SUV Corvette coming up.
>still sold with pushrod engines>zero other cars sold with pushrod enginesembarrassing
>>28897594>New 6.7L V8Based. No replacement for displacement. Displacementcels and cylinderlets BTFO.
>>28897601>Mid-engine SUVI want to see what that would look like
>>28897606must make rotards mad knowing GM still sells cars with pushrods engines while the RX9 is just a fantasy that'll never happen.
>>28897609>new>pushrodsall this time and they couldn't figure out twin cams>>28897611or it could just be a wagon which would make much more sense
>>28897606LS6 makes the most torque in a N/A V8 and the entire powerband is torquey. Pushrods=PushGODS
>>28897617at the expense of fuel economy + because all other manufacturers switched to 4L TT v8sliterally only chebby is stuck in the technological dark ages
>>28897594>>28897609Lel 6 7
>>28897619>4L TT v8sWorking on those engines is hell
>>28897611>Mid-engine SUVNah, they wouldn't bother. It would just be like the Mustang Mach-E or something.Fuck, just the thought of some clueless normie asshat proudly telling me that he drives a Corvette and it's pic rel pisses me off.
>>28897623audi hasn't used a 4.2L engine in a whileyou aren't showing the chain for whatever their newish 4L engine design is that gets used on everything from Audi to Porschethey are ripping off their customers and you are fine with it
>>28897625>but it rocks!1You can tell a jeet made that
>>28897594Grand Sport X replaced the E-Ray
i literally cannot stop winning it's unreal
>>28897645Yeah yeah, fuck off with your tired shit flinging. People are talking.
>>28897645The Vette looks pretty riced out so Im not seeing the fancy loafers connection?
>>28897623
>>28897594That is odd, how many engine configs is that?
>>28897708Those 4.2s were never offerered with a manual so you can't even really experience the engine for what it is
>>28897721this a joke?
>>28897594>A Corvette for everyone.Not us manual chads though
>>28897626>This nigga thinks low quality 25,000 mile euro turbo bombs are better than a N/A pushrod V8.Anon plz....
>>28897619>muh economical engine>in a performance carlollmao
>>28897748a 4 liter twin turbo twin cam v8 is gonna get WAY better fuel economy than a 6.7L pushrod engine
>>28897750mine get about the same, 12-15mpg
>Pushrods are heckin bad! Erm, because I said so! Nobody else is doing them so it must be ze bad! I'm a bandwagoneer populous and can't make informed decisions myself!!!!! Imagine crying about a company not fixing something that isn't broke. It's like you enjoy getting raped by unproven systems and hate objectively proven engineering.
>>28897750again, who cares about how economical your engine is in a performance car
>>28897762I mean, all the other manufacturers switched to tt 4L v8s - uniformly, there's probably a reason for thatI get 28 mph in my compact crossover :) on the highway >>28897754pushrods are bad because they prevent horsepower and torque and I think lower the overall compression ratio because you have to fit the pushrod plumbing next to the block instead of up on the heads (not an expert tho), but I mean they have been phased out and are associated with older engines for a reasonits weird, its like you shilling carburation instead of fuel injectionyou are glazing chevy for being cheap and lazy the corvette should have a twin cam 4l turbo STANDARD with a larger engine the upgradecan you explain why the zr1 has been twin cam since 1990?
>>28897765because 0.5L per cylinder is a good compromise in terms of power/weight/efficiencyit also lets you design your engines modularly to save on manufacturing coststhats it, thats the whole reason
>>28897765bro you have no idea what you're talking about. you don't even like cars why tf are you here arguing about this
>>28897770I appreciate tech and interior design. I just don't care about racing or numbers.
>>28897772then shut the fuck up about pushrod V8s and go start a thread about curved LCDs or some shit you fucking moron
>>28897765>Schzio randomly brings up Carbs when discussing PushrodsAnd you expect me to take you seriously?>I'm no expert but I'm going to spew delusional tiktok tier nonsense as a way to appear smart>Those pushrods? Heh, yeah those lose torque and horsepower Meanwhile in the real world: That pushrod vette has the most torque of ANY N/A V8 Pushrods were phased out because of strict emissions regulations. Not due to hitting a performance ceiling. There's a variety of ways to build an engine, the key advantage to a pushrod setup is how simple it is as a whole (which is ultimately pro-consumer thanks to its simplicity)If you think giving credit where credit is due is "glazing" then sorry chuddy but you're just a shitty human being kek.>pic rel gapped the world>>28897770FACTS dudes a fucking poser in the wrong part of town.>>28897772You do not belong here, stick to art school you dweeb ass wrenchlet. Know your place and stay in your lane corny ass cocksucker.
>>28897775they are FLEECING their customersmustang switched to twin cam even - they were a long time holdoutchevy doesn't do this for ANY reason but to save money to make more profitpushrods are less efficient and make less power liter-for-liter than twin cam engines
>>28897782Oh brother this guy stinks, faggot double downed instead of eating a slice of humble pie. Pathetic.
>>28897782no clue why you're so fixated on proving to us how much of a fucking idiot you are tonight.
>>28897781its not random its an example of an outdated technology that most manufacturers discontinued but some kept longer than others just to save money and make more profit - like pushrods in this case>>28897785it is absurd to come up with a new engine and not fix the design so its twin camsjaps switched in the 80s99% of engines in passenger cars are DOHC
>>28897791>More baseless delusions >"fix">"profit"You really do come from tiktok wow. Newsflash retard, all businesses (ALL) primary objective is to generate revenue. The only absurd thing here is how stupid you are. I pity you, your life is gonna be so hard kek
>>28897791autistic retard or llm on the fritz, call it
>>28897793and yet somehow ALL their competitors switched to twin cam designs
>>28897797>This deleted plebbit comment will surely be the silver bullet to prove my delusions>>28897795Imma say the later rather than the former. It's not autism it's pure arrogance.
>>28897797
>>28897802>but if you just want to waste as much fuel as possible pushrods are greatok start herewhy does the zr1 use a twin cam engine?
>>28897806epa regulations. anything else mr compact crossover?
>>28897772>I just don't care about racing or numbers>ahhh muh race car engines and epa mpg figures
>>28897806What a slippery little rat you are. Moving the goal post when proven wrong? How shameless.
>>28897808What are your thoughts on macpherson vs bones?Saying "pushrod is good enough" is taking the maccas' side.
>>28897813the most powerful engines driving the fastest cars in the world use pushrodsthis is an unequivocal fact
>>28897813>pushrods are bad because they prevent horsepower and torque and I think lower the overall compression ratio>pushrods are less efficient and make less power liter-for-liter than twin cam engineswhen proven wrong:>duuude the gas mileage though!youre a complete fucking idiot. i'm done talking to you.
>>28897817>they prevent horsepower and torqueyou are not gonna fit a giant drag racing engine in a production carthis is about horsepower PER LITER, which pushrods fail at compared to twin cam/twin turbo designsexplain why ALL other manufacturers include chevy's own ZR1 use twin cams onlycorvettes are sold to boomers most of whom will never use half the power they make, not that you even could outside of a track without reckless driving
>>28897817That was my 1st post in this thread.Idc about gas mileage. DOHC (esp with cam phasers) allows for higher redline and different lift profiles at the top and bottom end of the rev range so the whole range isn't a compromise.It allows for higher redlines and gearing advantages. It was designed to get around displacement tax, but it does work and is better 99% of the time.Some nitromethane engine that costs 5 figures and lasts literally seconds isn't saying much. Similar "argument" as the maccas guys you rage at who post rally winners with maccas.
>>28897594Still makes more sense than Porsche's naming scheme. "It's a 911 997.2 turbo S Carrera GT3 RS Singer Weissach RWB"
>>28897823Top fuel dragster long blocks are smaller than DOHC long blocks
>>28897843how many liters of displacement? that aint gonna fit in a fwd normal car
>>28897843No one is putting a top-fuel engine in their street car, don't be silly.OHC / DOHC was designed specifically so you could accelerate the same with a smaller engine as a bigger engine can while also cheating emissions / fuel regs. Adding it to a gigantic engine will still provide benefit. Whether that's cost-effective to a race team is another thing.
>>28897846we're not fucking talking about fwd normal cars though are we
>>28897846You got a dick in your ass or something?
>>28897849You're not putting a top-fuel nitro engine in a vette or bmw either, kid.And yes, we are talking about normal cars, do you want your vette to need an engine replacement every 5 seconds. Not joking, those engines last 5 seconds. You were being disingenuous by bringing up the nitro engine in the first place.
>>28897853you said pushrod engines are>good enoughwhen they represent the pinnacle of combustion engine designDOHC engines are the good enough compromise
>>28897823There are ~11 liter big block Hemi V8's making well over 5500hp on a hub dyno that are capable of holding together for an entire season of racing. Where are the DOHC engines with numbers like that?
>>28897861DOHC is more-complicated. It's cheaper and easier for a racing team to run and maintain a gigantic pushrod engine. I like that sort of thing too, but it doesn't mean it's "better," nobody makes 11L DOHCs to compare it to (likely for the reasons I stated above).
>>28897861how much gas does that use? spaceships go really fast anon
>>28897863Cost is irrelevant in the semi-pro to pro racing world. They're going to use whatever's faster. If DOHC V8's were truly better people would be using them more. Sure the Coyote is impressive but it won't be replacing big bocks anytime soon. >>28897866>how much gas does that use?The guys doing drag week get anywhere from 10-20mpg highway. inb4 that's bad. It's a street legal 6 second car...
>>28897875Sounds like a lot of cope.DOHC literally gives smaller engines an advantage. Adding it to a huge engine would provide similar benefit.Also, race engines are always in their powerband, they can be lift/advance timed for the peak and only the peak. A street engine is usually not above 5k rpm and DOHC allows such engines to be driveable while also accelerating as well as larger engines. Apples and oranges.
>>28897866who cares about fuel economy in a high performance application?
>>28897886id rather not boil to death on a flaming hot earthsports cars are antisocial and all the idiots who buy them should be beheaded
>>28897879Mercury Marine makes a 7L DOHC LS for street vehicles. The power numbers are not that impressive for all the added complexity. It's the size of a big block pushrod V8 that can make the same power on pump gas with a perfectly drivable powerband.
>>28897887
>>28897887then why are you here on the automotive enthusiast board posting in a thread about sports cars?
>>28897888Okay, but giving examples from various applications doesn't prove anything.I can show you cars on macphersons that run faster lap times than dbl-wishbones ones, but that doesn't mean they're better. There are a lot of variables to cars.
>>28897890anon its a car board, you don't have to be an "enthusiast" I find cars an interesting reflection of the values of society
>>28897908do you post on /k/ advocating for gun buybacks?this is a hobbyist forum
>>28897914the government shouldn't be allowed to own or use guns
>>28897908Cruise ships each burn 80,000-100,000 gallons of crude a day and serve no purpose.Airplanes don't have emissions controls.Fossil fuels are the main source of electricity that powers EVERYTHING around you, and no one bats an eye.40-70% obesity and farming is a huge source of emissions but no, ignore that, it's body positivity. Think of all those refrigerated trucks and store refrigerators just there to sell garbage food which only 1/3rd of will be eaten, and all the fertilizers, there's just so much off that one thing you could focus on.But cars?! NO oh no no, they are the source of pollution even though they have crazy levels of emissions controls.Get bent.
>>28897894It's pretty cut and dry when it comes to pushrods being superior. Until a DOHC runs a 3 second 1/4 or holds a land speed record that will continue to be.
>>28897917ban cruise shipsban all non-essential air travel regulate heavy trucks more strictly>Fossil fuels are the main source of electricity that powers EVERYTHING around you, and no one bats an eye.more nuclear plants please
>>28897918>Engines specifically made to run at peak get records>DOHC allows for street cars to be reasonable at low rpm and faster than similar-displacement pushrods at high rpm.Apples and oranges.
>>28897920I agree with all those things. I love sports cars, I've been racing for decades, but I don't think my impact on pollution has been large. Overall I think I'm in the bottom-20% of Americans on overall pollution. It'd be nice if we had recycling here, but you can't even pay for it.
>>28897929I never suggested sports cars are a big part of the pollution puzzle, but they are undoubtedly far less efficient than other cars and are largely bought by boomers to show off and be wasteful and a lot of people buy them to drive in unsafe ways that threaten others. Having had people tailgating me often enough, I just don't like fast cars.
>>28897932Lots of things cause pollution just for "fun." Sammy down the street with his Funko Pop? That was synthesized out of crude, extruded with great energy, and shipped across the entire world. For what? There's got to be a reasonable balance, you can't just say "I don't like X" and expect it to be banned.>Having had people tailgating me often enough, I just don't like fast cars.Have you considered staying out of the passing lane or not being a little whiny bitch? Everyone gets tailgated sometimes, and it's usually not by sports cars. If you're tailgated often, it's because of something you do.
>>28897935i mostly get tailed in the right lane or on one lane roads with no designated pullout lanesI ALWAYS yield where safely possible
>>28897841Porsche has the worst naming scheme
>>28897617Unless it's a truck, torque is irrelevant. Horsepower is what matters and LT6 is the most powerful production N/A V8 and it's DOHC.
>>28897949Oh yeah, well I don't. And when I do get tailgated it's NEVER a sportscar.
>>28898468Retard alert. Torque is the smart man's horsepower. If you know you know, and if you don't well sucks to be you.
>>28897765>you are glazing chevy for being cheap and lazyGet the C8 Z06 or ZR1 then, they use DOHC designs.>But it's more expensi-Exactly. There you go.>prevent horsepower and torqueKek. Top Fuel dragsters that make upwards of 10,000 lb-ft of torque use pushrod hemi V8 engines. Show me a naturally aspirated production V8 that makes more torque than the LS6.>lower the overall compression ratioLS6 has a compression ratio of 13.0:1>twin cam 4l turbo STANDARDThat's gay as fuck and retarded. Pushrods are advantageous because they make more power in a smaller size form and the simplicity drives cost down. That's the reason why they can fit so much power into such a small size chassis as the Corvette or Viper which also uses a pushrod design. The whole "LS swap it" meme started partly because you can fit an LS motor into anything, even a Miata, thanks to the pushrod design. Good luck getting a Coyote in there.https://www.youtube.com/watch?v=j6D1dZ1yAPEThose Viper pushrod engines can be modded for insane power too.https://www.youtube.com/watch?v=JvOR0QXFQUwThere is no replacement for displacement and pushrod engines are optimal for chasing massive amounts of displacement. Plus they sound better with a nice deep traditional sound versus the raspy ear rape of DOHC V8s. Flat plane V8s kind of fix that issue though.
>>28897795>>28897890It's a zoomer using a LLM to argue
>>28898483torque is for tractors retard
>>28898520The Viper engine is what the 2JZ wishes it was.
>>28897750Ah yes fuel economy, a top consideration in an expensive performance car. Fucktard euro.Pushrods push gods. Volumetric efficiency, displacement regulated racing rules, and other such numbers aren't relevant on the street. Area under the curve in gear is. Stay mad lol.
oh it's pushrods retard againstill hasn't accepted that the fastest car in the world uses dohc
>>28898520>Good luck getting a Coyote in thereYou can with some custom hood work.
>>28898915>custom hood workif that's what you want to call a hood delete lol
>>28898915Is that air intake unusually massive or is it just me?
>>28898925It's pretty large.https://youtu.be/wByA8Al2iCg?t=600Goto 10 min if the timestamp link doesn't work.
>>28897750By WAY you mean like 20% of 17 highway...so 20 highway?Whoa dude. Whooooaaaaa
>>28897765>Muh compact crossover :)Ok bud the lgbt board is that way you can head on home
>>28898975yeah, probably 3-4mpg but still that's a lot over time
>>28898980faggot.
I'm thinking about trading my c7 z06 for the GSX ngl
>>28899033Wait for the Z06X
I like how GM brought CPU/GPU type naming scheme to the car space. It's a good way to up-sell to customers and I'm surprised other manufacturers haven't tried it.>Yeah bro I got the 7950X3D
>>28897617>the entire powerband is torquey.How does /o/ STILL not understand how torque and horsepower work?
>>28899156he has a 90iq autistic fixation on convincing other people that pushrods are superior
>>28899163Could be worse. he could think rotaries are good.
>>28899185they are good for about 5 minutes
>>28897619t. Eurofag who has never driven a new Corvettes. New Corvettes have cylinder deactivation tech. In normal mode, if you don't push it, it only use 4 cylinders and drive like a Corolla. Now, bow down to the God mobile!
>>28899372I get 40 empeegees cruising at 40-45mph>>28897750What's ironic is that actually the high displacement naturally aspirated pushrod engine gets better fuel economy. Why is that? Pushrod engines are smaller and lighter. This allows them to be placed in small, lightweight, highly aerodynamic cars. Combined with cylinder deactivation and V4 mode, they actually get better fuel economy. All those TT 4.0L DOHC V8 engines are put in massive heavier cars, SUV/CUVs. They get more worse fuel economy than the light and nimble Vette. Simplicity wins the day.
