The Best Sounding Straight-8 Engines In The World

[@mg2699]

I would love to see a modern I8 engine

[@yadidimeanmaine]

That would be interesting. I'd like to see Ford try a turbo straight eight as an intermediate option for their F-series pickups between the EcoBoost V6 and the PowerStroke diesel. They got enough money to experiment.

[@stephen9869]

I would love to build a 5 valve per cylnder turbocharged flat 8 engine with the warble of a Subaru/Porsche mixed with the unmistakable 8 cylinder sound. Mmmmm

[@Tom-Lahaye]

Could build that as a VR8, that makes it a bit shorter, as modern cars don't have these impressive long noses anymore.

[@CaptainD00M]

take two inline 4 engines and there you go

[@mg2699]

well modern BMW's have very long hoods

[@dginia]

Grandpa's late '40's Packard had a straight 8. In the 1980's, when he gave it to a son-in-law, it made the trip from Texas to Minnesota at interstate highway speeds with no problems. Got about 20 mpg. Had enough torque that you could start from standing in 3rd (top) gear. Yes, it was quite smooth. Packard's engineering reputation was very good, I understand.

[@jessebrook1688]

Packard made their own automatic transmission, so I'd say that yes, their engineering was top-notch. There were 7 other independents at the time, some of whom had much larger budgets to work with than Packard. All of them used GM's or Chrysler's transmission.

Rolls Royce made a straight 8 that was used in Dennis Fire Trucks, I remember working on one around 1980 or so.

[@frro28]

The small town of Virginia, in the Free State, South Africa used to own a Dennis fire truck. I once rode in it, the ride was as smooth as any car and the gear changes as smooth as you can get.

[@deutschedog3259]

Back in the early 1990`s I knew a guy in Liverpool England that had a Firetruck with Rolls Royce straight 8 gasoline (petrol) engine. I seem to remember the valve gear was inlet over exhaust. When he first told me he had a Rolls Royce straight 8, I thought it was the Diesel straight 8 they once made.

[@Starfireaw11]

That's the same B80 that they featured in this video.

[@Slaktrax]

It was also used by the British Military and known as the B80 and B81 series. Used in the Stalwart HMLC 6x6, FV432 Mk 1, Saracen APC and Saladin armoured car and some other applications. en.wikipedia.org/wiki/Rolls-Royce_B_range_engines

[@CaptainD00M]

Straight-8, because v8 is too compact

[@EddSjo]

CaptainD00M the straight one has better natural balance.

[@CaptainD00M]

that is why i think that inline 6 > v6

[@Y10Q]

V6 is very unbalanced, almost as bad as I4. V8 is a little better than V6. However, Inline 6 and I8 are perfectly balanced. Flat 4 is almost as good as I6 but flat 6 is just as balanced as I6 or I8

[@waswestkan]

I belie the 60 degree V6 is considered to be a naturally balanced engine & should be compared with the 90 degree V6.

[@Y10Q]

all you have to do is look at the counterweights on the crankshaft. Subaru flat 4 crankshaft weighs 18lbs stock. Honda or Toyota Inline 4 is twice as heavy at around 35-40lbs. All the V6 crankshafts I saw were 60lbs or more.

[@KentuckyRanger]

Straight 8s were awesome engines! I think what made them popular in older cars was the huge amounts of low-end torque. It took torque to get those huge, heavy, cars moving, LOL! And the balance was awesome! That's why straight 6 engines thrived for years! Smooth operation, lots of torque, and they last forever!

[@sebastianb5997]

@@ssimon64 Lmao but that's where it originates from tho, Straight 8s/inline 8s have some of the most unique rasps in existence. Sure we have new V8s and Flat 8s but they never quite have the correct sound. The coyote engine in a 5.0 mustang, for example, doesn't really sound all that aggressive even with a straight pipe, only with a cam does it wake up the motor. Straight/inline 8s sound like what all 8 cylinders should lol

[@movinmetal2596]

I watch a video of the Mercedes W25 at least once a week. That engine sounds so beautifully violent, I would love to build a custom chassis just for an old Mercedes or Packard straight-8. Twin gear driven superchargers would be a must-have :)

[@aaronschulz9896]

I love it too, and I also like how you have to Push the throttle between the gears.

why 5 valve per cylinder? Flathead might be "good" for 4 valves. Having a 5 valves per cylinder would have screwed your compression ratio and also the combustion chamber shape would have been terrible.

they sound like an American v8 a lot. is it because inline-8 engines naturally have cross-plane crankshaft configuration?

[@trevoncowen9198]

Bang Gegep the mazerati I8 has a flat plane

[@edlingja1]

Bang Gegep The engines can be any way the designer wants. There is no rule that says each particular configuration uses a set design. There are "flat" 12's that are really just modified V8 + V4 engines canted nearly all the way down.

***** I think it's (arbitrary) fuel economy standards more then anything that the US government is trying to push. But, even so, we're still cranking out 700HP supercharged hemi's that are emissions compliant.

[@nthgth]

Everyone always says "American" V-8... remember that the cross-plane layout (and thus sound) is characteristic of EVERY production V-8 EVER with the notable exceptions only of Ferrari, Lotus, McLaren, and one very recent Ford. So you're also talking about German, Japanese, and South Korean V-8s too :) Edit: Almost all English V-8s too! (save for the Lotus and McLaren I mentioned) ...sorry to threadjack. +Bang Gegep Good question, and I agree. Though I don't really see how an inline engine could have cross vs flat plane on its crankshaft. Maybe it's mainly exhaust pulse timing like 177SCmaro suggests?

Nice rigs, decent quality audio/video, well attributed and, best of all, exactly as advertised. Subbed. BTW drove a similar Buick 8 back around 2000.

[@zefanyabrian7831]

Man that W125 sounded like apocalypse itself.. imagine wrestling 560 horsepower with those tires and brakes!!!

[@jcgabriel1569]

In 1958, Tony Brooks, then a Formula 1 driver, demonstrated W125 with fellow Formula 1 driver Peter Collins. During his stint demonstrating the car, he noticed a vibration when accelerating, and pulled into the pits to report it to the mechanics. They just sent him out again, saying that the vibration is caused by _near constant wheelspin when on throttle._

[@donaldasayers]

The balance of an in line 8 can only be realised with a very rigid crankcase. WO Bentley was very suspicious of the RR straight 8, the crankcase looked far too flimsy to be rigid enough. He was right, it was vibrating all over the place, but RR hand mounted the engine at the nodes of the vibration so the vibrations never made it to the chassis.

[@BobCalNor]

Due to the length of the engine, torsional vibration in both crankshaft and camshaft can adversely affect reliability and performance at high speeds. In particular, a phenomenon referred to as "crankshaft whip," caused by the effects of centrifugal force on the crank throws at high engine rpm, can cause physical contact between the connecting rods and crankcase walls, leading to the engine's destruction. As a result, the design has been displaced almost completely by the shorter V8 engine configuration.

nice video but there is a mistake... i have in front of me a book called "Motor's Auto Repair Manual" published in 1953. my father bought it along with a used 1948 Chrysler station wagon - he traded in his 1933 Packard on it when he married my mother. you state "Not much is known about these engines". this book covers every American-built auto from 1935 to 1953 and contains ALL of the detailed specifications for every Packard engine used during those years. 385 cid was the largest variant but was discontinued in 1937, afterwards displacement fell to 320 ci. the 356 was introduced in 1940 and was used until 1949, when it was replaced by a 327 cid motor. also, horsepower for the Duesenburg 425 cid straight 8 is listed in an earlier edition of this book (i also have) as 265 - still outstanding for it's day - but that is for their production engines... race engines may very well be over 300 as you say.

It would need to be 1:1 compression ratio if it was 50 mm aways from TDC if my math is correct.

[@oscarzt1652]

50mm would lead to a 3:1 CR out of a 100mm stroke because at bdc total distance would be 150mm. the combustion chamber is 17.4mm away from TDC because 100/5.75=17.4

On the Buick, it was not listed as a carburetor, but in actuality it was a squirt bottle!

Straight eights are one of four engine designs with inherent primary and secondary balance. THe other three being: Straight 6, V-12 and V-16. Visio, thank you for making these compilation videos and crediting the original posters, as well. I don't mind your narration, though your accent is quite thick, and I can believe that some might find it hard to understand. Have you considered asking a native english speaker to narrate for you, as in the Kurzgesagt video series?

[@88manta88]

also the v8 but only crossplane, not flatplane

88manta88 V8 requires counter weighted crank to achieve primary balance, hence it is not considered inherently balanced.

[@Drunken_Hamster]

Also all boxer type flat motors.

[@aidanp.1451]

Or perhaps add subtitles.

[@MaestroTJS]

The first car looks like the car piece in Monopoly. :P

[@56pw]

I cant believe you dont have the CHRYSLER straight 8 on this list??? They probably made more of the straight 8s than every one on this list COMBINED...They were not only famous in cars they were VERY popular in many different manufactures of luxury boats and launches. Not sure whats up with this list.......

[@ElevatingEurope]

Read the title again, I’m pretty sure it says “best sounding”.

[@wayfastwitey13]

I've ALWAYS wanted a straight 8. oh my GOD!¡! do they sound absolutely amazing..

[@retroman3075]

Now this is how a car should sound.. not the annoying fart sound of modern four cylinder crap.

[@retroman3075]

Engines are engines. It doesn't matter if I am comparing different "classes" of engines based on sound... Some like the sound of a two stroke, some like the sound of a 4 stroke.. two different classes, but fair comparison.

[@retroman3075]

Dude settle down, its just an opinion... and it is fair for me say that some engines (mainly modern 4 bangers) sound like crap to me... What is there to argue? I dont like the sound of four poppers and I haven't heard a good sounding one ever.

[@branon6565]

Packard's were top of the line luxury cars back the day, my Grandfather loved his, it had a very smooth running straight 8 in it....

[@BlueXonar]

You could have picked a video of the Alfa where it was actually running properly... lol

[@DenGuleBalje]

Extremely difficult. An Alfa only runs properly once every 7th full moon.

[@thepotator8150]

You didn't mention the Scania straight 8 diesel. Built in sweden in the fifties, it's called the "Scania D812", it's naturally aspirated, has 11.5 litres of cylinder volume and it makes 155 hp it was mainly used in light passenger trains and shunter locomotives. There is also a turbocharged version called the "D815" and a marine version called the "D816".

[@duncan9168]

i like the voice over!

[@americanpanzer4163]

The old Alfa 8c sounded really nice

[@upsidedowndog1256]

Weight and length will keep these as historical novelties, but they were real cool. Nice video montage.

[@matthewmcdaid7962]

My parents had a 1950 Packard with the straight 8 engine. It was ten years old when mom traded it in. Prior to selling it she took it to the local garage and asked the mechanic if the engine sounded all right. He asked her to start it up, and she replied "It's running." "Ma'am, there's nothing wrong with that engine!"

[@cubus1510]
