Coming from a polymer/material scientist, this is a great simplified explanation, love it! Only thing I can knock it for is the use of "silicone" vs "silicon," two VERY different things.

The only bummer was in the end ... he used completely different orientations on the pistons to compare their relative strengths. :-/

I am a materials scientist with a PhD. Most CZcams videos you watch these days are haphazardly prepared and are supported by superficial research efforts. This video, although not very deep in content, is absolutely flawless in explaining the engineering principles. I watch Donut as a comedy show but I also learn a great deal about cars etc. Thank you guys for your service to everybody who likes to learn more about engineering.
This is the same reason why diamond is so strong, while also being made of the same material your pencil led is. It's the alignment and structure of the carbon atoms that give the diamond its strength.
Not to mention, a pencil led is very dark while diamonds are shiny and somwhat transparent. They both are made of carbon but the atom arrangement changed a lot of properties.
Led ? I thought pencils where made with Graphite and diamond Made of carbon
@@alexalfonso100 indeed graphite is made of carbon.
And a single layer of carbon is called graphene, which has quite good capability of conducting electric current.

I'm in a material science class for my engineering degree right now and this makes more sense than my professor explaining grain structure.
Awesome job by the editing team this episode’s effects and transitions were really impressive along with the seamless way that clips are stitched together for jerbears characters. Very entertaining and informative at the same time.
JerBear is rapidly approaching James-level entertainment levels while still being the smartest of the hosts. Well done.

It's a toss up for me between him and James. Nolan is also really cool. Honestly all the Donut guys are cool, love this channel and love the Past Gas podcast.
@@RSpracticalshooting Yup they’re all great! Just particularly love Jeremiah and his way to get a point across and still be funny about it.
@@RSpracticalshooting Zach is also amazing. Every host is great on Donut
Zach is the best.
If you look closely at the forged piston at the end when it gets split open, you can see that the grain structure is a little different near the surface of the part. Since it's pressed into a die at high pressure, it forms a sort of crust on the outside that is very strong.
Grain structures are too fine to be seen by eye, particularly for a forged component. You mean the fracture surface of the split open piece relative to the point where it reaches the edge?
Mechanical engineer here, I love that Donut is taking concepts I had to learn in college and making it easy to digest. Materials Science is pretty dope, obviously.
Keep it up dudes
Awesome job on this video, Donut crew! Thank you for the opportunity to be involved 🤜🤛

Highest replay value episode so far. Thanks!
Im a diehard Mustang guy but I love everything about Jerry's Catfish, including the bitchin' CD trapper keeper. Thats a flashback to highschool in the mid 2000s for me.

People might wonder why the piston needs implants. Does the piston not think it's perfect just the way it is?

I love how much information you get out of these
Really informative mate, keep it goin
Have some forged JE Pistons going in my LTG Malibu next month so this was perfect timing!
Who builds and LTG Malibu? Lol. You race it, or?
@@joshuagibson2520 no but I did blow a ring on cyl 4. Compression tested at 75psi lololol. And the stock pistons are trash so I’m throwing some forged in. The FWD platform doesn’t have much potential but I’m tuned, exhaust, intake and some other little things and it makes it pretty damn fun. The LTG camaro and ATS on the other hand are wild. Fastest LTGs are like a 10.5 and 11.2 in the quarter. The 11.2 camaro lives in the same town as me in Iowa.
@@ABurk2 hell yeah. When I was racing in the late 90s and early 2ks, you'd see an occasional built Beretta or other car you'd never expect to see. I kinda like the weird shit like that. I'm Fbody (camaro) for life, but let's face it. They're boring and everyone has one. Same with Foxbodys.
All cars can benefit from the upgrades you listed and also be a ton of fun. We don't all have to be running 10 and 11 second quarter miles to enjoy the hobby. I hope you get some enjoyment out of yours for years to come.
@@joshuagibson2520 that’s man I definitely will! I love a good sleeper🤘🏼 my previous car was a 97 Regal GS (SC 3800) and was so damn fun but slow as hell even with a run and intake. Even slower after I threw a rod!
I wish my teachers were this passionate and fun about the topics they were supposed to teach us at engineering school ..
Yea maybe I would have stayed in the program.
This was extremely informative, thanks! Great job!
Great video and excellent explanation. Keep it going guys!!!
DUDE HELL YEAH! That Twista CD was a staple in every CD book, ever.
Pistons are like the car equivalent of your heart's ventricles
That is a surprisingly good analogy
One of the best videos I've ever seen from you guys! BRAVO!
Very interesting. Can’t wait to forget half of this and rewatch this in a couple months as if I’ve never seen it👍
As a catfish owner myself, I was stoked to see a catfish so prominently featured in this episode!
nice video.. another benefit of forged pistons is that there is no cutting through the grains, all grains remain intact.. that is what makes them stronger, and that's also why tools like spanners and wrenches are made the same way.
Material science is one of the hardest subjects in engineering studies, but one of the most fascinating.. i really liked it when i was still in school...
Thanks for making this applicable educational material fun to learn. This info is great
Episodes keep getting better and better

what an educational and entertaining video. better than any teacher i’ve ever had at school i actually understand this stuff. good job donut 💪💪
Mr. Frizzle had me blankly staring at the screen for a lot longer than i would like to admit.
Everyone just got a metallurgy lesson. I work with customers who do this stuff everyday. Very cool stuff! Great video.
Very nice and useful episode 👌🏼👏🏼
very informative and entertaining at the same time..i love learning from you guys..mow powah baby
Okay Donut videos have officially reached the elite level. This was a masterpiece
I’m fairly certain I’ve seen Mr. Frizzle on “How to Catch a Predator”… lmao 😂🤣😂🤣
Agreed. On one of those Florida episodes lololol
Been subscribed to both channels for a long time! So cool to see them on the same video!
Cheers brother, I hope you teach students! Very good metallurgical discussions.
Mr.Frizzle is by far the best part. Lmfao
Do you believe in Jesus Christ?
I wish he had smashed the forged piston in the same orientation as the billet and cast piston so we could have a legitimate comparison. B2B although no longer what it once was is my favorite show on the internet. Well done folks.
Dang! alot of work got put into this video. Great job guys
Good video, explains some stuff well. I am a metallurgical engineer so I really appreciate it when people bring my expertise into the mainstream.
If you are really interested in learning more, definitely start looking into other explanations since these are super simplified.
this is the best donut episode i’ve ever seen
When Jeremiah hit his head with the soda can, I actually laughed out loud.
For me it was when he roasted nolan so fluidly
Your best video yet! Keep it up
I learned (kinda) some of this stuff in my intro to materials science class! Awesome work!
This ep had huge magic school bus vibes when he dived into the piston, but now for us adult car nerds
Question for Jeremiah: what would be stronger, a cast titanium piston or a forged iron one
titanium isnt good for pistons, thats why it isnt used
Forged because titanium isn’t great for pistons, they’ll crack. That’s why big turbo cars use steel exhausts instead of the prettyboy titanium stuff
@@savagetuner2404 and friction welding is also a thing
@@adrianolacerda3410 right my boy, I raised you so well. I was going for the quick 2 sec explanation but it’s always good to give some background info.
are you serious? My background is in knife making. The metallurgy is similar. You can have a knife that holds it's edge, is easy to sharpen or is chip resistant. Titanium is super flexy, (check out the BOW-TI bike, no pivots on the frame). It does well when flex is required, but is not "hard". A Ti piston would warp quickly. It is light, which would be good for piston mass, but it's springiness is detrimental to cylinder seal. Ever see a high quality knife BLADE made out of Ti? You can do the handles but even 1095 is a better steel for knives. Planes use Ti to save weight, but a jet engine doesn't operate the same way as an ICE. Forged steel (nobody uses iron in engines anymore). I don't know the thermal values of Ti, but you'd likely be letting fuel into the crankcase.
Metallurgy in a nutshell - job done! I did a materials engineering degree with automotive engineering about 15 years ago. You explained it so simplistically in 20 minutes, in what took a 6 week module to do.
You guys really stepped it up on this video. Nice job.
Your math for the number of power strokes per second is off by the number of banks of cylinders on the engine. if an engine is at 6000 rpm and there is a power stoke every other rotation, that’s 3000 power strokes per minute, but if there is a straight 6 with the firing order where there are 3 firing groups of cylinders, then each piston only has 1000 power strokes per minute or 16 strokes per second. That’s still amazing, but it’s not 50.
That's not true, 6000 rpm means that the crank rotates 6000 time per minute, and thus each piston completes 6000 strokes, or 3000 power strokes. The number of pistons does not effect the number of power strokes from a singular piston.
This video was such a godsend I’m rebuilding my engine and this answers so many questions
What kind of engine is it?

Fun fact that method of creating the billet stock is Called extrusion
Ah yes, silicone, the most underrated and misunderstood metallurgic component there is.
Keep up the great content, pronunciation aside. :)
7:39 caught it too. Common mistake to call silicon silicone
I thought I was the only one that caught that.
I was like I know I'm a computer engineer, but I don't think silicone is used to strengthen metal.
absolutely monstrous amounts of effort put into this video, it was great
You explained grains better than my manufacturing lecturer so thanks! I have complete understanding now
I'm a Sri Lankan and somehow this makes me happy
I'd be curious to see how sintered pistons would fit into this
Honestly, not great. No matter what kinda of sintering approach you take, you won't have as much fatigue resistance and very high creep. Sintering causes porosity in steels. This porosity is not equally distributed like in casting. Not to mention, sintering such complex part is much more complicated. Needs a lot of chemical and/or heat treatment to get the specs (eg. Tensile strenght) right. But even then, you'd have a pretty good chance your thermal expansion being much higher thanks to poures and very unevenly distributed. It's just cheaper, easier and stronger to go with even casting let alone Forging and Machining.
Dude, the editing skills are God level. What are you guys doing on YT! You guys deserve a show on Prime or Netflix.
These episodes just keep getting better
