The Ten Craziest Engines You Can’t Buy Today

Deartháir November 20, 2009 In General
Crazy? I'll show you crazy!

Crazy? I'll show you crazy!

Wednesday, over on Jalopnik, they ran an article about the Five Craziest Engines You Can Buy Today.  We liked it, and we liked it quite a lot, actually. Nevertheless, we can’t help but think there’s a slight flaw in their logic — besides the huge, glaring omission of the Volkswagen Group’s series of W-engines, of course. Many of these engines are very nice, it’s true; but they’re hardly what we of the Hooniverse would call “crazy”. Most of them are pretty tame, if you ask us. So while we think Jalopnik did a great job on their selection of engines you can buy today, the entire Hooniversal Brain Trust sat down last night and discussed this. Let’s have a look at what “crazy” really is.

10. The British Racing Motors H-16 Suggested by Tomsk

The BRM H16.

The BRM H16.

In concept, the H-16 makes perfect sense. It’s essentially a pair of flat-eight engines connected to a common drive gear. As such, it gives you all the benefits of a large, powerful 16-cylinder engine with the cost-savings of being able to use parts from a common V8 engine. Unfortunately, in the case of the BRM H16, classic British attention to detail appears to have been its downfall. The designers claim that their engine specifications were never followed correctly, and as a result the castings ended up far thicker than they needed to be. As a result, the engine was a huge, appallingly heavy thing that the legendary Jackie Stewart described as being “better used as a ship’s anchor than as a power plant”.

9. Rootes TS3 “Commer Knocker” Suggested by Han_Solex

The Rootes TS3.

The Rootes TS3.

See if you can follow me here. The Rootes TS3 is a high-speed, two-stroke, three-cylinder, six-piston diesel engine. Wait, what? Yeah, that’s right. I expect I’ve made my case right there, but let’s continue on. It uses two horizontally opposed pistons to generate compression and ignition in each cylinder. The cylinders are on rockers, like a standard pushrod engine uses for their valves, but much, much bigger. The rockers then connect to the crankshaft. You know what, just go here. They explain it better than I can. The 3.5L engine produced a respectable 135hp and 335 lb-ft of torque. Those are respectable numbers… but hardly groundbreaking, so the engine is stuck here at position nine.

8. Cizeta V16T Suggested by Graverobber

Hey look, the actual engine! Thanks Braff, and Ray, and mom, and the Academy, and all the little people...

Hey look, the actual engine! Thanks Braff, and Ray, and mom, and the Academy, and all the little people...

I spent forever looking for a photo of this engine. Some guys named Ray Wert and Jeff Glucker found photos in like a minute. That’s a little irritating, but it should indicate just how rare these cars are. In fact, they’re quite the amazing vehicles, with a ton of trivia — but we’re only interested in the engine for now. Now, the name V16T is meant to imply a V16 engine, Transversely mounted. In fairness, however, it is not. In fact, in the interests of accuracy, it is two 90° V8 engines, mounted back-to-back and driving a central gearbox. Read that again. A central gearbox, with a V8 on either side of it, all in a common block. So it’s not two separate V8s, it is one engine, comprised of two V8s. Jeebus, my head hurts just trying to understand it. I need pictures. However, for all its mind-blowing awesomeness, it produced performance that was still around the same as any other supercar. If the only other car with specs that rival yours is the Veyron, in fairness, you should be able to run with the Veyron. It can’t, so it’s stuck down here at number eight.

7. JRL Choppers’ Rotec R2800 Suggested by Graverobber

The Rotec R2800. Think of it as 3½ V-twins. Kind of.

The Rotec R2800. Think of it as 3½ V-twins. Kind of.

The engine, by itself, isn’t all that amazing. It’s admirable, to be sure; it’s a very small Rotary engine intended as a replacement for the (generally quite poor) gasoline engines that are usually found in small two- and four-seat aircraft. JRL Choppers decided to take one and put it in a motorcycle. For sheer inappropriateness balanced against mind-blowing awesome, it gets the number seven spot, even if, strictly speaking, it probably doesn’t belong here. Let’s face it, we’re hoons, we like anything that’s a little bit batshit insane.

6. GMC Twin-Six Suggested by Mad_Science

The 702cid GMC Twin-Six.

The 702cid GMC Twin-Six.

Due to its nickname, the “Twin-Six” is often mistaken as being two commercial GMC V6 engines somehow welded together. And in fairness, at a casual glance, it sure as hell looks like it. In the interests of interchangeability, it uses two V6 exhaust manifolds for each cylinder bank, and two V6 valve-covers, two distributors, and so on. Many of the parts for this massive 702-cid V12 were interchangeable along the entire line of GMC’s V6 engines, which kept not only production costs but costs of ownership remarkably low. For that huge level of consideration, and its resulting cool, we’re bumping this engine — which is largely just a big production truck engine — all the way up to  position six.

5. Anything Used by Blastolene Suggested by Braff, indirectly.

Blastolene says, "It'll fit."

Blastolene says, "It'll fit."

Braff suggested a few different engines, such as the Lincoln Flathead V12 or the pre-war Cadillac V16 engines; any one of these really does deserve to be on the list just for the sheer number of cylinders; the problem is, however, they just weren’t that awesome. Low horsepower ratings, poor reliability, and heavy weights served as limiting factors until they were heavily re-worked by the aftermarket. It’s only today, with our newer technologies, that some hot-rodders are managing to accomplish some really wild things with them. Does that make them awesome? Well… in the hands of a company like Blastolene, yes. Just go look at what they do. They’re building hot-rods around tank engines, aircraft engines, old Peterbilt engines… frankly, I wouldn’t be surprised to see a diesel engine from an old naval destroyer showing up in a future rod. Batshit insanity, and the usage of engines wholly inappropriate for road-going vehicles gets them an automatic spot at number five.

4. Bugatti U16 Suggested by Deartháir

The King-Bugatti U16.

The King-Bugatti U16.

Similar in concept to the H16 engine above, instead of using two flat-eights mounted horizontally, the Bugatti engine uses two straight-eights mounted side-by-side and vertically, all in a common block. When this engine came out, the straight-eight was seen as the epitome of power, style and all-around awesomeness. Bugatti capitalized on this hype by using two of them! Simple, effective, elegant, and over-the-top insane, just as all proper Bugattis always have been. Unfortunately for us, this engine, a 24L behemoth, never really found a proper application. It was attempted as a tank motor, an aircraft motor, and after WWI, as a concept-car motor. It was even attempted briefly as a “quadremoteur” version, which featured a 48L displacement and four banks of straight-eight engines. But it never went anywhere, and never really got used for anything other than a few conceptual tests, so while it would be fighting for the number one spot, it’s relegated down here to number four.

3. Ford 427 SOHC “Cammer” Suggested by Mad_Science

The "Cammer".

The "Cammer".

Wait, what? What’s so crazy about this? It’s just a big V8! Well, yes, but we’re granting a bit of leeway here; it’s not the engine itself, it’s the mentality that went into developing it. Essentially, Ford just wasn’t quite doing as well as they would have liked in some obscure racing series called “NasCar”. I know, I’ve never heard of it either, but apparently it was popular back in the 1960s. It seems people thought it was fun to drive in circles around a banked track; presumably you go as fast as you can until you get dizzy and vomit, and the last person to vomit wins. Sounds like fun! Regardless, it was terribly popular back then, and it gets a nod from us because of the Ford engineers’ mentality when designing it. They started with the best engine they had, the FE 427 side-oiler, and set to work improving it however they could. They looked at every high-performance engine available, whether it was from Chrysler or Ferrari, and adapted its best piece of technology to be added to the Cammer. Single overhead cams, exotic high-temperature valves, factory porting and polishing, hemispherical combustion chambers, tunnelport high-rise intakes, and a complex series of idler pullies to idealize the valve timing; all the tricks your average backyard mechanic would use to get more power out of an engine were already employed at the factory. In addition, Ford told the Cammer owners tricks they had learned of how to get more power. The engines were conservatively rated at around 650 horsepower from the factory; as each engine was hand-built, that was considered to be the “minimum” rating. Most had significantly more. Yeah, it’s just a big V8, but it’s kinda awesome.

2. The Rolls-Royce Merlin Suggested by Deartháir

The legendary Merlin. All. Hail. Merlin.

The legendary Merlin. All. Hail. Merlin.

Let’s face it, the Merlin is one of the greatest engines of the 20th Century, and anyone who says differently is clearly a terrorist and hates freedom and love and puppy dogs and all that is awesome. It’s been used for absolutely everything; marine, aircraft, tank, commercial truck and hot-rod applications. Didn’t know that? Sure. The Merlin engine was actually only the original, supercharged V12 engine, but it was used in many different forms under many different names. Simply removing the superchargers, or changing the crank, or swapping out the heads, or using different pistons, each resulted in a different name designation, but for all intents and purposes, it was still the original Merlin engine. Merlin was intended to be one in a rather large series of engines from Rolls-Royce, ranging in displacements from about 10L all the way up to almost 50L. As it turned out, the Merlin hit that sweet-spot between all of them, with the small footprint they needed for the smaller engines and the high horsepower they needed from the larger engines. It is versatile, powerful, and (for an aircraft engine) relatively lightweight. It’s little wonder that for over 60 years, when thinking of an over-the-top engine for an automotive project, the Merlin is one of the first ideas that comes to mind. Got a favourite Merlin-powered hot-rod? Post it in the comments, let us all drool about it. Let’s face it, if it weren’t for the engine that trumps it, this would rightfully be the number one engine. At 27L displacement and anywhere from 1300 to 3000 horsepower, it’s a hard engine to beat.

1. The Chrysler A57 Multibank Suggested by Murilee the Saucy Minx

Sweet Leaping Jeebus, it's the Multibank.

Sweet Leaping Jeebus, it's the Multibank.

Yes, the Merlin is a hard engine to beat, but if anyone is going to do it, it’s gotta be this one. Five banks. Thirty cylinders. 1,005-cid displacement. Constructed out of five of the Plymouth flathead sixes, it was designed to be adaptable and durable, and available in the shortest time possible. Simply put, America was going to war (finally), and they needed engines to power their Sherman tanks. Chrysler’s solution was simple to create, used existing parts, maximized flexibility, shifted paradigms, and utilized dynamic synergies. I have no idea what most of that means, but I’ve been talking to Braff again. Chrysler claimed that the Multibank would still be able to power the Sherman even if two full banks out of the five were disabled and not functioning. Good to know that even back then, Chrysler was planning their products around poor reliability. Oooooooh. Let’s face it, this is pretty frickin’ awesome. Go check Murilee’s article over on Jalopnik for some video deliciousness.

So, dear readers, what did we miss? What horrendous errors have we made? Fire away in the comments, maybe we can do a followup post. Or, someone else can, that was a lot of bloody work.

Currently there are "123 comments" on this Article:

  1. joshuman says:

    The image search results for "destroyer engine" are not what I was expecting. There is a lot more Star Wars than Arleigh Burke. I did eventually find the USS Slater, a Cannon-class destroyer escort that served in the mid to late 1940s in the United States Navy. There are a number of photos of its V16 diesel available here: http://www.williammaloney.com/Dad/WWII/DestroyerE… A compact unit it is not.

    Holy damn you have no idea how bad I want one of those 427 "Cammer" engine. Nothing screams awesome like a 7 foot timing chain.

  4. atr_hugo says:

    Dam – a Cizeta T-drive. Is there any chance I could punch the bore out a bit on that engine? ; -)

  5. I'd add:
    The Duesenberg Model H Aero Engine. http://chuck.goolsbee.org/images/cannonball09/2-H
    The Alfa-Romeo straight eight (with center-mounted timing chain!): http://chuck.forest.net/jag/z_car_photos/z_car_ph
    Any pre-war Bugatti engine!

  6. One thing about that Rolls-Royce: airplanes got 70 hp and 10 mph just by angling the exhaust ports backwards, because the exhaust gasses were exiting at 1,300 mph.

  7. engineerd says:

    Oooohhh…the Merlin. Only to be followed by the most insane engine of all time. My favorite Merlin-powered hot rod was the Supermarine Spitfire. Oh, you meant cars. Well, how about some useless knowledge about the Merlin? The first prototype Merlins were designed to use evaporative cooling. What's this you ask? Generally, in a water cooled system you don't want the heat transfer fluid to boil. However, there was a thought that if you let the fluid boil it could remove even more heat and become superheated. Unfortunately, this meant you needed condensers in place of the radiators on a traditional water-cooled arrangement, and the the condensers needed to be much larger than the radiators. On high speed aircraft, this adds a lot of drag so it was abandoned.

    For crazy engine you can't get today, I would say the ZAZ air-cooled V-4 engine used in the Zaporozhets. For nothing else than it is the antithesis of the Merlin.

    • Standpipe says:

      The Napier Sabre engine beats it hands down on complication, ingenuity, and power. It's an H 24, ie two flat 12 motors one on top of the other, sleeve valves, gear drive to the propellor, two stage super charging. A far mor advanced motor than the Merlin, with a reputation for unreliability, but LOTS more power

  17. aaronx says:

    More Merlin Trivia:

    It should probably re referenced as a Rolls-Royce/Packard Merlin. Rolls-Royce didn’t have the manufacturing capacity to build as many Merlins as the RAF wanted, so they asked Packard if they could build some. Packard re-designed the Merlin to allow for mass production (‘FTFY’ as it were), something that freaked out the Roller folks at first. When they finally got some of the Packard Merlins into the shop, they found them to be superior to the hand-built ones and apologized (and switched their own tooling to Packard’s design).

    You can still get parts for them pretty easily, thanks to air racing and ‘classic’ powerboat freaks.

  18. Joe Dunlap says:

    Just a couple of small corrections. The BRM H16 was 2 V8's laying on their sides, connected to a common central output shaft which also added significantly to the weight. Colin Chapman was quoted as saying, "We knew we were in trouble when the engine arrived at our door, it took 4 stout men to lift it from the lorry." The Rotec is a "radial piston" engine, not a rotary as in Wankel, NSU, Mazda or whatever

    • Deartháir says:

      You're totally right on the radial. I can't believe I typed Rotary. Clearly I'd been going for too long at that point.

      With the H16 however, you might wanna check again. I've got diagrams and multiple articles that confirm: two flat-eights, not two sideways V8s. Are you thinking of the W16?

      • Tanshanomi says:

        Actually, it's a common mistake. There were "rotary" piston aircraft engines that were very similar. As opposed to a radial, a rotary had the crankshaft bolted to the airframe and the propeller bolted to the crankcase. That way, the cylinders when spinning around with the prop, supposedly facilitating better cooling.

      • Joe Dunlap says:

        Im pretty sure it was 2 v8's. If you look at the picture, the plug wires route 4 to the top and 4 to the bottom of the visible bank, aligning pretty much with the intake trumpets. I have seen engineering drawings as well, but cant locate them at this time. There was also a BRM V16 F1 engine in the early 50s, Supercharged and front mounted in a BRM chassis as I recall. One large complaint about it was that because of the complex steering linkage needed to reach the front wheels, there was quite a bit of freeplay at the wheel. Not exactly confidence inspiring to say the least. Another fail for the Brits.

      • Crank says:

        BRM had made (at different times) both a H16 and a V16. The V16 was too heavy, apparently. The H16 which was in essence 2 flat eights, one on top of the other, failed because of torsional vibrations destroying the gears connecting the two crankshafts together. It also used a centrifual blower which ment it would go from no boost to too much boost in a narrow range. As one writer put it "At low speeds it couldn't get out of its own way!"

  19. Alan says:

    The Bugatti/King/Duesenberg H16 is very coolno doubt, but have you ever seen the Bugatti Steam engine? Variable valve timing and flat twelve construction from the late twenties. Looked architectural and blocky like a true Bugatti motor should.

  27. P161911 says:

    I had to do a little research on the BRM H-16. A few years before they built the H-16 they built a 1.5 liter V-16, yes a 1500cc V-16. I remember this from Nick Mason's book At the Limit. It was the only car out of all his cars reviewed for the book that they couldn't get to run long enough to do the tests.

    • Matt Dupuy says:

      It was a SUPERCHARGED 1.5 litre V16, no less. It allegedly generated 600hp at full chat, although it was rarely running for long enough for anyone to test.

      For other engines, how about the Lotus 59, which was powered by a Pratt & Whitney gas turbine and nearly won the Indy 500. And if that isn't road vehicle enough, how about this?:

  29. scroggzilla says:

    WHAT?!?! NO NOVI V8?!?!?!

      • scroggzilla says:

        Used extensively at the Indianapolis 500 for 3 decades, designed by Bud Winfiled and Leo Goosen and built by Offenhauser. First introduced for the 1941 Indy 500, the Novi was a quad cam V8 displacing 3.0 liters (to my knowledge the Novi was one of the 1st quad cam V8's) With it's trademark Paxton centrifugal supercharger (producing 30 psi of boost) and a triple carb set up, the original Novi cranked out 450 hp at 8000 rpms. Over the next 3 decades, the engine was continually developed earning a celebrity reputation with fans for it's unique engine note while simultaneously earning a widowmaker/car breaker reputation with drivers. Power delivery was unpredictible, with a surge of power coming on suddenly at high rpms….not a good characteristic at a track like Indy. The engine was so powerful and highly stressed that it frequently broke itself (usually connecting rods or pistons) or the car around it (driveshafts, differentials and tires). These factors lead to many crashes over the years with 2 fatalities.

        • scroggzilla says:

          The final incarnation of the Novi appeared at Indy in 1966, in a 4wd rear engined chassis developed by Ferguson and Andy Granatelli and driven by Bobby Unser. That version of the Novi displaced 2.7 liters and, with a 2 stage Paxton supercharger, produced a whopping 837hp at 8200 rpms. While the car showed promise, being far more stable than it's FWD or RWD Novi powered predecessors, it crashed in practice. While the Novi never won at Indy, it did set speed records at Bonneville and at Monza during the Race of Two Worlds. Karl Ludvigsen wrote the definative tome of Novi powered race cars and, as with anything he writes, it's worth a read.

    While working in western Kansas I saw 2 of the GMC V12s they were on natural gas on irrigation wells one on each side of the Smokey Hill River. This was mid 70s local folk lore claimed that they pumped enough water from wells under the river to dry up the river in 24 hours

    (Takes a while to get started, but when it does…)

    Also, I know they're lacking all the reciprocat-y bits, but as long as aero engines are being posted, I'll throw in the Pratt and Whitney J58 (off the SR-71 Blackbird) for an honorable mention. A hybrid turbojet/ramjet engine (by way of a variable-geometry inlet) designed to cruise above Mach 3, requiring custom high-temp fuel so stable the plane had to carry reserves of a special highly-volatile starter chemical (remember to make sure there's still plenty aboard, in case the engines "unstart"…), and needing a starter cart composed of two kludged-together Buick V8s to get spun up…all built with 50's jet technology. It was pretty crazy, all right.

      Sonofabitch, I forgot all about that one! Although with my passionate love for VW engines, I might just have to show that one some love in a separate post.

      • JoeDunlap says:

        From what I recall reading about it, while the concept itself was viable, there were major issues with heat buildup between 2 banks, as the exhaust from one had to be routed directly next to the intake of another. Of course, the ultimate expression of this would be to add two more banks and make it a 30 cylinder radial, LOL

  33. Does VW still sell the nutty VR5 engine? (Yes, VR5. It was like a VR6, less one cylinder.) They offered it in the Seat Toledo for a couple of years.

    Ahh, the Ford Cammer 427. Which produced a dialogue with NASCAR's Bill France something like this:

    FRANCE: You've gotta be kidding me.
    FORD: But it's developed from a production engine!
    FRANCE: No.
    FORD: But we can build 500 of them.
    FRANCE: Not just no, but hell no.
    FORD: Okay, then we're going home. Screw you!

    The original Cadillac V16 was prettier, though, even though the Marmon V16 was a more sophisticated engine for the time.

    • VeeArrrSix says:

      No… the VR5 went the way of the Dodo when they introduced the Inline 5 cylinder.

    • CptSevere says:

      I liked the later Cadillac V16, flathead, and such a wide V angle that it was almost a flat sixteen. That was the more successful engine as well, from what I've read. I sure wish I had a '39 Caddy with one. I'd feel like a cool dude.

Nevertheless, we can’t help but think there’s a slight flaw in their logic — besides the huge, glaring omission of the Volkswagen Group’s series of W-engines, of course. Many of these engines are very nice, it’s true; but they’re hardly what we of the Hooniverse would call “crazy”. Most of them are pretty tame, if you ask us. So while we think Jalopnik did a great job on their selection of engines you can buy today, the entire Hooniversal Brain Trust sat down last night and discussed this. Let’s have a look at what “crazy” really is …  Details [...]

    Probably about a 7 on the goofy scale, there is the Ariel square four motorcycle engine also. Good post with pics here.

    And there is also the Fairbanks-Morse opposed piston diesel used in submarines and locomotives.

    Where’s Mazda’s quad-rotary from the 797B that won at Le Mans in 1991? The FIA banned rotary engines for 15 years because of it, to allow piston engines to catch up in reliability. They never did catch up.

    And why the hell won’t Mazda allow the public to by the RX-8 with the triple rotary engine, at 450bhp? The Porsche 911 can’t keep up with it.

    Ford built a huge aluminium V8 that was fitted into tanks designated GAA. It's pretty impressive.

    Napier Nomad for extreme complexity and taking supercharging to its logical conclusion… http://en.wikipedia.org/wiki/Napier_Nomad

  • chris harris says:

    There are two great engines that you've missed. The first is the Napier Deltic diesel engine. In vertical section, the engine forms an inverted equal sided triangle. The three crankshafts are located at the corners and the engine is an opposed piston design. The engine was supercharged, most castings were aluminium and the world had seen nothing like it! Output was prodigious. It powered various types or large, high speed boats (for which it was originally designed) and Britains high speed main line deisel electric locomotives in the 1960's to 1970's. The second engine worth mentioning was also a Napier design this being the Napier Sabre aircraft engine. Designed in the early 1940's the Sabre was an alternative to Rolls Royce Merlin and later Griffon engines. Due to its mechanical complication, it was initially unreliable but improved over time: it was far an away the most powerful piston aero engine of its day with around 4000hp when fully developed but required rebuilding after approx. 85hrs flying. It was a sleeve valve design and the cylinders were H layout. A magnificent effort by Napier design engineers. Anyone wanting truly serious horsepower would need one of these…….if you can find one.

    • RWM says:

      That is ridiculously unfair lol, I read all the way to the bottom marvelling that no-one had put a Deltic in the list and feeling very proud of what I was about to post.
      The really beautiful thing about deltics is that with one crankshaft rotating the opposite direction to the other two they self-cancel all the primary out of balance forces in the dynamic part of the system, thus removing the need for crankshaft counterweights and reducing weight and internal inertia. The Deltic Rail Fleet that ran on the East Coast Mainline was 'guaranteed' for a fleet mileage of 4.5 million miles per year for their first 5 years of existence, as long as none of the 22 locomotives exceeded 220000miles a year individually, at the time they were truly revolutionary, and at around 100 tons for 3300 hp were a considerable advance on the class 40 1-Co-Co-1 s which had about 2000hp in a 130+ to unit.
      The engines need to be scavenge blown (forced induction) since they don't have any proper induction stroke per se, and some variants were turbo-charged, including the 9-cylinder version used in the EE type 2 'bably deltic' locomotive. The 9 cylinder deltic Engines were used mainly as auxiliary power units on naval ships, I believe that some of these units are still in use, but I'm not sure so if someone can back that up it would be great.
      There was a prototype variant of the 18 cylinder deltic with a gas turbine down the middle of the three banks running off unburnt fuel in the exhaust…according to wiki, this prototype produced 5600bhp on test before throwing a rod.
      I noticed that the article also links to something caled a Zvezda M503 which apparently was the equivilent powerboat engine from the other side of the cold war…nowhere near as elegant, or as nuts but worth a look all the same.

    What no mention of Harry Miller's Blown four cam V16s from 1931? 1100 cubic inches turning 6,000 rpm and making 1800 horse power. Two of them (total production) were commissioned by Gar Woods for his record attempt mahogany racer.

    hope you guys discover the napier delta engine 18 cyl 2 cranks

  • Oren says:

    I think I remember a design from Bill Lear: Delta configuration formed by three cylinders, three cranks (one at each apex of the delta, each crank connected to two pistons), and six pistons, two in each of the sides of the delta. Ignition at the center of a cylinder, pushing outward on the two pistons and driving two cranks. Can anybody confirm?

    • Ozz says:

      It was called a Napier Deltic.
      The "Deltic" Engine was developed in the 1940s by Napier & Sons of Manchester, England to address the needs for high speed naval vehicles. The resultant engine had an excellent power-to-weight ratio, was compact by marine standards and was used in a variety of marine vessels. Two units were fitted in the famous "Deltic" type V locomotives (later class 55) used on Britain's railways between 1961 and 1981.
      Absolutly mental 2 stroke diesel engine

    • jeremy fine says:

      Sounds like a Deltic diesel as used in the English Bush Locomotives of the 60's

  • Steve says:

    For sheer mechanical lunacy, the rotary radial (stationary crankshaft, engine rotates) aircraft engines of World War I have to be the champions. The Zvezda's craziness credentials are much improved if you know that it started out as an intended aircraft engine, for Tupolev's B-36 equivalent.

  • bigbill says:

    good old detroit 71 series 2 stroke diesels

  • Randy says:

    you forgot all the big one cylinder engines like the hot bulb and hit and miss. here is an example in application http://www.youtube.com/watch?v=ULQ6196Tfds&fe

  • jez says:

    laid hands on the Napier Nomad at the Smithsonian. one of two in existence. pretty exclusive cannot buy at any price hardware. bit of corrosion here and there but diesel power and an axial supercharger. Best of everything.

  • Chippy says:

    How come you haven't included the Napier Deltic engine?

  • Transexl says:

    As they are no longer built, barrel/wobble/swash plate engines do count, right?
    A quick search brought up this :

    What about the Lancia TriFlux enigine

  • cap'n fast says:

    I just saw tow of the strangest engines. the maritime world is full of strange things. they made engines very compact when designing for submarines. case in point: the agss albacore. diesel/electric research sub. main engines made by GM.16 cylinders 330cu.in per cyl in and X configuration, vertical crankshaft with the generator mounted below it. about 1000hp per engine(x2) main use is to recharge the batteries. main propulsion is two 7500 hp concentric dc motors driving counter rotating propellers.what a machine!
    you can lay hands and eyes on this beastie in Portsmouth NH, that's a real hybrid drive.

  • D Davies says:

    Being English, I'm quite proud that a lot of interesting engines were designed & manufactured in the UK, some of which feature here; however, presuming this is a mainly US site, I'm surprised nobody has mentioned the Nordberg radial 2-stroke diesels. Also there were a number of other US makers of radial diesels for aircraft, tanks & submarines.
    I worked for Foden's in the 60s when they were making a 12 cyl. 2-stroke turbocharged diesel: 9.6 litres, 440 bhp @ 2200 rpm & 1200 lbf-ft torque @ about 1300 rpm. It was for boats, & was two 6-cyl. lorry (truck) engines on a common crankcase with contra-rotating crankshafts geared to an output shaft – I suppose you would call it a U12 engine.
    Apparently Napier designed a square version of the Deltic, with rows of 4 cylinders. Also Rootes made a 4-cyl. version of the TS3, developing 200 bhp, but it was axed by the new owners, Chrysler, after only 14 were made.

    You can still buy a 427 SOHC engine. I know, we make them.

  • V24 Asti Spumante says:

    How could you miss the V24 Allison V3420? It makes some pretty hefty HP, Is very cool looking and rare, only 150 were made. I'd love to see a V24 in a car of some type. http://en.wikipedia.org/wiki/File:Allison_V-3420_

  • doviewiles says:

    I don’t think why anyone would even want to buy them. First of all they are very costly and second it’s not of any use now. Talking about engines, rates of engines are very high these days. So if you want to buy an engine you have to be rich, very rich. Or else the other option is to buy used engine which I did for my car. I bought a used engine and replaced it with my car’s old one. By doing this I saved lots of my money and got a fair deal from http://buyusedengine.com/used_engine.php Check out this place for used engines at nice price.

  • KingofGnar says:

    The Blastolene Peterbilt truck has a Detroit Diesel V12. They were manufactured by GM, not Peterbilt. A lot of non-GM trucks were equipped with Detroit diesel engines from the factory.
