Well... no. To explain it a bit it's because for a few decades now, high end car manufacturers have been designing and tuning their exhaust pipes to have particular and distinctive tones and at times even the cabin itself to produce those lovely roaring engine sounds. It really depends on the exhaust they make for it.

Jason I know you aren't a motorcycle guy, but modern sportbike engines are capable of incredible feats worth discussing (squeezing 300+ horses out of a 1-liter inline-four), I'd love to see a video about one of those.

German manufacturer are actually moving away from downsizing. BMW planned to introduce the 3 cylinder into a large portions of it’s models but they are now reversing the trend. Which does not mean that engines are becoming bigger but they will focus on 2L inline-4 cylinders and 3L inline 6-cylinders. Although I hope they keep the 4.4L V8 a bit longer as well.
That's kinda last generation actually! Back in the day, lots of people just neglected oil changes and drove until they needed an engine rebuild, because that only costed like 100 bucks, maybe less lol!
Tbh that pretty much sums up any German engine designed in the last 10 years! They are so stupidly complex there is little point in trying to maintain them after a certain mileage, you just throw away the whole car!
At the same time though, how many of these cars reach 100,000km? The Mclaren F1 has been around for almost 30 years now and I doubt more than a handful of the production run have even reached 50,000KM let alone 100,000KM.
You mean the extra tender spring on the suspension? Nothing really special about it. It's just a spring with a rate tuned specifically to the behavior of the aero package to counter sporadic and rapid oscilations

@@charlie_mk7.5 Early Ferraris were small displacement v12s. Formula one in the late 60s was 3 liters and many of those engines were 12s and the infamous BRM was 16 cylinders.
"Size does matter... for engines." That gave me a good laugh. 😂 I know it's an extremely unpopular opinion but I've never really liked Aston Martins much but I'm in love with the Valkyrie and it's engine. Amazing looking and impressive engineering.
But... do they really need that much down force to keep the traction needed to accelerate??? Or did they over engineer that factor??? They could lighten the weight of the engine a lil more if not...
@@MRGF78 downforce isn't really very important for acceleration (in a straight line), mechanical grip is. Downforce comes in during acceleration in corners, whereas less mass is better. But less mass means less force exerted on the tires by gravity acting on the car forcing it to the ground, and that is why they try to compensate with aero downforce.
I remember when Ferrari made that record of 100 HP per liter around 1996 or so. They used 5 valves per cylinder & varied the opening times of the intake valves. (They opened one & then opened the other two afterwards). Honda got very close at 96 HP or so using aluminum pistons.
Honda made multiple variants of the B18c (1797cc) that made almost 110hp/L. Those specific variants came in cars around '96 or earlier. The B16a (1595cc) made 160hp in 1989.

koeniglicher the V6 turbo hybrid doesn't make that much power. In 1986, the BMW 1.5L inline 4 turbo make about 1300hp in qualify, about 900hp in race day. The impressive about the V6 is eficiency and reliability. Mercedes engine has 1:1 ratio between kinetic enegry and heat enegry. In the 80s, a engine usually last only 1 race, now it's 3 engines for 20 races; and it use alot less fuel. Lap time is reduce because of aerodynamic and tyre technology, not thing to do with power.
The most curious thing to me would be the valve spring system/package on those two engines. Very cool. I am glad designers are allowed or should I say, seeking to optimize the efficiency of their new engines vs what we gotten in the past. One thing that has always rubbed me wrong was the regulation of certain systems or components like a cat or egr instead of maybe say using a emissions target and allowing the engineers to design through efficiency, an engine that will do that without said parts. I just feel like regs like that box in our engineers. And I think placing a creative mind in a box is no good. Anyways I am stoked on these developments and would love to hear about the valve package especially the spring.
It's probably a cam directly over a valve bucket, directly over the valve stems, with an adjustment "puck" trapped between the bucket and the valve stem, like on an old Ferrari. Those set ups seem to be good up to at least 11,000 RPMs. Idk, about newer Ferraris - I don't turn wrenches anymore.
One of the other main differences between port and direct injection is that the piston crown in DI engines has a high swirl feature that creates a rich ball of air near the spark plug. The creates a locally knock resistant mixture for where the flame kernel begins, but keeps the rest of the cylinder lean for efficient and clean burning overall.
But then it would it need replacement of the piston return springs and the blinkerfluid would need to be able to withstand a lot more heat because of the muffler bearings
You know what really interests me that no one talks about? The fact that the Valkyrie engine has full lagging over the(inconel?) headers until the cats, but the GMA T.50 engine has no lagging and no ceramic coating(HWA V12 in the Huyara R)
I always had an extreme fascination of the early 90s era f1 cars with the tradition manual imagining how high they rev and how quick it takes to get there, and the drivers pushing the limit while having to take a hand off the wheel... then Gordon Murray makes this masterpiece of a car 🥲
A lot of folks think that rotaries rev very high. That’s not true. It’s combusting 3 times more than a piston engine for each single revolution. Therefore it makes it sound like it’s revving 3 times higher
I love hearing all the details on such highly efficient engines. it continually makes me try to ponder what factors I may be able to attempt to duplicate into one of my older V8 engines to try and make it more volumetrically efficient as well.
@@lucasvanhamburg4937 lol no, they don't. They produce around 200-210 hp/L.. if you remove the exhaust restrictions then it' could go 230 hp/L and technicaly it's still a stock motor but not stock straight from the factorry

"The engine is used as a structural member of the vehicle" That's a novel idea... Oh wait, that's been true of tractors for 80+ years. :D Just an engine and transmission rolling around on some great big tires!
Looks like I finally found the go cart engine I've been looking for since I took the Briggs&Stratton engine off mine in 1978. I've been waiting a long time for this.
Absolutely amazing! Now I'm going to return to my e46 diesel engine with its super narrow power and torque band and short rpm cut-off at about 4000rpm...
The most important parameter seems to be the rpm. It would be nice if you could explain what design aspects of these engines help them achieve these crazy speeds.
Short stroke limits the average piston speed, so the average con rod speed is limited to the material limits of con rods. That's really the main factor for specific power. Air flow optimisation also helps up to 10% more. Consider the Honda S2000 engine. It produces 125 hp/litre at 8400 rpm at 11.7:1 compression ratio. My engine does the same but at 7200 rpm. I haven't put headers on yet or ported the heads or changed the intake, but it will get to around 150 hp/litre. These engines are often developed on a 1 cylinder test engine. Get one cylinder right and multiply by the number of cylinders you want.
Aston Martin: Hey Cosworth do you have any good engine for my new car? Cosworth: yeah I might.. Cosworth: Walks back store.. Cosworth comes back.. Cosworth: Here.. This is an old F1 engine.
@@geogmz8277 It reminds me more of the old Can Am series. Remember those big bangers from the late 60's to early 70's. Those big block V8's were reaching 9 liters and 900+hp.
Direct Injected 4 stroke engines are a rather recent development - the past several years. There are also fewer intake valve deposits with port injection. Oil catch cans have become popular on DI engines to help control intake port, intake manifold, and intake valve deposits.
The thing is just two 6.2 ls crate engines gaffer taped together with four 81mm turbos strapped to it. I'm sure if they attached a big enough radiator and coolant pump, and ran enough boost, they could make somewhere near the claimed figure, possibly even without it exploding. That said, it would be completely uninteresting if it ever did work because it will never meet emissions regulations, it will weigh pretty much half a ton (literally) and I'm sure it would never do more than a few thousand miles before needing a complete rebuild. With all of that said, I still doubt it will ever make it out of that dyno room and into a car... It's a load of rubbish
I'm pretty certain it will one day be available to buy in Dubai since there is no such thing as emissions there. If it is a 12.4l engine making 5000hp it'll be a bit over 400hp/l which seems possible to me. However I think the car will need a complete engine rebuild every few hundred kilometers
It's just amazing people can make 19000rpm V10 engines in early 2000s for F1 cars, I can still remember the noise even they are gone for over a decade.
i think the reason why they use port injection is not only the cooling advantage. They also wanted to have a great gas/fuel mixture at high rpm. Quite impressive if you think that they can pass the crazy emission regulations with that thing :D
Valkyrie vs AMG Project 1, this is the battle I wanna see in the future, last time I was this excited was when "The Holy Trinity" of automobiles P1, 918 and LaFerrari were battling against each other.

Ok. After reading many comments I've decided what I'll say. First, I want to predict the compression ratio, I agree that I believe it will be low, I don't want to explain my math, but I'll bet the ratio is 9 to 1. Secondly, the formulas he's using really are simple. They may sound complex, but each formula overall has few steps, and few variables, with easy to discover permanents, allowing easy math. I think the elo formula is more complex than half the formulas he uses. Thirdly, last but not least, i love this channel! Keep posting the great content sir!
@Engineering Explained: Motorcycle engines, aspirated and with port injection, exists from years and have no problem to do more than 100kkm. In 2004 the Yamaha R1 was 140HP/l. Now they are around 200+HP/l (GSX-R 1000). On 4 cylinder engines made to be as lightweight as possible. Why this is so impressive when it's placed in a car engine is out of my comprehension.
R1s and other modern 4 Stoke bikes are for girls. Honda's NSR 500 2Stoke Race Bike made 200 hp and weighed in at 390 pounds. More hp then and R1 or GSXR or CBR. With half the cc's
the 600cc have even more ridiculous power/displacement. i just checked the suzuki has 125 hp, ~208 hp/l. (the gsxr 1000 doesn't output 200 hp. the gsx **RR** _does_ make 240-ish)
The Rotary of the car that won Le Mans 24h in 1992 - the Mazda 787B - makes ~270 hp/l n/a. 700 hp out of 2.6 l at 9,300 rpm. Rpm was limited - at 11,000 it couldve made 920 hp but for reliability they limited it.
People always ask how it is I got to know so much about how to work on cars and the engineering that goes into them despite not going to school or getting any formal training. I always tell them it's because of the internet like forums and such which is true but it's more specifically videos like these which are well made and enjoyable to watch as much as they are educational. Thank you for making a passion filled hobby of mine so fascinating and accessible
I was thinking, “They just made it really big, didn’t they?” *haha the saying goes “No replacement for displacement!”* Edit: clearly know that they didn’t just make it bigger Just joking about my initial thoughts before watching the video
This is brilliant engineering. Getting that type of power from a NA engine is unheard of, so lets not downplay their accomplishment by saying that they just made it bigger.
Whatever the shortest stroke is that still allows useful compression/combustion. There's probably a bike engine out there that gets close to answering this question. Shorter the stroke, higher the peak RPM. We don't tend to see engines with average piston speeds above about 25 m/s. Of course, a few exceptions, but consider 25-30 m/s to be the limit.
What limits the RPM speeds are the Piston max speeds inside the engine, he already did a video about this, there are these max speeds because the engine gets a lot of stress and vibration if it goes much further than this, which is not good, for example, the F1 car that does 20k RPM doesn't have a much faster Piston speed than a Honda S2000
I enjoy the comparisons to smaller engines using some basic heuristics. Drives the point home that this HP figure is actually NOT insane, just very well engineered to get the system to work in such a modular package. What's insane is that it's the same overall approach that AMD is using for their graphics and computational processors. Taking a small well functioning core, then scaling it not by size of system but by QUANTITY of systems. Much appreciated! Resubscribed after unfollowing a few years back ;)
360degrees in a circle, divided by 6 cylinders, means that when you have a firing event every 60 degrees they're evenly spaced and therefore most easily balanced. Also works on v12s. So I'm actually really confused why this cosworth v12 is 65 degrees between banks.
Can i suggest a video explaining how you tune an engine to run better on high octane fuel, companies like 5 star offer tunes based on octane selection and i am sure many of us are curious to how this is achieved, perhaps starting with an explanation of how low and high octane fuels affect combustion would be helpful..

The NA TWR Jaguar V12 in its 94 mm bore size in WEC was making 750 bhp back in the 80s at similar rpm , running pretty much the standard set up limiting RsPM ( Revs Per Minute ! ) but with 4 valves per cylinder and a rather mundane Zytek engine management system and amazing reliability . The engine with its 24000 ftlbs of torque resistance designed into the die cast block , head and sump could easily accept its use as a structural element of the car . But of course Aston Martin leaned heavily on the Jaguar engine when producing its first V12 as did Lister with its stroked 7 litre engine . I would have expected that engines should have improved dramatically in 30 years , but if the Jaguar V12 was improved to run a full gear train to run much higher revs ( the bottom end has no shortage of strength in bearing diameter and journal overlap) , we would know doubt see similar figures from a 60+ year old engine design .
It only makes sense... Since belts and chains stretch, it'll throw the timing off... and even by a millisecond at those rip'ems, could throw the whole system off by miles... just need herringbone gears to quiet them down and keep them centered... but they cost too... but worth it...
Think early honda v4 motorcycle engines. My 1991 VFR750. Had a really cool engine noise. Ran mine for 178,000 miles before selling. Engine never opened. Ran like a top!
If someone had told me back in the "futuristic" year 2000 that in 20 years we would have 1000 HP EV's and also 1000 HP ICE's I would have laughed until I died. Engineering today is just crazy! Of course I would also not have believed in laptops that have 24 cores on one die, and dGPU's that rival the best of the last generation...on a laptop! Computing power and engines and electric motors seem to keep going up and up and up....where is the end? Thanks for the video. GD, I learn so much from this channel.
To build a 1000 bhp v12 naturally aspirated engine alone is such a huge accomplishment, but to make it compliance with emission regulated and a street legal...wow, now that is a feat on it's own !
Without any forced induction? Probably no more than +10% horsepower peak. However it would have a flatter torque curve for sure. And be better with emissions.
zolikoff i actually think it would make more power,with freevalve, as you’d be able to use full cam timing at high rpm, this engine would be limited by cam timing to meet emissions.
Not exactly, the pistons and clearences in the heads are designed to be optimized for natural aspiration, slap a turbo on and you might bend a piston arm or something due to the excessive pressure being added by the turbo, if you essentially detuned the engine a bit by raising the compression ratio then yes but if you just stuck a turbo on or a supercharger, you’d most likely destroy the motor trying to make high HP numbers
@@dg-hughes whats funny is their BMEP is 14.3 which really isnt as good as it would seem as racing engines get 15-15.5. ferrari 458 is 15.1. they probably couldnt get it higher over the health of what is practically a race motor and maybe the 1000hp bug they seem to have set. to get that motor to run well with boost your talking about major changes to compression ratio, rods, pistons, piston ring clearance, cooling, intake, cams. that motor was engineered to be N/A only and after listening to how critical of weight that it was i bet that it really couldn't handle any more than what it is putting out.
@@dg-hughes Nobody ever talks about PSIA when discussing pressure, its always PSIG. You are smart enough to know that and not have to request specification to try and look smart
Love you videos' - but could you please please please address one question I've always had: "What is the limiting factor for engine RPMs?" In this video you're talking about 11k and 12k RPM in a street car, and I believe F1's used to go up to 16k+. What really gets me thinking about this is that at 12,000 RPM the total time the fuel has to burn/expand/work etc is only 1.25 ms. That doesn't seem like enough time to even ignite, let alone provide useful force. So, what is the upper limit, and would it be ignition time, or something else like inertial stress on the rods, etc. etc.??? I'd really love to hear your thoughts and get your insights. And THANKS for your series!!!
The limit on conventional valvetrain is actually the resonant frequencies of the valve springs. Valve springs start resonating, the valves stop closing. Oops. But the usual rev limit in a gasoline engine is caused by the intake not being able to provide enough air. In a diesel engine, the limit is fuel, which is why diesels can get into a runaway situation where they rev until something breaks.
So if I take that intake manifold, put it on my 6.5L diesel, then remove the rpm governor... It's already N/A and not direct injection, then according to my math it should go from 160HP to 1000 HP?
6.5l is direct inj bud. All oil burners are. That said if that small v 12 makes a 1000hp ur 6.5 should b more like 1500.00. And longer stroke means lots of torque at 11000rpm. Like 1000ftbls
I don't think there's anything concrete that has been stated that would tell us why. The airbox has carefully tuned resonance behaviour, but I think that's all. Who knows what they did.
You certainly do your homework! _And it shows_ I have moved away from the internal combustion engine, but love listening to great engineering! BTW Can't wait for my CYBRTRK to come to Oz in 2022! _l believe l will get a BIG kick out of YOUR breakdown of its engineering plus plus plus!_

German manufacturer are actually moving away from downsizing. BMW planned to introduce the 3 cylinder into a large portions of it’s models but they are now reversing the trend. Which does not mean that engines are becoming bigger but they will focus on 2L inline-4 cylinders and 3L inline 6-cylinders. Although I hope they keep the 4.4L V8 a bit longer as well.
As far as I remember Italians are still making V12s
pradhuman rehal you are right Ferrari and Lamborghini have V12 offerings
next generation, we don't sell oil changes, we sell engine changes
That's kinda last generation actually! Back in the day, lots of people just neglected oil changes and drove until they needed an engine rebuild, because that only costed like 100 bucks, maybe less lol!
Tbh that pretty much sums up any German engine designed in the last 10 years! They are so stupidly complex there is little point in trying to maintain them after a certain mileage, you just throw away the whole car!
At the same time though, how many of these cars reach 100,000km? The Mclaren F1 has been around for almost 30 years now and I doubt more than a handful of the production run have even reached 50,000KM let alone 100,000KM.

Can you do a vid on the “3rd spring” in racing cars. There to counter the stresses of downforce.
You mean the extra tender spring on the suspension? Nothing really special about it. It's just a spring with a rate tuned specifically to the behavior of the aero package to counter sporadic and rapid oscilations
Imagine the amount of engineering went into this beautiful piece of art just to sit on a bald millionaire’s garage.
What's wrong with that?
Imagine making a item that is art, a trophy, and an incredibly fun ride. Who cares about it's use, people love different aspects about the same item for different reasons.
The good part is that the money the bald rich guy spent is put back into the economy instead of his assets. More legal money in the economy is always a plus.
it means that the car doesnt need its overengineered engine if its purpose was to be a garage ornament
Just because you are passionate about cars doesn’t mean you are worthy of driving every master engineered vehicle.

Well a 4.0L V12 is a really small engine, I've never seen such small displacement for that amount of cylinders.
@@charlie_mk7.5 Early Ferraris were small displacement v12s. Formula one in the late 60s was 3 liters and many of those engines were 12s and the infamous BRM was 16 cylinders.
The Ferrari F50 had a 4.3 L V12 when it was released 😏
i have 2.0 inline 6
"Size does matter... for engines." That gave me a good laugh. 😂
I know it's an extremely unpopular opinion but I've never really liked Aston Martins much but I'm in love with the Valkyrie and it's engine. Amazing looking and impressive engineering.
Amazing to think that the suspension supports downforce greater than the payload capacity of many pick ups.
But... do they really need that much down force to keep the traction needed to accelerate??? Or did they over engineer that factor??? They could lighten the weight of the engine a lil more if not...
MRGF78 I think they did it so the car would be able to corner quickly because it would be used more on a track
@@MRGF78 downforce isn't really very important for acceleration (in a straight line), mechanical grip is. Downforce comes in during acceleration in corners, whereas less mass is better. But less mass means less force exerted on the tires by gravity acting on the car forcing it to the ground, and that is why they try to compensate with aero downforce.
@@MRGF78 "Over engineer" wow, talk about Dunning Kruger right here. Do you honestly think you can outsmart Adrian Newey and Cosworth?
I remember when Ferrari made that record of 100 HP per liter around 1996 or so. They used 5 valves per cylinder & varied the opening times of the intake valves. (They opened one & then opened the other two afterwards). Honda got very close at 96 HP or so using aluminum pistons.
Honda made multiple variants of the B18c (1797cc) that made almost 110hp/L. Those specific variants came in cars around '96 or earlier. The B16a (1595cc) made 160hp in 1989.
1999 S2000 made 125bhp per liter. It held the record until the Ferrari 458 was launched

"Bring back the F***ing V12s"

70s f1 was the best cause they had v12s but nowadays we have teeny tiny turbo v6 engines
@@romirsarangi4341 We have "teeny tiny 1.6 turbo v6 engines in hybrid configuration" that make way more power than those 70s V12s - and quicker lap times. Those 70s had V12s that had a 3.0 Liter naturally aspirated or 1.5 Liter turbo limit in displacement. And no electric support whatsoever.
The car guy you’re actually wrong the 50’s 60’s 70’s 80’s 90’s 2000’s 2010’s are the best in F1. Cuz all F1 eras are amazing. 1952 brm 1.5L V16 supercharged making 700hp. The 60’s has Jim Clark’s dominance along with Jackie Stewart staring the drivers safety regulations. The 70’s has ground effect, the only American F1 champion, the lauda and hunt show, 3 wheeler...the 80’s had the mclaren dominance and the turbo era began and ended....the 90’s had the most advanced F1 car ever built in the fw14b, the start of Michael Schumachers amazing career and senna’s demise (rip legend) the 2000’s had michaels dominance followed by Alonso taking the thrown, than had it snatched by a rookie black kid from stephenage, the spy gate, the crash gate...the 2010’s had redbull and vettels dominance and the start of mercedes dominance....what I’m getting at is that all of F1 is amazing just wish you guys would see the bigger picture. Jim Clark won a race by 5 mins in the 60’s...with a far superior car but you guys ridicule and devalue Lewis? Just please enjoy greatness while you’re watching it.
@@fastballfilms4214 I agree
koeniglicher the V6 turbo hybrid doesn't make that much power. In 1986, the BMW 1.5L inline 4 turbo make about 1300hp in qualify, about 900hp in race day. The impressive about the V6 is eficiency and reliability. Mercedes engine has 1:1 ratio between kinetic enegry and heat enegry. In the 80s, a engine usually last only 1 race, now it's 3 engines for 20 races; and it use alot less fuel. Lap time is reduce because of aerodynamic and tyre technology, not thing to do with power.
The most curious thing to me would be the valve spring system/package on those two engines. Very cool. I am glad designers are allowed or should I say, seeking to optimize the efficiency of their new engines vs what we gotten in the past. One thing that has always rubbed me wrong was the regulation of certain systems or components like a cat or egr instead of maybe say using a emissions target and allowing the engineers to design through efficiency, an engine that will do that without said parts. I just feel like regs like that box in our engineers. And I think placing a creative mind in a box is no good. Anyways I am stoked on these developments and would love to hear about the valve package especially the spring.
It's probably a cam directly over a valve bucket, directly over the valve stems, with an adjustment "puck" trapped between the bucket and the valve stem, like on an old Ferrari. Those set ups seem to be good up to at least 11,000 RPMs. Idk, about newer Ferraris - I don't turn wrenches anymore.
One of the other main differences between port and direct injection is that the piston crown in DI engines has a high swirl feature that creates a rich ball of air near the spark plug. The creates a locally knock resistant mixture for where the flame kernel begins, but keeps the rest of the cylinder lean for efficient and clean burning overall.
I'm so glad you specified "For engines", I almost lost hope for a second.
Imagine if someone put a NOS sticker on the car.....you would have something that is 1500 HP naturally aspirated.
It also has kers so you could use a "LOLGAS" magnet or similar to bump it to 2000hp
Don't forget the flames on the side.
Imagine if someone added water instead of petrol to the fuel tank!
Nos is great but its really cracking things like x10 faster
But then it would it need replacement of the piston return springs and the blinkerfluid would need to be able to withstand a lot more heat because of the muffler bearings
Great Video!
You need to look carefully of some of the newest 1 liter N/A Sportbikes. 153.8 HP per liter is so 10 years ago. Seeing 200+ now.

Absolutely amazing! Now I'm going to return to my e46 diesel engine with its super narrow power and torque band and short rpm cut-off at about 4000rpm...
The most important parameter seems to be the rpm. It would be nice if you could explain what design aspects of these engines help them achieve these crazy speeds.
Short stroke limits the average piston speed, so the average con rod speed is limited to the material limits of con rods. That's really the main factor for specific power. Air flow optimisation also helps up to 10% more. Consider the Honda S2000 engine. It produces 125 hp/litre at 8400 rpm at 11.7:1 compression ratio. My engine does the same but at 7200 rpm. I haven't put headers on yet or ported the heads or changed the intake, but it will get to around 150 hp/litre. These engines are often developed on a 1 cylinder test engine. Get one cylinder right and multiply by the number of cylinders you want.

Direct Injected 4 stroke engines are a rather recent development - the past several years. There are also fewer intake valve deposits with port injection. Oil catch cans have become popular on DI engines to help control intake port, intake manifold, and intake valve deposits.
That’s pretty sweet. But my Prius engine makes somewhere in the neighborhood of 85hp, which is much more reasonable.
You're right, totally usable!

Maybe you should debunk/confirm the Devel sixteen engine claiming to make 5,000 hp.
Stewart Morley let me do that for you right now! It's fake.
You really need help with that?
The thing is just two 6.2 ls crate engines gaffer taped together with four 81mm turbos strapped to it. I'm sure if they attached a big enough radiator and coolant pump, and ran enough boost, they could make somewhere near the claimed figure, possibly even without it exploding. That said, it would be completely uninteresting if it ever did work because it will never meet emissions regulations, it will weigh pretty much half a ton (literally) and I'm sure it would never do more than a few thousand miles before needing a complete rebuild. With all of that said, I still doubt it will ever make it out of that dyno room and into a car... It's a load of rubbish
I'm pretty certain it will one day be available to buy in Dubai since there is no such thing as emissions there. If it is a 12.4l engine making 5000hp it'll be a bit over 400hp/l which seems possible to me. However I think the car will need a complete engine rebuild every few hundred kilometers
the engine is real but they will never put it in the car
It's just amazing people can make 19000rpm V10 engines in early 2000s for F1 cars, I can still remember the noise even they are gone for over a decade.
No valve springs right?
i think the reason why they use port injection is not only the cooling advantage. They also wanted to have a great gas/fuel mixture at high rpm.
Quite impressive if you think that they can pass the crazy emission regulations with that thing :D
I think it has to do with fuel particles falling out of suspension at certain intake charge velocities and sticking to the cylinder walls.

@Engineering Explained: Motorcycle engines, aspirated and with port injection, exists from years and have no problem to do more than 100kkm. In 2004 the Yamaha R1 was 140HP/l.

R1s and other modern 4 Stoke bikes are for girls. Honda's NSR 500 2Stoke Race Bike made 200 hp and weighed in at 390 pounds. More hp then and R1 or GSXR or CBR. With half the cc's

The second engine he mentions is only 3.9 litres.
I love how Jason actually uses math to do these demonstrations! If you're going to explain something explain all the way and run the numbers.
i would like to ask, what would be the highest theoretical rpm of an ice engine without any limitation, like nothing would break even at insane rpms
I heard that the Ferrari F1 NA engine at its max revved up to 21000 rpm.
Whatever the shortest stroke is that still allows useful compression/combustion. There's probably a bike engine out there that gets close to answering this question. Shorter the stroke, higher the peak RPM. We don't tend to see engines with average piston speeds above about 25 m/s. Of course, a few exceptions, but consider 25-30 m/s to be the limit.
What limits the RPM speeds are the Piston max speeds inside the engine, he already did a video about this, there are these max speeds because the engine gets a lot of stress and vibration if it goes much further than this, which is not good, for example, the F1 car that does 20k RPM doesn't have a much faster Piston speed than a Honda S2000
One thing that helps a car revving higher is the smaller stroke, those F1 cars are 3.0 V10 engines with pretty small stroke associated to the engine
I've heard about a civic that money shifted and reved up to 22k
I enjoy the comparisons to smaller engines using some basic heuristics. Drives the point home that this HP figure is actually NOT insane, just very well engineered to get the system to work in such a modular package.
What's insane is that it's the same overall approach that AMD is using for their graphics and computational processors. Taking a small well functioning core, then scaling it not by size of system but by QUANTITY of systems.
Much appreciated! Resubscribed after unfollowing a few years back ;)
About time really, bikes have been revving around this figure for decades
Please tell us why a V6 with 60º angle is the perfect engine geometry 😉
It's total Dimensions come close to a qube, so its great for the amout of space a certain amount of displacement needs.
360degrees in a circle, divided by 6 cylinders, means that when you have a firing event every 60 degrees they're evenly spaced and therefore most easily balanced. Also works on v12s.
So I'm actually really confused why this cosworth v12 is 65 degrees between banks.

Would love to have seen the cadillac 16 come to production, absolutely massive V16 with 1000HP/1000tq NA. glad SOMEONE is finally doing it
The NA TWR Jaguar V12 in its 94 mm bore size in WEC was making 750 bhp back in the 80s at similar rpm , running pretty much the standard set up limiting RsPM ( Revs Per Minute ! ) but with 4 valves per cylinder and a rather mundane Zytek engine management system and amazing reliability . The engine with its 24000 ftlbs of torque resistance designed into the die cast block , head and sump could easily accept its use as a structural element of the car . But of course Aston Martin leaned heavily on the Jaguar engine when producing its first V12 as did Lister with its stroked 7 litre engine . I would have expected that engines should have improved dramatically in 30 years , but if the Jaguar V12 was improved to run a full gear train to run much higher revs ( the bottom end has no shortage of strength in bearing diameter and journal overlap) , we would know doubt see similar figures from a 60+ year old engine design .

I'm liking the idea of gear timing rather than belt or chain!!
It only makes sense...
Since belts and chains stretch, it'll throw the timing off... and even by a millisecond at those rip'ems, could throw the whole system off by miles... just need herringbone gears to quiet them down and keep them centered... but they cost too... but worth it...

Sure, boost is nice. But if you boost a larger motor......

If someone had told me back in the "futuristic" year 2000 that in 20 years we would have 1000 HP EV's and also 1000 HP ICE's I would have laughed until I died. Engineering today is just crazy! Of course I would also not have believed in laptops that have 24 cores on one die, and dGPU's that rival the best of the last generation...on a laptop! Computing power and engines and electric motors seem to keep going up and up and up....where is the end? Thanks for the video. GD, I learn so much from this channel.
To build a 1000 bhp v12 naturally aspirated engine alone is such a huge accomplishment, but to make it compliance with emission regulated and a street legal...wow, now that is a feat on it's own !
What do you think would happen if this engine was fitted with Freevaulve technology 🤔
Without any forced induction? Probably no more than +10% horsepower peak. However it would have a flatter torque curve for sure. And be better with emissions.
zolikoff i actually think it would make more power,with freevalve, as you’d be able to use full cam timing at high rpm, this engine would be limited by cam timing to meet emissions.
Freevalve is overrated...
That's such a cool idea that would be awesome to see but would never happen.
Unless Koenigsegg make an NA V12 free valve engine
@@nik7bkh965 is being able to change lift and duration however much you want within reason overrated?
Ok so now I need to find the TH-camr that will make a video on how they Twin Turbo and Nitrous this thing a year from now. 🍿🍿🍿
So what you’re saying is this thing could make like 2000 hp at one bar...
Not exactly, the pistons and clearences in the heads are designed to be optimized for natural aspiration, slap a turbo on and you might bend a piston arm or something due to the excessive pressure being added by the turbo, if you essentially detuned the engine a bit by raising the compression ratio then yes but if you just stuck a turbo on or a supercharger, you’d most likely destroy the motor trying to make high HP numbers
Im pretty sure having boost at rpm with An engine that is already stretched out would send Parts flying everywhere
It makes 1,000hp (746kW) at 1 bar which is normal sea-level atmospheric pressure. Do you mean 2 bar?
@@dg-hughes whats funny is their BMEP is 14.3 which really isnt as good as it would seem as racing engines get 15-15.5. ferrari 458 is 15.1. they probably couldnt get it higher over the health of what is practically a race motor and maybe the 1000hp bug they seem to have set. to get that motor to run well with boost your talking about major changes to compression ratio, rods, pistons, piston ring clearance, cooling, intake, cams. that motor was engineered to be N/A only and after listening to how critical of weight that it was i bet that it really couldn't handle any more than what it is putting out.
@@dg-hughes Nobody ever talks about PSIA when discussing pressure, its always PSIG. You are smart enough to know that and not have to request specification to try and look smart
Wowsers.That's one gutsy radiator, that can shed more than 2,000hp to the surrounding air!
Love you videos' - but could you please please please address one question I've always had:
"What is the limiting factor for engine RPMs?"
In this video you're talking about 11k and 12k RPM in a street car, and I believe F1's used to go up to 16k+. What really gets me thinking about this is that at 12,000 RPM the total time the fuel has to burn/expand/work etc is only 1.25 ms. That doesn't seem like enough time to even ignite, let alone provide useful force.
So, what is the upper limit, and would it be ignition time, or something else like inertial stress on the rods, etc. etc.???
I'd really love to hear your thoughts and get your insights.
And THANKS for your series!!!
The limit on conventional valvetrain is actually the resonant frequencies of the valve springs. Valve springs start resonating, the valves stop closing. Oops.
But the usual rev limit in a gasoline engine is caused by the intake not being able to provide enough air.
In a diesel engine, the limit is fuel, which is why diesels can get into a runaway situation where they rev until something breaks.
Every time when I saw whiteboard behind you, I say "Ah, here we go again."
So if I take that intake manifold, put it on my 6.5L diesel, then remove the rpm governor... It's already N/A and not direct injection, then according to my math it should go from 160HP to 1000 HP?
Your diesel has a much longer stroke. It would never rev that high
@@bhill7807 torque tho!!!!
6.5l is direct inj bud. All oil burners are. That said if that small v 12 makes a 1000hp ur 6.5 should b more like 1500.00. And longer stroke means lots of torque at 11000rpm. Like 1000ftbls
B HILL clearly you've never seen a runaway diesel
You didn’t talk about how they got the intake and value train to work well up to 11k rpm?
I don't think there's anything concrete that has been stated that would tell us why. The airbox has carefully tuned resonance behaviour, but I think that's all. Who knows what they did.
The same way Honda gets their motorcycle valvetrain to run at 12k rpm?
Huge fan of your broad knowledge and your channel. I learn alot from you.
You certainly do your homework!
_And it shows_
I have moved away from the internal combustion engine, but love listening to great engineering!
BTW Can't wait for my CYBRTRK to come to Oz in 2022!
_l believe l will get a BIG kick out of YOUR breakdown of its engineering plus plus plus!_

Is that kind of losing traction? LOL..
