Now that the dust has settled, can we all agree that this was a meme engine that answered a question no one asked?

tfw dream car is an rx7 fc, all in the area are rusted to shit or need some serious love. Would it be worth it to import? I'd prefer LHD since RHD insurance in Ontario is murder.

think about you big dumb dumby

one has weight that goes up and down

one has weight that only goes around and around

no that hard to figure out why pistons are inherently flawed

Come on Veeky Forums, let's put our heads together and figure out how to fix the apex seals problem.

I'll start.

What if they were made from carbon fibre? And what about an extra oil tank with a gauge to warn drivers when it needs topping up?

>get aftermarket ones designed to hold the abuse
>premix
>done

wow that was hard

It would make sense in a sub 2000lb sports car but at that point a 1300cc motorcycle engine makes more sense.

Why you would want a rotary in a almost 3000lb car is beyond me. Like hp/l matters at that point...

Why do you hate mazda?

ceramic apex seals are basically perfect, the main problem is the omp that doesn't get enough oil in there

Cosmo was a big car but the 20b is a powerhouse
Mazda roadpacer was a full sized gm sedan with a 13b, horrible gutless vehicle

but the problem lies in the way of thinking that you have adopted.

mazda have been trying to fix an old design for ages. same materials for all the major components, different design and materials for the seals.

redesign the whole thing. find metals and processes that work together well.

I dunno....I've been taking good care of my FC for a few years now and it's both my daily and project.
There are aspects I wish were better, but I can't complain too much.
Fuel efficiency isn't that much of a problem for me because I don't go riding the red lines when I drive to work and back.
Performance-wise, I've been able to push it to a good limit on windy roads and tracks, but am still limited until I finish building it. Kept some good pace against newer cars, but that can probably be attributed to driver skill.

I'm not sure what there is utterly hate about rotaries engines. They're not BAD, but they not the greatest either. I guess like most other things, this is really subjective based on your own preferences and (especially) experience with driving/working on cars.

People hate rotaries because they are clueless bandwagon retards who read on a YouTube comment that a rotary gets 4mpg and lasts 40k miles and believe it as fact

>support people saying rotaries are shit,
>demand goes down
>rotaries are cheaper

nice, its kinda like socialism

>tell workers socialism doesn't work, muh white genocide
>can exploit them all I want
>I am a job creater after all

I love stupid people

Actually I think rotaries would be a better fit for bikes.

> lightweight
>bikefags are more likely to take good care of it, plus on a bike it's easy to access
> super smooth ride
>power and BRAP

Why not?

There's been a bunch and they didn't sell well

visordown.com/features/motorcycle-top-10s/top-10-wankel-engined-bikes

A Busa engine with a turbo weighs less, puts out more and is more reliable than a NA 13b.

Not worth it.

This
Bike engines have so much more development put into them compared to the wankel
Also like 30 years of advancements over the 13b...

13b isn't really designed for bikes though
it could be smaller and rev even higher (think 20k+ rpm)

Did you seriously just mistake power/weight for hp/l? Theyre completely different things. Power/weight is what makes them nice performance engines in addition to revving sky high, they're just hard to justify in a street car.

By the time you shrunk one down enough to fit in a bike you'd be still better off with a piston engine. The rotary hp/l is actually less than a bike engine and that's only going to get worse the smaller you go.

> The rotary hp/l is actually less than a bike engine and that's only going to get worse the smaller you go.

this depends on the size and rpm, so how would you know unless someone made a comparably modern rotary designed for use on a bike?

No one has the money

freedom-motors.com/freedom_530cc.html
this company claims to have a ~500cc rotary making 80hp

One of those engines is missing a load of parts and torque.

Rotaries exist in all sizes from some that fit in RC planes to some that are used in light aircraft. They're still rarely used because they're not as good.

This company claims to give people abs in seconds

they're used in aircraft pretty often actually
but you wouldn't know that because you're a dumb shitposter on a shitty image board

You're thinking of rotary configured piston engines. Wankel rotaries are almost never used.

Source: pilot

They are used in a variety of light aircraft
Source, I like rotaries

no, i'm not.

those are radial engines

Plenty of LSAs and kit planes use wankels.

Think about it.
The way pistons work is built around a violent reciprocating motion, converted into rotational momentum via the crank which delivers power to the wheels deliver power to the wheels.
Rotary engines ONLY use rotational motion, so you dont have a violent reciprocating piston slap where energy is lost and stress is put on the crank shaft.
Overall you have less weight in the rotating assembly, which means less vibrations and quicker throttle response.
Due to the engine design it makes catastrophic engine failure a nigh impossibility, and you're guaranteed to have smooth power delivery.
There are many positives to the rotary engine over a piston design, but the problems plaguing its reliability are ones that really only affect the consumer market, not the enthusiast market, which is why its been phased out.

lol no

a busa engine is around 170lb without a transmission, an aluminium 13b is 109lbs, a turbo busa is way over 200lbs, a turbo aluminium 13b isn't

plus a turbo 13b can make over 1200hp, something a busa can't

cuck'd again

>torque

try not being an amerifat

>delivers power to the wheels deliver power to the wheels.
whoops

Sorry I'm a bit new to cars but from what I've seen across a few different enthusiast websites is that rotaries are disliked because of their emissions and fuel economy. Well excuse me but that seems like an irrelevant complaint about an engine that serves no purpose outside of performance applications.

What's next on the list of things to hate and why. The geo metro bevause it has 60hp?

Well the geo metro will run forever even with you neglecting it and beating the piss out of it.
Rotaries require diligent maintenance, and considering most normies wouldnt know they're supposed to get their oil changed if not for the pretty orange light that pops on to tell them so, they wouldnt do it.
Therefore its easy to see why a fickle bitch of an engine like the rotary isnt made any more.
The people that love the rotary love it because it does so many things right, and its such a cool design, but it just doesnt work well for a consumer driven market.

Great idea on paper, terrifying in reality because of wankels' inconsistent power delivery.

>inconsistent
What?

wankels have super smooth power delivery though, why are you talking about things you know nothing about

Even if they were reliable which they're not, It's just such a gay design that it can't produce and torque or even handle forced induction.
Pistons are so much better.

109lb just for the casings, no internals or ancilliaries

>muh tork
sry its not a diesel

>muh forced induction
??

Ugh weaker than a NA LS V8 and with a turbo that big it's going to weigh almost as much as a V8.

>cant handle forced induction
You are a retard.

Yeah, socialism has worked in so many states.
Inb4 they didn't do it right.

It's a good thing you're a nobody.

Wankels are dumb as shit and any wanker who likes them is dumb as shit too.

Unless you last name is Wankel, then I guess you have to shill your shit for shekels and pretend Wankels are good for something.

muh tork

muh tork

Top kek that image

Yes, keep working, i am the job creator after all

youtube.com/watch?v=bUBhJM2An34

twice as much power as an ls1 roflmao

I would say that they can be just as reliable as /most/ piston engines.
*Not* all.

The most reliable piston engines are still going to be more reliable than the most well maintained dorito engine.

The most reliable piston engines will last 400k, even 1mil+ miles with basic maintenance. The most reliable NA rotaries, well sure over 200k, 300k, which is great and better than tons of pistons, and changing oil and not overheating it is much less maintenance than lots have like changing timing belts and shit, but still that's nothing compared to the most reliable piston engines.

There is more that can cause failure in a rotary engine than the apex seals. The housings can expand and you lose compression even with the apex seals fine.

...

...

...

NSU fixed theirs to last 200.000 to 300.000km in the last version of the Ro80.
As said they have to be ceramic, NSU made them out of siliconcarbite in the last engines.

I love how >muh fuel economy is suddenly relevant whenever someone wants to shit on rotaries but never when amerifats ramble about their bigblock v8 muh best engines in the wurld.

>tfw RX-8/7FD gets better mpg than most V-8s

>implying a Turbo 13b with 520hp gets the same economy as a LS7 with the same power
wew

Comparing one of the best V8 engines with billions upon billions of dollars spent in engineering it from, at the time, the largest car manufacturer in the world, to an underdeveloped engine that was only developed on a shoestring by one of the smallest manufacturers, is... fucking retarded.

Yeah, rotaries are so bad they had to ban them from Le Mans ;^)

>rotary
>banned from LeMans

The engine itself was never banned.

Yes, they were. I think the ban was since lifted though.

Holy shit that's cute as fuck. Does that function?

It's a rotary, what do you think?

the ban isn't lifted, LMP cars must use reciprocating piston engines

> Implying I'm a wagecuck
> Implying I'm not livin off the gibs
Get out of here you dirty kike bastard

It's a drone/UAV engine. Wankels get thrown into drones and light unmanned planes literally all the fucking time. The only people using pistons at that scale are modelcucks and RCfags.

>150lb engine making 1,000hp
>bad idea
I found the real meme.

>a failed engine design that delivered poor performance
Yes, but Mazda is working towards developing one that actually works, weather or not it happens it a different story. In all reality they should focus on electric instead or dated ICE; it's the future.

>trying to race with an rx8

Like trying to fuck the clouds

>doing it for more than 3 minutes
>needing to add oil to your fuel like it's a weedwacker
>needing a weekly subscription of apex seals, crates of them

Found the real meme

They used a engine like this in le mans and the engine was in a pretty good condition after the race.

isn't Mazda working on a new rotary? I remember seeing something about patents being filed.

I really like the idea of rotary engines, I hope future materials can make it more comparable to modern piston engines in terms of reliability and maintenance. Super smooth and able to wind iout to high RPMs are great benefits, and I've always preferred high-revving motors on sports cars

1. they did announce a 1.6 turbo
2. ceramic apex seals dliver the same reliability as piston engines

did the renesis have ceramic apex seals?

Nope, the late Ro80 had them, it was able to get 300.000+ km (200.000miles) without significant compression loss.

so what downsides are left?

Still have to add oil to fuel, still have to redline daily to clean carbon?

You don´t have to ad oil to the fuel, there is a small oilport in the housing where the ECU controlls the oilflow.
You don´t have to redline it, but it has to get a decent temperature at least once a week.
Here in germany that ain´t a problem, but in burgerland you might get in troubble with a big rotary.
A rotary/electric hybrid would be the way to go since it can utilize the wankels high specific output at about 80-90% power output and can charge its batterys while getting the wankel to the desired temperature.
Also you won´t have to get the engine warm to use a decent amount of power with a hybrid.

wtf i'm #wankeling now

Instruction unclear, dick stuck in trochoid housing.

>in the face of facts... implement the underdog "we tried real hard" defense.
Woo Boy!

Nope, they're still banned.

Nope, they were never banned.

NA 12a and 13bs would get to 200k+ miles with just regular oil and spark plug changes. People still consider that "unreliable", apparently.

That mostly depends on the driver, also the Ro80 did this in the 70s with 70s oil.

>A rotary/electric hybrid would be the way to go since it can utilize the wankels high specific output at about 80-90% power output and can charge its batterys while getting the wankel to the desired temperature.
That's a really, really good point.

You're supposed to stick around 2000-3000rpm for a while to warm it up. Not too low that it takes forever to warm up, and not too high that it's not slick enough inside.
With a hybrid electric, the ECU could keep it up there to warm up while it's actually using electrical power to move how you actually want.

But wouldn't that be limited to a series and not parallel hybrid? Those are less fun.

Alternatively, you can use that electricity to heat the block and oil directly, eh? That'd be even better for reliability.

Non Reciprocating piston engines were not permitted to enter the following year
Rotaries were not outright banned. They just didn't fit into the new requirements :^)

Its like "niggers are banned from the bar"
No, I've just white listed everyone in town who isn't a black cunt

Read the class rules. Only piston engines are allowed for LMP.

They may be allowed in the same class as cars like the Corvette and Ford GT, it's unclear to me, but they definitely aren't allowed in LMP which are the classes that really matter.

nope, mazda had the option to recalculate their actual displacement to bring them inline with 4 cycle competitors but they declined. mazda ragequit lemans.

13B-MSP (aka Renesis) was notoriously fragile.
However that's mainly due to cutting costs and the problems were fixed in the later iterations.
