@@Squilliam-Fancysonnot really... The 18k limit was introduced in 2009 i believe... In 2006 when the regulament allowed the V8 engines, some teams were touching the 20k rpm mark, most of Them topped at around 19.5k
According to a friend of mine, who was seriously into engine development, the problem is no longer with the mechanical side of the engine. The problem is getting decent combusion at +20,000 rpm. After all, the entire power stroke takes place in 1.5 milliseconds.
@r3dph0n3 yup. all the pistons and such are super light, and to my understanding these engines don't use a flywheel. so they've got to have high idle revs in order to stay running.
20,000 rpm = 333Hz. However, if you compare the engine sound @ 20krpm to a tone signal generator, you find the predominant engine sound is at 666Hz, or twice the engine crankshaft rotational frequency. Why is this the predominant engine sound? Cylinder firing should be 4 times per rotation as it is a V8 completing 8 combustion cycles every 2 revs at it is a 4 stroke engine, so you would expect a 1333Hz engine sound from cylinder events... ??
+GoDownOnMyBullet Listening to it again it sounds like the highest pitch is probably 1333 Hz. There are also tones a few octaves below it which makes it hard to discern the highest pitch.
@gblpst81 The secret to those high revs is called PNEUMATIC VALVEGEAR.Ordinary springs can be taken to around 12,000rpm, above that those pneumatic valves of F1 engines make it possible to rev up to 18,0000-20,000 rpms Renault pioneered these pneumatic valves in 1986,which meant that for a while they had around 1300hp from their 1,5 litre turbo V6 in qualifying trim.For races they ran around 900hp Pneumatic valves are expensive and require a lot of tuning, hence they don't appear in roadcars
will be interesting to see whether cosworth can produce a reliable V8 engine next year. This and all the new chassis' will be sweet. Can't wait. Bring on 2010!!!
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.
The minimum weight permissible is 600kg including the driver, fluids and on-board cameras. However, all F1 cars weigh significantly less than this (some as little as 440kg) so teams add ballast to the cars to bring them up to the minimum legal weight. The advantage of using ballast is that it can be placed anywhere in the car to provide ideal weight distribution.
@sirlonghair In 2005, the last year with V10 engines, the BMW engine produces some 940hp, and rumors have it the Honda V10 had close to 950hp. From a 3,0litre V10 that is impressive to say the least. F1 engines haven't been similar to those designed for roadcars since the mid 60's, and the last roadcar based engine was the BMW straight 4, used in the 80's. In 2013 the new rules WILL mean F1 engines CAN be used as modern, frugal and powerful units for roadcars. Fuel efficiency is the keyword
@xhikomarux thats right. Its the box/bowl looking thing under the motor where the sump plug is that you take out of a normal engine to drain the oil. 20000 RPM is awesome, but spend enough money in development and its achievable. Huge amounts of money do wonderful things to an engine!
@rminb010204 actually they idle much lower than that, about 2,000 RPM or so. But they have absolutely no power down there, if you listen to the start of a race the clutches don't bang in until about 10 grand or so off the line, and if you listen onboard coming out of a hairpin you can hear the engine struggle a bit until the RPMs get up. Still, these engines are amazing and they sound beautiful.
Pushrod engines don't rev very high and this is the reason they are never used in high tech motorracing where outright power for a maximum amount of displacement is used. The only real benefit they have is that they are easy and cheap to manafacture, hence keeping the price down.
It was limited, to allow valve bounce would invite catastrophic failure. It doesn't throw a rod because the stroke is very short and the pistons are very light so the actual piston accelerations are not much different from a high end drag motor only they have to last a race rather than a few minutes.
@dano253 In fact the fuel does never combust completely, even on a normal car. The combustion is a normal chemical reaction, and I think it's impossible to have 166 COMPLETE reactions per second (that's what JGMagoo said below). That's what happens but it's quite normal that they are incomplete.
it's not simular, they actually drive with 18.000 in 7th gear in 2010 @ topspeed for the needed amount of time, until the next brake action. i think the powerband is simular to old times, in the 20.000+ range, but cut off @ 18.000. i think there is incredible good algorythm in the 'strandart' ECU to prevent things like a street car engine @ max rmp, the engine starts getting wild in the 6k rpm range.
i thought you were wrong, but i did the math and your right,i did the math for a 3" and a 4" stroke and 3" has 83 ft per sec while the 4" stroke has 111 ft per sec, i realized the crankshaft makes all the difference since it has a longer stroke on a v8, the journals for the rods are further from the center making the movement from TDC the BDC much faster than an engine with shorter stroke at the same rpm.
I was impressed with the 9,000 RPM idle.
me too
haha I came to the comments section expecting to see this.
Same
My diesel redlines at 4400rpm
Yep, the Nearly 9500 RPM idle was Def in its own League!
I like how this makes 9000 revolutions seem mellow
Yes in deed! 9000 rpm sounded like an idle. :)
Arend Nydam lol it sounded like 4K rpm lol
I love how it idles at over 9000 rpm (I'm not making an "over 9000" joke)
Beautiful engine.
IT'S OVER 9000!!!!!!!!!!!!!!!!!!!!!!!!!
You didn't but I did
@@umakariharu8035 holy shit that joke is that old
Right 9000 was so non eventful.
Its not actually idling at 9000 rpm, they just left the throttle a little bit open
at this rpm the pistons are moving up and down over 300 times a second, that is insane.
more than20 metres / per second
If Formula 1 was made into a horror movie, this would be the music to the scariest part...
I like the sound of it hitting 20,002 You can tell it sounds maxed out right there!
It sounds like , it want's to die. Actually the F1 V8s never were build for rmps above 18k

Yes, that's why they need the smallest combustion chamber
Sounds like a chromatic scale
COSWORTHCA2006 FROM F1 CTDP RACING SEASON '06
Am I the only one who loved the sounds the best when they used to run 12-15k rpm 3.5's???
+Brandon Ryan yeah sounds like a 787 4 rotor
Totally agree! Those were the best sounding of all the F1 engines.
Wow serious that is crazy to think what holds them together other than some serious balancing act
This comment didn't age well 😅
20k rpm... wow. Amazing tech.
That's some serious balancing and strengthening there !!
I want it :P
Imagine a production car that could reach 20k rpm
Why? Cosworthit
Capri Driver bruh😂😂😂
Why the hell not. 20,000rpm v8 who has one?!? Why the hell not?
Levi Jones he was making a play on the name Cosworth. “Cosworthit” ......cause worth it
@r3dph0n3 yup. all the pistons and such are super light, and to my understanding these engines don't use a flywheel. so they've got to have high idle revs in order to stay running.
I heard they also use no crankshaft counterweights - engine outpaces any crank vibrations!

Could this be because the frequency heard is from each cylinder bank separately (due to separate exhaust pipes) is half the firing frequency?
+GoDownOnMyBullet Listening to it again it sounds like the highest pitch is probably 1333 Hz. There are also tones a few octaves below it which makes it hard to discern the highest pitch.
Mandela effect
Put this in my civic
Calm at 9,000 rpm, a beast at 20,000rpm.
Welcome BACK to F-1 Cosworth!! Lets hope that they get rid of the rev limiter. Love to see 22000rpm 's or more !
wow that is incredible!
i cant even imagine how loud that would be in person
Imagine what it must look like on the inside of that motor with all of those parts moving. That is just totallyt insane!!!
oh man, after that 9000rpm sounded like highway cruising! amazing engines
wow thats just amazing!
So that's the unit that powers my Dentist drills.
i think the pistons are vibrating with that kind of amazing output
SICK!
and you can float valves at 6k in a 318.. lmao wow this is awesome
variable valve timeing is awesome technology
that was sick!::O
Anyone else get this in their recommended after Rob's new video?
6 seconds, 1/10 of a minute, 2,000 rotations, 1/10th of 20,000
love the 9,000 rpm idle
i miss the v12's of the 90's
plus the f1 cars looked sweet as!
thats sooo sick
PROPER F1 ENGINE AND SOUND 😈 🔝
engineering at it's finest
That's insane!!!
Wow, I've been Cosworth fan since the 80s but this thing just sings compared to the older ones.
The engine blocks also tend to be smaller, lighter, and with a bit lower center of gravity with pushrod engines.
True
amasing! 20krpm, i can't imagine
Nothing can beat my nitro rc 2 stroke engines. Those rev from 35,000rpm to even over 40,000rpm
oh thanks i glanced at the description, just didnt stare lol

thank you at least someone not a complete jerk when it comes to motors.
the exhaust manifold will be glowing RED hot!!

chilling at 9,000 haha love it!
@dtiydr I think they do that to check vibrations at different engine speeds, or to check consistency of the engine speeds.
The minimum weight permissible is 600kg including the driver, fluids and on-board cameras. However, all F1 cars weigh significantly less than this (some as little as 440kg) so teams add ballast to the cars to bring them up to the minimum legal weight. The advantage of using ballast is that it can be placed anywhere in the car to provide ideal weight distribution.
Ford/Cosworth does it again.
I like Ford. But in the V8 era Ford is no longer in partnership with Cosworth. That's why it doesn't anymore sport some Ford badges.
it doesnt even sound stressed at 20k whaaatt🔥
My van (diesel) redlines at 4500 RPM. The plane I fly redlines at 2700 RPM. :-)
I've never heard 9k rpm sound so civilized
ive never heard 9000rpm sound so civilized
The valve train is still cam activated, except it uses compressed gas in place of a coil style valve spring.
@snipinggod29 yes it is actually a pnumatic systlem as springs would not be able to controle a valve at that speed without failing.
Balanced and then some!
ya know shit! love to find the tech that disigned those

You predicted the Mercedes AMG One
9000 was chilling
nice!
That engines Idle is OVER 9000!
(Barely but it is) :P
ITS OVER 9000
sounds like the tornado siren in town i live in
I love the sound of a muscle, but I am also a sucker for the sound of an F1 motor.
to those whom say that the idle is 9000 rpm, you are wrong the engine was in cooldown mode, the actual idle is 4000-6000 rpm
this is not the usual cosworth engine, it;s the one from the f1

This reminded me of my last trip to the dentist..
@strange6 they are accualy in the 800 - 900 hp range the torque curve is almost completely flat and holds out past the rule mandated rev limit.
@rminb010204 actually they idle much lower than that, about 2,000 RPM or so.

I like how it idles at 9k rpm
dear god, the imagery D:
A modern F1 engine like this uses pneumatic valves to avoid tyhe problem of springs rebounding.
Springs are pneumatically actuated, like a shock absorber. Regular springs turn into jello at over 15,000 rpm.
I bet the exhaust manifold was glowing after that.
thanks that helps
short stroke, big bore, triple coil valve springs, very good timing, ignition, ultra lightweight valvetrain
It was limited, to allow valve bounce would invite catastrophic failure.
