Flatplane vs Crossplane V8 Engines - Which Is Best?
Вставка
- Опубліковано 29 жов 2024
- Flatplane vs Crossplane V8 engines. Foreign vs. domestic. What is a flatplane crankshaft? What is a crossplane crankshaft? These engines get their names from the design of the crankshaft, and have key distinct differences. Flatplane engines have the primary forces balanced out, so the crankshaft can be light and fast revving. Crossplane V8 engines have the secondary forces balanced out, making them very smooth with the addition of counterweights to balance out the primary forces.

NEW VIDEO EVERY WEDNESDAY! - Авто та транспорт
Cant believe that a channel this good exists
+urban kranjec So kind, thank you!
its the best
@@EngineeringExplained You're welcome
And this is an old video. Just keep digging through the videos. I've subbed and I've dug and backtracked. Believe it or not I have a leatherback automotive mechanics manual (not a fix it book but an engineering and MECHANICS of automotives book) and it goes into detail about crossplane and floatplane cranks. It was printed in 1946.
@@ShogunAutoworks What is the Name of this book, the publisher and author... I'd like to find a copy or reprint of it... Thx.
The more I learn about the balance and vibration problems in other engine types the more I love the inline 6.
right!
Natural puller too.
GM has one big one in their medium duty truck gas motor straight 6
I put fluid dampener on 5.9 cummins it it really smooth out should help my seals and bearings love straight 6
Need one on my drive shaft and my 92 cummins had one on the drive shaft coming out of transfer case it was first I have Sean that .😊
Just read about the C8 Z06 having a flatplane crank and was thinking Engineering Explained should do a video on it!
I also discovered this video as a result of the Z06 leak. Hopefully when Chevy makes an official Z06 announcement, EE will revisit the topic.
BRUH SAME
Chevrolet following Ford by 4 years, that's about right.
@@daleostrom3613 You will see 10,000 C8s before you will ever see a Ford GT on the road.
@@thomasmathew7305: Actually, all Shelby GT 350 Mustangs going back to 2015 have had the flat plane 5.2 liter, normally aspirated, 526 HP engine. That is 102 HP per liter. Best power of any normally aspirated production engine. Just the Facts.
Anyone else here after hearing about the C8 Z06?? Needed a refresher on crankshafts and knew the perfect place with a whiteboard
Almost all of your videos have "if you haven't already watched X video, you might want to watch prior to watching this"
I have to start watching all of your videos before I can finish watching all of your videos.
Diabolical. I salute you good sir.
Excellent video. I'm not sure if you're a teacher or a working engineer, but you would make a very good classroom instructor.
*polite clap*
Sir this is one of the best channels on youtube
Thank you for the time you invested to bring all these videos to us
Happy to hear it! Glad you enjoy the videos!
her is very sweet
Anybody come here after learning that the Corvette C8.R is using a flat plane crank?
I did - saw the video on the same youtube page
Yes!
LOLLLL first place I came after hearing the Vette news. 😎
Exactly what happened! Now I'm educated. This guy makes great videos with crystal clear explanations.
Same
I'd love to see a video on W12 engines, these are definitely my favorite explanation videos on UA-cam.
Discovering things that I didn't even know I didn't know about! Can't wait to see what else I don't know about cars in your future videos!
The Shelby GT350R is why im watching this video
🤣 me too
Lol me to
🤣 Same dude
Me too dude
Read my mind.
Cross-plane cranks give you tons of neck-snapping torque fun right off of idle at 1000rpm. My 2017 Corvette C7 also gives me 37 mpg on the fwy.
Yep, gotta love that firing order. Though Honda sounding V8s appeal to my inner rice tbh.
I'm sure this video's views have gone through the roof since the GT350's release. I know that's why I'm watching.
Facts 2023
Hey, I’m an aeronautical engineering student and I love cars but I don’t know much about them. Your videos have been very helpful to teach me about the mechanics and design behind cars and engines. Thanks!!
ALL HAIL THE V8!
Amen
V8 Akbar!
omg so going to hell for this.
Crossplane for the win
JustAnotherCarGuy except if it's a Ferrari engine
Flat-plane ftw !
would love to hear about exhaust scavenging, intakes, venturi effect, multiple valves, all that sorta shit! keep em coming dude! much love!
I've got videos on pretty much all those topics! :) Search my channel for each word. Performance exhaust (scavenging), diffuser (venturi), dohc vs sohc (valves), cold air intake (intake).
Nice spent 20mins reading on a website to find the difference between the two, no luck, you nailed it in the first minute 👍🏻
I really appreciate what you're doing here. Thanks for making these videos.
Very welcome, thanks for watching!
Thanks alot for speak clearly! My english is not so good but I understand 99% then I watch it twice to get 100%.
A couple of issues I have, cross plane cranks don't necessarily need a larger crankcase when comparing the 2 crank styles with identical strokes. Also, there are center weighted cross plane cranks that are lighter than normal production cranks, and still maintain the vibration reduction. The only real benefits to the flat plane are the points you made for exhaust scavenging, as well as intake wave tuning. But contrary to popular belief, they do not inherently rev any significant amount higher than what can be done with a cross plane.
I think people actually mean that the rev QUICKER when in Neutral. They associate quicker with higher.
any time i want to learn anything about engines; it always leads to this channel!
Cross planes also have the famous v8 burble
And the flat plane v8 has a disappointing four banger sound.
davidrobert2007 You mean a glorious wail ;)
davidrobert2007 idk what is disappointing with f1 sound?
The flat planes do sound, uh, rather pitiful.
I'm European so to me the famous V8 sound is a screaming super car rather than a burbling muscle car.
Don't care that crossplane V8s make less power, they sound so much better imo. Especially a pig-iron American V8 from the 60s / 70s ...best sound in the automotive world imo. And that's coming from a Brit lol.
Thank you for the first clear, simple explanation of this type of engine I've heard.
As an OLD mechanic I can say ,you REALLY know what you are talking about
Those are known as 90 degree and 180 degree cranks. I always default to original nomenclature whenever possible. "Tri-Wye" headers (different for each bank) eliminate the uneven scavenging with a 90 degree crank. They work great (and sound great) on my 440 Cubic Inch Chrysler big block.
The flat plane crank is just the beginning of engineering this type of engine. The cam shafts has to match the new firing order,the Ignition has to do the same. The introduction of balance shafts can mitigate the size of the crank throws. The only benefit is higher RPMs and possibly Horse Power. The thing to remember is if you change one thing like the crank or value timing. You have to change everything! That is why forced induction is so popular. Just need a step down in compression and either plumping the exhaust for a turbo or plumbing the intake flow for a super charger!
Might be cool to include an audio sample of the difference in how the two engines sound.
Excellent idea! 🙂
Just bought a GT350 and came to your video to understand the crank. Good info, thanks.
Wow I came here for infos on Flatplane vs. Crossplane, I had no idea we would go down into memory lane with Jason! 😍
I have a book on the Allison V-1710 V-12 from WWII. It has a page that talks about rotational imbalances that's quite enlightening. Allison engineers had to deal with THIRD-ORDER harmonics because of long shafts used to drive the overhead cams and engine accessories mounted on top of the engine. Included is an exploded view drawing showing the various imbalances and their vectors.
One of the best channels on UA-cam. No nonsense no hype. Just knowledge.
BRAVO!!!
If you have the time, can you please look into Nano engine oil technology. I know that there are oil additives which claim to bond to metal. Truth or myth? Thank you in advance.
He has the gift of explanation better than most. Nice work. Flat plane, FTW
Your videos on UA-cam are special, outstanding and really enjoyable to watch at the same time. Love them!
Being an engineer myself, I'd honestly say your channel is one of the very best out there.
As I totally love V8 engines, I like this one a lot for sure.
Keep up your work and style.
Thanks for the video! Ever since I heard the GT350 was going to have a Flat plane crank, I have been trying to find someone to explain it to me.
Great Video! I have GT350 thus wanted to learn more on the Flatplane crank thus your video was very helpful!
Awesome video man! Straight to the point, without over-complicating the concepts!
Subbed

I would love to see you do a video on Yamaha's new crossplane i4 used in the R1 and the crossplane i3 used in the FZ09/XSR900!
Convert to 2 cycle, poooet valve loop scavenged as you don’t have to cut ports into it
. Unkessyyou want too
@@jlo13800 It is a 4 stroke engine, not 2 stroke.
As well as the MT/FZ-10, 160hp out of 997cc is truly amazing considering it's price and simplicity.
Bruce Miller the 07 has a cross plane twin
Anonymous Anonymous the R1 makes 200hp out of a 1000cc engine with the ceros plane crank
finally! since one of the new teams in the V8 supercar series (Australia) have been using a flat design, I've been curious as to what/ how this works. Very informative, Thankyou.
I'm so glad EE bought a new microphone.
Very helpful and easy to understand information, thanks !
Informative, but should redo video with correct labels on title of blackboard. Order should be "Crossplane V. Flatplane V8 Engine" as this matches the details below the title.
Im so glad that your here. I have learned so much form watching your videos
As usual, an excellent, clear explanation of a concept I’ve wondered for some time. As for the drawings, they make the concepts clear, but keep your day job!😁
Perfect timing for the new Z06
Great explanation. I was reading about the new Ford Mustang GT350R having a flat-plan crankshaft. Had no idea what it was.
Hey buddy! Are you alive?
@@user-rx9ny4yo2e Yeah. Who's this?
Excellent guides to engine balance as well as this flat vs cross.
Anyone here after watching Shmee 150 talking about his GT Black Series having a flat plane Crank . Good video.
Still current after all these years. I always wondered what Ferrari was thinking when they built the 512 "Boxer", with its flat-plane crank. This, along with the design philosophy of small displacement-twelve small pistons-minimized rotating mass puts the maker into perspective.
Thank you.
Very good explain.i see this video's from Argentina and gone very easy understand.
I have a 21 MACH1 with Cross-plane Coyote 302 - and the 19 GT350 with Flat-plane - VooDoo 317 Ci. - BOTH amazing cars. I just topped my time in the MACH1 against the VooDoo. Even with the beastly VooDoo, the MACH 1 is simply a more apt pupil. Never thought I'd say that. Still, the times are so close it's amazing. - Excellent video, ty for explaining.
Corvette C8 Z06 gonna Blow this video up in 2021
Thank you ! Well done ! And yes...learning more about the C8 Corvette! GO CORVETTE RACING !!!
I turn to this channel when my college tutors are talking giberish, don't ever stop making these videos, I don't want to fail haha.
keep up the good work
Best channel on UA-cam
Beautiful explanation..... kudos to u mate
Excellent video. Very knowledgeable.
Thorough and clear explanation.
Excellent video series, I thoroughly enjoy the rapid-fire rate of information.
Nice, started reading a book about ICE last year, I didn't know what the author meant by flat plane and cross plane (Simplified drawings), thanks to your video, I could visualize. Cheers
Thank you for explaining all that my friend very nice video
Love the flat plane crank in my GT350!
Hi, I watch your videos regularly and really enjoy them. Could you suggest some books to become more knowledgeable in this stuff. At least I find it very interesting. Thanks.
Hey congrats - Jalopnik used this video in their article explaining the difference.
+parabola164 I like those guys!
Looks like you're about to get a TON of views :)
I really like your videos. Thank you for schooling me
Great explanation! Keep making these great videos.
For people curious, yes - most road cars have crossplane crankshafts. The typical burbly, low-frequency roaring V8 noise is produced by the firing order of crossplane crankshafts. This type of crankshaft was designed by cadillac and hence why it is refferred to as the "american" V8.
All ferrari V8's have used flatplane crankshafts in the past 50 or so years. Lotus esprit v8 and McLaren V8's are the only other road cars I can think of that have used flatplane cranks.
Great explanation!
The crank rotates, you don't need any bigger crank case, that's related to crank throw or stroke.
What a great source of info!
congratulations for making it on Jalopnik!
Jalopnik and AutoBlog on the same day - maybe I should make Nov. 17th a personal holiday.
Thanks, can't wait for the C8.
Well done, young man!
Thank you for the awesome videos man. I appreciate it!!
Love your videos and how you explain things! I have a suggestion. When using the white board, have you considered using a laser pointer? You may need to practice with it some, but I think it would be a useful tool in your videos.
Great explanation
Awesome video, homie!
Great explanation!!! 🏆 only took u 5 minutes to break that down, your the best man...
Man I really enjoy your channel! Awesome! Keep the good work!
Thanks!
Cheers mate good explanation
You can explain stuff really well, can you make a series about the technologies used in 2014 Formula 1?
Yep! Like others, Corvette news led me here. Now I know what it means. Great job of explaining. Thanks much.
Good job young man! Thank you.
Hey it's me from the future. GM Chevrolet just released a mid engine Corvette C8 Z06 with a normally aspirated V8, 8600 redline, wait for it, a flatplane crank!
I learned something new today! Thanks!
Thanks for the explanation.
Those glorious sideburns tho!
the first diagram of a crankshaft is a bit skewed.. is that on purpose? The one on the right looks more traditional.. ?
Am I the only one who ended up here looking for explanation about the new Z06 engine 😂
Nope 😂
Excellent video! In a world of the Kartrashians and crap, so happy to see that intellectual video's are still being produced. Thumbs up!
I'm here because of the crossplane crank on the r1. More advantages vs a flatplane on a bike. Looks like opposite for car world
Very informative, thanks!!!!
Kudo’s to you Mate on a easy to follow Video. I love my cars but are not mechanically minded, so now Im a bit more hooked up on how my new GT350 is gonna burn up the country roads around New Zealand! Yeah baby
really liked this one
easy to understand!great job!!
great explanation!
A video on exhaust scavenging or just how headers work and why they are shaped the way they are would be great! I agree with a few other people though, the illustration in this video is hard to understand.
I have videos on both! Search my channel for "exhaust." :)
Thumbs down guy must be on vacation. Great Vid!
great explanation thank you!
