Why some engines sound the way they do | Know It All with Jason Cammisa | Ep.02

Genius as Mr. Cammisa is, I'm glad he had to focus on those rhythms as much as I did...

Best car content on the internet. We need a show with Jason, Chris Harris, and ????? (Comment below)

Like this small bits explaining their functions.

Wish you were my shop teacher in High school

I like the sound of the vq35.

Cross plane v8s be playing a para-para-diddle-diddle

If we also put the firing order into the game we'll hear that dual cylinder bank engines (V's, VRs and boxers) will make iconic engine notes if the firing order involves two subsequent ignitions happening on the same cylinder bank.

The crossplain American V-8 is still the best sounding motor ever built, just like Harley is the best sounding bike

Flintstones paddling feet engine sound remains the finest there is.

WHERE is the VR6, Jason

No homage given for the wookie sounding VR6?! ARRRRRRRRRRRR

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.

HI, Jason . Love your vids. I have a question why do mustang 5.0 sound like they do?

So if you put unequal length headers on a civic will it sound like an STI??

Learned more in 5 minutes then watching 5 years of TOP GEAR . Jason with Hagerty is the modern TOP GEAR.

Looking forward to the episode about exhausts!

I hoped to see lotus sound from a Camry engine. Still curious.

You didn't play the cross plane v8, you played the Ferrari but not the gm small block.

There are plenty of other factors that affect exhaust note too: piston diameter, exhaust port volume, compression, engine speed, even the radius of the exhaust port. Valve lift, duration and timing even have an effect.

Ok, but what is with the fart can noise and backfiring?

That video of that subaru with equal length runners made me uncomfortable

You forget to mention X pipes, x pipes will make an american small block scream.

I sure wish someone could explain in simple terms the awful sound Renault PRV V6 90degree odd fire used in the Delorean, & how to tune the exhaust & engine to sound better. Only the French tuners seem to have a grasp on that engine used in their cars, Volvos, ect....

Why European sounds so magnificent…..

Gilbert Gottfried 50 shades of grey audio book please

cars are stupid. How dumb. Jason not be smart. Try going to school Jason.

This has taugtht me why the Jaguar V8 differs from a Ferrari or Lamborghini Scream ! Cross vs Flat Crank !!! Beautifully
explained

Always great stuff. Like the NA side of Car Sos

Jason, you left your headlights on...

Ford’s 3.5l V6 in the Raptors sound like absolute ass. I’ve never heard a truck sound so bad. Now I know.

This guy is awesome!

Should give a shout out to plenums too

I prefer the “guttural” sound of an uneven firing V10. Just sounds angry.

Getting through that video with no mention of the Quattroporte was impressive.
The grail noise!!!

So, for one, yamaha makes a cross plane crankshaft inline 4 which on its own has an uneven firing order. On that premise, a cross plane v8 is basically 2 cross plane i4 engines joined at the crank, so, in theory, since you have one exhaust pipe per bank, you don't hear an 8 cylinder engine but 2 4cyl engines side by side and since individually they are firing unevenly you hear that burble. Also, notice how sport bikes sound like a formula 1 v8 and how all V engines have an exhaust pipe for each bank. So, my question is, if all the V engines are basically 2 inline engines join at the crankshaft, if you joined their exhaust pipes into one down the length, shouldn't the resulting sound be much higher pitched than it is now? With current v8 engines you have one exhaust pulse coming out of the pipe every 180° of crankshaft rotation and you have 2 pipes. So, if you joined those into one, wouldn't you get 1 pulse every 90° instead and basically have a higher pitch sound coming out of the exhaust at the same RPM?

The V8 in the BMW M5 is a noteworthy mention that Jason missed. It sounds like a flatplane crank V8 even though it is a crossplane one. It retains the first-order and second-order balance advantages of a crossplane V8, while sounding much smoother, almost like a flatplane V8.
That is a result of a clever design having the ‘hot-V’ layout and with exhausts crossed over.

Sad I can't do equal length twin scroll on my wrx.

👍👍👍👍

Hey @JasonCammisa Still waiting on the video about exhaust scavanging!

After hundreds of years developing things that sound great, people choose explosions over trombones... 😞

You should have your own television show!!!!!

The crossplane is pretty much doing a para- diddle 😂

I like this guy better every video.

This sound composition art should be used for electrical trash. Most electric cars want to synthesize sound instead of use acoustic and air.

Does the engine head have anything to do with it? Because the Toyota V4 3rz engine has a different tune than the V4 2tr, even though the engine size and system are the same.

Excellent - thank you.
