Before my father was born, my grandpa had a Buick straight 8. He put mothballs in the fuel, but wasn't the fastest driver. When my father's at home birth developed complications, grandpa put grandma in the Buick and hit the highway. Their friends were following in another car. All they could see in front of them was 2 feet of fire shooting out the exhaust of the Buick, untill they were out of sight.

Funny. Now that you mention it, when I was 5 yeqrs old in 1968, I watched my mother drive off to the hospital to give birth to my youngest brother, in our 1937 Oldsmobile with a straight 8 engine. He was her 6th child, so it wasn't a big deal, for her to drive herself to the hospital, as it was difficult for my father to leave his store. Even in 1968, a 1937 Oldsmobile was a rare sight in Atlanta, Georgia. It wasn't quite old enough to be considered a collector's item, and one car was as good as another to my mother, as long as it ran, so I'll bet the people at the hospital wondered, who is this humble, 9 months pregnant lady in such an old car, and will she be able to pay her hospital bill? Our 1937 Oldsmobile straight 8 was a two door and had two fold down jump seats in the back. My twin brother and I liked to use those seats, when we were 4 or 5 years old.

Simple answer: It would be slow and inefficient. If you want a straight-8 to survive even moderate RPM, you need 9 main bearings and that piles on frictional losses. Even then, the crankshaft would still not be as rigid as the short, stout, crank of a V8 so it would remain rpm limited.

Maybe you could produce a race crankshaft for an old engine? The typical way for more stiffness is a hollow crank and large diameter. With a low number of main bearings, there is no problem of friction. You only need incredible large connection rod Os. The in the crankshaft you need hollow sections with air to reduce the weight and keep the tubes for the oil to the conrod Os. To make the engine not even more long, I propose a second shaft next to the crank which connects to it through multiple gears ( thin ring on each counter weight ). This gives stiff end to end connection, damping ( oil in the gears, or even slippage for the gears + springs ) and you could run it at half the RPM and it becomes the camshaft, though I prefer DOHC and a (up to one tooth) 1:1 chain drive in the center.

It was so strong that Jeep bumped it up to 4.0L and used that engine for something like another 40 years. Dad had a 52 Packard with a I-8 with a 3 speed and an Overdrive. Back then Nevada had no speed limits. He would put extra pressure in the tires and drive 110MPH from LA to Southern UT (438 miles), where he was from, to go deer hunting.

My grandfather had a Buick 8 inline in the fifties, when petrol prices went up the took out four pistons with the con-rods and put bronze plugs in the crankshaft for number 1, 2, 7 and 8. The push-rods went out as well but the spark plugs and lead stayed. Running the engine on four cylinders as a taxi. Later the did something like that on a V8 Buick, they cut windows in the four outside pistons and left them in the engine, using it as a V4. On this one the spark plugs where removed and the leads where grounded. This was in Belgium second hand US cars where really cheap at the end of the fifties and early sixties. This was because all the US military went back home. A lot of these cars where used as taxi, converted to tow trucks, light commercial trucks and so.

I've only seen one running and it was running so smooth and so quiet you didn't even know it was on!

Quite simply, packaging. What a beautiful sounding engine though.

Many more I8 diesel engines were made, although most not for automotive use. A very well known one is the Gardner 8L3, many used in smaller vessels like canal barges and fishing boats, and also in small shunting locomotives. Then we have larger inline 8 diesels for railroad application like those produced by Sulzer, Fairbanks Morse, Hamilton and Baldwin to name a few.

In the 1920's Harry Miller was building 183, 122, and 91c.i.(1.5l) straight 8 dohc hemi engines in Los Angeles to race at Indianapolis and the high banked board tracks of that era. His famous "91" was supercharged and with methanol could put out 300 h.p. I believe it was this engine, or the 122 that Ettore Bugatti bought and copied to put in his Type 35 Grand prix car which was pretty successful. Look up Harry Miller and take a look at his engines. they are absolutely beautiful. Some Indy 500 races had over half the field with his cars and engines and won quite a few. He and his engineer, Leo Goosen, I think actually designed the front wheel drive unit for Cord as they already had experience on Miller's own "91" front drive Indy cars.

They also had an 8 inline engine for road use in natural aspiration (240 bhp) and later with a turbo at 300bhp. Fitted to many UK manufacturers lorries. It was a very smooth engine with a very different exhaust note and remarkably economic compared to the competition. Gardner engines were famous for their exceptional build quality and engineering. Many marine engines are still in use.

Well done vid. Perhaps I missed it, but weight was a large consideration for the evolution from the inline 8's, as well. (Increasingly so as engineering was better understood) For the example, the Buick Fire Ball Eight, was well over 1/2 ton complete (minus trans and bell). 1200 to 1400 lbs I've been told by machinist. By contrast, the OHV Buick V-8 that came out in '53 was a "light weight" casting, at under 700 lbs--about the 1/2 of the Eight.

I believe VisioRacer is based in Slovakia, not the UK. And how do you describe a V10 (or V20 when two are geared together) as an inline 10 ?

The Buick and Duesenberg straight 8 was such awesome engines

Yes. I have wondered why. Thanks Visio!

One cool feature of this engine configuration is that you can abbreviate it so beautifully. *Str8*

VisioRacer is quite right - inline engines have more of a problem with crankshaft torsional vibration. It wasn't a problem with the old American inline 8 car engines due to low compression design, and low power output. In the 1930's America, a long engine bay on a car was a status symbol. Post-war, long engine bays were considered ugly, and women drivers found long cars hard to park. So engines had to be shorter - hence V8's, not I8's, post war. An additional minor advantage of V-engines is lower friction. For any given cylinder swept volume, you would expect the power lost in friction would be directly proportional to the number of cylinders. However, for any given cylinder size and number of cylinders, the V-formation has less friction than the inline form due to the staggering of peak loads on each crank throw. For a while. I worked as the engineer for a dealer selling large industrial diesel engines. Over a whole range of an engine series, the cylinder size is always the same. One series we sold gave about 50 kW per cylinder, so if you needed 200 kW, you got an inline 4, if you wanted 300 kW, you got an inline 6, if you needed 400 kW, you got a V8, and if you needed 600 kW, you got a V12. And if you needed 800 kW, you got a V16. The V8 got the same size starter motor as the I4. The V12 got the same size starter motor as the I6. Of course the V16 had two starter motors fitted, each the same size as the one fitted to the V8 and I4. This is not the full picture though - for example the I4 cranked a bit faster that the V8. But the friction loads were close enough to allow starter motor standardization. The V engines needed only slightly larger starting batteries too. So, all up, a V8 is cheaper than an I8 for example.

I’ve had a dream for a few years, and I’ve been saving up to make it a reality. Hopefully in a few years I’ll have a new and improved straight eight to offer up. Hope!

I love how straight eights sound very close to 90 degree crank V8s. It's all in the way the cylinders fire bank-to-bank. But if you look at the firing order and/or the crankshaft of a straight 8, the first four cylinders mirror the last 4 in a 90 degree crank configuration. So in reality, instead of firing (L=left, R=right) RLRRLRLL, they fire (F=front, B=back) FBFFBFBB, the front four cylinders acting like one bank of a V8 and the rear 4 acting like the opposing bank. And with the exhaust pulses literally the same per each group of 4 cylinders per manifold, the exact same exhaust pulses as a V8 are going to come out. This was the only thing that surprised me about straight 8s. Now, if its crank looked like 2 180 degree cranks offset 90 degrees, it would "buzz" since the firing order between front and rear banks would be equal: FBFBFBFB (like in a 180 degree crank car).

Very interesting video, but you forget that the German tractor manufacturer 'Schlüter' used a 9.5l straight 8 engine in their 2000t (tv/tvl) model. With 165-195hp, build from 1970-1982.

Crumple zone is why. The same reason inline 6's are going out of favor. There has to be sufficient area in front of the passenger compartment for proper crush and force dissipation to protect the occupants. Engine blocks do not crush, they instead get pushed back into the passenger compartment. Inline blocks mounted longitudinally take up a lot of room that can be used as a crush zone. Look at trucks and SUV's with longitudinally mounted engines, the engine itself is placed as far back into the engine compartment as possible to provide as much crush zone as possible in front of it.

I’m working on a straight eight at work right now. I’m at a classic car dealership. 1951 Pontiac chieftan

Ain't hot-rodding beautiful?

Short answer: it's a really space-inefficient engine design. The long, narrow shape of the engine forces a longitudinal mount and demands a lot of the length of the vehicle be dedicated to the engine compartment. For most vehicles a V8 is just going to fit better. You still see inline-6s from time to time because they're still small enough to fit inside a conventional engine compartment in either a longitudinal or transverse engine compartment - to do that with an inline-8, the engine would have to have a very low displacement and then you lose the torque advantage.

The reason why the straight 8 died was few reasons fueling 8 cylinders in a straight line was a challenge as the middle cylinders got all the fuel while the front 2 and the back 2 usually ran lean adding more carburetors would help but went through more fuel also head gasket was a problem as so many bolts were needed to keep a good seal and the cylinder block was prone to warping around the half way area and because 8 in a row the engine was super long...as soon as the V8 came out the straight 8 was obsolete

Believe some large or powerful high compression straight 8's had a gear near the middle of the crankshaft that provided the power takeoff,reducing the crankshaft whip since it acted like a pair of 4 cylinder crankshafts to some extent Crankshaft whip can be visualized by using a very long socket wrench extension,compared to a short extension you will notice the twist that occurs before you reach much torque being applied,the problem with the crankshaft is that it tends to start winding up and unwinding in a sort of "torsional vibration" which adds stress,there are ways of trying to dampen this out to some extent with iron hubs surrounded by rubber,the rubber then surrounded by another heavy iron outer ring,also there are fluid filled dampers can be overcome to some extent by making the crankshaft thick through the bearings,high quality forged steel,also rigid stout heavy engine block with deep skirt Packard at one time had two blocks,one with 9 main bearings and one with 5 main bearings,I believe that during certain years both were available in 327 cubic inch displacement size,I believe Packard's were considered to be the best balanced,blueprinted and counterweighted of these ancient but very nice running engines along with a 9 bearing straight 8 made by Studebaker for the Pierce-Arrow during the time that Studebaker was associated with owning Pierce. (Studebaker's own straight 8 might have only had 5) I suspect that the early Duesenberg 3 bearing engine was quite unreliable and short lived,a toy think later Duesenbergs that won races had much improved engines or else the stories are just stories even the Pontiac had 5 main bearings

5:06 It was also used in the Salamander firefighting vehicle

5:10 also used in 1950s era fire engines in the UK 🙂

Its been a while since I've heard one they are so smooth and sweet sounding.

No mention of the 800 bhp English Electric 8SRKT engine used in the Australian D16 class locos which were still in use until very recently

Great Vid, lots of good content, the Cord would be a good exploration on too, they were quite ahead of their time. Updoots on your monetization situation, you are what makes KZread great.

There where a lot more you could have done with this. Where I live we had a locomotive called G class (english electric company) Only 2 made. I believe it is also one of the only straight 8 english electrics lefty in the world. They had a fantastic sound to them too.

Man it would be cool if a modern manufacturer would revive the straight-8 by giving it wider main bearing journals, more main shaft journals, a stronger crankshaft, stronger connecting rods and pistons, overhead cam design with timing chains, dual intake manifolds with single throttle bodies on both, dual 4 into 1 headers with a turbo attached to both and then fuel injection for efficiency, man I know I’ll never see one like that but damn it would be cool. Basically just 2 inline 4’s attached to each other longitudinally connected at the end of the crankshafts, both with single turbos.

I knew about all the automotive Straight 8s, but didn't know about Straight 8 diesels.

3:52 REO was pronounced as a word, like rio, despite the fact that the letters were the initials of Ransom Eli Olds. The band REO Speedwagon says the letters. Excellent video BTW

I pronounce the MAN brand as ‘maan’ and only received criticism that it should be spelled, although it is normal in my language to pronounce such names as a single word. Thanks

REO made trucks and lawnmowers! I think the trucks were made up into the 1950's An old advertisement for the lawnmower shows a parked REO truck with the driver in his uniform happily running a REO lawnmower (they were self-propelled and rather expensive with chain drive and self-rewinding starter) engine was cast iron and the power takeoff was from the camshaft!

@@VisioRacer It's hard, Americans say the letters of LED (Light Emitting Diode) but other English speaking countries say it as a word. It was invented in America so they are wrong,😉We try to mix it up to confuse everyone. While wikipedia isn't authoritative, they agree with your pronunciation of MAN. en.wikipedia.org/wiki/MAN_Truck_%26_Bus

6:00 Holy cow, was that Smokey Yunick hiding behind that engine?

Perskins make a straight 8 engine of 32 litres either gas or diesel fueled called the 4000 series (4008) for generator or pump applications.

Had a 1950 Packard with a straight 8, sadly it never ran and I just couldn't find the time to rebuild it, it had sat for 35 years without being turned over so it was well locked up

Rolls Royce B80 and B81 found itself in many Dennis and ERF fire engines. Side exhaust valve overhead intake.

Feel like this was a nudge from my uncle bud..always tried to teach me stuff. He had a beautiful 49 Pontiac Chieftain with a straight 8. Miss that guy.

Near every Dennis Fire engine 1947 to about 1972 were powered by Roll Royce B Series engines. London Machines did not have them. London Fire Brigade preferred diesel engines. Was a beast.
