What is the best piston layout and why is it literally V10?

10 is a nice number

you just need to remember how happy it made you when you had to divide or multiply by 10 back in primary school

it brings that joy back

>>14303350
Because it has the perfect Length/Width ratio for use in a performance car.

Probably the best sounding V10 on earth in my opinion.

6.0L V12
0.5L per cylinder, equal bore and stroke

>>14303414
although you clearly know what you are talking about i must disagree.
the idiotic, unbalanced, uneconomical and simply unlogical v10 has always baffled me.
untill somebody actually starts to argue that it is has functional purpose between v8 or v12. then you take it too far.

>>14303350
its actually the v6

>>14303366
do F1 v10s count?

itt confused anons

>>14303350
Either V12 (because perfect balance) or V8 (because nice packaging with good balance). V10 has the drawbacks of both: a long square to package it in, yet no perfect internal balance.

>>14303355
That's just because we use a decimal system. When using an octal or septal system, everything would be different.

>>14303373
Straight six a shit. Impossible to pack transversely (inb4 retarded Volvo engineers that took 2 decades to do so), and in longitudinal layout, it packages as well as a V12.

>>14303518
Oh, so you enoy making a massive suspension compromise? Good for you.

>>14303414
>equal bore and stroke
>not wanting an oversquare engine for mad rpm's and low piston speeds

>>14303562
V6 has shittier balance. Also, worst sound. For every good sounding V6, you can usually name a few good sounding inline sixes. Actually, only good sounding V6 is the Busso, and that's probably because it's a semi-hemi design.

>>14303562
I think you meant "straight six".

>>14303634
Straight six a shit. Retardedly long, which means your center of gravity is usually either ahead of the axle(where you don't want it), or the length necessitates a longer wheelbase(which is bad, m'kay?).

Now posting in the correct thread
>m-m-m-m-muh balance

Its not a problem in modern engines at all. How often do you hear stories of GTR engines shaking themselves to bits?
How often do you hear people like Mercedes HPP complain about the balance of the F1 V6? Come on, it means shit these days.

V6 is great for consumer applications. Smaller than a V8, can produce sufficient power with turbo charging and still keeping the packaging size down, they're more efficient that V8s and thus help keep emissions down when more and more stringent emissions laws are being pushed.

I love V10s, I love V12s even more, but I would be kidding myself if I thought the V6 wasn't a great engine for modern sports cars

>>14303626
You got it, Toyota

why the fuck does balance matter? is it a benchracer meme?

>>14303350

Superior to puny i4 and not a big fat pussyfart like v8.

>>14303626
>That's just because we use a decimal system.
And that is just because we have 10 fingers

>When using an octal or septal system, everything would be different.
Everything would be the same, we would just interpret it a bit different. If we had 8 fingers base 8 would be perfectly natural to us and counting by 10s would be less easy.

I wonder what out number system would be like if we were asymmetric al, say 3 fingers on one hand and 6 on the other.

Great sound, and available in great cars, but sadly, it packages horribly (second only to inline six), and doesn't offer any advantages anymore in a world where a 350hp inline four turbo is the norm.

Only companies that use flat sixes are Subaru and Porsche. Both can't use double wishbone suspension, nevermind a modern multilink, because of the added width of the boxer engine. They're stuck with MacPherson struts that have a shitty camber curve. All in all, you can definetely say boxer engines require suspension compromise on road cars.

>>14304527

>>14305943
Porsche doesn't use multilink in the 911 and Cayman. They use MacPherson struts at the front because they need the added frunk space, and a gimped multilink-ish strut at the rear, instead of proper multilink + shock combo. The only reason it isn't a true MacPherson strut is that they have seperate control arms down low for some added camber, but it's still a heavy compromise. Also, most of the early ones were still Macpherson+torsion bar, and it took several track increases over the years to get enough space for said gimped multilink+strut combo.

Subaru has been using them for cost, packaging, and the fact that that boxer engine is goddamned wide. Designing a global production car around rally spec is stupid. They could just use double wishbones on the road, and then adapt MacPhersons for rally use, just like Mitsu did. They just can't - packaging a boxer and true double wishbones doesn't work that way. If they could, they would. As would Porsche.

Aren't Group A cars suspension part of the homologation package? It'd have to be the same as the road car.

Which doesn't explain why the GT3 RSR now has double wishbone in the front.

>>14306242
Not him, but you're kind of right. Although while Mitsubishi stuck with the Group A formula into the '00s, Subaru hasn't competed a Group A car for almost 20 years. So macpherson strut being fitted for homologation purposes really doesn't fly.

no it isnt, its not any wider than a transverve inline 4 or 5, a subaru EJ is like 32.5 inches wide, a honda k20 plus transmission is like 30 inches
2 inches is nothing and several K powered cars have double wihsbones at the front

well they have to use production spec parts in Group N and other entry level leagues

lan evos have macphersons and as a matter of fact the 4g63 engine is like 22 inches, add the transmission and its wasily close to 32 inches

Regardless, I don't see how being impossible to pack transversely would be a good thing...

>>14309633
>the whole world uses U.S. "English"
Try again.

>>14309642
Some of the best powerhouse motors known are straight 6s. Specifically the 2j and rb series engines. Where they shine is big power, the applications they're used in really dont require "centralised" mass.

And if "I need to spell it out for you" I was implying front wheel drive, or traverse layout sucks.

>>14309668
That's all well and good, if making peak numbers and straight line acceleration is your goal (which VQ and VR V6s are achieving the same performance these days anyway).

I know what you're saying about transverse layouts, however the shorter option is still a better option for centralising mass in a RWD application...unless you only wish to go in straight lines.

>>14309684
My point is your original comment of >straight six a shit
Isn't merited. The 2j , although extremely overused, is a fucking monster especially for a stock engine. And the vr and vq come nowhere close to it in stock form. Although it's main use is really only for speed and power I'd assume as an auto enthusiasts board we can appreciate that

>>14309712
>straight six a shit
Isn't merited
Sorry for the confusion, that wasn't my quote. I picked up from a previous conversation.
I will argue the VR does come close, and eclipses the 2JZ in stock form however.

If V10 is such a great configuration why wasn't it used for aero engines?

V12 is the true master race.

>>14309720
Sorry, by stock form I was referring to stock block/ internals. On boost the 2j can handle some Rediculous power with factory internals. Obviously new motors will kick it's n/a power output as its reslly getting old now.

>>14309712
>>14309684
TVR speed 6 is alot better engine, no rb or 1/2j makes 400hp n/a stock and its in a car the hadles indefinatly better than the pigfat supra and skylines

>>14309764
I meant the same thing.
2JZs can handle up to ~8000hp and still maintain a degree of longevity. VR38s can achieve at least that.

>>14309771
The point of hostility is?
Sounds like a great engine though. I wonder how it will hold up with 30 psi on it.

The extra smoothness is nice, but the stress on a really long crankshaft like that can damage the engine.

Straight 8's are still top tier though. There was a time when they were the premier racing engine.
