Why some engines sound the way they do | Know It All with Jason Cammisa | Ep.02
HTML-код
- Опубликовано: 27 янв 2021
- Sound is an important part of the internal-combustion-engine experience, and many engine configurations have their own distinctive sound.
There are many reasons why, but one of the most important factors in an engine's sound is how evenly the exhaust pulses reach the tailpipes. Evenly spaced exhaust pulses tend to result in higher-pitched, smoother sound. Unevenly spaced pulses in deeper, more complex, and angrier noise.
In this episode, nerdy automotive journalist Jason Cammisa gives an oversimplified overview of the science behind this, explaining how the regularity can be determined by the crankshaft or the exhaust - and giving examples of each.
He covers 4-cylinders (the Honda S2000's equal-length headers compared to the Subaru WRX STI's burble), V6 engines (the Nissan VQ versus Ford EcoBoost), V8 (the Ferrari flat-plane crank V-8 versus an American cross-plane V8), V10 engines (the Lamborghini Gallardo even-fire V10 versus the LP560's odd-fire, which sounds like two 5-cylinders), and the Mercedes-Benz V12 with equal-length headers versus the factory exhaust.

The reason i watch more of Hagerty than normal : Jason Cammisa
Facts
1st class.
Indeed.
Dude! Magnus, Zach and camissa? Hagerty poached everyone 😂
@@johnsweeney5108 Farrah's showing up later too, I think
I was kinda hoping you'd demonstrate all engine sounds with your famously accurate impressions.
I second this!
I have to say I too was impressed with his impressions.
All you have to do is put equal length headers on your Subaru and it will sound like a Civic. Best subtle dig I've heard in a while, well done.
Mine doesn't quite sound like a Civic, but that might have something to do with the big cams that are in it also 😁
@@jsquared1013 I wonder if I add 2 so long headers to my inline 4, will it sound like subaru? :D
@@abdulkadirthecarguy1948 actually yes but you will decrease the performance
@@Naah732 but that is a whole other episode.
More like a jab with a hook 🪝.
Subaru engines should never sound like a Civic. VTEC is better!
Ah yes, the 4-door Zonda.
Do you know how much it costs by any chance?
@@Bijiketapang001 $12,000.00
@@ralionaarondp dayum
Lmao
@@Bijiketapang001 and u have to send ur car to japan as the guy who does it doesnt want to send it without him fitting it on and he doesnt travel, he only does it on the cars himself in japan
The straight piped Mercedes V12 was hilarious!
That Carmudgeon episode where you discuss the best examples of each engine configuration just HAS to happen.
Seconded 👏🏻
Hagerty is doubling down on keeping me entertained while I wait for their tow truck. truly innovative insurance.
More Jason Cammisa please!
I was kinda hoping you to show the differences between a Lamborghini V12 and an Aston Martin V12. One's a high pitch, one's a grumbling growl. And thanks for joining Hagerty. I'm a fan of you and Jack Baruth.
same principle as on v8's etc thats the reason he didnt
Lengths and pulses
the same thing with the mercedes v12 shown towards the end, different header design. astons have unequal headers, ferraris have equal length fancy manifolds
Look up: v12 vantage velocity ap headers. The difference in tone between lamborghini’s v12 and aston martin’s v12’s is simply down to the manifold design. The velocity ap design is much closer to lamborghini’s design. Also: the reason an aventador with a brilliant (aka stardropper) exhaust sounds just like a murcielago… the murcielago has equal length merge pipes and the brilliant exhaust for the aventador takes the unequal factory merge pipes and replaces them with equal length ones like the murcielago has.
Learned more in 5 minutes then watching 5 years of TOP GEAR . Jason with Hagerty is the modern TOP GEAR.
How did I know that Effspot would be the sound for the Mercedes v12 😂
I'm thinking of getting this done to mine, anybody happen to know what it would cost?
@@jetplume 12 grand + sending ur car to japan, the dude who does them doesnt build them and send them out, Savage garage already tried to get it but he refuses to send it and let someone else get its design
4:00 that was a really really good Subaru impression.
The best auto journalist bar none.
Holly hell.... I've watched and read every piece of gear head content I can get my hands on on the last 10+ years and I still learned a TON from this. Jason Cammisa is an absolute legand!
You have to love Jason - his "lectures" are a master class in making complex subjects interesting. Cracking series 👍
The use of the term "staccato" in an automotive video. Perfect imagery.
This makes me miss more the gt350 review from Jason camissa by dumbtrend
Man did they drop the ball by kicking this dude to the curb. MT content is weak outside of Randy Probst.
@@Peanutdenver they kicked JC out, made less RUclips content, threw out JC related videos, made their reviews more exclusive (paid). And their viewer count dropped.. Well good on them for making people pay to watch shitty reviews.
@@randomesteven3935 For sure, what a dumb move....and greedy.
@@randomesteven3935 They didn't kick him out... He's said numerous times he left on his own, he wanted some time to himself.
One of the mot useful and interesting videos I've ever seen...on ANY subject. Please keep up the great work, Jason!
As a twostroke guy we deal allways with pulses, header length, diffusers, resonance cones, etc.
Good video, nice examples!
I don't think I've learned as much since watching Sesame Street.
Can we get some appreciation for the cars in the back ground.
Genius as Mr. Cammisa is, I'm glad he had to focus on those rhythms as much as I did...
"Two five cylinders arguing with each other..." so in other words, polyrhythm.
Meshuggah enters the chat
Continues to do a "para-para-diddle" for the v8
Did you see him tap out that V8 rhythm? If he didn’t have a regular job I would say he is probably a drummer.
That was a BRILLIANT explanation! I particularly liked the examples shown with the hand taps on the table. That made it really simple to understand. With THAT said, a cross-plane crank Chevy V-8 sounds SOOOOO much better than a flat-plane crank V-8, IMO. That's one of the main reasons I'm not totally in love with the new Corvette Z06 and would rather have the E-Ray. The E-Ray looks like a Z06 but has the wonderful exhaust note of the Stingray.
Same thing with the Mercedes AMG GT Black Series. It's a beast of a car, but that flat-plane crank engine in it produces an exhaust note that sounds like ass, IMO. I would love to get one, yank that engine out and drop in a built naturally aspirated AMG 6.2.
Jason Cammisa is my favorite automotive RUclipsr! He does a fantastic job of being informative, scientific, and in tune with other enthusiasts. He is someone I feel like I could go have beers with my buddies and have an awesome time hanging out. Exactly who I want to teach me about cars and the internal combustion engine.
This is nothing short of enlightening! Thank you, Jason!
This was the best Know It All episode yet! So interesting, keep these coming!
Car school by Professor Cammisa is always the best!!
Ive read about this topic and kinda sorta got it but when you break it down using sights and sounds it becomes crystal clear. Thanks Jason!
Glad you touched upon how some exhaust configurations result in greater power -because that matters more than sounds for the sake of sounds.
It does to you and me but apparently not to most gearheads
Hmmm, that sped up human imitation of a cross plan v8 sounds familiar, i wonder were i've heard it before, maybe done with drums?
Perhaps comparing a coyote v8 with the voodoo engine? Seems like it was on youtube at one point
well the intro to hot for teacher sounds like a cammed v8 so i can see how that could be done
Paraddidle or something, I haven't played in years could be wrong
I've got it bad, soooooo baad, I'm hot for teacher!
This is such a great video! I feel like this topic doesn't get talked about enough. Thanks Jason and crew.
Really enjoying these episodes with Jason.
Excelent info with your clear an complete info, thank Jason
Im at 5 mins and I keep taking it back to the beginning ... because I dont want it to END!!! I could literally watch Jason kill it all effin day! I love him and his car brain.
Jason Cammisa has single handedly eloquently elaborated one of my curiosities about engines and cars. Big thanks bro
Always happy to see Cammisa content!
Phenomenal job explaining it and great visuals
Just subscribed!!! This was one of the best explanations of this I’ve heard from anyone.
So...
I subscribed thanx 2 Jason Cammisa. He’s far more knowledgeable than I’ve ever given credit for. I like his “prove me wrong” and/or “told you so” way of explaining stuff!
absolutely loving the content jason, keep up the good work!
Such a great video. I'm trying to learn more about cars and this uses the right level of detail and complexity. Also JC is really entertaining and clever.
Jason Cammisa, what an asset.
Man what a FANTASTIC video!!! Thank you!!!!
Kind of knew all this but the way it's explained is great and made it even more understandable. Bravo.
JC is the best automotive presenter period.... bren watching this channel for 3 days straight
I love this format from Jason.
Exactly what i was looking for, thanks for the explaination Jason, always a pleasure!
I love this guy. Very charming. Right mix of info and humor. He can be funny, but not trying to be a comedian. Well done sir. As a drum student.....I liked his tapping to explain engine pulse sounds.
Absolutely love this series
Keep them coming
Perfectly presented Jason!
Just from the name, I knew this would end with Jason playing the drums again. Glad to see some more video content with Jason Cammisa!
Getting through that video with no mention of the Quattroporte was impressive.
The grail noise!!!
Absolutely fantastic video
very informative. answered many questions regarding exhaust sound. awesome episode.
One of the only videos where I hit "like" before it even starts. Keep up the good work!
Man, this is my new favorite car channel now.
You should have your own television show!!!!!
Best video you have ever done Jason. Great job.
jason, great work as always.
thank you for picking up Jason! my goodness hes does justice to car journalism
This is great, and I’m super excited for all the new content!
You are top of the class. Unprecedented work. thank you for your videos.
Great stuff Jason, love your videos. And the impressions of exhaust are 👌🏽
please do more of these, I absolutly love it
I just realized that I am watching your vids with 2 diff ids.. and still love it
I'm amazed you could beat out the rhythm of the cross-plane crank on a V8 the way you did ... Nicely done! :o)
It's good to have you back in business Jason!
Jason is the man he’s the only reason why I watch your show
You know, I did already know this information...but I still watched because of Jason Cammisa. Glad I can again watch his personality as the host.
Very useful, plainly explained content.
Well done
Great info, down to earth examples!! 🙏🏼
Love these videos! Have always been a big Cammisa fan!
Subscribing just for this segment! So funny, so easy to understand! Bravo Jason!
Another great Jason video.
You’re brilliant the way you explain tech! Great channel!
Great video Jason, keep them coming!
The reason I watch Hagerty, period, is Jason Cammisa 🤭
What, no love for Tiffany on Daily Driver !?
@@ftby59mikeD Only when Cammisa joins (like the GMA T.50 one :) )
Same here
Awesome video, Jason! I have learned more about the real reasons I like certain cars from this guy!
Love this explanation. Well said and done sir👍👍👍
I’m glad that Jason is exhausting his knowledge for us all. Keep it up, Cammisa!
Jason is the real MVP!
Jason Cammisa, glad to see you on this channel!
Sensational. Jason really does know it all.
Love this series, Keep it up.
Amazing automotive lesson 👍👏👊
As usual, perfect explanation 🤗
Love it! These videos are like the “cliff notes” for car lovers! What to know and easy way to understand a particular thing car related? Watch these videos! Love it..and thanks!
Seeing Jason made double check if I’m subscribed
Excellent video, as always from Cammisa.
An interesting example of how exhaust pulses change the sound we hear is the 4.4L V8 from BMW. The current N63 and S63 use a “hot vee” layout, placing exhaust manifolds near each other. That enables BMW’s S63 (used in the M5 and M8) to cross two exhaust pipes from the opposite bank and mix the pulses evenly (for less turbo lag). As a result, the M5 and M8 (S63) sounds very different than the M550i and M850i (N63) even though the engine architecture is the same except for exhaust routing.
Great video. Well explained!
I have to say, I didn't know about Mercedes V12 mod, souds amazing.
Bunch of videos on here about it.
Interesting information. Thanx
That was swell. Thanks for the inspiration and keep on trucking!
Love this explained, awesome! I’m going to attempt to make equal length headers on my 280z later this year!
Mr Calcium any suggestions? I find it hard to find some of those resources because the titles are in Japanese!
Mr Calcium will do! Thank you!
Great lesson..!! I've had a couple of Subarus and driven many more. They have fun engines and that sound has character aplenty.
There's also the weird (but wonderful) TVR AJP V8 engine. It's a narrow block V8 (75 degrees) with a flat-plane crankshaft, which makes its firing sequence like a heartbeat between banks of cylinders badum, badum, badum... It's a REALLY angry sound.
My 4.5 litre Cerbera was dyno'd at 410bhp and had exhaust ends similar to those you'd see on a Stratos - conical shaped so they actually "trumpeted" their song at everything within a fairly wide radius. It was antisocial on one hand - it was considerably louder than even my 250bhp Caterham - but on the other hand it sang proudly of its capabilities.
Like this small bits explaining their functions.
I love these music videos. Thanks Jason
I already am a Hagerty Day Drive Club member. This video is another reason I’m happy to do it.
The year is 2050. This video is but an archival memory of a long forgotten era of something called the 'engine' and its melodious sonnets. It was a happier time.
