Super neat performance engine, doesn't make sense for commuter cars.

Rotary's are shit.

Inefficient combustion - Uses way to much fuel for power
Don't rev high - rotor does 1/3rd of the RPM indicated on tach
Heavy - 13b's with full turbos/intercoolers weigh more than a V8 LS
Can't deal with changes in conditions - slightly dodgey fuel and detonates, goodbye apex seals

>rotor does 1/3 rpm indicated on tach
No shit, it's a 3:1 ratio between the crank and the rotor.

so the tacho is actually a combustion event counter?
WTF! I hate rotary now

I'd only use rotary on a track unless I'm stuck using it in a DD before an inbound swap.

No, he doesn't know how rotaries work.

>crank
you just repeated what I said?

What i'm saying is rotaries aren't the high revving magical machines that people perceive them to be.

But the rotor combusts 3 times for every rotation? Does the tach say 24000 rpm when I hit redline in my FD? Nice meme useage anyhow.

I understand completely how the engine works. I've rebuilt a few - because they are unreliable.

But the crank itself revs high, and that's possible due to the wankel rotary design. You don't think rpm in a normal engine is measuring how fast each piston cycles, do you?

>communism has never won le mans

>crank

I don't know about you, but the tachometer in my piston cars reads ignition pulses, not the revolutions of the "crank". Do the mathematics for a rotary and tell me the RPM. Bear in mind the 3 combustion cycles per rotation, and the gearing from the rotor onto the eccentric shaft, and tell me how you end up :)

popularmechanics.com/cars/a8174/liquidpistons-hyper-efficient-engine-turning-the-rotary-inside-out-13817971/

Has there been any further news or information about this inside out rotary engine?

Let's do a different test. Hook a rotary and a normal engine to the same drivetrain. Put them both in the same gear. Now rev them to 5000 rpm. Which one will be spinning the wheels faster? Trick question, they'll be spinning the same speed.

At least I got a good kek out of your reply rather than thinking you were actually serious with the argument.

>13b's with full turbos/intercoolers weigh more than a V8 LS
in your dreams

the eshaft rotates 1080 degrees for the rotor to do 360 degrees
thats three times
the rotor does not go through a single combustion cycle in that time, it goes through three

you are a dead shit

I'm 100% serious.

>It's the only realistic way we can take care of everybody equally.

even if that were true (it's not) I don't care about that at all and neither should you.

Communism still exists today unlike rotary engines and national socialism

>In your dreams

It's a commonly held fact now. Yeah you hear people whinge about gearbox weight differences, but at the end of the day it doesn't weigh more or give negative handling characteristics.

You're just repeating what I already know and said in previous posts? Thanks man now I know how my RX7 in my garage works !!!

>Communism still exists today unlike rotary engines and national socialism

Are you referring to North Korea?

Rotary engines work, unlike the people who support communism.

I'd rather have unequal wealth than equal misery.

boat
anchor

National socialism is alive and well in my household, thank you very much

...

>National socialism still exist today

Lol

It sure is funny how it is always 'poor' people with envy of those who are more successful than them that ramble on about the desire for the Government to come along and make everyone 'equal'.

The rich stole the value created by the workers in the first place

>It's a commonly held fact now

in gm shitpost threads you fucking mong.

err, how about rx7club.com and fdrx7.com?

Maybe if you had a rotary, and went on other forums than this cesspit of bus riders you would know :) But what do I know, I only own a 13b powered late model FD and you've logged 1000 hours on gran turismo and watched a heap of engineering explained videos :(

I can smoke the fuck out of any rotary powered car in my 2000 EK hatch with a couple of simple mods.

>Inefficient combustion - Uses way to much fuel for power
Yeah okay
>Don't rev high - rotor does 1/3rd of the RPM indicated on tach
Literally a pro, are you stupid?
>Heavy
That's why they've been used in airplanes for forever, because of the poor power to weight ratio.

bread on hood
>inb4 nothing to prove

There will never be another rotary. Shit to seal. Too expensive to produce. RX8 will be the last.

Lucky you, you just won a free helicopter ride.

what is the point of the State if it isn't going to serve its constituents? Why the fuck should I give it my hard-earned money if it won't help make my life easier?

the FAQ for every generation on rx7club has engine weight specs. the engine weighs less than 300 pounds on the core block. do you even know what you're talking about?

Inherently unreliable because the rotor isn't being pushed down at a 90 degree angle like a piston.

Do you mind telling me what you're on? Because it must be some good shit.

They don't actually rev high, you have been lied to by a dodgy speedometer.

They are used in airplanes because of their small packaging, not weight. The turbochargers, intercoolers etc add a lot of weight. Funnily enough, rotaries used in planes are also geared post eccentric shaft to get the correct prop speed for a lot of aviation purposes :)

Better than a hood, how about an engine bay photo with my most favorite multi grain bread :)

Can you read? A fully dressed 13b weighs a lot. Not the keg of a motor minus everything that makes them good power. Do you even know what you're talking about?
Regardless, rotaries consume fuel at a rate far more than the "1.3L" lie you have been fed. Packaging wise, they are small. But adding on all the turbos the motor gets big and heavy, and consume fuel at an astronomical rate that can be compared to a huge V8, hence why rotaries are rubbish. At least they don't break down in your video games !!

>not weight

thats where you are wrong, aluminium rotor housing and midpltes and a single turbo actually reduces the weight a lot

>consume fuel
only you are constantly varying the RPM, at wot they are quite efficient

>It's a commonly held fact now
it really isnt

rx7club.com/3rd-generation-specific-1993-2002-16/engine-bay-weights-388361/page2/
its common knowledge a fully assembled 13brew weighs no more than 350lb, and thats with all the unnecessarily heavy factory equipment :^)

>You're just repeating what I already know and said in previous posts?
so then you should understand that the engine is spinning at the exact rpm indicated by the tach
fucking idiot

>I know how my RX7 in my garage works !!!
as do i

Everyone in this thread got BTFO.

>The turbochargers, intercoolers etc add a lot of weight
typically naturally aspirated rotaries are used in aircraft,

how much weight manifolds, ignition and fuel setup gonna add onto this?

So you're saying by running aftermarket engine components and turbo assembly it will be lighter? Wow! i've been doing it wrong all along! someone tell mazda !!! No matter what way you cut it, they are heavy motors from factory when fully dressed.

At WOT they are so horrendously inefficient you can go through a tank in no time. Dear god I hope you are kidding.

>v8 fags literally this mad

>Wow! i've been doing it wrong all along! someone tell mazda !!!
are you implying the factory equipment is better than aftermarket alternatives?

>they are heavy motors from factory when fully dressed
still 180lb lighter than an ls1

employment is a trade you mong

you don't like the terms, don't go to work

just starve and die. reduce global warming at the same time. it's a win win for the universe.

>b-but it's aftermarket so it d-doesn't count
sorry cuckold, we are arguing about the rotary engine in general, not mazda's production engine alone

>At WOT they are so horrendously inefficient you can go through a tank in no time. Dear god I hope you are kidding.
wrong

that LS doesn't have fluids, it was confimed in lstech

That thread is missing a huge amount of parts. If you didn't selectively search, you'd find that the weight is that close to an LS that its not even worth noting. That weight is also for the older FD not the late model one which have a few different components. The radiators, oil coolers etc for the rotary are huge and weigh a lot. The ASTs and all other peripheral life support components to keep the engines running compared to a piston engine is phenomenal, not many people realise that.

The eccentric shaft is rotating at 8000rpm, but the rotors aren't. You're delusional and lapping up the lie from mazda that your engine "loves to rev!", when the reality is that they don't rev like you think they are revving. They idle at super low RPM, hence why the bridgeport bounce sound is so pronounced. If you compression test your 13b with the plugs out, you can hear the individual cycles of each rotor as they pass the spark plug castings.

Thanks friend :)

>That thread is missing a huge amount of parts.
name them

>The eccentric shaft is rotating at 8000rpm, but the rotors aren't.
stop being stupid, that is like saying a piston engine doesnt rev high because the camshafts do not spin as fast as the crankshaft

>keeps saying it weighs as much as an ls
>says threads everywhere on rx7club stating so (even though all the threads on rx7club say no more than 350lb)
>cannot back up a single one of his claims
its near 200lb less than an ls12
deal with it

>radiators, oil coolers
i dont see any radiators being weighed up with an ls engine.. irrelevant

>The eccentric shaft is rotating at 8000rpm
there we go :^)

>You're delusional and lapping up the lie from mazda that your engine "loves to rev!",
so the rotary performs better at lower rpm than when its being strung out?

i dont get what youre saying
you are being contrarian just for the sake of being a faggot, and all your shit is retarded

COMMIES BTFO

meme engine, but cool concept

I literally named some in my post. The fact I have to name them definitively shows that you don't have a clue what you are talking about.

Camshafts? Next thing you will be quoting is the RPM of your turbo! I don't know how you can keep debating it. Its a fact they don't actually rev high. Eventually you will come around to understand.

Yes aftermarket components are rubbish. Speak to an engine builder and if its not a crazy mega dollars build, oem parts are the way to go. Look at the amount of threads debating different aftermarket apex seals that chew through housings or break on the slightest amount of detonation. One of the most crucial parts of the rotary and yet still aftermarket seals of all manufacturers have pages and pages of debate about how bad they are, yet the mazda seals keep ticking along just fine.

The fact is that no-one can actually justify how the rotary is better than the equivalent LS. Matt Farrah says it well in his comparison of the LS and Rotary FD on the Drive channel, which most people would have seen. They are fun engines, but incredibly flawed. It genuinely seems to be that the only people that come in to bat for the rotaries are people who don't own them. It's pretty much an untold truth by everyone in the rotary community that LS's are better motors everywhere by all metrics, but thats not the point of owning a rotary engine. I'll end here because my posts are falling on the deaf ears of busriders, civic and miata drivers.

>oil cooler
>radiator
these aren't weighed in LS or other engines meme pics

>The fact I have to name them definitively shows that you don't have a clue what you are talking about.
No, the fact that you fail to name them proves that you do no't know what you are talking about

>Next thing you will be quoting is the RPM of your turbo!
No, because I am not a fucking idiot like you and I know that RPM are measured at the crank

>Its a fact they don't actually rev high
wrong, measure the RPM at the crank like a non-autistic person

>Yes aftermarket components are rubbish.
lel, next you are going to tell me about how billet parts wih tensional strength 10 times higher than OEM are trash

also
>rubbish
fuck off limey

>Look at the amount of threads debating different aftermarket apex seals that chew through housings or break on the slightest amount of detonation.
seals that chew rotor housings are badly manufactured, uneven seals and bad srpings damage rotors, and this have nothing to do with being oem or not

>Matt Farrah
Matt Farah can suck my fucking cock dude

> that LS's are better motors everywhere by all metrics
only due to the extra displacement, a 3 and 4 rotor engines make much more hp/kg than LS engines

>I'll end here
ragequits because all his arguments are regugitating what he saw on Matt Farrah video lel

>Yes aftermarket components are rubbish. Speak to an engine builder and if its not a crazy mega dollars build, oem parts are the way to go
speak to an engine builder and the very first thing he will tell you is to upgrade the ast, radiator and oil coolers as well as cleaning up the vacuum mess.

i cant believe you own an fd and are willingly this ignorant. enjoy your dead engine.

>The fact is that no-one can actually justify how the LS is better than the rotary
FTFY

the fact 98% of people running heavily modified FDs for road racing and time attack use etc are still using a rotary engine should say enough
in fact a couple years ago a 13b fd and an ls3 fd were running in the same class at wtac, the ls3 had more power, it got spanked by several seconds =//

ITT: reasons why rotary engines don't exist
>they do

Posters are full of shit or I've slipped into timeline B.

Are you deadset retarded ? The AST in that image is replaced with an aluminum one. The radiator is a koyo N flo. Guess which of those parts weigh more. Stock or aftermarket ! PS vacuum lines have been replaced too, not that you would notice :)

>resorting to insults
>Your arguments don't count for x reason!!!!

>h-he called me an idiot mommy!

then next time measure RPM at the shaft you idiot

your argument is stupid because OP is talking about rotary engines as a whole, not mazda's 13b

>Are you deadset retarded
nah, im not you :^)

aftermarket>factory
the factory internals are fine, but everything surrounding the engine is subpar because mazda went full kike for production

311lb vs 498lb :^)

but they do, just not in cars
they are manufactured on a large scale for uavs and shit

>Stole

Yup

Please look up the meaning of stole.

Really? Which use rotaries?

Please do user

The army wants to buy small ones (~3 HP) as generators for exo suits

>Exo suits
>Existing
>A good idea
>Anything beyond a recruiting/budget inflating gimmick
Go ask /k/ about them.

The point of the state is to have a holding tank for the best and brightest sociopaths. Like daycare for the criminals that are smart or lucky enough to avoid prison. Serving the people usually a side effect. Our choice wheather we get served or not. We run the prison.

Rotary is great at steady state continuous running or in a less regulated world.
> Starting, stopping, cold start, lugging your fat ads to taco bell. That's where the problems start. >Sealing the side and tips of the rotors and lubricating them without blowing oil/charge out the exhaust.

Direct injection and a variable intake/exhaust port scheme could make the rotary viable in today's (((regulated))) market. But nobody got the money when we still havnt recovered from 2001 and 2008 depression and leaders want ww3. And japs get worse at innovation with every rotation of the earth.

I bet you have no idea how much planes and helicopters actually weigh

>one has transmission and clutch assembly still bolted to it and the drive accessories
>one has no transmission or clutches and no assemblies except a water pump
really activates my almonds

Rev up those helicopters.
