It was printed in 1946.

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.
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!!
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 often have questions about various stuff like this and end up watching numerous videos without being any wiser. I don't know why I don't just come to this channel first and avoid the wasted time.
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!
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.
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).
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.
One of the best channels on TH-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.
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
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.
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.
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.
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.
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.
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.
Your videos on TH-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.
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.
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!😁
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
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.
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!
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.
Oh man so I know Twin Scroll Turbochargers are really only for 4 Cylinders Engines because of the way they fire and separate the exhaust gases. So does this mean if you go Twin Turbo on a Flat Crank that you can make those Turbos Twin Scroll was well? That would be Awesome!
Thanks! That was really informative. Does the mid engine corvette use this because it allows for the smaller crank case which in turn allows the engine to sit lower?
Crossplanes sound better imo. Just listen to the wonderful blubling noises that muscle cars make And a NASCAR crossplane V8 at 9500 RPM just has an absolutely unique screaming sound that no other car can match
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

Nice spent 20mins reading on a website to find the difference between the two, no luck, you nailed it in the first minute 👍🏻
I'd love to see a video on W12 engines, these are definitely my favorite explanation videos on TH-cam.
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.

Cross planes also have the famous v8 burble
And the flat plane v8 has a disappointing four banger sound.

davidrobert2007 idk what is disappointing with f1 sound?
The flat planes do sound, uh, rather pitiful.

Could you do a video on v10 engines as well?
Thoughts on coming back to this to explain why Ford chose flatplane on the new gt350?
He TOLD you.
is secondary imbalance just a comfort thing? or does it affect engines longevity?
More of confort. It does affect longevity a bit. It also limits engine redline, therefore limiting performance
They can seriously affect longevity depending on the amplitude of the vibrations. Which is why most flat plane V8's are relatively low displacement. This keeps the vibration fairly low.
Try to use CAD programs, it will be much easier ;)
One more advantage of Flat: they are cheaper
Can you please explain the directions of the secondary forces on that Crossplane? Btw, big fan here. I study Mechanical Engineering at Portland State and hopefully I can meet you in town some day!
Yes, this should have been explained more clearly
