All that unnesassary friction... No wonder an archaic North American V8 puts out more power in a smaller, simpler package. I can see why VW struggles to get 350hp out of a NA V8.

These engines are desinged to handle continuous driving with high speeds.
These chains don´t add much friction to the engine and since they aren´t that long they won´t jump over after some thousend kilometers.

Technically it is actually more complicated but it's all in one place.

Indeed, but a single belt for a V engine isn´t very relieable since the belt wou need to be insanely long.
>>
>>16273437
The Audi V8 was designed to hang out ahead of the front axle, so it had to be as compact as possible to no completely fuck the weight balance. The chain-driven one is only like 18" long.
This means they had to use a tiny bore and relatively long stroke, which pretty much gives it the same problem as an old Chevy 305. It does of course use 4 valves per cylinder so the heads aren't as restrictive, but it's still a design weakness.

Look at that retarded one on the bottom all bent over itself.
That alone is completely unforgivable. Don't even mention the rest.
Some fucking autistic cunt was so sure that chains were superior to gears or ANYTHING ELSE he was willing to stake the well-being of Audi's reputation on it. Then Audi cheapened out, making most of it out of plastic. FUCK THEM ALL. At least the Chinese have an excuse for being this shit.
Look at the Northstar's timing chains and tensioners.

How much does that Audi V8 weight? I bet it's as much as a iron block truck LS.
>>
>>16273550
Apparently it's like 360lb with most accessories, and that's for the older, bigger, belt-driven ones.
>>
>>16273546
>plastic tensioner
No thanks. Even Honda got it right.
>>
>>16273546
The INDIVIDUAL chains aren´t that long, wich is why they won´t jump over even if the tensioners are worn out.
Also they are made out of polytetraflouethylene wich is one of the materials with the lowest friction and wear known to mankind.
Also if the pressure (force persurface) on the tensioner is higher it wears out faster.
>>
>>16273570

Closer to 470 if you want one capable of running. The block without fluids and only a bit of the bullshit is 360.

Pointless when a aluminum block LS is lighter.

That shit doesn't matter, unless you're running a fucking retarded drivetrain layout like audi. That entire engine is completely and utterly pointless, an abomination that never should've seen production.
>>
>>16273613
These engines rev pretty high, this one has it maximum power @8250rpm, so the chain tensioners must be able to keep the tension as high as possible withou having to much wear on them.
>>
>>16273602

I haven't seen any direct comparison pics but I'm pretty sure the Audi V8 is longer, wider and way taller than a LS.

>>16273592
It has 9,7l of oil (0,8-0,9kg/l)

>>
>>16273646
It is more like 40 lbs
>>
>>16273646
It came to 180kg for: -
Block with crank and pistons
Heads complete
Inlet manifold
Exhaust manifolds
Alternator
Belt covers
Starter motor

It didn't include
Flywheel
Clutch
Wiring loom
Coil packs
fluids
PS pump
Air con pump

So a figure of 215kg all up sounds about right.

..........Pigfat.........
>>
>>16273591
The chain may not jump when the tensioners are worn out, but the chain will still rattle around and make contact with the block. Personally I would rather have to deal with a jumping chain then a chain eating the block away. The even bigger issue is even before the tensioners fail all the way the chain will get slack in it at idle and start to munch on the block. The only reason to buy a car with the 4.2 V8 is if your a massicus

Alright, from forum posts:

(older belt-driven V8, chain-driven version is 2-3" shorter)
2001 AKB dimensions:
Bottom of sump to top of black plastic valve thing on top of intake manifold: 26"
Bottom of sump to top of intake manifold: 24.5"
Left timing belt cover to right timing belt cover: 30.25"
Front of crank pulley to bell-housing face: 20"
Front of snout on fan pulley to bell-housing face: 21"

GM LS1/LS6

Width: 26 inches wide
Length: 28 inches
Height: 25 inches
Weight: 425 pounds

The LS isn't really any shorter bottom-to-top, 4" smaller side-to-side, and 7-8" longer front-to-back.
>>
>>16273687
If the chain jumps over the pistons are eating the valves...
>>16273690
That is a intersting idea, but 4 bearings on the front of the engine would make it even longer.

>>16273723
A chain or belt can normally jump a couple of teeth and not make contact with the piston but you will have some very major symptoms when they do. Even if the pistons did make contact with the values it would still be a easier fix then replacing the whole engine due to the stupid timing chain eating it. When that timing chain starts to go into the block it sends all kinds of aluminum into the oil system which can cause bearing failure and score up cylinder walls.

The 4.2 v8 just has one too many critical design flaws in it to make up for any advantages that come with it.

Don't even get me started on how it likes to carbon up the valves and that alone can lead to bent values.
>>
>>16273827
Since there are hige tensioners everywhere it won´t eat up the block.
Also the carbon buildup might depend on your oil, fuel and driving distance and speed.

Also it´s specific output is pretty good.

i hear people complaining about them but never see a reason why

pushrods are proper design. they allow for a single cam. dual cams were more of a japanese auto industry gimmick, it was easy to fool people back then. one automaker would have the dual overhead cam which was a supposed advantage so people thought engines without dhoc were inferior. there was some kind of false japanese superiority involving dhoc


dual cams add needless complexity for minor performance gains. the added materials and machining are not worth it. the late 80s and early 90s were a very stupid mess for the auto industry.
and people who hate on pushrods are always either mexican, filipino or some variation of mexican/asian minority "culture"

The LS/SBC scene is so unbelievably overdeveloped it's ridiculous. Any thing possibly that can be done to a merican V8 has been done. Burgers like to use this as an argument about superiority, when the VAG V8 is always an objectively better piece of engineering, and built much better too.

(D)OHC can change the valve ltime AND lift

There is a good reason most high performance engines, like for Le Mans or formula 1, are DOHC

We had 400hp V8's back in the 70's you know right? People were running 13:1 compression back then, Which you euro's are just discovering now.

you can change lift with a cam
variable lift is not really desirable as the timing

either way, you are totally missing the point of why multiple cams with multiple timing systems (including lift) is a very bad gimmick.
the real world performance gains are not worth the added cost to the consumer.

its totally a bad 90s gimmick which has never been stopped because engineers wank eachother even if their ideas are bad, and mexican people are too stupid to know better, so they project their stupidity like fan boys would do.

pro tip: 5 valves are definitely not superior against 2
>>
>>16275382
VVT literally only exists to avoid getting cucked by emissions regulations, it has nothing to do with performance. It just makes the valvetrain more prone to failure and harder to service.
>>
>>16275360

So your multi million dollar engines were competing with some high school kid working in his garage after school? Much advanced. But what do you expect coming from people who thought using old ass engine blocks and pissing on new ones was a good ideas when building a race engine.
>>
>>16275382
With VVL you can have multiple cam profiles for different rpms wich gives you a better torque curve and fuel efficiency.
since you won´t just gain performance, but lower the total cost of ownership DOHC is worth its initial price.
>engineers wank eachother even if their ideas are bad
Nope, If you deliver shit you might get fired soon.
>mexicans
What role are mexicans playing there?
5 valves have a much higher skirt are and a lower mass, so they will work up to higher rpm and have a better flow.
>>
>>16275416
But 5 valves and VVL/VVT add unnecessary complexity and cost to everything, and you don't need revs if you've got enough cubic inches/torque.
>>
>>16275407
There is no multi million dollar engine ITT, the Audi V8 aren´t that expensive.
Also it isn´t only focused on power, it also has good emissions, lasts long and needs about half the fuel of a burger V8.
>>
>>16275396

no, you dont need a variable timing system for this.
wrap this around your fucking head.

you can achieve middle ground with stationary timing just fine and scrap with extra $1000 in engine cost to the consumer

vvt is installed on civics and all kind of economy cars which is a total waste. it would only be feasible as a performance machines, to gain performance rather than fuel savings. which also fits role as a performance option in the first place.
yes vvt can achieve fuel savings, but its only a marginal gain. its overall use is much better for speed, rather than economy

>>16275431
They don´t make it much more complex, the most complex part of the Engine isn´t the cylinder head.
The add power and efficiency.
>>16275439
At low RPM you want a different cam profile than on high rpm to have a high output at high rpm and on low rpm.
>>
>>16275434
But you can achieve the same power figures with a more aggressive static cam, and more reliably too. I was agreeing with you that VVT is a fucking waste of money and resources and a typical eurocuck """"feature"""".

A 7l V8 with a big ass cam will still have no problems destroying the tires at less than 2000 rpm.
>>
>>16275467
A 7l burger V8 with big cams will need a oil platform in the backyard if you DD it at high speeds...

>>16275500

You've been brainwashed into thinking big engines equal worse fuel consumption. A big burbling V8 at 2000rpm is using less fuel than some high strung turbo 4 at 4500rpm.
>>
>>16275514
Only cucks care about fuel consumption, gas is cheap in the relevant part of the world.

maintaining multiple instances of variable timing on multiple cams is a very stupid idea. whoever forced these practices into standard production needs to be fucking shot

emissions efficiency is mostly achieved at the cat. and with raw materials used in frame/body construction and engine assembly. compression is another major factor, probably moreso than anything else. timing plays little role.
economy cars dont need variable timing or lift. they can be tuned to idle and play around 3500 rpm with a single cam with static timing just fine.
it wont make them run like slow shit. nobody would even know the difference

only idiots are paying extra cost for junky unreliable systems and they believe their engines are not garbage, but pushrod engines somehow are, which is immensely stupid

its a total auto industry sales gimmick. it went out of control because of marketing, not real engineering
>>
>>16275519

If both are putting out the same power the turboed DOHC 4 cylinder usually needs about 230 g/kwh, the OHV V8 usually needs about 300g/kwh.
>>16275520
If you drive over 100km at high speeds it matters, even if gas costs 2$/gallon.
>>
>>16275532
g/kwh
what the fuck kind of cuck units are those
>>
>>16275525
I didn´t say it changes the NOx or HC emissions, but it changes the fuel consumption drasticly.
Also economy cars don´t always rev 3500 rpm, tey usually rev 1500-5000rpm due to different speeds and accelerations.
>>16275541
This is the usual mesurement for ICE efficiency.

It was started by moot, based in the states, it's literally a fucking U.S. board, always has been, just because a gook bought it doesn't change anything.
>>
>>16275572
It changes the fuel consumption especially if the engineload isn´t constant since you can run the atkinson cyle if low pwer is needed and the otto cycle if you need the full power.
Also you can run a high rpm cam profile and a low rpm one to have a better powerband.
>>16275579

Quality thread once again lads.

Cheaper to maintain than an American v8? Gotta be the funniest thing I've heard all week, good one! I've seen small blocks last 450k before the tranny dies, or the subframe rots out, and the only maintenance was oil and spark plugs. My last car had a SBC TBI, I got it at 300k, and sold it at 395k after the tranny sploded.
