This Brilliant Engine Makes 1000 HP Without Boost!


The Most Powerful Naturally Aspirated Engine In A Road Car
Aston Martin's Valkyrie Engine Has 1,000 HP, Revs Past 11,000 RPM!
Recommended Books & Car Products -
The Aston Martin Valkyrie has the highest horsepower naturally aspirated engine in a road car, at an incredible 1,000 horsepower! That's over 150 horsepower per liter, and it revs over 11,000 RPM. It's an impressive V12 engine built by Cosworth, but they're not stopping there. In the Gordon Murray T.50, another naturally aspirated V12 engine is used, this time revving past 12,000 RPM! In this video we'll discuss how these engines work, how they reach such high horsepower levels, and compare them to other engines. We'll discuss the engine structure, displacement, BMEP, RPM, cam gearing, fuel injection, and just how quickly the McLaren F1's successor engine can rev. Enjoy the video!

    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 .

    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

  • 1crazypj
    1crazypjMåned siden

    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,

    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.

    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?

    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.
