Why do poors do this?
they're copying mitsubishi evos which are super popular in the 3rd worldthose are vortex generators supposedly to improve laminar flow over the rear wing.if there is no big fuckoff rear wing they're rice
>>29028455Elementary, my dear
cheap mod whose skill ceiling is 'can you adhere something to your roof?'
They delay flow separation over the rear window.Not enough to quantitatively ever matter or offset looking like a ricer.Although, I thought they were a unique aesthetic touch to the evo.
Why do moneyfags always seethe when they see a poor person having fun?
drag reduction
>>29028560>believing thislmao
>>29028563you're right, they probably don't do anything
>>29028564So you want to create lift in you are car?Bernoulli’s Law of Principles
>>29028569Flappy flappy air is badSmooth air is goodNothing to do with lift
>>29028464>>29028455its on a wrx, its actually a dealer accessory on 2015-21 wrxs and stis
>>29028569the vortex generators aren't producing liftthat would be the wing, believe it or notmore flow separation = bigger wake = more dragyou want the air to stay attached as long as possible and leave the car as cleanly as possible
>>29028573>nothing to do with liftlmao get a load of this retard
>>29028569>>29028575in addition, having detached flow over the rear of the car actually increases lift, because it creates a low pressure zone, pulling the car up off the roadkeeping the flow attached will eliminate that low pressure zone and reduce the amount of lift, even without a rear wing
>>29028573>>29028575Ok explain the offcenter plate when they already have holes drilled in the center, the hilarious pikachu-tail like wings, the rep wheels without lowering, and the rice ahh rain guards
>>29028582are these things in the room with us right now, anon?
>>29028580this was already said in the second and fifth post redditor.again, they are reducing lift not creating it. spoilers SPOIL to reduce lift or shape flow, they do not generate lift.we get it, you're a ricer with vortex generators, it's time to stop posting.
>>29028590>they are reducing liftyes, vortex generators can reduce lift and drag by maintaining attached flow over the rear of the vehicleall this is contingent on your car actually having detached flow to begin with, however
>>29028582Consider that you’ve spent weeks, maybe months of your life obsessing about how teenagers mod their cars.
>>29028582>and the rice ahh rain guardsalso I don't want to let this sliderain guards are based, being able to crack the window on the highway in the rain without getting soaked and blowing out my ears from wind noise kicks assI wish my current car had them
>>29028590I always assumed anons that shriek ricer at shit were retarded but thanks for actually quantifying that for me
>>29028598Just avinalaffm8>>29028601I only see em on riced out pikachu bullshits
>>29028598its the bmw schizo, he's been at it for years
>>29028614That’s why I said it. He’s spent an inordinate amount of his life doing this shit. He doesn’t even want to talk cars, he just calls anything that isn’t a BMW rice while promoting BMW ricing and saying that every car needs to be slammed. If a BMW came out today with vortex generators, he’d say anyone who didn’t like them was poor and too dumb to understand aerodynamics. He wants people to think he’s successful and rich, while he spends every work day jerking himself off on 4chan.
>>29028619>nooo Alfa Romeos, Lancias, Ferraris, Lamborghinis, Studebakers, REAL Porsches, and Corvettes are ALL BMWs!!!Kek new BMWs are gay as fuckI’ve literally never called anybody poor LOLMODIFYING a car to be Better isn’t “ricing”Whenever I talk about cars some ricelet TASTELET will always say some hilariously inane shit like “now try driving this on the street. you'll be oh so disappointed when your precious Porsche scrapes on every small bump. not like youre old enough to understand"
>>29028666Delusional.Not even joking, you constantly have delusions of grandeur followed by delusions of persecution. Schizophrenia is when you believe these delusions so strongly that you act on them, it appears you’re crossing that boundary.
>>29028619you shouldn't need us to tell you you're screaming into the void, you might as well be getting mad a bot. all you have to do is filter one or more of these words:>pikachu>ricer/ricelet>tastelet>wrenchlet>bmaoand you'll only see it posting when it deviates from its normal formatting
>>29028680I don’t filter anyone. It’s interesting to watch. It’s be better if he hadn’t driven off most of the regulars that actually know and talk about cars.
>>29028679LOL what the fuck are you on aboutHow are any of those cars BMWs?How is MODIFYING a car to be Better riciing it?When have I called anyone poor?>>29028680I never say “wrenchlet” since it just means tinywrenchI prefer to call them nocarsAnd if those regulars know so much about cars, why are they such tastelets?
>>29028569Bernoulli is a bullshit meme that has almost nothing to do with aerodynamic lift.
>>29028455they’re standard on Evo’s?
>>29028854Yeah, on some trims of the IX. Maybe the VIII too, don't recall.
>>29028726Spaced out like a faggot
>>29028679lol nailed it.
>>29028557Because poors pretend that their fake fun (le heckin reliabler slow car fast) is better than real fun (buying an actual fast sports car)
>>29028455>when you see them and you can tell at least one is mounted crooked

>>29028953thanks for the extra words, forgot a couple
>>29028982Kek I’m not hispanic at allWhy are you mad at Me for ricelets mostly riicing their cars in the same hilarious way as each other?Mostly>>29029052What are you on about beancounterboy
>>29029002>fun>installing some do-nothing modification because some mitsubishi had it onceif I were poor I'd just spend the money on tint
what even is going on in this thread
>>29028455>>29028560>>29028575>>29028595If this shit works, why don't we see it as a standard feature on all hybrids and EVs?
>ricer hate threadProud of you boys keep it up, pretty soon based niggers will start posting
>>29029765>If this shit works, why don't we see it as a standard feature on all hybrids and EVs? see >>29029765>all this is contingent on your car actually having detached flow to begin with, howeverthe egginess does most of the work, but also these function as vortex generators to keep the flow attached along the side of the car
>>29028455Is that the BRZ? That's a factory option.
>>29029086>The only things that are fun are what I deem to beOkay, I guess.
>>29030203not brz ventst. brzchad
>>29030212useless aero mod (assuming you don't have a giant fucking wing) or useful tint
>>29028455Mainly in order to annoy (You).
>>29030249its literally a factory option on 2015-21 wrxs and stis SUBE751SVA000bmw shitter just has a obsession with subarus
>>29032071
>>29028560>high pressure under wing
>>29033439it's an upside down airfoil
>>29033439>>29033441nvm, I see what you meanI guess it's probably due to the angle of attack?
>>29033451It's because it's a retarded bullshit marketing image for a totally useless product not an actual CFD analysis.
>>29033457the aoa thing checks out thoughnegative aoa causes a high pressure zone at the front of the wingits more a reflection of the quality of the model than of the cfd
>>29028574>>29028464these have been a thing since AT LEAST blobeye era. possibly even before.they used to be dealer options.they don't do anything perceptible.>t. old
>>29033628>they don't do anything perceptibleYou could probably do some tuft tests to see for sure if they have any effect. In theory you would see cleaner flow around the lower portion of the rear window.
>>29028573>smooth air good>flappy air bad>installs flappy-air-generators on his vehiclenani?
>>29033641vortices != turbulence
>>29033628they don't do anything on that particular subaru because, as you very clearly demonstrated, they are just copying mitsubishi, specifically the Evo 8, without copying the technical reason (big, tall wing, fast car, wins rallys without being beat half to shit by a drunken scot).without a big wing the vortex generators are indeed useless because the deck spoiler is too low to even be in the airflow path, if that subaru had a wrx wing they would work properly.typical dumb fucking subaru lesbian has no fucking clue what she's talking about
>>29033648>without a big wing the vortex generators are indeed useless because the deck spoiler is too low to even be in the airflow paththe vortex generators keep the flow attached down the rear window and over the trunk lidin theoryyou would have to do real world tests to be sure
>>29033651except for the pocket of air that gets trapped in the notch between the window and decklid that causes flow separation and turbulencewhich is why on evo wrc the big wing ended up precisely right there
>>29028936>buying fast>not making fastyou're just as much as a carlet as they are
>>29033661>except for the pocket of air that gets trapped in the notch between the window and decklid that causes flow separation and turbulenceThat's what the vortex generators would be trying to mitigate. The car in your pic doesn't have any.
>>29033666no fuckin shit dumbassthe evo wrc has no vortex generators specifically because the wing was moved into the pocket of air in the notchback that the vortex generators were initially there to mitigate.jesus christ subutrannies are dumb as rocks
>>29033674I don't even drive a subaru. I'm just autistic and like geeking out over the efficacy of various automotive aerodynamic features. I see what you're getting at now though.
>>29033701It would seem to me that the present solution is sloping the rear glass more to keep the flow attached (or abandoning sedans altogether for the objectively superior hatchback body style) instead of trying to put band-aids on what is ultimately a flawed design.
>>29033701yes, notice how in the picture you posted the lower tier of the wing is actually sealed against the glass with a gasket? the wing IS the vortex generator.
>>29033704the evo wrc hasn't competed in almost 20 years and only looks the way it does because it was getting its lunch eaten by hatchbacks for that exact reason
>>29033707Isn't that just acting as a regular spoiler and positioned so that it "catches" the flow before it detaches? I would imagine there are some strange things happening over the part of the trunk that sticks out past it.
>>29033709>Isn't that just acting as a regular spoilerthe top part isthe bottom part is trying to aerodynamically mitigate the trunk https://airshaper.com/blog/transforming-rally-car-aerodynamics
>>29033712Good read, thanks. It seems like the only actual reason they sealed the lower wing to the window was due to FIA regs?
>>29033716that might have been the open reason because they didn't want to claim the car was aerodynamically inadequate compared to its competition because it very much was. if that gasket wasn't there the wing would produce less downforce because half its purpose is to keep air out of the notch and the other half is to balance the center of lift, allowing air under the lower spoiler would definitely reduce its effectiveness as an airfoil, increase drag and reduce downforce.
>>29033637they work - as in, they generate vortices.their effect is just extremely small. in most cars the effect is either negligible or "negative" (still not enough to matter)see >>29033648 for the cases where it actually makes some (but not *that* much of a) difference
>>29028455These are for preventing ice sheet buildup you retards
