weirdly - it's gotta be American


V16 baby, so big yet, so graceful and elegant... Love this thing's looks

Ferrari 312 V12




Awww man!!! I feel so left out. Wait... It's not my fault. That is so demo - descrimination. C'mon man!

Hah... Even though FAKE petrol heads are not supposed to post here (only REAL ones), I did! Hah! Lol...
1/4 ferrari, RUNS!!!
It might only be a 1.5, but you can't deny that a lot of time and effort has gone into making it look like this:



Although whether the guy actually drives it anywhere is up for debate

Quote from tristancliffe :First law of cool engine threads. Don't post pictures of conrods that are made wrong. Save the above for the "Budget engine thread".

made wrong? howso?
Just like 99.9% of production conrods, the i-section is in the wrong plane. Look at a proper conrod (e.g. F1, because it's easy to find pictures of F1 conrods) and see how different they look when made properly.

And having a cheaply made, compromised engine defeats the points of a cool engine thread.
i see what you're saying tristan...

but why do they make them this way instead of that way, if that way is better?
Cost! Easier to cast them. Presumably the i-section is kept (albeit in the wrong plane) a) to reduce reciprocating mass and b) because people want to see i-sections, and are mostly too ignorant to realise that it's not actually doing any good at all (other than weight). If anything, those conrods end up heavier than they need to be for the strength they end up at.

Forged conrods are usually correct - unless they were designed by an eejit. And sadly more and more eejits are employed by large firms, so more and more things are being made wrong. And it's not even like it's a difficult engineering concept!!!

I just can't see how a modern engine, made to a cost, with only 4 pistons and 50hp can be allowed in a cool engine thread. Surely, like the game Top Trumps, it needs to have at least one big number associated with it. 16 pistons, or 1000hp from 1.5 litres, or 15:1 compression ratio (spark ignition only), or 1500 race victories.... But when an engines best claim is "went to supermarket last week" it can NEVER be cool.

spose..but at least the 4A doesn't have a cooling system deadspot on cylinder 3 like the 3S ;D
Neither are cool anyway*, so it's a moot point. And we haven't found cooling on any cylinder to be a problem anyway, so that's a moot point too.

*they were used in boring road cars, aren't very powerful, don't have many cylinders, don't have particularly high BMEPs, are made to a budget and don't sound nice. Oh, and they can't be balanced properly.

i consider an engine cool, if its well engineered enough to be used often, at it's limit, and not require parts replacement often (new GTR engine needs that "plasma" bore liner replaced quite often iirc, can't see that as being a cheap job)

so eh, it's all about your definition of the word i spose. I mean an enzo engine is kinda cool, till you realize it needs a major service if u drive it hard a couple times.

5 Cylinders, all moving independantly - perfect balance. 5 seperate ignitions per revolution, as opposed to the 2 seperate ignitions of a 4 cylinder. A work of genious.

Game, set and match!

Definitely not one of the best looking cars ever made but it's four-cam, 24-valve, normally aspirated 3-litre V6 had a power output which was quoted at 410bhp at 9000rpm! Something which made it one if not the most powerful, natural aspirated rally car ever.
While we are kinda on the subject of engine internals and stuff, i have a little story to tell.

When my uncle used to do autograss racing in a mk1 escort, he raced in one of the more standard classes, whereby all engine internals had to be totally standard and the cc limit is 1300cc, and when building his engine he did a little experiment that paid off.

He bought many many sets of off the shelf standard parts, such as valves, valve springs, pistons, conrods, etc, and then preceded to weigh them individually.

Now i can't remember the differences exactly between parts but out of all the bits that he had bought there was a considerable difference in weight between parts that were supposed to be a set, but once he went through lets say 5 pre packaged sets, he then had his own matched set that were near on identical (and the lightest) in weight.

He then built the engine with all these weight matched sets of parts, and the result was 6bhp more on the rollers than any previous engines that he had built, (only 1300cc engines remember) and where he would normally finish 2nd or 3rd in any given 6 lap race, with the home balanced engine he was regularly finishing 1/4 to 1/2 a lap ahead of everyone else!

Cool but if you take into account the fact that's it's a 8 liter, quad turbocharged engine, it's output of 1001hp is not really that impressive.

How do the pistons move independantly? 5 separate cranks? Any why is five ignition pulses (i.e. not wasted spark) clever? The only reason wasted spark exists is because of cost, but it's the work of an evening to convert it to a coil per cylinder, or to use a distributor.

Quote from GAVD999 :this has got to be up there

Why? Throw enough turbochargers at an engine and you make whatever power you want. Aspects of the Veyron are impressive engineering feats, but I don't think any of it is particularly cool - have you seen how much that thing weighs?

Blueprinting an engine is an eay way to find power. It works, it doesn't reduce reliability, and wins you races. The devil is in the detail.

Is it still cool when working it at it's limit is still a tiny amount of power? Is any engine cool if it manages to do 250,000 miles? Or is that just because it's understressed, or well designed. And is well designed cool? Are Miura's cool - because they aren't well engineered. Is a Passat cool - because they are well engineered.

Cool is very subjective. I don't think any engine in a hatchback or repmobile could be cool, and I don't think making a powerful engine from a huge displacement with lots of turbos is cool either personally. Having said that, age has a lot to do with it - a Mini with an A-series engine is somehow quite cool, despite the fact that, in reality, they're a bit crap, are made cheaply, and aren't very reliable/powerful/interesting/tuneful.

Having said all of this, I've just realised it's not the cool engine thread, but the beautiful engine thread. So maybe it IS more about engineering - although engines with cast internals, a bit of garish epoxy paint on the cam cover and some blue hoses surely isn't beautiful? Unless that same person considers fake tans, breast enhancements and false teeth beautiful on a woman...
