This is easy actually, step one go flat out in 5th gear, step 2 drop her down into 1st. This gives you way more than 20k rpm!

These are the videos missing in tuner culture period. Easy to understand, captivating, explanation videos for everyone from beginners to the experienced to watch to grow and hone their knowledge without being overwhelmed or underwhelmed. Easy to say but hard to execute, masterful job once again!

As a huge Formula 1 fan, thanks for putting this video out.

These videos are a hidden gem in the car community. A lot of useful information packed together along with high production quality and great writing.

Dude, I don't know how you do it. You always manage to make great videos that are very informative.

One of the coolest way I’ve seen valve float be removed is how Ducati did it with their desmodromic valve where the cam opens and closes it. That’s how they can get such high revs. They also don’t use timing belts or chains it’s all done using gears, it’s a nightmare to work on but it’s amazing when it works.

A quick addition to your point at 6:30 - the cycle limits are exponential - meaning that if you pick a force or a lifetime/ cycle limit, you can optimize and decide if steel or aluminum is a better choice. This is why drag cars use aluminum conrods. They're treated as consumable, and don't have to survive for long races.

There is no better sound. That angelic 20K RPM screaming NA V10 of old F1. I get tears in my eyes.

Yeah, the 7200 rpm d16 on my '95 Honda civic coupe had me addicted to high rpm NA engines... in the manual if you shift at redline it never dropped out of VTEC

Your ability to explain the internals of an old-school HEMI and an F1 engine in equal levels of detail is incredible. More people should know about you.

As others have said, your videos are solid. Good animations, no clickbait, simple explanations. Good stuff. There's a gap in a lot of car modding UKposts content from what I've seen that explains the how and why for the moderately complex issues.

Can we take a moment to appreciate the production quality this series has been consistently improving!!! Love this channel more everytime I watched an "explained"

Another amazing video. I really enjoy your explanations and how detailed you get into topics. We all need more content like this. I live the old “watch this beast do a burnout” video but these technical videos that people are starting to make today are by far my favorite

That intro was great

I love your comparison of steel to aluminium in the crankshaft section. It was so well explained.

I understood most of these concepts prior to this video, but the visuals and the explanations are great to refresh. Quality content as always man, thank you

This video got me to understand why GM shortened the runners from the TPI setup to the LT1 setup and explains why the LT1 and all other engines afterward where so much better, but I will always love the look of a well maintained TPI engine

High revving engines are my bread and butter. I love how you went in depth on how it’s done and how even the common folk could do it (which a considerable amount of cash of course)

Great video! It's so good to finally see someone correctly addressing exhaust velocity not back pressure. Subbed.

By far one of the best creators. Very informative without running on with sensless information. Very clear speaking and choosing words nicely. Ive always watched you on tiktok. But just found you today on youtube. Will be one of my forever shows to watch. Keep it up man

Sad to not see a mention of the Honda CBR250RR from the 90s. 19,000rpm redline with rev limiter at 20,000rpm from a tiny 250cc inline 4. Each cylinder is just slightly bigger than a shotglass in volume with a 48.5x33.8mm bore and stroke. The bike makes a whopping 45hp, which is pretty impressive considering thats 180hp/L more than 30 years ago and the 1992 CBR900 only made 121Hp (135Hp/L)

You have to get more consistent with posting videos more frequently. You do a great job, so this is something I truly do look forward to.

Easily one of the best channels for enthusiasts. Thank you for all of your hard work.

Excellent video as always, this channel definitely needs a million+ subs. Easily one of the most clear and informative out there.

The voice, the music, the video is amazingly done. Thanks for the videos

Great Video 337, each one outdoes the last. Can't wait for the next one!

These videos are excellent. I love the way you are able to take a complex subject and present it in a way most people could understand.

Holy crap i didn't know there where engines that did go this far in RPM, this video is a really good one about this subject, great detail and incredible illustration, thanks for this one mate.

This guys voice is the Morgan Freedman of everything automotive I can’t get enough!

Hey 337 speed. Just gotta say that I truly love your vids… you entertain so greatly and inform in such an easy way that it’s like watching a masterpiece. Because your videos are that. A masterpiece 🫶

One of the only creators I watch every video. These are hands down the best automotive videos out there. I remember seeing your clips on Tik Tok a couple years back.

This man’s editing/production skills are incredible 😳. I don’t even know much about cars and this video made me want to

my civic hits 20k rpms easy

You are on a completely different level to EVERYONE! thank you so much for your hard work and wish you all success in life ❤️ Never thought I'd learn so much!

I love these videos you break it down so easy to comprehend and I actually learn a lot like with your video on Gale Banks who I literally knew nothing about. Keep up the great work man love the videos!

The amount of detail and clear explanation in this is just 🙌🏿🙌🏿

Nice vid, before the V8 era BMWs P82 3.0 V10 ran to 19,200 on track and allegedly 20k on the dyno, they also use variable inlet length systems to optimise the torque curve at all RPMs, and the drive train is gear driven from the crank rather than using a belt, naturally aspirated F1 engines are an absolute work of art! I know the reasons for going turbo and hybrid etc but for me its a shame, I miss the raw noise of a proper high RPM V10

The ideal bore to stroke ratio depends on the fuel you're using, different fuels burn at different speeds so getting a combo that favors each other is critical to make good power. The reason pro stock engines have a lower bore/stroke ratio is not just because 'they don't need to survive as long'

I love watching your vids, i can sit there and just feed off all the information your provide, keep it up and never change!👍👍👍👍👍

This was a really cool video, I’ve been curious about the f1 and motogp drivetrains for a little bit and this was a wonderful introduction to the base differences of what sets them apart. One thing I noticed that I don’t believe was mentioned that I learned in a Rob Dham vid, from what I understand, the drivetrain tolerances are so tight that you need to preheat the motor prior to firing it up, and if it sits for more than 6 months(?) it will need to be disassembled and gone through. The throttlebody/inlet is fascinating as it is brilliant, on his cosworth (bought them for around 16k$ used) essentially there are 2 banks where a channel is made prior to the intake side on the cylinderhead that’s essentially a tube cutting across before the injectors/valves, in it a machined cylinder with 4 channels running into the head for the bank ported to allow air through, as the whole cylinder rotates to either cut off or flow or WOT. Genious for the simplicity and reliability.

You make a point at the end where you explain that going for high rpms isn’t worth it due to being able to make more power using forced induction ect, but I personally believe high rpm naturally aspirated engines are better to drive in my opinion and experience. On a side note I would love to see a video covering WRC engines. They’re completely different from any other racing engine. Simply marvels of engineering.

Wow, let's admire how much work does it take to make a video that spits so much knowledge per minute and the fact that it is available for free. The 2020's suck but at least there is still some good shit around

This channel has stepped up so much in quality it's crazy.

Ahh I was waiting for F1 videos from you and I'm not disappointed always perfect quality you deserve more fame man!

How do you make this awesome animations? Plus your graphic design is quite impressive.

When I read 20k rpms i figured you were reffering to the 90s 250cc 4 cylinder motorcycles. Which would be another great story. And while forced induction solves many problems you end up with more moving parts and weight.

I just want to say that you have the absolute best engineering and enthusiast videos. I was wondering if you could make a video on variable valve lift and variable valve timing. if you could focus on variable valve lift the most that would be great. Thank you for all the amazing videos.

your videos dont get enough credit. This is the part of Cars/ Engines i love! the actual tech of whats going on

Still building my 10k + RPM, LY6. 2 YEARS later, crank is just laying there 😅

Great video as always, thoroughly enjoyed it 337! I was wondering, based off your amazing animation and storytelling skills, if you could do a "Seconds from disaster" style video, starting off from some real footage of a engine blowing up, and then based off the investigation of what went wrong to explain in great detail the last few miliseconds of the engine's life, kinda how they had that scene in Cernobyl when detailing hownit got to the reactor core exploding. Thanks!

The fact that you are using assetto corsa (or not lol) and this channel is pumping so much info how the internals of a car work, I can certainly say you earned a subscriber. Keep it up :)

Although the rotating mass is very important the friction is a huge challenge. My friend worked on these engines and no shell bearings were used in the rods, just coated surfaces.

I'm a simple guy, I see a LS7, I hit like.

When comparing F1 engines to NHRA Top fuel engines with respect to piston speeds, there is one other factor I didn't hear mentioned. F1 engines use gasoline, and Top fuel dragsters use nitromethane. Nitromethane has a slightly faster flame propagation speed than gasoline, and this allows for a higher piston velocity, since the piston can move faster before it outpaces the flame front.

i love "rapid unscheduled dismantling of the engine" and i'm going to say it a lot more now

these animations are one of the best ive ever seen

Ever heard of the 90's 250cc inline 4 reaching 19.000 rpm ? The cbr mc22 and zxr250 do that, stock.(using a gear driven distribution for the cbr, but the zxr's distribution is chain driven). They officially did 45hp (180hp/L), but the cbr has been seen over 50hp (200 hp/L) on dynos (I myself have a 250cc 4 banger, a gsx250s katana, reaching up to 16k rpm for 40hp (at 13.5k rpm))

Thank you for the video and the effort. Very interesting. If you really want to reach extremely high engine speeds, you have to use electric motors (100k-rpm possible). And people who miss the deafening noise of combustion engines can certainly add a sound generator.

this was a masterpiece!!! excellent job!!!! loved every minute of it!!

Man, I love these videos, so educational, so soothing with the music. Thanks for the upload.

The Shitsuma goes way faster

Fun fact: F1 V10 used variable intake trumpets at low rpms they were extended and at high they were shortened

Great work, really informative and well structured 🔥

Top notch brother. I appreciate the overtime you obviously put in to make these videos.

Another great example of a technical approach to breaking down speed. 👍🏾👍🏾

Outstanding explination,great ideas,useful information. I can confidently say your videos are perfection

Y'all are the Absolute Kings of this regarding the Serious and Educated Enthusiast!! So many enthusiasts have no idea about the subject matter covered in this video; but for those of us that do, we greatly appreciate it! No one is Fucking with y'all, Salute!! 😎

I used to avoid this channel for some reason but this video specifically is getting my mental juices flowing. Thank you

Unexpectedly got the best explanation I’ve ever heard for torque v hp as a 10 second aside in this video.

As always, great, very informative video! Thanks.

This was fascinating and concise explanation of how these engines work

No nonsense straight to the point with an excellent delivery, visually and verbally.

Very nicely put I appreciate your videos , the exhaust one was very informative as well. To me it was more informative I never pictured the pulse waves the way you illustrated them. It answered a long partly unknown answer of why you exhaust is so important other then simply vapor removal!

AWESOME ! Also valve open time could be steered by electric coils like Multiair from FIAT and Koenigseg . Also interesting way to throw away springs from cam is desmodronic system from Ducati.

Absolutely fantastic work from this channel once again

Another superbly informative video, can't wait for the next one!

Gonna get ahead and say thanks for the content.

Love these videos!!! Best narrator out for cars right now!!!!! 🔥🔥

This is why older F1 cars sounded so much better. Also Honda, Kawasaki, Yamaha and Suzuki did this in the early 90s with 250cc bikes all going to around 20k RPM and running for years

The engineering knowledge in these videos is far beyond any other car channel on youtube.

Thank you for you're knowledge packed videos 🎉❤

These videos are awesome, I’ve learned so much on mechanical engineering in general that works for my ADHD brain. Thank you and never stop making videos like this

I'm still fascinated by the quality of your videos. Well done!

Well done sir... well done. Keep em coming.

Holy shit this is one of the best videos I've ever seen on youtube. Exceptional production values and the explanations were spot on.

It should also be mentioned that F1 NA engines used injectors positioned above the throttle bodies to take advantage of the charge cooling effect when the fuel enters the low pressure zone in the intake runners. They also used variation in fuel pressure rather than injector pulse to supply fuel at those high RPM's

E=mc^2 is a good basic measure, seeing as there is a max energy output before it breaks. The mass needs to drop or the speed at which it runs at max rpm.

As a driver of a rotary powered car and a tuned 2-stroke bike that goes way over 10k rpm I can tell you that turbos and superchargers are nice, but there simply is nothing that compares to the feeling and the sound of a wide powerband unfolding with increasing rpm. 🙌

Just wanted to give you a shout-out. Your content is incredibly well done. I started watching with the supercharged mustang video.

337 you did an outstanding job on this video , I loved watching it being a Formula 1 fan and also an NHRA pro stock fan . ( you 337 ) did A really did a good job of explaining what How reciprocating weight has an effect on RPM , and How YOU Explained this on A pro stock engine considering their size these 500 CID they really do REV very high for the CID of these ENGINES is truly Amazing in itself, and I am glad you put in ( this type and size ) During this video was outstanding you did a wonderful job thank you . 😊

This was an amazing video. About to binge all your content lol

I've had over square and under square turbo 6 cylinder engines with similar hp and both are fun in their own way even though they work a lot different! They were RB20det RB25det and Aussie Barra

Appreciate the effort u put into your videos bro theses are extremely entertaining 😊😊

The 4 biggest things that allowed F1 cars to rev so high is 1: The engines have no fly wheels, so the engine was freely rev with out any drag on the engine. 2: the internal engine components are made as light as possible whilst maximising strength, like pistons made out of beryllium and titanium con-rods and sodium filled valves or ceramic valves. 3: The engine timing advance and hydraulic lifters on the heads and some other valve timing internals, tuned plenums and exhaust pressure management because the faster you can get rid of the spent exhaust gasses the faster you can get more fresh gases in the engine. 4: This one along with no heavy fly wheel is very important to the high revving F1 engine and that’s the short stroke piston, however todays engines because they are turbo charged (which is better than super charging because there’s no parasitic loss of power on the engine because it’s not driven off the crank shaft with belts and pulleys like a super charger is which saps power from the engine to drive the super charger and a turbo uses spent exhaust gases so there’s no loss of power from off the engine with turbo chargers so you get more power) going back to where I left off above - todays turbo charged F1 engines have a lower compression ratio due to turbo charging, so to try and off set this a little you need a longer piston stroke that allows more air and fuel for a turbo charged engine this bumps up the compression ratio a little but the longer stroke means the RPM is not as high. Whilst this is vastly simplified, I hope it gives someone a little bit of an idea or to understand the engineering that goes into F1 engines to make them so compact light and powerful from a V6 - 1.6 litre engine (62.9 Cubic Inches) that puts out 1,050 Horse Power. Crazy machines at the pinnacle of motorsport.

Wow, Video well made, well researched and very well explained. Thanx a lot, you gys are an inspiration

I’ve been waiting on another engine vid.. I’m hooked 🤣🤣

That S2000 brought me back. I would have loved to have an AP1 (would settle for an AP2 though these days with prices of S2000's). Amazing cars.

In your discussion on valve operation you didn't mention the positive opening and closing of valves (desmodromic operation) used with success by the early Mercedes Benz race cars and apparently still in use by Ducati.

This was very informative. Thanks.

What a great video. Thank you!!
