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
Lol it’s good to know that even papadakis drops stuff on the ground and has to crawl around to find it.
At least his floors are white so they're easy to find
And there’s the reason for having a clean workshop ;)
His workshop is way cleaner them my living room
Lol!
Lol
"AEM was nice enough to flow me a couple of these pumps"
punny
I don't care what's next. Just keep 'em coming! I love getting down in these weeds, Thanks for taking us along!
Great Video ! i really liked it and it was so cool to watch whats going on inside of the fuel pumps. Thanks a lot for that and take care!
Clean shop for sure
needed more explanations about how the fuel is actually pumped out
Just go on Wikipedia and look up positive displacement pump. It will give an in-depth explanation
Interesting. Watched/liked
nice presentation!
Tear down all things please!
Thx
can you do a teardown of a stock 2ar-fe engine plzzz
Tear down the new brushless TI-Automotive BKS1000
MyDream shop! I can eat off those floors
No disassembly is complete without a search for the jeeesus clip
@freezeme360 a personal favourite is the hell spring. Small enough to to hide in shop dust. Large enough to fly across the room and land, apparently, in another dimension.
Rumour has it you can place a 10mm socket under your pillow and a fairy will find it for you overnight
Jeezless!
@@tojiroh you'll find it when you need a 9mm or 11mm
@freezeme360 maybe you’ve got imperial fairies. Try a 7/16 or 13/32
"Want to see me teardown other stuff?"
Uh yes, basically anything. I'll watch.
agreed, open up anything and everything engine-related. Maybe a power steering pump or AC compressor next? Different variable valve timing setups?
Yeah, I want to see everything. My suggestion is maybe an AC compressor or a electric bypass exhaust?
Yaaasss, tear down all the things
Mabe the electric power steering
Tear down the newer brushless pumps or dry sump oil pump
@Peterbjorck posted a video on dry sump pump just a few hours ago. Very educational videos just like this one :)
Look back a year he's torn down a dry sump system
I appreciate that papi papa isn't just a big wig in an office but actually knows the ins and outs of all his cars.
I think he's the exact opposite: totally involved with every aspect of his cars' development. Great knowledge and a great teacher.
2 fuel pumps were harmed in the making of this educational documentary.
Nope...they were...um...er...hmmm...sacrificed at the "Alter of Knowledge"...
A ABS unit would be interesting :)
That i would love to see!
To the top good Sir!
a workshop floor so clean you can find a c-clip on the floor easily after it pings off across the room.... niiiice!
Didnt find a 10mm while looking for that e clip did you?
Lol
Pap works on BMWs now... No 10mm needed. 😁
This is extraordinarily detailed and broken down for us to easily understand. Thank you for sharing this with us.
The entire electric motor is sorrounded by fuel
Me: 👁👄👁
This shocked me as well. But it makes sense.
Shocked me a bit when I learned about it a few years ago. Honda recently had an issue where, in the pursuit of energy efficiency, they ran the fuel pump at variable speeds according to flow need. With some fuels this would cause sulphur build up in the motor and then pump failure. So a software fix was put out to increase the minimum speed.
further, fuel carries away heat from the pump motor as well as lubricate and I assume clean it from commutator dust.
LMAO 6:44 Literally me every time I install valve springs and a retainer pops out
That was me in kitchen yesterday assembling my heads😅
That’s a clean floor to be able to find tiny e-clip
I dare say he has next level ocd cause i've seen some clean work areas but nothing like him
@@nuvisionprinting definitely , the man has a dedicated room just for building his engines
@@nikogambino2723 i've also seen dedicated engine rooms that aren't quite at the level of papadakis!
the gudgeon pin retainer clip that i lost on the floor and is preventing me from finishing my engine rebuild be like.
The fuel injector, small cc to large cc.
Came here to say this, maybe also include port vs direct injectors
More teardowns!!!
I'll never sleep again from so many great youtube creators always posting lol
Who else you watch? I'm bored lol
I thought I was the only weirdo up at 2am every night watching TH-cam lmao 🤣😂
@@imacaryay7628 applied science just uploaded
Yeah those e-clips like to fly off into the ether in my shop LOOOL
The end of the video is a classic when you are dealing with screws and that kind of clips, such a relief when you find them 😂
That was interesting, thanks
I didn't know fule ran into the live wires.
I would love to know how a power steering rack works.
I wish you would have shown how the bearings and everything meshed in the first pump a little better though
6:45 lol, I've been there too... but my garage floor is nowhere near as clean, took quite a while to find it :D
great video, I love how you go into details because many of us here are a little more than amateurs and as myself there are plenty of engineers I wish you tear down a high end turbo+waste gate and expose the technologies involved
Tear down a rotary engine, heard it's been done a few times 😂
Rob dahm got you covered on that 😂
@rob damn you know I just playin homie, don't rock up to mine with that 26b at 4am
Cheap vs expensive alternators and batteries. How trans brakes work?
It would be interesting to see a teardown of a shock absorber/damper
thats real teaching who needs vocational school when you got papadakis and youtube
There's no substitute for hands-on instruction.
Love seeing things torn apart in ways you can actually see how they work! Thanks for the description during disassembly too. More please!
4:15 see guys don't throw away your old pumps!! There are quarters inside you can get a little money back from 'em.
Seems like a motor starter without magnetic switch
I love the way you explain. Txs for the video.
Tear down everything! Love seeing tear down videos by experts.
Literally watch every video you release within minutes 🤣
You mention that the fuel can flow through the motor because it's not as conductive as water, but brushed motors work when in regular water.
they also rust and corrode when in regular water.
But the efficiency goes down proportionally with how much ionic material is in the water. Once you hit sea water levels of conductive salts you basically have a "motor/kettle hybrid" device.
Thanks for sharing Stephan, I would have thought AEM used a brushless motor but guess the engineers have their reasons. Also like your teardown video's keep em' coming!
Very interesting video. Thank you
these youtube channels really provide more education than my "institute"
Love teardowns of anything automotive oriented thanks for all the awesome content.
Would love to see a shop tour. Tools, cabinets, etc
I have a problem with intank pump I want to use for inline pump. The bottom of pump has a large intake hole. There's also a very small hole in bottom plastic that is pressurized when pump runs. If I plug small hole pump fails and no fuel flow. Small hole open pump works but fuel comes out small hole & normal outlet on top. Obviously can't have fuel spraying all over from small hole. Is there a way to use it as an inline without spraying all over?
I am developing a jet engine. Now you need to create a control device and therefore you need to create a lightweight and smaller (Out Diameter 40mm) fuel pump.
If you have a suitable pump for me in your country, will you recommend a fuel pump or you can sell it after purchase? The fuel amount should be able to pump 3 LPM at 5 to 7 bar, and if there is no gear pump or no gear pump, it is also good for the same method as the pump of this image. Motor is better if the motor is BLDC.
Thank you.
Would you...could you...show the difference between bushed turbos vs bearing turbos...? Two stage vs single stage... Tandem vs single... Wash, rinse, repeat...
Your videos are absolutely amazing: Short and to the point and yet I always learn something. Thank you so much!
Just watching your videos you've taken away the fear of working cars being so complex. These videos make me want to learn more and do more with my own car.
Stephan.....
You could tear down a seat belt system and I (we) would watch and listen! This has been up for a day and over 50k likes and 300 comments....about fuel pumps!
So yes....more!
Do a cooling system.....racing vs oem.
Electrical system....racing vs oem as well.
Don't assume everything isn't important. There's tons of us that don't do this everyday. Even veterans, if they're smart, would listem possibly learning something new.
Loved the video definitely want more of this!
Hard out! Teardowns, tech insights, bring it on Stephan
Maybe a DSG gearbox teardown, or other automatic transmission? Or CVT gearbox? Centrifugal supercharger? Roots supercharger?
Have you heard about "The Secret Horsepower Race - Western Front Fighter Engine Development" by Calum E. Douglas? It's about aero engines, but it's written by an F1 engineer working for Mercedes team. I like the book as much as I like your videos.
Notes: A lot of these aftermarket pumps are made with electric motors that have carbon brushes on them just like your electric power tools. Often times the fuel itself cools the pump and is in direct contact with the electricity of the pump. It doesn't make the gasoline catch fire because the hydrocarbons are poor conductors and there's not enough oxygen in the fuel pump anyway. (What about if the pump were partially ran dry? Not sure.) "Reactive Turbine pumps" can be damaged in less than a minute if ran dry. Sometimes the magnets for the electric motor is part of the casing and therefore nonremovable.
In 1994 I had a 16v Golf 2 which ran a Bosch high pressure pump like the one you opened. A fitter and Turner friend and I opened it up and serviced it.......car ran another 180 000 km on it. He started a successful business doing repairs!!!!
Hi! I would like to ask if you could put an external fuel pump on a 2000 model Ford Expedition 4.6L? I'm having frequent issues with the fuel pump and now labor is expensive and also the price of the assembly itself is quite high. Thank you for your opinion!
You're a super knowledgeable man, Mr Papadakis, with an excellent, relaxed presentation style that comes with that knowledge. I enjoy all of your vids, even though I don't need to know any of what you show me as I don't have the £££ to modify or even buy a sweet car. Definitely interesting though. Totally subbed.
Good to know, look so simple, Do an alternator next 😜
Thanx for all the awesome tech/info Stephan....always interesting to check out your videos...
what is difference on these pumps versus original bosch 044 when it comes ethanol/methanol resistance? I bough similar pump to that aem from another brand. Either it was really ethanol resistant, or just bad pump, but it lasted only few months of driving (85% ethanol).
Great educational video, love the breakdown. Just speak a little slower.
It would be nice to see a video on how and why fuel pumps deliver such a range of volume at a min pressure of 43psi, and can, fuel pumps outsupply the ability of a fuel pressure regulator.
I've always been curious about this. I know how various fluid pumps work but have never seen their disassembly and dissection. Tearing down other stuff... how about a few different fuel injectors? Or maybe some differentials? Thank you!
Ahhh so I blew my is250 fuel pump... Ethenol suks, I had like 2 gallons sitting for 2 weeks and it evap, now my IS doesn't start
Suscribed..., Hyy the VinDiesel family business 😂😂🤭,, i juss playN👊🤖♥️
Just curious why you prefer the AEM external pumps to the internal pumps? I was running that exact AEM external pump but a 340gph model but I designed a new fuel tank and had it built and will be going internal for a quieter pump that lasts longer that is still good up to 800hp.
Do you know if AEM makes a replacement E85 pump for my 1997 BMW motorcycle? Thanks
Tear apart a break master cylinder! Or a shock! Love your videos, thanks for the amazing descriptions and awesome quality.
Great video, please more tear downs. How about showing how some big relays work, an old school air flow meter with flap, versus hot wire. Or maybe a fuel injector and high pressure diesel pump. Thanks for taking the time>👍👍🇬🇧🇬🇧🇬🇧
Pumps are actually very fascinating. I kind of wondered how Locus fuel treatment would quiet a fuel pump that would make noise when I was over a 100 degrees. Now I know its because the entire motor is submerged in fuel.
Love your videos bro! Can you do a BRUSHLESS Fuel pump next (the latest and greatest style of pump)?
Is fuel really in contact with the motor windings and brushes and bearings? That’s actually mindblowing to me. What happens to the dust from the brushes?
Open up a fuel injector ,
Drysump oil pump ,
(Fuel injector will have a magnetic actuator and a nozzle , but want to see how the CC is measured)
Mr. Papadakis, could you and your team explain in the next video how ECU works? Your content is top-notch!
Stephan, Can you describe why some engines use 2 spark plugs per Cylinder (i.e. e-320 Mercedes Benz)
I always press the like button at the beginning because I know I will always be satisfied by the rich content. Thank you for the knowledge Papadakis!
The fuel flows over the armature. Fuel is non-conductive. That’s amazing - I literally had no idea.
The spring went springysproingy. This is considered normal, but very obnoxious, behavior for a spring. They also have a tendency to find the most obscure hiding place once they're done with their shenanigans.
Great video
Once I melted my fuel pomp bracket because I run on 1/4 tank for months and it wasn't enaugh fuel to cool down the pomp.
So realistically, if the fuel pump manufacturers weren't greedy, a lot of dead fuel pumps could be repaired just by replacing the brushes. 🙄
LEarning is fun. Never thought I would say that LOL Awesome video take anything apart
I feel like such a dumbarse. I completely understand the concept of hydrocarbon fuels being electrically non-conductive and the fact that no ignition can occur without the presence of air within the proper ratios, but I just... never fully realised that fuel flows through/past the motor windings and brushes, despite the placement of the inlet/outlet fittings and the overall design making that rather obvious. Cheers from Australia Stephan!
I just saw 2 examples of why fuel pumps are not serviceable for the average car guy, i being the average car guy would not have found that clip on my shop floor and would have had to buy another pump anyway so……i will just buy a spare and toss the other one when it fails.
Please do injectors
Or anything of that sort of mechanism in new engines
I really like the way you explain... it’s very simple and persist
It's disappointing to see that these use brushes instead of BLDC motors. BLDCs are amazing and offer so much more control precision, not to mention reliability. Once those brushes are worn, so is the entire fuel pump.
Maybe prices at fuel pumps are the biggest scam in the world, because it's nothing compicate inside. Simle electromotor.
Are the AEM pumps better than OEM ones? Thinking of the VW Passat W8 application.
I have a question can i change 6d24 engine mitsubushi fuel pump for 6d22 engine
I remember racing 10th scale RC and we would use motors with different winds around the armature for change in torque/hp. Does that come into play with fuel pumps as well?
Great demo. silly these aren't serviceable though. Very wasteful.
A week before I had a stuck fuel pump like the second one you showed from a Honda 225hp v6 outboard that was sitting for up to 8 years and just replaced it. i was wondering what was in it so now I know. To bad they cannot be serviced.
I have an AEM 044 style pump that sounds like it’s chewing rocks. I’d love to send it over to see what is actually making that noise now that I’ve seen what the inside looks like.
i think a teardown of different types of differentials would be cool. the disk, the cone, the torsion.
or a teardown of different types of transmission. typical 5-speed, dog box, and most importantly show the power flow inside the transmission.
I would just love to see more videos from you maybe going over your race weekend each race . Great VIDEOS
