Has there ever been a worse engine layout than the meme triangle engine?
>incredibly shit fuel economy for the amount of power >burns a lot of oil by design >unreliable and has shitty quirks like being easy to flood >sounds like shit >no torque >apex seals are fucking stupid
Seems like the only upside is because they produce a decently high amount of power relative to the displacement, they are sometimes cheaper to insure because in some countries cars like the RX8 just appear as a 1.3 four seater. But other than that, they are utterly pointless.
>decently high amount of power relative to displacement
Nigger you can easily get an FD to 500-600 horsepower out of a fucking 1.3 liter THAT WEIGHS LESS THAN 250 LBS WITH A SINGLE TURBO CONVERSION
Fuck off with your "decent". The only shit thing about rotaries is the fuel economy, and even then that has a lot to do with how god damn rich they run from the factory (yes, obviously also because raw fuel getting shot out, but this plays a huge part too). Any idiot can rebuild a rotary, and every rotary since the S5 FC has a built in flood fix where you hold down the gas pedal and crank, just like any other car.

Yeah but at the end of the day who gives a shit? If I wanted 500-600bhp I could do it with half the headache and a million times the reliability using an LS motor.
James Jones
They're essentially outdated motorcycle engines, but with less torque. LS is way better.
Evan Harris
The LS weighs 500 lbs and will drink fuel at almost the same rate pushing 600 horses, and it also sounds like shit and moves that 500 lbs forward over the axle. Then you have to install a mounting kit and can't use your stock gauges, you need a new tranny, and at the end of the day you're stuck with a pretty car with an ugly engine with a shit exhaust note and boring power band.
"half the headache" see above. I would trust a rotary before I'd trust a chevy engine if I built it myself, it is incredibly simple and you can rebuild it yourself while watching TV.
Benjamin Bennett
but then youd have a shitty pushrod engine thats one of the worst sounding engines of all time
youre not even an enthusiast if you LS swap at this point your just a normie following memes

Because you're incompetent as a mechanic.

They are inherently a better engine for race applications, as they survive better at high rpm than piston engines. As street cars, not so much.

is it so hard to believe a race association (for le mans) controlled by the auto industry can bend rules or even out right drastically fix a race? especially when billions of dollars are on the line.
rotary engines are 100% marketing and 0% engineering billions of dollars at stake
this is the mazda scam
Juan Anderson
>unreliable and has shitty quirks like being easy to flood
They're not unreliable. They're reliable and will last as long as almost any other engine if you leave it NA. It's when you start boosting that you start having more issues.
Nolan Sanders
Any one who says "LS swap!" With out understanding how it affects suspension geometry, how the suspension is now compensating for several hundred more pounds and ruining it's driving dynamics, ride, and handling. Not to mention heat and it's lack of dissipation escaping in to the cockpit.
LS isn't inherently wrong, but it Fucks up the entire point of an FD.

Can't you retards find other cars to ruin? If you're not driving an RX7 for the handling and balance, get the fuck out.

Because a rotary was in LeMans long before that my nigga. >The Sigma MC74 powered by a Mazda 12A engine was the first engine and only team from outside Western Europe or the United States to finish the entire 24 hours of the 24 Hours of Le Mans race, in 1974.

More like 100% engineering. He's probably just seen that old rotary ad from the 70s that gets posted as a joke. I think it's fucking insane that Mazda could make the most underdeveloped engine work, and make 2 legendary cars that used it, one of those winning a race and being banned immediately after the win.
Think about that for a second. Every other cars on the market use piston engines. 0.001% are rotaries and they hold up amazingly well, hell, the only times they fail are when people like OP get their hands on them and fuck 'em up! What's not to love about a story like that?

can you find any reliable sources which actually show the amount of energy is being output at the crank?
do you understand that all the engine dynamics being showcased on dyno tests and other mediums is pure unscientific bullshit? no?
do you know what marketing fluff is?
you dont understand what kind of joke you rotary-autists are to those who actually understand what is going on
Gabriel Kelly
>I have zero physics knowledge but I'm going to give you my opinions on why I think the rotary engine sucks -OP
Hudson Scott
Yeah, same.
The only reason that Mazda didn't win before was due to the fuel limits. The 26B was detuned to what, 6-700 horsepower? It could be set to 900, and that's without a turbo. 2.6 motherfucking liters. And dat fucking sound.
By the way, not sure if you know, but the engine was by far the best condition ever seen after winning LeMans. It could have raced another 24 hours or more without having any repairs done. That's amazing.
Christian Turner
I'm going to ignore this post because you are clearly angry that people don't want your shitty generic V8 murrican strong engine. Are you a cuckold or something? Don't you want anything unique? What's the fucking point of putting the same god damn engine in every single car? Why not just buy a fucking corvette in the first place if you're not going to turn?

Seriously what is this post trying to say? What the fuck? Have you ever driven a rotary? They're fast. What are these numbers and how are we being fooled/scammed?

Blake Parker
>50 KG lighter lmfao, well I can tell you're DEFINITELY not a senior level engineer of anything
The 13B weighs 150 lbs without a turbo, and you can shave 40 lbs off if you have aluminum side housings. It's so compact it allows for a front mid-engine setup. The only thing that isn't in accordance with its 1.3 liter displacement is its fuel consumption, that's it, and that can be fixed with proper fuel mapping and ignition. Pushing 600+ horsepower, there won't be much difference in fuel consumption as you'd think, and then you have the benefit of a high revving and fun engine that gives you perfect weight distribution.

Hudson Cox
alright retards, time to learn some basic lessons in physics
piston engines need more weight because this is how you house the detonation and energy output. if you make a piston engine lighter, it will literally explode from all that power
rotary engines solve this issue by producing less power. there is no miraculous engine design which cheats physics and houses similar or greater power in lighter package. YOU WILL LITERALLY HAVE TO BE CHEATING THE PROPERTIES OF THE METAL AT THIS POINT. and rotaries dont use any space age metal.
the fact is, there is no actual scientific studies done on total energy output at the crank. the industry purposely throws out fluff to confuse idiots with meaningless variables. and some idiot on youtube runs a dyno test, which doesn't mean shit, and you fags will literally eat this shit up
rotaries are literally the worst engine designs in history.

Pretty much any other modern performance engine would be a better platform for 600hp. The only way to make a rotary look good is by comparing it to modern 1.3s which is just dumb.
Christian Murphy

Here's what it does right, for you retards out there >puts out ridiculous power relative to displacement >sits low and behind the front axle, meaning 1. great weight distribution and 2. great balance being in the front with the diff in the rear >very lightweight >fun to drive, LOVES to be abused, it literally needs redlining regularly >easy as fuck to rebuild, and said rebuild will last a minimum of 100k KM, can go far longer than that without a turbo; a rebuild will cost you 1000 bucks in parts and you can do it while watching TV on a weekend, rather than shelling out thousands for a shop to rebuild your V8/spend all week measuring tolerances and clearances and not being able to pull the engine out by hand (fun) >sounds wild and revs so damn freely >is the sign of unique and clever engineering, unlike a step backwards like pushrods
what it does wrong >burns oil (less than lots of cars, though) >consumes a decent amount of fuel (I have NO idea why you care about this if you're american, your fuel is almost free compared to the rest of the world)--again, this can be aided, though >doesn't make lots of torque, but then again, we aren't asking for trucks to use these engines, and revvy engines are fun and great for long periods of hooning

They won leman once and lost all the other races the car was entered in.
Nathan Lopez
>>never mind that the car is overweight overall, just look at the engine in isolation Well that is the thread topic. Maybe you should try lurking more considering you don't seem to know how Veeky Forums works.
You sound salty
Robert Fisher
no torque meaning, any amount of weight will seriously cripple performance. for example, the average weight of a small car is enough to throw the rotary engine far out of its true efficiency range
to compensate, to achieve similar performance to a piston engine, more fuel is spent. in other words, more energy goes in and less goes out.
its amazing how so many people cannot grasp this simple science. literally millions of people, many of them who have positions as real engineers. very pathetic.
but the fact is, no real test of total energy output at the crank has ever been done or made public
Like that's not a huge accomplishment? The only Japanese manufacturer to win. Like I said, the fuel limits had a lot to do with their losses.
Anthony Brooks
You know full well that means nothing to shitposters
Easton Lopez
Doesn't that just mean it's a bad engine if it can't compete in an endurance race. Like what's even the point in using a Rotary if there's a fuel limit
Aaron Clark
>6 times the apex seals >2 gallons per mile
Angel Young
230hp (210 in reality) from an massively maintanence intensive engine incapable of averaging over 18mpg is pretty fucking bad.
Leo Ward
/thread
Michael Gomez
the swept area and rpms are irrelevant to bottom line performance like power, fuel consumption, and efficiency. In those cases even big dumb v8s beat out rotaries. That's not how technology is supposed to work, the wankel is a nazi abomination
Bentley Gomez
so what you are saying is that you want an engine that doesn't burn fuel to produce power?
Chase Mitchell
But its engine was in the best condition out of all of them after said race. That just proves its pedigree as a great sporty engine.
Dominic Torres
I actually agree with this because it's the truth. Here is a very big (you).
I would also like to add how rotary engines sound like pure shit. They make this buzzing noise, it totally sounds like chinese metal ass. And there is a real host of idiots out in this world who have convinced themselves this actually sounds good.
The rotary world is truly pathetic. It is packed with multiple levels of bullshit on every angle.
Brody Hughes

Michael Price
Sure buddy. You 'win', now get lost
Gabriel Robinson
They SAID that "it could easily do another 24 hours". Which is complete speculation and FAR from factual. That doesn't prove anything you fedora wearing jabroni. It's a sporty engine alright. It's loud and smelly and small and unreliable. Those are it's factors. That is not the definition of sporty. POWER is sporty. Yes, the rotary does have more power per "swept area" and can achieve higher "revolutions" per minute, but when you realize that you have half the torque of a v6 and your 1.3 liter gets 15 mpg you kind of just want to kill yourself for buying an fc for your first car.
Samuel Kelly
if the wankel was a mammal it would be a nasty little rat that gets tired and eaten by a common house cat
Matthew Green
You seem to know a "lot" about engines. Please explain how a rotary is less reliable, then, despite being much simpler. No, rebuild intervals don't count, because the cost is ridiculously less than a piston rebuild, and is infinitely easier
>POWER is sporty oh shit, you scared me with those caps, I'm not going to respond to the rest of your post. Because of the caps, and not because it was poorly written and wrong, I swear.
Ayden Thomas
have you never driven a rotary powered car? Even a NA FC pulls nicely with a good flowing exhaust, those high RPMs are where the power is
Jayden Allen
>qoutating your own subjective opinion It's unreliable because it breaks. Oh but it's fine it's only 300 dollars for a set of apex seals and you already have the special tools because it's the third time you've done it for this car.
>cost is ridiculously less
>infinitely easier
Do not criticize the way I write, because you have zero intention to write what you literally think. You are using this silly hyperboles and being defensive because you KNOW the rotary has problems. I'm using caps to emphasize because Veeky Forums doesn't have italics, dick.
Anthony Ross
what does a NA FC make? 160hp?
Leo Morgan
160, yeah. If that number really doesn't matter, I'll be damned, it's pretty pathetic and the one I've driven pulls pretty nicely
Cameron Jenkins
why not just put a motorbike engine into a full sized car
same principle as a rotary engine car, same snoflek status and possibly more reliability
Owen Morales
one upside is simplicity and SUPER easy to tune and get power out of
they also breathe incredibly well so larger ports and freer-breathing exhaust can get you pretty good gains unless it's a renesis (which is shit anyway)
Josiah Stewart
Dude don't get so mad, we're only arguing. Fuck, it's like you're having a temper tantrum because the 13B suits the FD better than a big V8.
Apex seals don't break -THAT- fast. In fact, for a lot of people it's the coolant seals that go first. And it's still a fuck of a lot better than blowing a rod. Basically, if you boost a 13B and blow something, it'll always be cheaper than blowing a piston engine (warping the head, shit breaking and destroying the engine internally, all of which are fatal). If the seals go, it's not fatal.
Yeah, I realize the rotary has problems. If every engine was a rotary and one in every 100,000 was a piston, I bet that would have even more. The rotary was tossed away during an oil crisis and then again because of emissions. For such a ridiculously uncommon engine to put out the numbers and driving experience it does, while being ridiculously mechanically simple, I think that's amazing.
Jaxon Jenkins
>FD RX-7 made 200HP/L+
Blake Morales
>uses twice the fuel for the same power >"bu-but it's a 1.3 liter bro"
Luis Ward
Motorbike engines aren't designed to cope with that much load on them all the time. For example DAF used to sell a 7.5t truck here with a 12v cummins 5.9 turbo that made 130hp, or 150hp in the high power version. They could have just have easily used a BMW 2.5l diesel to get that power instead, but the thermal and physical load on the internals would mean it wouldn't last long. Despite all the gearing memes you hear on Veeky Forums there's more things to consider when you're dealing with significant changes in weight loading.
Nathan White
