What on earth are the benefits to a w8 setup aside from packaging?
I think they sound absolutely incredible. Unfortunately they are insanely expensive to maintain, coupled with the fact that its difficult to find anyone who even knows how to work on them
Time to bring the thread back from the dead with a twin turbo flat twelve.
Austin Watson
I know this is an airplane engine but I figure it's mad enough. It's like a piston engine that feeds and is fed by a jet

This was beyond nuts

Now that is what I call a fucking rocket sled.
mid-mounted in a Forrester when?
Colton Myers
Wait so two cylinders share the same chamber? Thats pretty damn cool.

Post results please and be carefull with the A/F ratio, a little too rich and it detonates.

Honda asymmetrical V-5 engine. 3 smaller pistons on one bank, 2 larger pistons on the other bank.

>wankel issues >russian reliability Please, god no.
Cameron Peterson
Read the article years ago, they heat the intake gases and run lean like 18:1 or 20:1 or something. Pogue carburetor is worth a read too.
Nicholas Adams
>lean like 18:1 or 20:1 He actualy ran way more lean, araound 1:30
Connor Evans
Oh, it's been 7-8 years since I read about it.
Luke Morgan
What did this go into?
Austin Phillips
Looks like a motorcycle engine
Charles Myers
12 rotor lmao. Fuel economy is probably measured in angstroms Motorcycles
Robert Campbell
Mid-mounted in a literal wing on wheels good enough for you?
Julian Morgan
It was an actual thing. Those were only in the use of KGB or police. Ultimate unreliability combo.
Robert Johnson
>get chased by KGB >KGB stops due to engine problems TOPKEK
Jace Rodriguez
The W8 was kinda like VW's test-bed for the W-config engines, and was actually a really smart idea since it reduces engine length (front to back), which is critical in cars where the engine is entirely ahead of the front axle (like the B5 Passat). Now for an engine that's really damn hard to justify, the VR5. Same inherent issues as a VR6, not really any smaller or lighter, equally thirsty, but with less displacement, less power and worse internal balance. Fucking godlike sound though.
Kayden Diaz
What is this pic
Levi Rodriguez
It goes with out saying if you were lucky enough to get a car in Soviet Union. You had to wait about 10 years to get a car in the first place. Oh well, if it were to fail, then you are trying your luck since GAZ-24 with V8 would be chasing you
Jayden Kelly
See Ivan, when KGB arrives, get in Melkus.
Anthony Green
Speaking of God like sounds, that flat-plane crank made that W8 sound mean as fuck
Isaiah Gutierrez
Yeeah, sadly it's also the reason the thing basically shakes itself to pieces.
Hunter Wood
>Melkus RS 1000 is a sports car >powered by a 3-cylinder 2-stroke 992 cm3 engine similar to the one in the Wartburg 353 Uh-oh. The chase would be too long...
Jayden Diaz
>Melkus has perfect ballance >Melkus is verry aerodynamic >Melkus has increased power It exceeds 200 km/h, wich was a lot in eastern germany...
Lincoln Cooper
Meh, I didn't say it was reliable
Connor Brown
Ahhh that sounds mad as fuck
Benjamin Hughes
I heard stories of them catching Beemerfags in early 90's, though one can imagine they did not last long in service after SU fell

Anthony Phillips
Production when?
Jack Sanders
shit, that dizzy
Colton Taylor
Even though it was shit the BRM H16 was a pretty cool engine.
Grayson Scott
Honda RC211V MotoGP motorcycles. Basically it was a gimmick to exploit FIM rules. At the end of the '02 season they re-wrote some of the engine spec rules. Basically a V5 could be far more powerful because it fell into a grey area in the rules, which set max displacement/rpm/etc using a tiered hierarchy.
Caleb James
Napier - those guys must have been absolutely nuts. Amazing stuff.
Anthony Morgan
what is this mechanical monstrosity
Samuel Thomas
That hot air engine wasn´t Napier, it was some guy in his own garage. A opposed piston 2-stroke engine.
Josiah Allen
yeah it's forced induction so who cares about pressure drops, right?
Jaxson Ortiz
I misclicked. Meant to quote
Caleb Young
jesus fucking christ what kind of ungodly mechanical monstrosity is this
Julian Martin
>afterburner >in a diesel >that has a 3.5 c.r. >41 litres yay for efficiency
Luis Gray
can someone post that pic showing how the heat is dispersed in a W engine compared to a V engine?
Jeremiah Cox
Actualy the deltic was a german design by Junkers...
Ryan Fisher
actually, it was among the most fuel efficient aero piston engines
Blake Johnson
That'll do pig, that'll do.
Oliver Hughes
Honda has a history of doing unusual stuff to get around regulations. Pic related, it's the NR750 V4 engine which has oval pistons and 8 valves per cylinder.
Jackson Hughes
>they are insanely expensive to maintain, Explain why this configuration would be expensive to maintain.
>coupled with the fact that its difficult to find anyone who even knows how to work on them Why would it be more difficult to train technicians on this engine that a V8 or V12 for example.
Back your answers up with facts, please
Methinks you are talking bullshit
Lucas Ramirez
Not him, but it's probably expensive to maintain because spare parts for an uncommon engine such as that are probably pretty expensive.
Because they are rare, hardly anybody has bothered to train technicians specifically to work that engine.
Jackson Long
Oink
Mason Jenkins
It's not all that expensive to keep running compared to similar VW's. >Not him, but it's probably expensive to maintain because spare parts for an uncommon engine such as that are probably pretty expensive. It shares many parts with other vw engines, especially externally, and cost for any specific part is not out of line with other vw models. >Because they are rare, hardly anybody has bothered to train technicians specifically to work that engine. They don't need any specific training. Most techs have no model-specific training of any kind, and don't really need any. Decent basics plus very thorough manuals and documentation eliminate the need. >Methinks you are talking bullshit Youthinks correctly, fellow anime poster. >difficult to find anyone who even knows how to work on them No, it's not. Go to the fucking VW dealership. They are all prepared and qualified to work on them. They don't charge unreasonable amounts of money, people just have unrealistic expectations about the cost of major repairs, or really anything beyond the most basic maintenance.

Funny, my w8 passat was 7300 bucks to change the oil filter screen. I would consider that rather unreasonable.
Jose White
Oh boy do I have a site for yall. Be prepared for the cutting edge of 19th century IC engines.
>for most cars independent shops can do better work at lower prices >it's not expensive to maintain, you just have to go to the dealer
putting the moron in oxymoron
Angel Johnson
does this count?
Jason Brown
log manifold a best
Mason Garcia
do you have a boner for the w8 or something? because you're trying really hard to convince everyone that its basically the same as a corolla engine in terms of cost and ease of maintenance, which it abso-fucking-lutely is not
Jose Brooks
good thing flow doesnt matter when you're essentially raping your combustion champers with compressed air and additional fuel
Leo Morales
Did this type of engine go into any production vehicle? How does it called anyways?
David Martin
Now this would have been an adventure to maintain
Carson Turner
Seconded. I’m far from an expert on anything but it seems like there’s a ton more block material in between cylinders than there is normally on other configurations
Nathan Martin
it must have the same problem as the aerial square four and triumph square four .eg hot spots between cylinders
Less efficient than a 2 cylinder in-line with less reliability... W H Y
Ian Kelly
Those were primitive air cooled junk made as cheaply as practical. I collect and ride old Britbikes and would love to have an Ariel for the art value, but they were not highly reliable machines even for their day.
Triumph square four? What Triumph square four? A prototype? They never mass produced one and in thirty years plus of working on motorcycles I've never heard of such a thing, not even at the Barber museum. Turner designed engine for both marques.
Liquid cooling solves the hot spot problem.
Wyatt Diaz
>The clapper
Aiden Wright
The single-rotor engine never made it past an experimental batch. Police interceptor Ladas were fitted with later 2-rotor engines, which weren't all that unreliable on the road, but needed an overhaul every 30-50k km.
V8 Volgas weren't made for chasing common criminals. They were made for tailing foreign diplomats who drove powerful imported cars.
Xavier Mitchell
>3.5L rear mounted V8
>air cooled
Joseph Stewart
first square engine I saw was in a triumph frame most like a coincidence
Owen Barnes
That's the huehueland version of the good old EA827, right?
