GM's new Boomer LS6 engine.During development, engineers where unable to reach power goals.They continued to use state of the art ai assisted CAD software without success.Software engineers where unable to put in design parameters that resulted in more power.They were stumped.Until some random boomer from the Race department walked in and said:"intake port is large enough for 750horsepower but those valves are for a 500hp engine".So they decided to give the boomer a prototype head.The old boomer dude raises the port, adds epoxy and reduces the size by 20%.Engine picks up tons of power.Boomer redesigns their intake and makes a tunnel ram design.Makes even more power.GM ends up using both in the final design.Boomer shit: 1Multi million dollar engine software: 0
>next generation>pushrod engines in 2026 when almost every other engine switched decades ago to twin camscringe
computers are crutches for retards
>>28931823Ohv tork tho
>>28931821>shitrod engine makes poo power because shitrods>needs boomer engineering just to eek up 530hp while the new software designed DOHC engine makes 670Get wrecked boomers, technology chads on top
>>28931823This. It's fucking embarrassing at this point honestly.
>>28931821>And then everybody clapped.
>>28931823Chud seethes over proven systems. Shits his pants to see something JustWork>>28931824Factual, this is even more observable amongst motorcycles as all new bikes does 80% of the skill work for you.
>>28931885>>28931886>>28931823What do you mean its making more power than the gen 4 coyote
>>28931885GM's 632 crate engine makes over 1000hp NA on pump gas. Making big all motor power with a small block has never been cheap or easy and it's even harder when you have production car bullshit to deal with. The whole point of pushrods is the displacement advantage. Lets see some 1000+hp NA DOHC pump gas crate engines under $100k.
cringe the audi 5 banger is the only kino engine left
>>28931898Yeah with an extra 2 liters retard. It's pathetic.
>>28931903Any manufacturer on the planet can make 1000hp with 10 liters of displacement lol.
>>28931915>t. wrenchlet
this is the kind of boomer fantasy that makes it's rounds on the facebook car pages.
>>28931823It's nice having something different
>>28931898Cool, but this isn't a GM vs Ford thread - this is a boomer pushrods vs Technology thread, and the Corvette Engine which uses technology moggs it.
>>28931903Wow it makes twice as much power as a K24 crate motor which has 1/4 of the displacement!
>>28931830>ohv
>>28931823>using internal combustion at all when electric has more torque and horsepowerThis is what you sound like.
>>28931968Oh look the bus rider that thinks peak numbers on a piece of paper is all that matters....
pushrods push gods
>>28931927>muh hp per literdisplacement cope every time
>>28932057LOL
>>28932059>"LOOK AT THESE PEAK NUMBERS!!!"Those peak numbers are pretty crap 2bh>"PEAK NUMBERS DON'T MATTER ANYWAY!!!"So why did you bring it up lmao?Cope harder.
>>28932063Ok so go with the apples to apples comparisonYou won't because you get MOGGED
>>28931823I can appreciate how far Gee Em has pushed those fucking rods, but this guys right, it's cringe
>muh pushrods>_ONLY_ 530 HP>Koenigsegg has a 2.0t I3 that puts out 600 HP>MOGGED
>>28931968here's 6.2l vs 1.8l
>>28932145
>>28932089GM just wants to build a smaller, lighter engineobviously that's what all the retards in this thread want, right?
>>28932145>>28932146>>28932149Wow cool! Here's a shitrod V8 vs a DOHC V8 with the exact same engine block.
>>28932149>1000hp heads vs 3000hp heads
>>28931915RIP>>28931950Truth.>>28932057If you're just autistically into big numbers... yeah. You've already sacrificed your fun by ditching manuelle.>>28932143One of the few times when a V8's the npc option.
>>28932071You dont understand how "under the curve" relates to performance.Having an engine with a dyno plot that looks like the silhouette of Mt. Everest is absolute garbage unless youre bouncing off the red limiter 99% of the time.While youre trying to spool the pushrod is doing a fucking wheelie 2 car lengths ahead of you.Do you even have a car?Post pics.
>>28931821Makes sense. The boomer was using a bespoke multi-modal neural network fine tuned on high output engine design data.
>>28932169>quotes peak power>gets btfo on peak power>"B-B-B-BUT WHAT ABOUT UNDER THE CURVE??????"What other metric shall we pivot too next?Fuel efficiency? Reliability?
>>28932163>27 liters>2000lb >600hp on a good day Aero engines were fun when you needed bragging rights post-war, but they're just show car fodder nowadays.
>>28931823>disrespecting pushGODScringe
>>28932175>not doing something cool just because you can Jews really did a number on the minds of men
>>28932179Americans should be using Allisons anway
>>28931885There's a 200ft-lb difference between those two engines though.The DOHC LT6 makes 300lbft at 3,000rpm.That new LS6 is making 510lbft at 3,000rpmEven peak to peak, there's a 100lbft gap.Having that amount of torque means way better acceleration.
>>28932220>Having that amount of torque means way better acceleration.Hello boomer, gears existWheel torque is a thing and the engine with the most power has the most wheel torque.
>>28932173What a fucking retard.My original post states that peak numbers are not a viable metric you ESL third worlder faggot.
>>28932230>GM's 632 crate engine makes over 1000hp NA on pump gas. Making big all motor power with a small block has never been cheap or easy and it's even harder when you have production car bullshit to deal with. The whole point of pushrods is the displacement advantage. Lets see some 1000+hp NA DOHC pump gas crate engines under $100k.ctrl+f "under the curve"no results
>>28932222>Hello boomer, gears existand what happens if you put those same gears in the torquier motor
>>28932239You have a lower road speed and need to pick the next gear, with a worse multiplier, to match the same road speedYOU ABSOLUTE FUCKING RETARD This is literally what the horsepower metric means
>>28932220>Having that amount of torque means way better acceleration.>spins tires and goes nowhere
>>28932243then why is the new one faster?
>>28932255[citation needed]
>>28932260first cite me a wheel torque chart comparing the two drivetrains with their respective production gearing to prove that the dohc motor has the advantage you claim it does. (hint, you won't because it doesn't)
>>28932274>(hint, you won't because it doesn't)
>>28932274>makes claim>can't back it up Lmao>first cite me a wheel torque chart comparing the two drivetrainsTHAT'S LITERALLY WHAT HORSEPOWER IS YOU FUCKING RETARDTHE DYNO JUST READS THE WHEEL TORQUE, HIGHER HORSEPOWER = HIGHER WHEEL TORQUEIt needs an RPM signal to figure out whether it's a low RPM, high torque engine with a long gear or a high RPM, low torque engine with a short gear, otherwise the dyno does not know or care - it just measures wheel torque and road speed.
>>28932276i accept your concession and acknowledgement of my superiority and much larger dick size (both length and girth).
>>28932189Wrong type of human bean.
>>28932280>tfw dick too big to understand what horsepower means
>>28932278production hp figures are crank hp my man.
>>28932287Did you think you were making a point here?Did you think that in any way invalidates my point, like you expect the engine which has lower crank horsepower to somehow magically have higher wheel horsepower?
>>28932232Thats not my post you schitzo faggot.
>>28932295and yet you are replying for him, curious
>>28932292if the gearing is different, which it is, then yes i do.
>>28932222>Hello boomer, gears exist Do you have some sort of magic wand that allows you to just ignore RPM? Do you think a more torque'y engine can't also use more aggressive gearing? >>28932250It's not like you're going to spend tires with a 345 rear tire on a mid Engine car.Not Lisa modern car that has a sophisticated traction control system.
>>28932300You believe that the 530hp engine will make more wheel horsepower than the 670hp engine?
>>28932306>horsepower... what does it meanIf the lower RPM more torquey engine has the same gearing, it will be at a lower road speed you retard. In order to achieve the same road speed it will need to have higher gearing with a worse torque multiplication which will result in lower wheel torque than the engine which has more power.This shit isn't complicated, it's entry level car knowledge - THIS IS WHAT THE HORSEPOWER CALCULATION IS FORMORE HORSEPOWER = MORE WHEEL TORQUE AT A GIVEN ROAD SPEED
>>28932297>omg someone else replied to my post!!!Holy fuck youre an idiot.My comment was directly aimed at>Wow it makes twice as much power as a K24 crate motor which has 1/4 of the displacement!Jesus christ, how fucking new are you?Nit only tjat but youre not even addressing what I said.Youre just on some weird tangent.Take your fucking meds.Better yet, get off this board.
>>28932325That's because you shifted the goalposts from the original post buddy, whether or not you're the same person is irrelevant - those are the goal posts being discussed.
>>28931823>cheaper to produce>far more simple mechanically >vastly superior torque and hp curvesMaybe pushrods were the standard in the first place for a reason.
>>28932346>opening your valve with a rod somehow magically makes the torque and hp curve better
>>28932074I'm not building an apples to apples car fucktard I'm building a car that's faster than yours.
>>28932312are you yelling me you couldn't gear the higher torque engine to be faster than the lower torque engine?
>>28932348>can't rev won't rev better tune for low end
>>28932375I'm telling you that if they were both geared for the same road speed, the higher horsepower engine would make more wheel torque, regardless of whichever has the higher engine torque.That is what horsepower means retard-kun, try learning about the absolute BASICS of automotive knowledge before posting on the aut/o/motive board.
>>28932379>heh.... I always liked low end torque better anyway...
>>28931821Boomers learned porting and polishing from their parents.Don't act like they invented it.
>>28932382nah sorry but this is wrong. feel free to post a wheel torque chart of the two to prove me wrong though.
>>28932348>Changes a physical component >Alters the physics of the machine Somehow, people like you are suprised by this. NGMI
>>28932318What are you even talking about?
>>28932458So you mean I can just add some extra rods to my Civic engine and magically make more torque?
>>28932563You're being silly anon and you know it.
>>28932563the rods will let you make a physically smaller engine so you can increase the size of other parts like valves so they flow the same (or more) amount of air than you could before
>>28932563Ignoring the shit posts, OHV engines typically have much better low and mid valve lift flow and velocity.They tend to make more torque in those RPM ranges because of that.While something like a 4V 5.0L coyote head has a large intake runner cross sectional area.That means lower velocity at lower valve lifts and engine speed.It's unavoidable with a single intake runner and 2 intake valves.But the CFM flow per CC/size is pretty good, that means better high RPM flow.That's a big part of why those make 500hp with 5.0L.(there are other factors)But the lower end torque is pretty bad If you drive a dark horse or Mach1, it's pretty clear it just doesn't have the mid range grunt of the GM LT1/2.Those 5.0L feel sluggish below 4,000rpm.Then start to come alive after.
>>28931823>cringeExactly.This is literally the worst version of "We Wuz".
>>28932598>>28932571This makes zero sense. You're literally parroting boomer tier lore.Absolutely nothing about OHV innately or inherently alters the port geometry.Nor does it alter the lift profiles, the valve size, literally anything.They make low end power because they are designed to. That's it.
>>28932612>inherently alters the port geometry. Anon, have you looked at a OHV port vs a DOHC port?The cross sectional area is MASSIVEIt has to be, in order to feed 2 valves
>>28932612Then compare to a typical LS Cathedral port.20cfm ish less but the LS port has 1/3 the cross sectional area.Port velocity is more than 2x the Coyote port.
>>28931927>2 more liters of displacement>engine is actually smaller in total sizeWhy care about hp/L when you can add more L for free? Are you some eurobrained retard from some displacement-taxed shithole?
>>28932327Alright, let's play.What goal post specifically?>engine is the same physical size, twice the power, 4x the displacement.I already know youre a euorpoor because you've been indoctrinated since birth to believe efficiency is the most important aspect of life.>the politicians that decided on a displacement tax on The Poors (you) are chaufered in limousines to the airport to board a private jet for their monthly "vacations" to a private island.So what's the issue here?That i paid $3.59 for a gallon of gas today?Are we talking about HP/L?What about HP/LB?Isn't weight the biggest issue in your fantasy world?
>>28932612it doesn't but you do get more room to do shit like what the boomer in OP's story did. and the pushrod engine valves are already huge which is also why GM don't bother going multi-valve - the engine already flows enough air for their needs.
>>28932418Yeah no worries retard-kun, here you go:>530hp ÷ road speed = X wheel torque>670hp ÷ road speed = more wheel torque
>>28932458You gunna explain the specific details of how that works?>>28932598Is there any reason you can't achieve the same low and mid valve flow flow and velocity with OHC?(protip: there isn't)>>28932628>It has to be, in order to feed 2 valvesWhy do you think 2 intake valves is a pre-requisite for OHC?
>>28932678>engine is the same physical size(it's not)
>>28932690You have less room for intake ports on a pushrod engine you retard and you can put one big massive valve on ANY engine, the reason manufacturers choose multiple smaller valves is because:>A - you can occupy more area of a circle with 4 small circles than 2 big ones>B - a large heavy valve requires a lot of spring pressure to control at high RPM
ohv is an improvement over ohc
>>28932722that's not taking gearing into account.
>>28932733>what is road speedHello retard-kun!
>>28932738you keep calling me a retard and it's pretty obvious you're just projecting at this point.
>>28932744That's because you're too retarded to understand the very basic metric we use to measure the output power of engines, yet here you are on the aut/o/motive pretending to be an auto enthusiast.LS6:> 520 lb⋅ft at 4,600 rpmLT6: 460 lb⋅ft at 6,300 rpmTo make the 6,300 rpm LT6 spin at the same speed as the 4,600 LS6 you would need to run it through a 1.37:1 gear reduction.The 1.37:1 gear reduction would multiply the LT6 torque to 630 lb⋅ft.REALLY SIMPLE STUFF RETARD-KUN
>>28932724You were BTFO by a reddit image.>>28932146Thats how shit your game is.People in Nepal that have never seen a car in person know more than you. But they have starlink and theyre laughing their asses off at your retarded posts right now.
>>28932726>You have less room for intake ports on a pushrod engineMopar Hemi says otherwise.
>>28932751I can see why everybody here is so fat. I get the feeling nobody here rode bicycles as a kid. If they did easy concepts like power, torque and gearing would be pretty easy to understand. People like you seem to be struggling with the subject.
>>28932766>maybe if we leave the accessories on the smaller engine it will look as big as the bigger engine when we photograph them from the frontPushrod enthusiast have a low enough IQ that this works on them.>>28932770Specifically by what mechanism does the mopar achieve more room for the intake ports than an OHC engine?
>>28932772>retard-kun gets btfo by basic facts and logic>"Y-Y-YOU JUST DON'T UNDERSTAND THE SUBJECT!!!!!"Complete non-rebuttal, I accept your concession retard-kun.
>>28932722This nigga doesn't know the difference between horsepower and torque
>>28932751unless the LT6 has a 6k stall converter which it doesn't the LS6 will smoke it from a dig. that lack of torque down low will kill it off the line.
>>28932826>but what if we setup the gearing and launch RPM for the higher horsepower engine wrong?!!!!>THEN IT WOULD BE SLOWER!!!!! Truly a genius insight anon
>>28931823>mechanically simpler>easier for mechanics to work on>the head is shorter so it fits under miata's hoodfor the downside of...
>>28932849do you think a Z06 comes with a 6k stall?
>>28932864I think the Z06 is set up to utilise its engine HP as optimally as the Grand Sport is, which is why it manages to accelerate faster with that greater HP.
>>28932885source?
>>28932886GM put it into the higher trim car
>>28932598'Yotes hit 200 whp by 3k and have a 2000 rpm >400 whp powerband.It's a good engine.If you want to compare some 6.2+L ls to a ford 5.0 start by multiplying ford's numbers 20%...
>>28932892LOL
>>28932774>specifically by what mechanism does the mopar achieve more room for the intake ports than an OHC engine?Ok.So youre a fucking retard basement dwelller nowrench faggot that took the bait.So guess what.IT DOESNT FUCKING MATTERThe combustion chamber doesnt care if its OHV or OHC.Eat a dick, eurotrash
>>28932902prove me wrong
>>28932909grandsport hasn't even been released yet you fool no one knows how fast it is.
>>28932925Except for retard-kun, he KNOWS >>28932255
>>28932931ok so you're equally as retarded as that guy. congrats, retard.
>>28932885>>28932892You do know a Z06 is only .1s quicker to 60mph than a Z51 right? There's a good chance with the extra power and torque over a Z51 the GS it'll eclipse the Z06 off the line.https://www.caranddriver.com/reviews/a29462701/2020-chevy-corvette-by-the-numbers/https://www.caranddriver.com/reviews/a41725834/2023-chevrolet-corvette-z06-by-the-numbers-november-2022/
>>28932318>MORE HORSEPOWER = MORE WHEEL TORQUE AT A GIVEN ROAD SPEEDThis anon is correct:At a given road speed, the vehicle with the higher horsepower is producing more energy per second. Because of how transmissions work, that extra energy can be converted into more twisting force at the wheels through gearing.
>>28932946.2 seconds anon, why you gotta lie? And you think 40 extra horsepower will knock .2 seconds off the 0-60?
>>28933246No, totally. All you need is to tow a boat with a Hayabusa engine is some crazy mad gearing bro. It's the same thing , no difference because of Horsegears and torquespeeds
>>28933251>No, totally.Nope bro....In the world of internal combustion, torque is the "egg" and horsepower is the "chicken."
>>28933251BTW, this is why Dyno Charts always cross HP and Torque at 5252 rpm.If NOT, then it's a fake chart.
