@lHustonProductionsl There's a reason for the Bugatti powerplant figures. It could possibly make 2000 BHP, but there will be too much lag, too much heat, very unrealiable (like those modded Nissan GTRs) and you'd probably have to refuel the car every five yards. So yeah, they made it perfect, not outright power which is almost impossible to put down on the road.
@lHustonProductionsl You should think again about "V8s that drive better". No American car can go around a corner faster than Euro cars. But on the other hand, the new BMW M5 is very fast, with a twin turbo V8. And Bugatti Veyron is not pathetic. They made the engine like that, so that it wouldn't break down... Let's see your single turbo V8 do 1000hp for 10, 20, 30 maybe even 40 years. Good luck with that.
Usually these engine shows real potenical in light cars like Radicals, Westfields, Caterhams, MK Indy, Locost, Ariel Atom, and many others. Small displacement engine produce less torque than bigger (that's simple math).
Well, V6 V8 and other V10/12 sounds much better and it's more balanced, more engineered. Many I4 makes power at over 6000rpm, but turbocharged I4 can make lots of torque at low rpm and max power as well. Every engine has a purpose. Heavy cars need torque.
@lHustonProductionsl im pretty sure all cars with engines have the sound of an engine. lmao No need to be racist. Civics are more like 2,400 pounds buddy. You having 2 more cylinders and the same hp is pretty sad even for stock.
@lHustonProductionsl The dummy is still you. hahah My comment was about turbos not only being for ricers not engines in general. Stupid, you just contradicted yourself in that comment. The bugatti still has about the same displacement as those v8's w/ turbo. I like all cars <3 ps : my buddy's non turbo 4cyl civic could probably smoke your pos v6 grand prix. lol American rice
@prolesorwell This was the first engine to hit 20,000rpm + at the time. Mercedes was a long way behind back then. These days, the V8's are restricted to 18,000 rpm.
Its funny that when you can get to 20,000 rpm, the engine sounds mild at 10,000 rpm. My engine sounds like its about to spit a ring out the side when its at 7k rpm lol
To reach 20000 rpm it's not just the short stroke distance that is the reason. One other reason is I think it has a flat plane crank which is used instead of a cross plane crank which has counterweights on the crank shaft. Hence the reason for the sound being very different to a v8 in an average family car. (even at lower revs)
The bore on the new Ferrari engine is 98mm. I did some math and the stroke is somewhere between 37mm and 38mm. I would guess the Cosworth is around the same. That's one of the many reasons these engines can rev so high.
Cosworth are WITHOUT a doubt THE BEST engine builders/tuners in the world, ever. They're parternership with Ford of europe [Ford RS] meant that the ford cosworth patnership dominated all forms of motorsport, BTCC, Rally, autocross, F1 and so so much more. Most of these types of motosport had to have rules changed because the cars were TOO good! Ford Cosworth FOREVER... because they ARE the best, it does not matter what other people think. They think wrong. Cosworth --- cos its worth it! Period
i am in a huge fight with my class mates at Lincoln Tech about this. can someone please tell me what kind of block this is?????????????????????????????
@sk8hard4life91 its a COSWORTH block, They make thier own engines. They have been putting their engines in everything from purpose built racecars to old datsun 240's to even the ford escort at one time. they are the company car manufactures turn to when they want a high performance engine and dont want to do the R&D themselves. There is much more info available at cosworth.com and also a good bit on wiki. All in all one of the best engine manufacturers there has ever been.
@Blootster Whoa, calm down. It was a question, a question means I didn't know the answer at the time. But, I gave them a call and it turns out they can, unfortunately ScORTED was correct, they are well above my price range, perhaps in the future that will change. So even though it was a question, the answer signifies it wasn't a dumb question, which makes me wonder, did you just find some random person on YouTube and call them "fucking retarded" to try and start a fight or something?
hahahahahhaa...yes they are very special motors. but think of a motor that doesnt have traditional heads. think an experimental motor that would be the exact reverse of a traditional vw horizontally opposed 4cyl motor?. the cylinders meet head to head resulting in an 8cyl motor my buddy and i have been working on. so far so good and no pics will be posted yet. valves and direct drive system is all hydraulic. replacing the heavy traditional transmission thanks to a top machine shop. 500+hp ;)
I have been in this room, got to see them testing the new ca2010. Also got to see the internals of it in the assembly room. I dont know how this video got out, they were very strict about filming
This is a Formula 1 V8. 2400cc. Nothing to do with regular production big fat V8. Pneumatic valves, lots of exotic alloys, special fuel.
At this spec, the engine can only last 1 race. Less than 1000km.
Now, for savings matters, they are not allowed to go over 18.000 rpm. And F1 Teams are only allowed to use 8 engines per car for the complete season (19 races).
In '89 I watched my bro-in-law dyno run up a Cosworth V8 Indy Car motor belonging to Kraco. He forgot to turn the water on, and in 10 secs, it was a 'spare'. Don't tell anyone ok, 'cos' we don't mention it.
this in not a big v8, this may be a max of about 2000cc (2Lt), a large 6 Lt v8 could not rev this hard, it would just fly to pieces. this engine most pobably runs in a f1 kart.
Yeah if Cosworth wants back into F1 and stay there they need to make engines that will go the race distance. They use to be one of the greats in F1 but only the teams that cant afford customer engines get them now
well at least that one didn't blow up, probably the only one not to, the few F1 teams that ran cosworth F1 engines in 2006 I think they all suffered engine failures throughout the year
they kept bragging Cosworth F1 engines are the only ones in the F1 paddock that rev to 20K RPM, lol meanwhile they became the laughing stock of engines, and eventually being told their engines would no longer be required, and now they are coming back for 2010 let the failures begin!! who wants to bet?
holy shit. i want to see the internal parts to this motor. there has to be something special bout it to get to go that high. maybe rotary valves or a very sophisticated overhead cam system. i dont know much about those motors but if someone could it explain the details to me that'd be great. ive seen an engine hit 38,000 rpm but that was the nitro powered 2 stroke in my RC car that is only .12 cubic inches. but for a big V8 20,000 rpm even 10,000 rpm is amazing
that makes sense but what actuates the pneumatic valves? air pressure from a small compressor? also do the pneumatics move the valves both ways? cuz i cant picture a valve spring working that fast.
Pneumatically actuated valves, and a lot of titanium. It' is only 2.4L displacement, so the bore and stroke are very small, combined with extremely light parts....
@Turbojeep23 they have pneumatic valve springs instead of metallic ones, and the valves are probably extremely light. and i would guess this is a 2400cc formula one powerplant, nowadays the rpm is limited to 18k
@Turbojeep23 i guess this is one of their recent f1 engines,2.4ltr v8, if it is, one of the many clever things that enable them to rev that high, firstly f1 engines, now spread to other formula, motogp etc, are electronically fire valves, springs just don't work at these speeds. but there are many other clever things in those engines, bare in mind that piston heads on f1 engines, when at about 18k rpm, are, at each end of their stroke, are under a load of 50,000g. that's a lot in anyone's book.
@Turbojeep23 ive got a honda cbr 250 and it will rev to 20,000 rpm all day .i realize that it is a lot smaller then this v8 but just thought id let u no that there are actually road going veichles that will rev that high
@Turbojeep23 i watched a program about the williams f1 team to get an engine to rev you have to make the parts as light as possible. the pistons are real tiny and everything is a special titanium alloy. the more revs u get the more fuel and air passes through the engine hence why you can get 1000hp plus from a 3 litre na engine.
@mrdangerous667 no so much as the pistons are "real tiny" as they have a very short stroke. This lowers the overall speed they come up to in order to move up in down in a given revolution of the motor. The shorter the stroke the lower the piston stroke speed allowing for higher RPM.
@fcguy7 by tiny i meant they are really short nt small diameter. the distance from the crown to the base is less than the diameter so it and the conrods etc weigh next to nothing because of the materials they are made from. also the tolerances are so small with the parts the engine is actually seized when its cold you have to heat the water and oil system up first so its such a tight fit in the bore that you get maximum compression.
@mrdangerous667 The size of the piston, crown to base, has little relative effect other than weight ... the crank determines stroke. Again, tiny pistons ... diameter or height ... however you meant it ...
@Turbojeep23 They are not very big at all, a fair few jap i-4 bikes would have more displacement per cylinder then one of these f1 engines, dont quote me on this tho as i havnt really looked at much info on these motors.. 10k is amazing but an aussie guy has made a 4l 1uz-fe (quadcam toyota v8) get around 9,600rpm. And these are mass produced engines.. you can buy a v8 made with 2 hyabusa 1.35l heads, ranging from 400-650hp with different cam setups..
@Turbojeep23 ive heard something about the valves being pneumatically powered after a certain rpm to prevent valve float but thats about it. also keep in mind that the pistons dont move up and down that much, they almost vibrate :P
@Turbojeep23 That's the thing, It's not a big V8. It's just a 2.4 which helps alot with the rpms. But still, the engine must have something special like you said.
thats sick man...my stang can barely hit 7,000..lol....imagine 20,000...owned...those f1 engines are sick....what kind of valve train do they have you know, valve springs.etc...without preventing valve float...
This engine doenst come close the the price of you house. My Pinto engine (2liter) does 8000rpm and that cost alot of my money to make it. Spend +-5000euros. And 5000euros compared to that engine and shit.
@Scotracer and trying to figure out how to make them work, and work right is like shooting your self in the foot and trying to fill the hole with a second bullet.
@Scotracer if that! usually valve float will will occur much lower depending on the engine. then it starts backfiring as the intake valve doesn't close before the combution stroke.
@Scotracer that must be why the bike sitting in my shed can do 18,500rpm all day with an engine build in the late 80's? and why a guy i knows mv does 16,000rpm? Valve springs with modern developments and tech or even smaller springs like 2-3 spring a valve setups (my old man has 3 springs a valve on his harley and that only does 6,000rpm?) can do this. I used to love the idea of ducati's desmodromic(?) springless design, but as it turns out, now days springs can achive higher rpm with stress..
i agree, its not all about the valves, the length of the stroke in the engine, and thus piston velocity during operation is smaller in motorbike engines and has alot to do with the rpm capcities in engines. for example the cbr 250r could hold at 20,000 rpm, with its 250cc 4cyl 4 cycle engine,which was achievable because of the low piston velocity
That crank shaft with, 8 pistons bolted onto it, is rotating 333 times every second. That's pretty impressive !

@Turbojeep23 i watched a program about the williams f1 team to get an engine to rev you have to make the parts as light as possible. the pistons are real tiny and everything is a special titanium alloy. the more revs u get the more fuel and air passes through the engine hence why you can get 1000hp plus from a 3 litre na engine.

@mrdangerous667 no so much as the pistons are "real tiny" as they have a very short stroke. This lowers the overall speed they come up to in order to move up in down in a given revolution of the motor. The shorter the stroke the lower the piston stroke speed allowing for higher RPM.

@fcguy7 by tiny i meant they are really short nt small diameter. the distance from the crown to the base is less than the diameter so it and the conrods etc weigh next to nothing because of the materials they are made from. also the tolerances are so small with the parts the engine is actually seized when its cold you have to heat the water and oil system up first so its such a tight fit in the bore that you get maximum compression.

@mrdangerous667 The size of the piston, crown to base, has little relative effect other than weight ... the crank determines stroke. Again, tiny pistons ... diameter or height ... however you meant it ...

@Turbojeep23 i'm not sure its a "big v8" im pretty sure the pistons are about as big as a hyabusa, maybe some what bigger.

@Turbojeep23 they are also like a stroke of only a couple of inches. no torque at all. just high speed capabilities

@Turbojeep23 They are not very big at all, a fair few jap i-4 bikes would have more displacement per cylinder then one of these f1 engines, dont quote me on this tho as i havnt really looked at much info on these motors.. 10k is amazing but an aussie guy has made a 4l 1uz-fe (quadcam toyota v8) get around 9,600rpm. And these are mass produced engines.. you can buy a v8 made with 2 hyabusa 1.35l heads, ranging from 400-650hp with different cam setups..

@Turbojeep23 2.4 litres isn't that large, especially not for a V8

@Turbojeep23 ive heard something about the valves being pneumatically powered after a certain rpm to prevent valve float but thats about it. also keep in mind that the pistons dont move up and down that much, they almost vibrate :P

@Turbojeep23 That's the thing, It's not a big V8. It's just a 2.4 which helps alot with the rpms. But still, the engine must have something special like you said.

@Turbojeep23 It's a dry sump, ik that for sure... As far as the valves go, I would THINK it is a full roller setup... but don't quote me...

Just to notice (rebuilding)? If it ever went @ that high an rpm it would be worse than a 425# Dremel. Stand back pls.

20000rpm v8 are you for reals...

Sure 20000rpm, the f1 engines are V8 and do the same amout rmps
Ariekebe 3 years ago
thats sick man...my stang can barely hit 7,000..lol....imagine 20,000...owned...those f1 engines are sick....what kind of valve train do they have you know, valve springs.etc...without preventing valve float...
indestructible306 3 years ago
This engine doenst come close the the price of you house. My Pinto engine (2liter) does 8000rpm and that cost alot of my money to make it. Spend +-5000euros. And 5000euros compared to that engine and shit.
Ariekebe 3 years ago
damn thats alot of money.....theres this guy with a v8 pinto that kicks ass were i live at...
indestructible306 3 years ago
indestructible, they have pneumatic valve return, no springs. Valve springs become useless after about 15,000rpm.

thanks for the info man...im gonna start doing some research on these engines...
indestructible306 3 years ago
They use air pressure to replace the coiled spring ....nice
indestructible306 3 years ago
@Scotracer and trying to figure out how to make them work, and work right is like shooting your self in the foot and trying to fill the hole with a second bullet.

@Scotracer if that! usually valve float will will occur much lower depending on the engine. then it starts backfiring as the intake valve doesn't close before the combution stroke.

@Scotracer spring operation is a requirement in F1 valvetrain. the pneumatics only stop the valve from bouncing.

@Scotracer that must be why the bike sitting in my shed can do 18,500rpm all day with an engine build in the late 80's? and why a guy i knows mv does 16,000rpm? Valve springs with modern developments and tech or even smaller springs like 2-3 spring a valve setups (my old man has 3 springs a valve on his harley and that only does 6,000rpm?) can do this. I used to love the idea of ducati's desmodromic(?) springless design, but as it turns out, now days springs can achive higher rpm with stress..
fergus1494 10 months ago
@Scotracer not true, lots of motorcycles go way higher than 15.000 and still use springs.

@slobowitz
i agree, its not all about the valves, the length of the stroke in the engine, and thus piston velocity during operation is smaller in motorbike engines and has alot to do with the rpm capcities in engines. for example the cbr 250r could hold at 20,000 rpm, with its 250cc 4cyl 4 cycle engine,which was achievable because of the low piston velocity

Not really if you have good ones they can hold up to 18k, some bikes have it ;)
