its not all about the revs and its not all about the exhaust system. A motorbike can rev to 15,000 and at the same time an F1 car will be already louder at 1500 rpm.
atleast in part why it sounds relaxed at 9000rpm is it's low piston speed at those rpm's because of it's super short stroke. @ 20000rpm it's piston speed is 87 feet per second. that is the piston speed of a chevrolet 350ci engine doing 9000rpm.
To anyone hating on F1 as a sport.... give me a break... to get an engine to spin this high is a fucking miracle of engineering... the only other thing in motorsport mechanics to equal this is a top fuel dragster engine.... equally impressive on my opinion.
@LanceCampeau 20,000rpm impressive? Yes the crank is spinning really fast, but these engines have such short strokes the average piston speed even at 20,000 rpm (assuming even a 2 in stroke) is "only" 6,666 fpm. Compare that to something like a pro mod engine with a 5.5 in stroke (or longer) at 8000rpm and you get, 7,333 fpm with a MUCH heavier piston. (of course, a drag race is also much shorter than a F1 race)
It surprised me a pro mod can have a faster piston speed than a F1.
@295walk Dont have a clue what the travellength is on a cars piston but for simplicty say halv a foot, but im sure its more but for now, but that would be a travellength of one full feet every revolution; a halv up a half down.
The rpm is 20000 at max so them multiply that with 1 feet and then divide it by 60 since we want the answer in seconds. That would be about 333 feet the distance a piston travels in that engine at that max rpm. Thats 227 mph.. faster then the car it self i think.
@dtiydr Yeah that sounds about right i dare say its more too. how can we work out the weight of piston ? Just goes to show the dynamic forces on the engine which it takes well
whats with the comments. to spare the confusion why dont you go out and grab your self's some real theory books instead of Wikipedia.. as for the guy talking bout vibrations.. thats why they dont go below a certain rev range when they are under load because the current style cranks are only balanced for a certain rpm band. Formula one is almost as restricted as nascar now.. mind you nascars fukin amazing. the nascar cranks get higher peak stress then f1 because of the borexstroke ratio.
@fergus1494 very true becuase American cars have to have large displacement with low revs. Anyways nascar, they only drive around on a banked oval. Nothing really spectacular. F1 tests the driver's ability to deal with speed, breaking, cornering, and G-Forces.
@OtherVincentLee hm, thats not taking into account the road races on actual tracks, although rare.. the part that makes me laugh is the aussie guy from v8 supercars is so much faster in the corners but once he is on the oval.. is average. Oval racing would have huge gee's and being such heavy high cars (for space frame racecars) im sure you would feel the gee's alot more. Due to the stroke of a nascar.. one sitting at 9k is like an f1 at 18,5-19k. Also Nascars sit at it all day, f1 dont.
But on that point, its possible to partially blame nascar for us manufacturers to be stuck in the 60's tech. Sorry to say mate but ford had the ohc 427 chev had the quad cam.. both canned because nascar banned them. Manufacturers then decided against production because they are short sighted. f1 is where Aero dynamic development really amazes me. Want amazing engines, look at topfuel. Almost compression locking each stroke with 3-4k hp big blocks revving at 9k rpm. Thanks for the reply mate :)
Yes, but you have a TURBO on it. Let's see what it makes without the turbo. 180Nm tops.
Also when you have a 2,4 litre engine making 750hp, torque is totally secondary. Heavy trucks need lots of torque to pull heavy loads. Light racecars need horsepower first.
@McLarenMercedes i know all that....was just kidding....btw i wouldn't say that torque is secondary because without thoose 270 Nm this engine wouldn't come even close to 750 hp...torque is low because of small cylinders,low compression and lightness of the engine itself
@3dule torque has nothing to do with the size of the cylinders or low compression. How would you explain diesels having compression ratios as high as 25:1?... Lightness of the engine?! just stop
@pettersaethre A drag motor is a racing motor, that why they call it drag racing.
Not just from a standstill, having more torque is useful anytime a car accelerates from one speed (even if it's 0mph) to another speed. However, F1 is more concerned about the overall shape of the torque curve over the rpm range used the most rather than making stump pulling torque they can't use anyways.
@pettersaethre And what is HP? Torque and rpm. So you want to maximize.... and this is the really important part I think you missed in my last comment.....you want to maximize average torque over the rpm range you're using. In other words it's better to have a flat torque curve (as the engine revs to peak HP) even in a narrow rpm range, than a peaky torque curve in that same rpm range. That's all I meant. :)
@dtiydr That's because of the room the engine is in. If you were to stand next to the car this was in, even at idle you would damage your ears. These things are so incredibly loud, louder than any else on earth in my opinion. The only thing I feel comes close is the Concorde and that is no longer in service.
Hey dealyvirusgiver, Ford sells more vehicles in Europe than BMW or Daimler. Must be a whole lot of blue collar folks in Europe huh? VW tops Ford but then a New VW is about half the price of any competitor.
Well unfortunately for you those Fords were designed and manafactured by Ford Cologne in Germany or Ford Great Britain. Not even the engines are from Detroit. Fact is the later generations Fords from Cologne, Germany have been starting to be sold in the States, like to Focus for instance.
BMW and Mercedes are for people with higher income of course more Fords will be sold. Hardly any Detroit Fords though. Pretty much none. No F150 trucks to be seen anywhere.
Can you make car? No but ford have don it for many years now ford is a good car i have one ford fiesta 1,3 i 1997 and trust me it move very good and fast acce to. And go very long on 1 L benzin
@ruffypoo By the usual machining :) The real answer is in engine design. These engines are generally severely oversquare with small cylinder displacement, advanced component mass reduction/metallurgy, rod length to stroke ratio and supporting valvetrain.
@2jzgtejza80 That's ridiculous! The motor in my car is a 400 big block bored 0.030 over (406 ci big block) or about 6.6 liters....I can't even imagine running twice as much displacement!
Buddy, thermodynamical and mechanical is impossible to reach 800hp from 6.6 liters at 5800rpm. Pushrods are lame, so your maximum power can be 500, and even that is too much. DOHC engines are much more powerful per displacement and they mostly produce power at high rpm, except Mercedes 6.2L
@2jzgtejza80 how do you figure its impossible? what about a diesel making 1000hp by 4k? Push rod motors make something those overcomplicated high revving engines do, its called torque. As far as 1/4 mile goes torque is the only thing that matters. Id take a pushrod v8 making 1000hp/1200lb.ft over a dohc 4cyl making 1000hp/600lb.ft any day.
Your pushrod is not diesel, and all diesels are turbocharged.
Next, pushrod (OHV) or DOHC, no matter, TORQUE depends about displacement and POWER depends about TORQUE produced through whole RPM range. At dyno you measuring TORQUE at RPM, than you calculating the POWER.
Next, for a 1/4 mile racing or acceleration racing you need much more than raw torque, it's called POWER to WEIGHT RATIO.
Next, why do you comparing 8 and 4 cyls engines??? it's not comparable.
@2jzgtejza80 First off, the two ARE comparable, seeing as cars with four cyl engines often have your almighty "power to weight" ratio on their side. Truth is, power to weight ratio doesn't make that much of a difference when you're lined up against the fucking fire-breathing, evil-sounding legend that is an American v8....more often than not, torque wins.
People like you never won anything. Circuit racing needs more than big blocks and torque. You are probably stuck in 20th century, in 50s, 60s, eventually 70s. Drag racing is boring, even in Europe this discipline is dead for decades. Only in US you can find rednecks running in 500-900CUI blocks with 16 spark plugs, 8 fuel pumps, nitromethan and huge non-efficient screw SCs. Corvette ZR1 is pure example that ''clever'' americans follow the Real MotorSport, same for new Stang Boss.
@2jzgtejza80 You say all that bullshit, but YOU'RE the idiot who thinks a pushrod v8 would struggle for 500 horsepower. Even an old American SMALL BLOCK v8 (GM 327 & 350, Chrysler 340, etc.) will easily reach 700 horsepower naturally aspirated. I'm not even going to talk about torque or your tiny little head might explode....
@2jzgtejza80 YOU missed my point. If a Honda Civic lines up against a big block muscle car at the drag strip, yes the civic is lighter and might even have a better power to weight ratio, but it's still going to lose. FYI drag racing is ALOT harder than it looks. BTW Here's what happens when an American muscle car from 40 years ago is modified for road courses: watch?v=7D4dpsC8eVE (skip to 5:40)
This video is good example, that STOCK american cars can't even touch European exotics on race track.
You need 572 stroker, 800hp, 1 million ft lbs, to win against Ferrari prototype with 500 hp max and engine 3 times smaller. DRAG RACING is SHIT. Real CAR potencial is on legendary Nurburgring, not straight line.
In this video Moddified Dodge can't even touch Ferrari in curves, just in straights. AGAIN, YOU MISS THE POINT. Civic is not drag car. FAIL AGAIN.
@2jzgtejza80 How the fuck is an f1 car an example of any of that? rofl. Anyway the viper acr has the 7th fastest time ever at nurburgring, the zr1 isnt too bar behind that. The only cars to beat the viper were 250k and up. Also the american cars added alot of safety equipment and used real street tires and the actual stock suspension that the car drove out of the shop with. Where as the the new gtr had no equipment and a modified suspension. Pretty lame to not run what ya brung.
@2jzgtejza80 Atleast american cars took an honest approach at it. Plus cost a fraction of any of those top cars. Besides american love drag racing and do it better then anywhere in the world. Different strokes for different folks. You dont have to like it. Also nascar v8's are pretty impressive, to run 10k for hours straight with no ill effects. Theres no slowing for corners, just a constant pounding. Pretty amazing imo. Also if those euro cars made any torque youd probably be into drag too.
@2jzgtejza80 Yeah but people do drag race civics...it was just an example. The Dodge could be a street-legal car with the mufflers on and with street-slicks instead of full race-slicks, and anyway, what do you expect in the corners from a car that weighs around 3,500 lbs? It still beats the ferrari back to the start-finish line...BTW the Dodges main modifications were to the body, suspension and brakes, any idiot can bore and stroke a hemi....that's not difficult at all.
@2jzgtejza80 You are trying way to hard to pretend like you know all, but your failing so hard at it. No not all diesels are turbo and yes diesels are push rod motors.
Really no need for a history lesson on hp vs tq. I think everyone clearly knows how they work. Well i hope so anyway.
No shit its about power to weight, thanks again captain obvious.
@2jzgtejza80 Why arent they comparable? A dohc 4cyl making the same power but at a much higher rpm will make no torque. A pushrod v8 making the same power as the 4cyl with make it much sooner and usually make more torque then hp. A diesel makign 1000hp will make 2k lb/ft and rip a 6000lb 4wd down the track faster then most 4cyl car weighing 2k or less. Or how about the camaros and corvettes still using push rod motors? If it aint broke dont fix it. zr1 is one of the baddest cars in the world
Buddy, why all americans must be stupid??? When you realize what you talking, than we can disscus on this.
Idiots comparing small 4cyls vs, V8 engines. Diesel engines produce massive torque, because of very long stroke, and 99,9 % of all produced DIESELS are turbocharged to make them more efficient. And whos talking about pushrods?? I said no matter what is OHV or DOHC, DISPLACEMENT is IMPORTANT.
Corvette ZR1 is astonishing, only good made in US, only comparable to great exotics.
@2jzgtejza80 You couldnt make it more obvious that your just another youtube import fanboy.
You are a complete idiot. A long stroke makes a high revving motor, which a fucking diesel is not. A cummings isb series. (top 10 best engine of 04) Had a stroke of 4.72", where as a smaller displacement ls1 had a stroke of 3.7. With long rod builds with a stroke as long a 6.7 in. If you honestly think a long stroke makes low end torque then you need to stop talking before you embarras yourself anymore
''A long stroke makes a high revving motor'' - MOST STUPID SENTENCE AND THE MOST UN-EDUCATED IDIOT ON YOU TUBE EVER. NOW YOU are on my list of MOST STUPID AMERICANS 1st. Watch BBC tonight, when I say to Formula 1 engineers what you said. OMG GOD take this people, world will be much better place to live.
Yes, long stokers makes more torque at low rpm, also depends about engine displacement and intake, designed to make more torque at lower rpm. All diesel are UNDERSQUARE cylinders.
@2jzgtejza80 Read a book man, honestly just type into google long rod vs short rod and try to learn something. rod/stroke ratio mean anything to you? Your attempts at insults on this page has only further prover your stupidity and pretend youtube knowledge. You can even make an argument that a long rod doesnt made a high revving motor. Its common knowledge. Nothing to argue dipshit.
@2jzgtejza80 The added displacement from the longer stroke may make more tq at similar hp. But thats again common knowledge that a larger displacement will make more tq at similar hp. This is in general ofcourse, but thats all void here anyway since any increase in displacement will yield similar results. Your not going to fool anyone here that your not completely full of shit. Maybe you should have attended an american school haha.
@nallen100 Actually man YOU need to stop speaking. A long stroke does make torque. Think of it as LEVERAGE. If you have a 6" pry bar you cannot pry very hard, but if you have a 2' pry bar you can pry very hard. Same concept. Stroke does equal torque, hence why Ford made the stroke exceptionally long in the 5.4 Triton motor. Small displacement yet still yields decent torque.
On top of that you cannot fit a 6.7" stroke in a LSX block. You MAY fit a 6.7" rod, but even then that is questionable.
@fastaslightning1 These are huge generalizations. The added torque comes from the added displacement. Dont confuse long rod vs long stroke. Those two are entirely different. Take the 2.0L 4g63. Using the 2.4 crank increases the stroke length creating a 2.3 stroker, making a low end torque monster. On the same not though, take the 2.0L and and use the long rod set up, and you get a the same 2.0L of displacement but now have a high revving screamer that revs out to 12k.
@nallen100 LOL! Revs to 12k? You have no idea the kinds of pressures, and stress 12k rpms creates. With the crank walk problems of a 4g63, I would NEVER rev it past 8500. No need. Thats what turbos are for. On top of that, I am not, nor have I ever mistook stroke for rod length. You are the one that said stroke creates a higher revving motor. Not me.
A 6.7 inch stroke will not fit in an LSX block. Considering the deck height is around 9" or so I seriously doubt a 6.7" rod would either
@fastaslightning1 rofl hahaha crank walk? are you shitting me. I bet $1000 you dont even know what cw is. cw only happened in 95-96 and only 7% of 4g's in those years every cw. Talking about a very small number there. Turbo does not make up for rpm. no clue what your getting at there. 6.1" rod is the longest you can safely go before needing serious work but it is very possible.
@nallen100 Yeah, fucking crank walk, where the end play on a crank gets too loose, and the crank, which has forces front and back as well as along it's length, moves too far back, ruining the bearings and destroying the crank in the process. I will guarantee I know more about engines than you will ever.
6.1 inches is a far cry from 6.7.
As far as turbos making up for RPM, you are SADLY mistaken. Turbos make great torque, and the added air, will make a smaller engine act like larger
@fastaslightning1 Fat chance of you knowing more then me. Because you are dead wrong already...cw is caused by the thrust bearings. not the by the crank dipshit. In 95-96 the bearing design caused only 7% of the cars in those two years to walk. The bearing was redesigned in 97+ and never happened again. Any car can crankwalk. The 6.1 is w/o mods. 6.7 needs some work, not a big surprise though.
No one needs a lesson on how turbos work. They still dont make up for rpm, they need rpm to spool up.
@nallen100 Crank walk has many factors, not the least of which is how the crank is machined on the matching face. Not only that, but cars had issues well into the 99 model year, and all you have to do is a simple google search for that. Guys with 99DSM's that had the engine replaced under warranty. So never is a mighty tall tale.
@nallen100 The deck height on a LSx is 9.24 inches, with a 6.7" rod you have less than 3 inches for your compression height and stroke.Add in stock 5.7 stroke and you are 8.51. That leaves less than .75 for your compression height, not including that your piston pin will be into your second ring land. This will cause severe oil control issues. Minimum should be around .815, and the piston pin is still into the oil ring but that is OK. Unless you are using a 4.8 crank (why?) a 6.7 aint happening
@fastaslightning1 Your logic is very flawed. The factory and most aftermarket 350 pistions have a compression height of 1.56". You can also run zero deck height. That set up ofcourse would be very extreme and not for a street car. Similar to filling a block, ofcourse it hurts cooling but same idea. Thats all i was getting at.
@nallen100 You are truly showing what you do not know. LS1 motors have a small positive deck height. Not only is that for the street, but STOCK. It still would not allow for enough ring pack to not burn oil, and would effect the cylinder seal. I don't give a shit what a SBC compression height is, we are not talking about that. Yes the pistons stick out of the block, and into the head gasket area to help with quench. It still isn't feasible to run a .74 CH. The ring package is too compromised
@nallen100 The ring package is too compromised for ANY ENGINE, not just a street car. No engine would be worth a shit for any competition while burning oil and carboning up. It is nothing like filling the block or not running a WP. Nothing. One is possible, the other would lead to broken ring lands, pushed through pistons, oil consumption at an alarming rate, and even failure if the competition lasted more than a few seconds. Even then in drag racing you can not oil down the track
@fastaslightning1 There is way way more to it then that. Head cc size, what crank your running, you can offset the crank, piston shape and design, etc. Alot of small block guys are able to pull a low 8.5:1 comp ratio with 6" rods for boosted builds.
@nallen100 WTF ARE YOU TALKING ABOUT?! 6 inch rods are almost 3/4ths of an inch SHORTER! Of course they can do that, jesus fucking christ you are stupid. I don't care about small block guys, and boosted builds. We are NOT talking about that. Fuck your head size, it is up your ass!
The compression ratio has little to do with rods either! Piston design and head design, but again, what does that have to do with a 6.7" rod like you stated? What crank? You mean stroke.......ah fuck it you are lost
@fastaslightning1 Do not one of your answer has had an factual info whatsoever. Your know it all attitude on crank walk was as completely wrong as possible. No where near a correct answer. I mentioned the low compression on 6" rods because if their able to pull off 8.5. Thats incredibly low when talking about purpose built motors. 12:1 is still very low, i will be running 12:1 on my next boosted build, get it??
@fastaslightning1 Yes stroke of the crank(shorter), cut of the crank, cc of the head, what piston all matter. Then after that you can still sink the pin deeper in the piston. Do you realize how small less then 3/4 an inch is lol. Take out the ruler you use to measure your dick now add a 1/4". Pretty small isnt it. You keep bringing up the lsx motors. Im talking about old small blocks.But who cares you probably dont even have a car...youtube racer.
@nallen100 You are right, I don't have a car, I have 7 you moron. I have built more cars than you have ever sat in. You want to talk about old small blocks now? Because in your first comment you said LS1. That isn't an old small block ya fucktard. Fine, old small blocks are WORSE. They had a 9.025 deck height, which means even less compression height, fucking tard. In engines .0001 can be too much, so .74 is HUGE. The cut of the crank does not matter in CH, the block gets in the way long before
@fastaslightning1 7 cars yet only a couple of real goofy rodeo vids. Is that you on the horse rofl? Everyone in my family races, i guarantee ive sat in and driven nicer, faster cars then youve ever even thought about building. So stick to you brokeback horse club and quit youtube racing. I bet my mostly stock 4cyl car is faster then anything you have. Btw you can clearance the block dipshit, extremely common. Long rod, short stroke crank, big cc head, dished pistons,i said max not common builds
@nallen100 Ohhh, I haven't posted 890 car videos, so I am not a real car guy. Man STFU. You are now attacking the person since you know you know absolutely shit about engines. I don't give a fuck if your dad is Smokey Yunick, you know fuck all about engines.
So now you want to clearance the block for a SHORT crank? Just STFU, you know you don't know shit.
Bring your 4cyl here I will fuck it up with my diesel. Your junk couldn't beat my work truck.
@fastaslightning1 Again you dont give out one single fact. More random gibberish and insults. Get over yourself. If your such an amazing engine builder, what are you doing spamming the shit out out of youtube lol. Your the asshole talking about the crank hitting the block dipshit. Which a monkey can fucking do. If your truck runs lows 12's then it will beat me. But ive only had the car for 2 months so big deal

@3dule
Yes, but you have a TURBO on it. Let's see what it makes without the turbo. 180Nm tops.
Also when you have a 2,4 litre engine making 750hp, torque is totally secondary. Heavy trucks need lots of torque to pull heavy loads. Light racecars need horsepower first.
McLarenMercedes 2 months ago
@McLarenMercedes i know all that....was just kidding....btw i wouldn't say that torque is secondary because without thoose 270 Nm this engine wouldn't come even close to 750 hp...torque is low because of small cylinders,low compression and lightness of the engine itself
3dule 2 months ago
@3dule torque has nothing to do with the size of the cylinders or low compression. How would you explain diesels having compression ratios as high as 25:1?... Lightness of the engine?! just stop

pettersaethre 4 months ago
@pettersaethre A drag motor is a racing motor, that why they call it drag racing.
Not just from a standstill, having more torque is useful anytime a car accelerates from one speed (even if it's 0mph) to another speed. However, F1 is more concerned about the overall shape of the torque curve over the rpm range used the most rather than making stump pulling torque they can't use anyways.
Warblade118 4 months ago
@Warblade118 they drive the track at near max rpm, so torque is less important then hp. its the same ting with your nascar..even more so actually
pettersaethre 4 months ago
@pettersaethre And what is HP? Torque and rpm. So you want to maximize.... and this is the really important part I think you missed in my last comment.....you want to maximize average torque over the rpm range you're using. In other words it's better to have a flat torque curve (as the engine revs to peak HP) even in a narrow rpm range, than a peaky torque curve in that same rpm range. That's all I meant. :)

DeAdiSSu3 8 months ago
@DeAdiSSu3
Buddy, thermodynamical and mechanical is impossible to reach 800hp from 6.6 liters at 5800rpm. Pushrods are lame, so your maximum power can be 500, and even that is too much. DOHC engines are much more powerful per displacement and they mostly produce power at high rpm, except Mercedes 6.2L
2jzgtejza80 8 months ago
@2jzgtejza80 how do you figure its impossible? what about a diesel making 1000hp by 4k? Push rod motors make something those overcomplicated high revving engines do, its called torque. As far as 1/4 mile goes torque is the only thing that matters. Id take a pushrod v8 making 1000hp/1200lb.ft over a dohc 4cyl making 1000hp/600lb.ft any day.
nallen100 8 months ago
@nallen100
Your pushrod is not diesel, and all diesels are turbocharged.
Next, pushrod (OHV) or DOHC, no matter, TORQUE depends about displacement and POWER depends about TORQUE produced through whole RPM range. At dyno you measuring TORQUE at RPM, than you calculating the POWER.
Next, for a 1/4 mile racing or acceleration racing you need much more than raw torque, it's called POWER to WEIGHT RATIO.
Next, why do you comparing 8 and 4 cyls engines??? it's not comparable.
2jzgtejza80 8 months ago
@2jzgtejza80 First off, the two ARE comparable, seeing as cars with four cyl engines often have your almighty "power to weight" ratio on their side. Truth is, power to weight ratio doesn't make that much of a difference when you're lined up against the fucking fire-breathing, evil-sounding legend that is an American v8....more often than not, torque wins.

People like you never won anything. Circuit racing needs more than big blocks and torque. You are probably stuck in 20th century, in 50s, 60s, eventually 70s. Drag racing is boring, even in Europe this discipline is dead for decades. Only in US you can find rednecks running in 500-900CUI blocks with 16 spark plugs, 8 fuel pumps, nitromethan and huge non-efficient screw SCs. Corvette ZR1 is pure example that ''clever'' americans follow the Real MotorSport, same for new Stang Boss.

If a Honda Civic lines up against a big block muscle car at the drag strip, yes the civic is lighter and might even have a better power to weight ratio, but it's still going to lose.

Theres no slowing for corners, just a constant pounding. Pretty amazing imo. Also if those euro cars made any torque youd probably be into drag too.

@2jzgtejza80 Why arent they comparable? A dohc 4cyl making the same power but at a much higher rpm will make no torque. A pushrod v8 making the same power as the 4cyl with make it much sooner and usually make more torque then hp. A diesel makign 1000hp will make 2k lb/ft and rip a 6000lb 4wd down the track faster then most 4cyl car weighing 2k or less. Or how about the camaros and corvettes still using push rod motors? If it aint broke dont fix it. zr1 is one of the baddest cars in the world

Idiots comparing small 4cyls vs, V8 engines. Diesel engines produce massive torque, because of very long stroke, and 99,9 % of all produced DIESELS are turbocharged to make them more efficient. And whos talking about pushrods?? I said no matter what is OHV or DOHC, DISPLACEMENT is IMPORTANT.

You are a complete idiot. A long stroke makes a high revving motor, which a fucking diesel is not. A cummings isb series.

Its common knowledge. Nothing to argue dipshit.
nallen100 8 months ago
@2jzgtejza80 The added displacement from the longer stroke may make more tq at similar hp. But thats again common knowledge that a larger displacement will make more tq at similar hp. This is in general ofcourse, but thats all void here anyway since any increase in displacement will yield similar results. Your not going to fool anyone here that your not completely full of shit. Maybe you should have attended an american school haha.
nallen100 8 months ago
@nallen100 Actually man YOU need to stop speaking. A long stroke does make torque. Think of it as LEVERAGE. If you have a 6" pry bar you cannot pry very hard, but if you have a 2' pry bar you can pry very hard. Same concept. Stroke does equal torque, hence why Ford made the stroke exceptionally long in the 5.4 Triton motor. Small displacement yet still yields decent torque.
On top of that you cannot fit a 6.7" stroke in a LSX block. You MAY fit a 6.7" rod, but even then that is questionable.
fastaslightning1 8 months ago
@fastaslightning1 These are huge generalizations. The added torque comes from the added displacement. Dont confuse long rod vs long stroke. Those two are entirely different. Take the 2.0L 4g63. Using the 2.4 crank increases the stroke length creating a 2.3 stroker, making a low end torque monster. On the same not though, take the 2.0L and and use the long rod set up, and you get a the same 2.0L of displacement but now have a high revving screamer that revs out to 12k.
nallen100 8 months ago
@nallen100 LOL! Revs to 12k? You have no idea the kinds of pressures, and stress 12k rpms creates. With the crank walk problems of a 4g63, I would NEVER rev it past 8500. No need. Thats what turbos are for. On top of that, I am not, nor have I ever mistook stroke for rod length. You are the one that said stroke creates a higher revving motor. Not me.
A 6.7 inch stroke will not fit in an LSX block. Considering the deck height is around 9" or so I seriously doubt a 6.7" rod would either
fastaslightning1 8 months ago
@fastaslightning1 rofl hahaha crank walk? are you shitting me. I bet $1000 you dont even know what cw is. cw only happened in 95-96 and only 7% of 4g's in those years every cw. Talking about a very small number there. Turbo does not make up for rpm. no clue what your getting at there. 6.1" rod is the longest you can safely go before needing serious work but it is very possible.
nallen100 8 months ago
@nallen100 Yeah, fucking crank walk, where the end play on a crank gets too loose, and the crank, which has forces front and back as well as along it's length, moves too far back, ruining the bearings and destroying the crank in the process. I will guarantee I know more about engines than you will ever.
6.1 inches is a far cry from 6.7.
As far as turbos making up for RPM, you are SADLY mistaken. Turbos make great torque, and the added air, will make a smaller engine act like larger
fastaslightning1 8 months ago
@fastaslightning1 Fat chance of you knowing more then me. Because you are dead wrong already...cw is caused by the thrust bearings. not the by the crank dipshit. In 95-96 the bearing design caused only 7% of the cars in those two years to walk. The bearing was redesigned in 97+ and never happened again. Any car can crankwalk. The 6.1 is w/o mods. 6.7 needs some work, not a big surprise though.
No one needs a lesson on how turbos work. They still dont make up for rpm, they need rpm to spool up.
nallen100 8 months ago
@nallen100 Crank walk has many factors, not the least of which is how the crank is machined on the matching face. Not only that, but cars had issues well into the 99 model year, and all you have to do is a simple google search for that. Guys with 99DSM's that had the engine replaced under warranty. So never is a mighty tall tale.
fastaslightning1 8 months ago
@nallen100 The deck height on a LSx is 9.24 inches, with a 6.7" rod you have less than 3 inches for your compression height and stroke.Add in stock 5.7 stroke and you are 8.51. That leaves less than .75 for your compression height, not including that your piston pin will be into your second ring land. This will cause severe oil control issues. Minimum should be around .815, and the piston pin is still into the oil ring but that is OK. Unless you are using a 4.8 crank (why?) a 6.7 aint happening
fastaslightning1 8 months ago
@fastaslightning1 Your logic is very flawed. The factory and most aftermarket 350 pistions have a compression height of 1.56". You can also run zero deck height. That set up ofcourse would be very extreme and not for a street car. Similar to filling a block, ofcourse it hurts cooling but same idea. Thats all i was getting at.
nallen100 8 months ago
@nallen100 You are truly showing what you do not know. LS1 motors have a small positive deck height. Not only is that for the street, but STOCK. It still would not allow for enough ring pack to not burn oil, and would effect the cylinder seal. I don't give a shit what a SBC compression height is, we are not talking about that. Yes the pistons stick out of the block, and into the head gasket area to help with quench. It still isn't feasible to run a .74 CH. The ring package is too compromised

@nallen100 The ring package is too compromised for ANY ENGINE, not just a street car. No engine would be worth a shit for any competition while burning oil and carboning up. It is nothing like filling the block or not running a WP. Nothing. One is possible, the other would lead to broken ring lands, pushed through pistons, oil consumption at an alarming rate, and even failure if the competition lasted more than a few seconds. Even then in drag racing you can not oil down the track
fastaslightning1 8 months ago
@fastaslightning1 There is way way more to it then that. Head cc size, what crank your running, you can offset the crank, piston shape and design, etc. Alot of small block guys are able to pull a low 8.5:1 comp ratio with 6" rods for boosted builds.

Everyone in my family races, i guarantee ive sat in and driven nicer, faster cars then youve ever even thought about building. So stick to you brokeback horse club and quit youtube racing. I bet my mostly stock 4cyl car is faster then anything you have. Btw you can clearance the block dipshit, extremely common. Long rod, short stroke crank, big cc head, dished pistons,i said max not common builds

@nallen100 Ohhh, I haven't posted 890 car videos, so I am not a real car guy. Man STFU. You are now attacking the person since you know you know absolutely shit about engines. I don't give a fuck if your dad is Smokey Yunick, you know fuck all about engines.
So now you want to clearance the block for a SHORT crank? Just STFU, you know you don't know shit.
Bring your 4cyl here I will fuck it up with my diesel. Your junk couldn't beat my work truck.

@fastaslightning1 Again you dont give out one single fact. More random gibberish and insults. Get over yourself. If your such an amazing engine builder, what are you doing spamming the shit out out of youtube lol. Your the asshole talking about the crank hitting the block dipshit. Which a monkey can fucking do. If your truck runs lows 12's then it will beat me. But ive only had the car for 2 months so big deal
