I’d rather have 1000ft lbs if torque. Lol

Jared Kushner really is smart! :D

A littel bit more 500hp it should compete with bugatti

Cosworth Engine FTW

valkarie with no bumper lol that would be fast (twin turbo)

Boosted engines are street legal.

at first look I was thinking "what the hell is a NAVIZ engine..?" - ooooh Natural Aspirated V12. *Facepalm -

Cosworth no more explanation needed

193 hp at 5500 🤣

RX8 Renesis = 183hp per liter

How about fuel consumption?

My question is... How are you so awesome? I just love your videos you are an information highway. Passion for your line of work is brilliant. Bless you, my good friend, merry Christmas, and a happy new year. See you in 2021.

OK WELL DONE!!!!!.....but now i want it boosted 🤷‍♂️

First motor "Revs to only 11,100", is this the new normal or am I missing something?

great presentation ! there are times when my eyes begin to glass over on some of your videos. this absolutely was not the case with this one. it was succinct while being very comprehensive. you also made superb conclusions that brought true insight to the analysis. others should use this video as a benchmark !

IIRC the posche Carrera 6 (906) street legal (homologated) racing car produced 370bhp from a flat 6 2 litre engine in 1966

More impressed by a street legal engine turning over 10k. Im dissapointed by only. Nust under 600 ftpnd of torque. Love to have the car though.

Why not twin turbo it?

You can build a high compression 305 abc and it’ll still be lighter

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 .

White people are amazing.

If you’re concerned about reliability this kind of car probably isn’t for you

I'm here for all the comments saying "naturally aspirated is incorrect"🤣🤣

Cadillac CTS prototype. Check it

I wonder how much more efficient this engine could be if running Freevalve technology.

He said SIZE DOES MATTER!!! For engines 😂😂😂😂😂

This is not that remarkable. I can think of 10 ways to make 1k hp and 5 of them naturally aspirated. You do realize that virtually every farm tractor out there makes more that 1000 hp at much lower engine speeds. Airflow = Hp.

Why 65degree, I thought 60 was optimal? Are they using split crankpins or just uneven firing?

Let’s boost it

Just boost your 2JZ GTE ez

You know I cracked the code years ago, right?

Our demand for v10 or v12 f1 engine's has been taken into account and given back to us at an even better option . A street legal one

From Fraser, husband of Leslie All very nice, but do you really need anything like this for a road car ? Of course not !!

“Size of course, does matter”😂

love the channel just commenting for the algorithm

Anyone else want to give this thing ALL THE BOOST?

Surely when you're at La Paz in Bolivia The engine wouldn't make 1000hp. Maybe something like 800 Because its high above atmosphere

My LMM Duramax has the opposite power torque numbers. Lol I'm sitting close to 600hp and over 1000ft/lbs of torque.

I've seen a Ford 363 cubic-inch small-block do the same thing on pump gas and that was about 10 years ago. So what's the big story???

From just the RPM at max power and engine size, I too came to the conclusion that the stroke would be between 65 and 70 mm. I have an equation that models the relationship between the real world power curve with basic engine specs.

I was taught foot pound and have been using that my entire life. Now I'm hearing pound foot and life will never be the same.

Kind of like always hearing Newton meter, and then someone switches to meter Newton

Since its naturally aspirated seems like it wouldn't put out that horsepower at slower speed, regardless of rpm.s

Imagine the horsepower after you throw in a fat turbo then retune it. Sheesh

Wow.....the explanation is incredible.....thank you!

Only lasts how many miles?

I'll believe it when it actually gets sold to the public and vehicles get registered as street legal in EU. Til then, there's nothing street legal here yet.

Run Berry Run

Well I mean they're getting 500hp naturally aspirated building k series Honda motors so I don't see how this isn't possible

So naturally we supercharge it

Did you ever find out what the compression ratio is of those engines in the bore and stroke? I’m guessing at that rpm the runners are huge and big valves with a target lobe separation to be around 101-103? They have to be utilizing scavenging properties at that rpm. I’d love to see the flow numbers of the heads with everything connected. Please let me know if you can find any info thanks. Great video. You should make a video explaining your math your using

I used to like cars , but have realized humans are obsessed with cars for some reason. My only theory is they can't run fast any more... Restore old cars , and drive them till we can phase them out. Hopefully we won't developed another environmental catastrophic economy next time 🤥

Static compression ratio is just as irrelevant now as it was 50+ years ago. Dynamic compression is the only thing that matters and that is variable depending on rpm due to the 'pulse tuning' you kinda touched on. Another reason for using multiple injectors is the duty cycle. Using port and direct means both can be smaller and be combined to get correct F/A ratio almost all the time. It's been done on motorcycles revving much much higher for at least the last 10 years (as has chain driven DOHC to 18~20,000rpm) a V configuration engine has other issues with chain drives though not just the chain whip at high rpm,

I feel like for a 1k car 546 lb ft of torque isn’t enough , I would like to see that close to 800 at least , Lolol idk , something about an engine that doesn’t have close Hp and torque numbers bother me , also , I don’t wanna have to rev the car that high to get the power i want

All I can see is the valve covers holding the engine into the car and thinking good lord you never want to service anything on this thing.

200+ kg for a car lol some motorcyles weigh more than that car

Okay so slap a turbo on it now

I would love to see a single episode explaining the math inside the intake manifold. Timing the impulse pulses relating to the high pressure zones moving across runners is fascinating.

Nice video, but was just wondering why port injection has emission benefits over direct injection in this application?

Don't forget that fuel displaces intake air with port injection. You can potentially get a few percent more power with DI because of this.

Yamaha made a street legal emissions compliant 400 cc engine that made 140 hp 2 decades ago thats 350 hp/liter at that rate why aren't these at 2200 hp?

Size does matters for engines 😅😅😅

And let's be honest about the endurance factor with this engine. It's purely hypothetical as NO ONE is going to be driving this sucker for 100k kilometers or anything close to that.

So, clearly, the answer is to develop an engine that will rev to 100k RPM. Count me in!

Kr1s = 25,000 RPM.

153bhp per liter, isn't much at all compared to a Motorbike. About 200bhp for a standard R1, and over 260 for a MotoGP bike. Makes 153 look pitiful.

Can you use kg and km decause we don't know what .. lbs

Now... can we boost it tho?

the real question is what happens when you quint turbo it, tho

I always wonder with these stressed-member engine scenarios, don’t all those forces risk flexing on the extremely tight tolerances of the moving parts?

My car makes 74.21875 per liter. Makes sense since this engine makes over twice as much power and spins twice as fast. I have a v8 6.4l hemi makes 475 hp and 475 lbs feet of torque.

If the Valkyrie cost is 3 million not including running costs it's only $30 per km before a new engine is needed

Time/area, (cam profile, port area, Mach numbers) have to match RPM. Bore/stroke, rod length effect torque.

I wonder about the 7.7 litre Speed 12 engine from TVR made in the 1997. How that would compare with this.

It's my understanding that timing gear on the back of the engine is getting more common due to efficiency. BMW and mercs have had chains on back for years now. Not 100% sure why, but id guess it's down to the design of the crank and bearing assembly.

O waw u speak about a car that probably won't exist ever. One guy from my country "bought" one last year (or 2, idk and idc) and he didn't received it not at this day.

Thanks for this nice video about these V12 engines. My question is: why 65 deg of cylinder banks angle instead of 60 deg? Just curious, and thanks in advance for your answer. Keep up your good work!

I want to know about ford 427 , 7 litre engine plz make a video on that

If u want an engine to rev high just buy a rotary. High rev and a mobile flamethrower, can't beat that.

The real question here is “will it fit in my Honda”.

Considering that race engines might last around 1000 - 2500 miles, 60,000 is quite a bit for an 11,000+ RPM machine!

I wonder if you could hit it with a 150 shot of Nitrous

Can you explain in detail how you calculated the horsepower at certain speeds and where it comes from and what is the number 5252 means?

Put... Put an ls in it 😅

The engine makes 1000 bhp, not hp. It’s on their website. The Valkyrie is dual ignition, it has 24 spark plugs. That’s interesting. Japanese motorcycles revved to 14k 20 years ago. Why don’t we see this on high performance sports cars commonly? Because the Valkyrie’s engine requires a complete rebuild every 62k miles! And with that engine being a stressed member, God forbid you crash it or someone crashes into you. No AC/heater, sound system... hmmm... Mercedes Benz Project One (electric windows and AC are standard) sounding better and better. Now as for all that heat and flammable carbon fiber resin: 5,900 Lamborghini Aventadors recalled - fire risk. 2763 McLaren Senna/720S’s recalled - fire. Bugatti Chiron and Veyron multi-year recall - fire. 2150 Ferrari 458s recalled - fire. Just saying! There’s fantasy world, then there’s the real-world driving. Don’t know the ground clearance on the Valkyrie but Hypercars routinely have front suspension lift systems now, can this thing handle a speed bump in a parking garage in Beverly Hills?

Old school mopar hemi with No computer and carburetor on pump gas can make 1k horsepower.

Your point is? Theres more to an engine than peak horsepower.

Those free government phones should have explosive charges that detonate if you troll a good NOlocal video. That way these geniuses that are smarter than everyone else but own nothing but clothes and a free smartphone will be relieved of their miserable existence.

Why assume all the down force in in the center of the car? Down force is applied at the front and the back, by splitters and spoilers.

Why 65 degrees bank angle and not 60 degrees? A 60 degree bank angle is naturally balanced with a V12. Divide the number of degrees of crankshaft rotation needed for each cylinder to fire once by the number of cylinders. That is 720 degrees of crankshaft rotation for a four stroke engine. The result is the angle between crank throws needed for an engine to achieve primary balance.

The lubricating requirements on that engine must be just as engineered as the engine itself. Operating at that high of rpm it probably does what the 6.0 Powerstroke does to oil. Itll sheer 30w down to vegetable oil in no time. Gas turbine oil? Synthetic no doubt.

Boost isnt a crime

So, you say they made a I3... 1000/4=250. A 250hp NA 3 cylinder?! Oooh, or a 333 hp NA 4 cylinder... lots of cars could use one of those...

About time the car manufacturers started getting close to motorcycles lol. The technology has been on the roads since the 90s.

Jesus Christ. Can you give a presentation that isn’t like we’re sitting in a freaking class in college or whatever? Lord. Lost my attention... & people know how engines work.... gasoline & diesel are the same except for one firing from spark/fire & the other by highly compressed air & fuel.... nothing is different... with this engine.
