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. - Авто та транспорт
Damn!!
Unbelievable that a racing team would expose their problems and explain them to the public.
I have even more respect for you and your team, and thanks for doing these videos!
Cheers!
I'm thinking exactly the same now. Big respect to S. Papadakis for doing this.
That's because it's just drifting where engines/tunes/turbo's aren't controlled/parity and they aren't looking for tenths of a second in engine performance.
Pretty damn cool. Much respect to Papadakis Racing for the exposure and education.
I've seen multiple Russian drifting teams showing their problems, quite common there. But so far I haven't seen a racing team to film the teardown of their engine in a tutorial-like format. Evil Empire drifting team films their blown JZs teardown in a life-blog way.
Btw, in drifting the control and handling is more important than power if you have the skill to use it. Gocha became world champion with just an SR20 and 500hp, and he can keep up with his friend's 1200hp gtr. But still the more power the better if it doesn't mess up throttle response and weight distribution of the car.
sasja de vries oh, for sure. I’m just impressed because they are a big-time Toyota team; they’re not exactly in the gamma delta iota fraternity (G*d Damned Independents) running an sr20 or a 2j, etc...they’re producing 250HP per cylinder! I think that has to be the exact definition of high-strung in mechanical terms.
That good feeling when you see a new Papadakis video.
it is a privilege to watch this man work and hear him teach! Thank you again for letting us stand over your shoulder and learn. Best of luck next round! Can not wait to see it
Damn, when I was in high school I used to see this guy in magazines in early 2000s. Record numbers.
Dvs shoes drag car. I remember the articles in import tunner

Don't ever rule out that spark plug being bad straight out of the box. Thanks for the update
Thats like a 1:1,000,000 chance.
Now, me and the mad scientist got to rip apart the block... and replace the piston rings you fried
manifold warning!

Wrong movie, but I assume there is need for overnight parts from JAPAN
@@thor-ericsson yeah, this thing will decimate all after they get some overnight parts from Japan.
But it's going to cost 15 grand, or more

Three things I love about this channel!. 1. You tell it how it is, you're honest and upfront. 2. you make it very easy for non-savvy car people to understand and 3. The videos flow very nicely and don't feel rushed even tho they are short and to the point. Keep up the great work team!
This guy real deal to autosport 👍 right and simple gives you all important information. Luv your chanel!!!
I really don't think you cracked the porcelain. Is it more probable someone down the parts supply chain dropped it. That being said, I respect that you took yourself out of the equation for future plugs, with the gapping tool. Awesome vid
Obviously we can not say for certain who caused the porcelain to be damaged on the spark plug. However I have scene plugs damaged by the tap down method of gapping spark plugs. As a result of that I log ago stopped closing the gap on plugs that way and depending on the plug gap I either use a old style plug squeezer or an electrode bending tool additionally I have found that on conventional plugs a little careful work with a Dremel tool and a sanding drum cleaning up the profile of the ground strap can make a difference with help controlling detonation. After re-profiling the ground strap I make sure to throughly clean the plug before installing them in a engine.
So you are saying the box, and cardboard sleeve didn't do their job? Actually the plugs he buys may even use a plastic sleeve. Dropping spark plugs usually cracks the nickel alloy electrodes inside the plug, sometimes I have even pulled the entire electrode out after this happens. The ceramic insulator is aluminum oxyde, but both if cracked instantly let you know at startup. And once they are cracked they are cracked, there is no in between. So he would immediately know at startup after he installed cracked plugs. And also there is obviously more than one there cracked. This indicates some other issue. Like excessive combustion chamber heat. Indicated by melted underside of the pistons.
Can't say that I've caused an issue by tapping plugs down for the last like 15 years. But I also have never installed plugs on something pushed quite as hard as that engine. A few 1000 hp plus drag cars but not running that high of boost or for prolonged runs like drift
I don't think the porcelain broke before the failure. Detonation and excessive heat causes the electrode to expand and break the porcelain insulator. I think the tune was a bit aggressive and that cylinder was a cunt-hair hotter than the rest and/or the design of piston itself had a sharp edge that didn't get sanded down. Look where the detonation happened , right where there's an edge.
@@NickKautz exactly. Hammering detonation did that. Why? well thats where the story begins . . .
Pre-ignition from spark plug ceramic chips....who would have thunk it.
Doesn't take much when you're making a 1000hp from a 4-cylinder 3L engine.
Maybe one who can read the ECU of the car
Happens
Thunk🤣
Only happens on a 250 hp per cylinder purpose built 1000+ hp race car!
First off I want to say I have mad respect for this video and you. You didn’t hide anything you were open and clean about it and that’s honorable in today’s world. Also you create some of that absolute best engine build and tear down videos ever. This channel will blow up! No music no nonsense just educational stuff with a high quality camera. Thank you
Ha! Just learned more in nine minutes than in years of building stock engines. Fascinating analysis.
When watching UA-cam and you know it isn't waste of time. Top quality content dude, thanks.
This channel has greatly raised the bar on explanations and tear down. The quality and narration was in a different league 👍🏽
Dear PapadakisRacing,
I am not sure if you will ever see this comment, but I hope the energy goes your way regardless.
Thank you for being so forthcoming with your knowledge. As a young engine builder and fabricator, it is difficult to find people in the industry who are willing to share information if you don't work there and that can be discouraging. Thank you for the constant updates and full documents of teardowns and builds. I appreciate that you show when things don't go according to plan. I think few fans on UA-cam realize the balls it takes to not edit out things that look "bad" (ex. When the cam didn't come out of the Supra motor and you had to lean on it). I appreciate these things as it helps eliminate the illusion that when you become pro, or a pro team that life still doesn't throw you curve balls. I respect your honesty, as well as creativity. Keep up the good work, as you are one of the few people to "look up to" in the drift industry.
Blessed and Safe Season for you and the Team at Papadakis,
Adam.
P.S.
Thank you for not running LS 😊
you really couldve just turned the radio up and kept driving. she'll be fine
Honestly
A smiley sticker on the warning light, good as gold
It's all good, being a 2019 Corolla, just pop it into your closest Toyota dealer for a warrant repair 😜
It takes a humble man to admit his possible mistake in his profession and share it with the world. We could all learn a lesson from this and I'm not just talking about cars
Lesson learned don't tap spark plug against a socket...got it. I love watching these videos very informative. Love this channel
It's cool to see you be transparent about failure. Whatever the cause the engine failed and you own it and rebuild. Awesome to see how logical and methodical you approach such an issue!
Really strong bottom end with excellent lube system design, no bearing damage even after putting a hole in the piston and the crankcase overpressure blowing out the seals and losing a bunch of oil. Great engineering, great video, thanks guys.
Another great video Sir. To any aspiring technicians watching this... Notice how he calls himself out on his mistake? That's how he became the tech he is. Stay humble, there's always more to learn.
Well done for putting this video up Stephanos, it is a credit to you. Most tuning houses, at least the known ones, would absolutely avoid doing that, as it does happen all the time. In general I like your work as it is a quality one. As I've seen comments on pre-ignition, pre-ignition does not happen because of the spark plug, it happens because of hot spots, and the mixture pre-ignites before the spark plug fires. The dings due to the porcelain part falling off can cause pre-ignition, but Stephanos theory of cracking the porcelain while gaping them it is not the case. The plug having the porcelain already lightly cracked, tiny hair crack, by dropping the case of the plugs i.e on the ground while shipping it from the manufacturer/merchant to the end user is more of the case, as it does happen. The porcelain, white part, of a spark plug can also crack and brake off if the spark plug is faulty by the manufacturer during normal operation without any detonation present, very high egts etc. Also pistons do not get burnt, they crank, chip and break. A piston is constantly into combustion with very high temps and cylinder pressures, what people see on the crown of a damaged piston/rings is burnt oil.
much respect. im currently going to school for heavy duty mechanics and just finished up the section on engines. this was extremely useful andi was able to connect a lot of the dots on some things i was wondering about.
The fact that you put so much effort into these videos to teach us and show us even your failures is a breathe of fresh air there’s a reason I like you so much
Much love man
Done the same to my subaru when i was younger. Melted straight through the piston. The little end of the conrod had melted piston material sprayed on it like melted candle wax. Absolutely nuts.
I wish there was this kind of clarity in every kind of motorsport, but mainly motocross
Respect for showing the problem and even admitting it was probably your fault! I don’t think many people would have done that!
Thanks for taking the time to make this steph! I always enjoy your videos and watch them over and over especially these kinds. Best on UA-cam sir!
I really appreciate your upfront honesty and teaching tone on every single topic ,thank you for making this videos!
What a run on 3 cylinders. Fantastic team effort and these videos are so important to the motorsports communities.
The knowledge that is in these videos is amazing, and such an awesome thing to see.
Papadakis is the MAN.
The way you explain things are so easy to understand. Thank you for the informative videos.
Awesome video. So much detail with simple, effective editing. Such a cool thing to see coming from a dealership service background.
His personal power comes from his knowledge and humility, not some bullshit macho thing. A pleasure to listen to a true master
This is the second one of your videos I have watched, and I just want to say, I have huge respect for your talent, and your integrity. It is obvious why you are so successful. Thanks for the view into your work.
Seriously some of the best engine builder content on UA-cam, keep it coming!
Thanks for explaining in a language that a normal person can understand! And thanks for even showing what happened!
Great job to you Papadakis racing team and Stephan for making this video it takes a mature and special team to show it's failures. It's hard to blow an engine but it's part of the sport and you guy's are brave enough to show it to us. I hope you guy's can fix it or replace it soon and keep fighting this season.💪💪💪
Great video, respect that you exposed the problems and explained the process throughout.. I've followed your car in formula D, and saw your teardown, and now I need to change my spark plug gapping techniques too, thanks Stephan!
Hey Stephan; amazing content man. Keep the great work up. BTW I’ve got major respect for you dude due to this video. You’re showing the world that motor sports does involve hiccups and shit does go wrong but showing it publicly on you UA-cam for the world to see takes some balls. Major respect..
Literally the coolest dude in the tuning game. Pulls no punches. My favorite new channel.
Happens bro. Love the work
Awesome look behind the scenes! Thanks for sharing. I know you guys will be back better than ever for FD Orlando and beyond!
Amazing the honesty and integrity from yourself there .Trust worthy guy / company !
Just started binge watching your Supra videos, but this video right here made me a subscriber. Greatly appreciate your content. 🙏
Thank you for opening up your Your shop and your race team to show us the real life world of racing... We love to get inside of what really goes on these race teams... Everyone else keeps it a secret for some reason... It just makes you guys look Really down-to-earth and all about your fans... Think you again and keep posting awesome videos like this...
hey steph, thanks so much for doing these videos. i think its great that you put these out there whether its good or bad. great to see what happens during different scenarios of engine use
Uncovering the mystery as to why an engine blew up. What an awesome video.
I don’t think you should be shy about sharing the occasional failure. You guys are one of the few/only running a completely unique program that isn’t a v8/jz. Shit is bound to hit the fan in uncharted territory. The knowledge shared could definitely benefit someone in the future.
I appreciate how educational these videos are, also it's nice seeing these fantastic pieces of engineering being broken down and analysed for R&D purposes.
The only reason he would absolutely expose himself like this is because he knows he’ll learn from this mistake, and improve, and his clients know that. He’s great.
Very well put! Such a humble dude. We all learn from mistakes at every level in this game. Love this channel !
If you don't break stuff in motorsport, you are not pushing the limits. It's part of the game, the dance on the fine line between genius and madness, the line between greatness and destruction.
Love the openess and the honesty. Learning a lot. Keep it coming
I'm just getting into this whole car scene.. and you got to be the best teacher I've ever seen!! You were born engines and performance!! I Ty
Just found this channel and binged watched your videos. Love your channel, keep em coming.
Dude. This is by far the best channel for REALLY learning about cars. I've been involved with a formula racing team as a mechanic and they could learn some things from you. Deep knoledge here. Thank you very much for the effort of sharing it.
Great video! The best on youtube when it comes to engine builds and tear downs!
Such great videos that explain so well the parts of an engine, how they work, are put together, etc. Awesome!
Keep these videos coming. They are always so good and informative. Keep them without fluff and music like you are too!
You are a perfect example of how to do it right my dude. Keep doing what you're doing! I love these videos, I share them all with my piston head mates.
Awesome video, really cool how you're not hiding anything really, owning up to the problems that inevitably happen in motorsports
Steven, you are a very knowledgeable dude. Congrats on your technicality on all of your explanations about your car.
Super informative! Thank you for putting the effort into bringing these videos out! I look forward to each one you guys put out
Great video. One thing to mention is that pre ignition and detonation are often confused as the same thing, but that is incorrect. To fully understand these terms, one has to understand the combustion process. Combustion is not an explosion but a controlled burn beginning at the spark from the spark plug. With the spark plug in the center of the head, a flame front is created from the center burning concentrically to the edges of the cylinder, much like a forest fire. As this flame front moves, the combustion gas pressure and temperature increase, causing the piston to move down. This downward movement increases the chamber volume, acting to relieve cylinder pressure and temperature. While the fuel is still burning, if the piston is not moving fast enough to control the pressure and temperature, the cylinder pressure and temperature can rise enough to cause the remaining fuel to spontaneously combust. This creates a high pressure shock wave, (much like hitting the top of the piston with a hammer) causing severe damage to the piston. This spontaneous combustion is called detonation. Detonation can be caused by a variety of things, one being pre ignition. Pre ignition is caused by hot spots in the combustion chamber. These can be carbon deposits or as in this case, raised points of aluminum caused by porcelain chunks bouncing against and denting the top of the piston. These raised points of aluminum cannot dissipate the heat as fast as the smooth flat surface and begin to get hot enough to act as a second ignition source. Now you have two flame fronts burning simultaneously, causing the fuel charge to burn in half the time. Since the piston is not moving twice as fast to relieve the quickly rising pressure, the pressure and temperature rise to the point of detonation. So, the bottom line is that pre ignition leads to detonation. Detonation is usually caused by other reasons such as too much timing advance, which causes the fuel charge to reach the critical detonation temperature before the piston reaches top dead center. It can also be caused by using fuel with a low octane level. Low octane fuel burns faster than higher octane fuel, therefore reaching the critical detonation temperature much earlier in the combustion cycle.
That video is just perfection! First up he explains what went wrong with the engine in a nice and easy way and after that he blesses us with a nice clip of Formula DRIFT and his teams car. Well balanced vid, keep up the work!
Thank you for sharing the not-so-good sides of racing as well as the good ones! You have my respect for owning it and even suggesting the theory of the dinged sparkplug.
I'm a fan following Fredric into your team. Stayed because of quality content with no bs and hype. Keep doing that. Please and thank you 😉
I love these videos. mad props for owning it! Keep up the good work :)
Hands down the best teardown engine videos! Dayuuuum the knowledge while the disassembly
My favorite race team since reading about you guys in Tuner and other magazines back in the early 2000's. I love the simple explanation during break down and reassembly that you cover. Major respect for how you guys show what other race teams are either too afraid or ashamed to with failure parts, engines, transmissions,etc. Great videos👍👍👍👍👍👍.
Don't stop with your vids ! you know a lot about engines and mechanics. thank you for sharing your knowlegd. From Portugal
I love your channel, very down to earth with explanations and videos and not scared of failure. I appreciate the time taken to make this video as it saps aware time doing diagnostics and repairs
I absolutely love these tear down vids because you honestly learn so much more about engines from how they fail than you do from assembling them!
Love your videos. Thanks for taking the time to do them! Legend!
With every video I see I have more respect for You and Your team but also I'm more and more invested into technical aspect of this sport. I hope You'll continue with videos like this one. It's very educational and yet entertaining. Thanks Steph!
I have just officially became addicted to this channel...! :) keeps me wanting to see more of your vid`s . keep it up 👍
Thanks so much for the video and putting yourselves out there for the entertainment and education of others! Love Toyota!
Hands down the most comprehensive and coherent channel relating to race engines... Love this shit!
Another really great video🤘🏼. I’m really digging how open you are about your guys his program
thanks for talking about this sensible subject, effectively not too many teams talk about these kind of problems!! great vid
I fucking love this shit. I love the transparency. It's rare to get a look behind the scenes.
Great analysis! 👍🏼 Almost forensic. I love your videos, greetings from Argentina
What a great analysis. Super informative and educational. Hopefully this will inspire some kids to get more into the technical aspects of their cars.
Absolutely Awesome! fantastic breakdown and diagnosis
TRUTH ! IL be your biggest fan!
Things not told. By a brain surgen.,by a cardiologist., tattoo artist., (mis spelling) BUT A MECHANIC to say.i beleive i done this. Just knocked me dwn. In MO.last 100yrs. No human made a mistake ! PROUD OF YOU !
Awesome video! Really cool to see you guys continue being so transparent. Also Kudos to Freddy for finishing that battle with awesome proximity as if nothing had happened!
Really like your attitude. Great channel and great learning experience for you and the viewer. Thank you.
Im a mechanical engineering major and want to get into motorsports after college. This is some of the best and informative content Ive ever come across
I do appreciate you sharing what can happen - and showing off that new spark plug gapping tool. I had not seen such before.
Thank you for showing us this. Great video. I’ll be watching every vid.
Great job 'owning it'. Appreciate the detail also. Very nicely designed engines, love the series. Thanks.
It's really cool how you were willing to do this video. I applaud it.
This was extremely helpful and appreciate you being so transparent about the failure!
Thanks for an honest evaluation of engine and possible cause of failure
So came here from Donuts channel. I just watched a few videos. I love how you break things down. I am a huge engineering nerd, and love that you dive into the details. Thank you!
So professional in everything he does.
I wast just starting to search for the clip of aasbo when you said it happened in round for, and then you included it at the end, smooth move! Loved the vid as always
Best UA-cam channel right here. Love this channel!
Respect for your honesty and sharing of knowledge. Thank you.
