everything...I love it !
Great content
Yours too
yo dude i love your channel you’re awesome 👏
Hey bro. Love your channel too
Same loving it
Drops almost as many things as Linus Tech Tips, but since they are car parts...they don't break as easily.
@dyy Fethiiyhn I disagree! I don't know if I'd be classified as a "nerd" but I enjoy tinkering with both cars and computers
@@Leviathan431 I also tinker with cars and computers. I made a laptop fan bearing for my laptop last night because it was noisy, and I'm supposed to help my friend install heim joints on all four quarters of his suspension next week.
@@commandohazelnuts It's fairly rare to find people interested in both, but I don't think they're too dissimilar. My PC build is just as unique and personal as my car is.
@dyy Fethiiyhn bit narrow minded but aight
@dyy Fethiiyhn Nerds (ie. engineers) are the ones that design cars, my guy :)
Your videos are incredibly satisfying. Very concise, no distractions and clear info. I also love how you don't edit out the little spills you had, it's sincere and honest. Even the best have imperfect moments at times. Keep it up, I'm a definite supporter of Papadakis Racing!
This is the third video I've seen from you (first two being 2JZ teardown and rebuild) and you're very quickly on track to become my favorite KZhead channel.
Fantastic idea and definitely a great initiative for the enthusiast community who wouldn’t ever have an opportunity for such a guided and equally informative introduction to these gear boxes 🙏🏼
Excellent channel and your production is awesome, simple straight into it no music no tattoos no beard no ego just showing us some cool gear. Thanks.
Awesome video mate, thank you. Im about to pull my own GSR box apart and look over it! This is a huge help thank you
I love how he says “go ahead and...” like we all got a G Force nascar tranny laying around
Love the transparency your team has on these videos. It’s refreshing.
This guy's videos are always right to the point, no BSing around. Thanks
thats a nice video !! Tear down next a dragster small block engine.
Thank you for nice explanation about this transmission system.
Love the format of no bs and detailed video. Kudos for the hard work that goes into producing the content. Also love the way you show what really happens like when you dropped the spring. No pretentiousness. Well done.
I just stumbled upon your videos and wow, this is my kind of entertainment. I have such a passion for going fast and getting sideways and I love to see it all broken down piece by piece. I’ve been wrenching for years and I love it every day. Thank you for the good content. Subscribed!
I couldn't care less about cars or racing. But I love knowing how things work and machinery. I like to see how the horsepower is made. I am glad I found this channel. Everything is basic yet complex. Thanks for making these videos.
I love this guy, subscribed!
How does a guy with a million subs not have any comments on a post
One of the best explanations I have ever seen.
This is the absolute best transmission video I have ever seen on KZhead and I have seen a lot of them whereas other videos are pretty good this one is just so perfectly explained and edited that I actually learned something so I want to thank you for what you're doing
Thank you very much! I finally understand what dog boxes really are.
Top notch content. Simple, to the point & informative. Thanks for sharing. Btw, Stephen, what's your thoughts on the new Supra? Although there is a bunch of internet pitch-forking, I think there's gonna be a high demand along with local dealers adding on "Its a Supra" 10k tax. Being that you guys work closely with TRD/Toyota in Formula Drift, is there a chance that we'll see Aasbo piloting a Papadakis Racing Toyota Supra in a year or two?
Chiming in, I hate internet pitchforking I think Toyota took the success of the Subaru twins the wrong way. Everyone wanted the '86, they made a pure reasonably priced car close to it's roots even though it's boxter engine is a pain is some areas but with just enough to HP to have fun. BMW reputation lately with deteriorating obscenely priced plastics, gm sourced transmissions and massive cost cutting have gutted that brand. Toyotas reputation or over built modifyable engines was the MAIN reasons this car would've sold. Once this car pushes $70k after the stealer tax, that opens up A LOT of other options. They needed to go backwards towards lighter and powerful AND that overbuilt engine. I don't think the BMW engine will cut it. Driving dynamics might be stellar but then why not buy a Subaru twin? They basically competed with themselves
That’s what I don’t get. Why Toyota, known for unimpeachably reliable engines, went to Subaru boxer ( albeit a fine enough engine ) for the 86 and now BMW? It’s the heart of the car! And Toyota isn’t putting their hearts in their cars.
@@blakestone75 At least with the BMW Toyota apparently did a LOT of reliability testing and redesigned whatever failed, so the engine should be up to Toyota reliability standards.
@@MrRedstoner hmmm...I doubt it, they still have a plastic manifold with a intercooler bonded in. It's designed to fail, and designed to cost a fortune to replace, which is now the goals of BMW R&D.
the problem with the 10K tax is people will just logically order a C8 Corvette. Thank GM for keeping Supra prices stable.
I like that you left the parts dropping or mistakes in this video. It humanizes it and it's awesome to see someone as experienced as you still drops things like a newbie would!
Thank you for communicating in a way that beginners understand what the parts are and what they do.
How are you not in the millions of subs? Your vids content is so clean, clear, and well thought out. Keep it up Steph
Beautiful transmission! Thanks for the in-depth look
Ok...now I am hooked. Only saw a tool box tour once and that was good, but now....pulling things apart and showing how it works. Next level.
I drove a Pro Drive rally car with a dog box on it with straight cut gears and it was very loud but you could just ram it into gears without synchros by just coming off the throttle a bit. If it wasn't for the noise they make I would love to run one in my street STI.
You can run dog boxes in street cars, the issue is every shift you make you have to shift with 100% force. The dog teeth will round off and engagement doesn't feel as quick or easy. But STI transmissions are stout, there should be no reason to run one under 800hp if you aren't drag racing every weekend. Even a dog box WRX transmission isn't even half as strong as a stock STI transmission, dog sets aren't always better. I build evo/subaru transmissions every day and it is a very common misconception.
Fancy seeing you here barnacules
I used to watch your 3D printing videos and now I'm much more Into cars, I'd never expect you to drive an STI. Good choice 👍🏻
Thanks, that was a pretty good answer to my question to tabcobra
I went to your page but there is no race car videos? Why haven't you posted your car on your popular channel?
*plops transmission down* I'm snuffleupagus and today we're gonna tear this transmission down
LLLOILLOLOLOL
this is by far the most entertaining, most informative, and most thorough auto channel I have found on youtube. The professionalism and humble attitude of Papadakis is a cherry on time. Subscriber for life, no doubt.
watched a couple of videos on this channel. Great explanation without any fluff. Subscribed.
Very cool. I run two CNC gear shaping machines. I have seen and made so many transmission parts without knowing what they do.
I rebuilt transmissions along time myself. And I wanna learn what you do! Lol
@@TommyZ9448 ....we are hiring. Lol
Jim Scobie where at? I do live in southern Cali. And I’m working overseas but will be home in a year or so. Lol. Planned on doing a CAD program online. Will that be beneficial for me? I’m sure when I go home I’ll work on cars for awhile. But my area has a lot of opportunity for CnC jobs. 🤔
@@TommyZ9448 ...i am near Detroit.
That's not a normal transmission. It's a sequential "crash box" specifically for race applications. A KZheadr named Engineering Explained has some real vids on a normal manual transmission. Look him up.
Next, Formula One Gearbox
Channel named Driver61 tore down an old gearbox out of an old 1997 Jordan. No very recent tech, but the same layout and mechanism.
F1 gearbox isn't that much different. It's straight cut, semi-automatic but more gears. It's only shifting gears faster than a DCT which is quite remarkable.
Excellent explanation and tear down. Thank you for taking the time to do a quality video.
Best 8 minutes of my life. literally I learned a lot about the gears in the ratios are watching this video you have a new subscriber keep up the good work. Can't wait to binge-watch your whole channel.
Helical gears are stronger than straight cut gears. Straight gears are used because they dont produce axial loads like helical gears, so they don't require the high strength axial thrust bearings. This greatly simplifies crankcase design, decreases cost, and most important decreases weight.
And also the cut gears permits the driver to shift without using the cluth, that's mean much smooth and faster shifting.
Semantics.
Bryce Peters not at all! There are real differences and real reasons for choosing one over the other.
@@ChefofWar33 - No it's the biggest misconception surrounding transmission design straight cut gears themselves are weaker
@@manuelcircelli511 true, drivers don't use the clutch. brake and gas all they need lol
Don't know transmissions at all but wondering what parts of the actual case (magnesium vs aluminum) will wear out over time....short of an actual self destruction of the bearings or gears of course. Neat video. You explain things really clearly
fatigue cracks most likely, also worn bearing apertures if replaced often.
Heat will warm magnesium faster than aluminum. Also, bits of road junk getting tossed up case damage.
@@rightwingsafetysquad9872 ... The heat generated by the gears is the same, regardless of the metal of the case. The temp of a mag case will be the same as an alum case.
Simple but bombproof design. Top notch workshop BTW👍
Thank you so much for this video, it has explained so many things that never quite seem clear in other sources. Bloody great video
Steph, you're like the bald one from Brazzers only on the technical side =D
Johnny sins I just noticed too 😂
lol ohh wow
Johnny Sins always lubes the drive shaft so it wont tear up the lip seal. And yes, he uses handcuffs to help keep the shaft from bending. I've seen him tear apart rear ends, too. I consider his videos training videos and hope some day I'll be as good as him if I practice enough. He has the only tool not made by Snap On.
Алексей Антушев he’s also got a KZhead channel. He’s a cool dude. Sins TV
@@juliobello4561 HAHAHAHA
show us how u are to build the new supra for Aasbo to drift and will u keep the 4banger or use the new/old 6 cylinder 2turbo from bmw. keep up the vidz your awsome
Blasphemy! Idk why yota is using a BMW powerplant. Makes me sick
@@athomedetail6512 because it's just better. Stop hatting on the superiority of BMW.
Loving the engine and gearbox content lately. Tbh I was glad to see that he's human after watching him drop a couple of parts. I work on the line at an engine assembly plant and this guy is next level.
Ive seen this explained many times but this is the first time i understand the shifting. Thanx dude!!
I rebuild manual gearboxes myself but I’m curious what you inspect on the dog box transmissions? Obviously there aren’t any synchronizers to wear out. Do you find the drive teeth on the gears worn out usually? Or do you just replace the dog engagement sliders to prevent future damage?
Majority of the dog boxes ive built for the racing guys and come back for a overhaul after a year or so.. the main problem ive found is the quality of the gears! The majority of them have gone through the case hardening on every gear plus laygear! For how much the customer pays for the Quaife gearset alone and the state of it when it comes back for a rebuild is a joke!
If you look, you can actually see that the pocket on the dog he showed up close was deformed at the root of the lug.. Obviously the other part is looking for tooth wear and of course, bent shift forks.
I work on motorcycles and they use dogs for engagement of the gears, a common issue is dogs rounding off from poor shifts and the rounded dogs act like ramps and pop the gear out of engagement. I see it a lot on the lower gears like 1st and 2nd. also the shift forks being bent can cause the rounding to start happening because its not pushing the gear firmly in enough. Transmissions meant for high engine power will use undercutting on the fixed gears to make sure there is more positive engagement to prevent dogs from not engaging enough and start getting rounded.
Jl4zio Yeah I see that in Automotive gearboxes too. I’ve built dog engagement gearboxes for customers but I don’t ever get any in for maintenance, so I didn’t know what would wear first; the lugs or the drive teeth.
Usually it’s because you sheer the teeth on one of the gears.
Are you building the new Supra now?
Nice transmission...thanks for the crisp description of how it works and comes apart.
Thank you for this. I've watched a bunch of videos and read many things online but your video helped me finally understand what was going on in a manual transmission.
I wish NASCAR would market the fact that they use manual transmissions. Modern race transmissions with paddle shifting blow these out of the water, but it is still impressive to watch a skilled driver shift and work the clutch. Even if it's not true, NASCAR could assert in their marketing that their drivers have more skill and their sport is a truer racing sport. Obviously it would also be nice if they raced fewer oval tracks otherwise I suppose no one really cares about the transmission since they hardly shift.
You do realize that a good portion of nascar tracks aren't just oval tracks right? Watkins Glen is raced at numerous times during every season and that has definitely got more than 4 turns lol.
@@65Red Yea I know there are of some tracks raced that aren't ovals. I said it would be nicer if they races fewer ovals
FYI there's not one "STOCK" about Nascar. They need to rename it, rebrand it. Whatever, but please don't call it Nascar or stock car. It's not symantics, it's B.S.
@@Dauntless.steadfast.fortitude What are you talking about? Obviously they are not stock cars in the sense that can go buy one at a ford dealership. It hasn't been that way in many decades. Stock-car is a generic term for the vehicles they race. Don't call them Nascar or stock cars?? So what are we supposed to call them. Quad wheeled racing chariots? Would that be better?
@@invsiblshowercurtainmy point exactly, Not stock cars since late '70's early 80's...so rename it, up grade it...you made my point for me. I'm sorry if I hurt your feelings, didn't mean to.
That was all nothing but machining porn for me. I will be working for a very long time for one of those.
coming from the transportation field having worked on passenger car, light and heavy duty truck transmissions, I found this video very interesting and informative. I have not had the privilege of working on off-road transmissions. thank you for the informative, graphic representation.
Transmission really is much more straight forward than I thought, thanks.
I wish I could carry my transmission around like that, almost gave myself a hernia trying to move my 4l80 lmao
Lmao yeah them Chevy transmissions heavy af
Dude... that's a race 'box lol ofc it's that 'light'
James Davis someone’s mad 💀
Standard shift trans are typically lighter
When you try sooo hard not to let a bold or spring fall then it falls😂
I have no clue about racing in general but you always explain with ease and I feel like I learn something each video I watch. Thanks!
The sound of a straight cut gearbox is music to my ears. Great video.
jmurphy1973 Real question. How is the sound? Is the whining you hear in race cars? A little similar to a differential going bad?
staight cut gears are not per say stronger. most of the time bevelt gears are stronger because more teeth are engaged at the same time. however beveled gears create a lot of additional forces.
Axial load
@@MrMattydavee jep axial loads. those are quite hart to deal with. so in a race car aplication a light gearbox is nice. but to make it light they have to remove material. that makes the box itself less stiff. that in turns causes missaligment in the gears. and staight cut gears can deal better in those conditions.
Lots of research shows that straight cut gears are stronger due to the teeth actually being thicker for the same ratio. With helical cut gears, the teeth have to be made with less material to mesh properly.
Steven Boyd not how it works but okay
craze09 goes against every reason that people use straight cut gears but ok. If angle cut gears were stronger, there would literally be no reason to use straight cut
How would these actually last for a daily driven vehicle and how is the drivability of these
This unusual question ran through my head as well... I wonder what it would be like in my daily driven gto?
@@seanykinz a nightmare. it's a dog box transmission. these suckers are built for high horsepower, not as small as a daily driven car would have. you have the physically smack these puppies into gear, because of those dogs. they are very hard to drive with in stop and go traffic because you have to run through the gears, as this specific one is a sequential gearbox. some are a 4 speed H-gate, where it's a little easier to run on a daily driver (I have it one my s14, it's not bad). to conclude, a sequential dog box tranny such as this, would be a nightmare, and won't work well on a daily, mainly because of the relatively low horsepower and different drive train.
Just like a regular gearbox, except with stronger gears. With only 4 gears MPG will suffer, but they work just like a stock one. Advantages are availability to change gear ratios. They are like an update of the Muncie 4 speed of the 70s.
@@lincolngolladay nascar boxes are H pattern, no fancy techno sequential.
Really bad drivability having straight cut gears instead of helical gears makes the car jerky and violent while shifting or taking off and the ratios are not suitable for street use at low rpms and speeds plus these transmission like much of the parts you'd find on a track or race car are basically consumables made to be used worn out and replaced so it wouldn't be reliable
This fella is a genuinely nice guy and a brilliant mind! Thanks for your videos friend.
appreciate all your awesome and informative video's Stephen! Truly a class act in every fashion, as all too often engine builders will only show/explain the inner mechanics by literally talking - no video..... which I can understand for obvious reasons - competition! thanks 👍👍
I am honestly surprised there is no overdrive on these just a 1:1 ( direct drive )
No overdrive needed in a nascar, opbviously built for WOT and high revs.
Actually, you can make it an overdrive by setting up 3rd gear as an overdrive, the shift linkage is changed for 3rd & 4th, 4th 1:1 becomes 3rd and 3rd becomes 4th overdrive, The gear sets are interchangeable as underdrive or overdrive. If this makes your brain hurt, I am sorry. From Russia, with LOVE.
Straight cut gears aren't stronger, helical gears should be stronger due to more teeth being in mesh with each other. Plus they are quieter because of that. Where straight cut gears help is because you don't have axial force acting on the shafts, like on helical cut gears, you don't need the casing to be as strong axially, only radially between the two shafts. That's why a straight cut upgraded gearbox (in factory housing) for a road car is stronger, it doesn't open up the casing.
Thank you for this little walk around w/tech verbiage :) Love this Buddy!
I watched this before, I'm watching this again. I enjoy your teardown videos Mr. Papadakis.
many folks may not know that is a constant mesh transmission, where the gears never disengage, only the dogs, via the sliders. Most factory transmissions the gears fully disengage or engage every shift. This style is most common in motorcycles, as in all motorcycles use this style. Would love to see a sequencial box tore down, if only you used them.
Nearly every factory manual transmission is a constant mesh. The only difference between these gearboxes and the gearboxes in street cars is the shape of the teeth (straight vs helical) and the way gears are selected (dogs vs synchros). Synchros serve the same purpose as the dogs do, only they are much smoother and you don't need to rev match, but you do have to use the clutch.
@@bman12three43 you are so wrong. factory transmissions disengage. the syncros are brass, and cut so the gear trying to engage it connects with syncro, that has a friction clutch inside the steel gear. it then causes the steel gear to match speed of other gear which allows them to ebgage without grinding. when you have constane mesh and dogs, you have no need for syncros. you contradict yourself. Don't post your opinions, it is a dservice to present opinions as facts. I've been working on cars since the 60's. Chevy's Rock Crusher, the M22, in all performance cars in the 60's and early 70's had straight cut gears and no syncros. You had to use your whole upper body to "bang" gears or rpm watch with throttle, or they wouldn't engage and they would grind the corners off the teeth. go take apart a manual cars trans, and a motorcycle trans and tell me they are the same. I've rebuilt at least 10 car and 50 bike transmissions.
@@WelLRoundeDSquarE I don't think you quite understand what I am saying. Let me read you some lines from Wikipedia: "The gears were typically engaged by sliding them on their shafts (hence the phrase shifting gears), which required careful timing and throttle manipulation when shifting, so the gears would be spinning at roughly the same speed when engaged; otherwise, the teeth would refuse to mesh. These transmissions are called sliding mesh transmissions or sometimes crash boxes, because of the difficulty in changing gears and the loud grinding sound that often accompanied" This is where the gears are not meshing and you force them to mesh right? Now let me read another line: "Newer manual transmissions on 4+-wheeled vehicles have all gears mesh at all times and are referred to as constant-mesh transmissions, with "synchro-mesh" being a further refinement of the constant mesh principle." Hmm, gears that mesh at all times, that are called constant mesh transmissions? Go ahead and send me a picture of a synchronized manual transmission where the gears are not meshed at all times. Here are some examples: i.ytimg.com/vi/vOo3TLgL0kM/maxresdefault.jpg Well look at that, all the gears are in mesh. i0.wp.com/www.econofix.com/mtrans2a.jpg Here's another one, still in mesh. kzhead.info/sun/qbOoY7iEnn5mnoU/bejne.html Oh heres a youtube video where you can see all the gears meshing constantly.
@@bman12three43 I stand corrected. Thank you for forcing me to look into this. I am humbled and always greatful to learn . I appreciate your efforts to make me research a bit. Peace to All
Huh? Every transmission in almost every manual car is constant mesh.
*Q. What do you call it when you blow up a dog-box on the track?* *A. A cat-box, because you have to clean all the litter from the track.*
I could never understand how transmissions worked because I never got a good explanation and this just cleared up everything! Thank you!!
A legend. Thanks Pops!!

Eric S You would just have a 4speed Ford or Chevy.
@@tabcobra And that's a bad thing? I'm a simple guy.
Eric S Didn’t say it was bad at all. Heck, I have a 4 speed toploader behind a big block Ford in my 427 Cobra.
@@tabcobra I didn't see any synchronizers in there, how would that transmission be as a daily driver?
@@jimsz0100 It would be fine, but just four gears...
Straight cut gears are not stronger
You're right, but because of the reduced parts it's overall more reliable when abused and the gears are a little bigger and wider than they otherwise could be. That may be what he meant but I'm not sure.
Clear explanation - great video. Keep them coming.
Hands down, the best transmission intro video ever. No animation or complex explanations, just actually showing how it works. You should consider a video "school" on mechanics, like the military has attempted. You would succeed where others have failed. Watching something work as the basic principles are explained prepares one for the more complex or in depth concepts to come. I learned best with hands-on experience, but this was just as clear. Bravo Zulu, we'll done!
Wrong. straight cut gears are not stronger! they are same or even weaker than helical cut gears. They have smaller contact pattern, never wandered how can they be stronger? Only one difference that straight cut gears don`t have axial load while turning. Lower forces means smaller bearings, smaller gearbox case, lighter more compact gearbox. Lighter car = faster car. Downside they are loud, but who cares its a race, people want to see loud cars :) So that`s why you see helical in every day car and straight gears in race cars.
This guy has never had a race car in his life. Let me guess you read that in the textbook, ASE manual transmission test. Theory doesn't always apply in real life my friend.
@@joneskey3950 let me guess physics does not apply to race cars?:)
He's right, he could have said it more subtle though. A "common" failure mode in gearboxes with helical cut gears is gearbox case breakage or thrust bearing failure
Well then wider tires must grip better right.... wrong surface area has nothing to do with grip it is determined by the pavement surface and the tire compound.
To be fair tho yes they have less axial forces so the transmission as a whole is stronger not just the gears
Super cool man. Love the details and how you name/explain everything in the tear downs. More info the better 👌👌
Awsome video I am so impressed. Keep up the great work.
I really enjoy your channel. You are an excellent teacher and make these complex machines make sense to the average person. I also like how clean your shop is and how orderly you are with your gear. Thank you!
