Keith Duckworth was amazing, the DFV was waaaay ahead of it's time, even for today's standards, 10500RPM and 510 HP is quite impressive! I mean that engine was designed in 1966!
400bhp in 1967 at its introduction in The Dutch Grand Prix, Not knocking the DFV. The Repco engine With SOHC was giving about 350 I believe. They tried a 4 cam engine but needed more money, so it failed. Colin Chapman demanded the engine carry suspension loads . The engine was a masterpiece of Engineering. Ford put a lot of money into that engine. The Westlake engine produced more power but was too complex.
@@JuanCarlos-tv2hu Yes I know that the very first DFVs made around 390-410HP back in 1967, but I meant that basically the same engine design of 1967 made 15 years later around 100HP more. The short stroke version Williams ran even made around 540-550. An incredible piece of engineering!
10,500rpm!!! My God what an engine build. I mean it's original design goes back to the '60's & it's not like this is a rotary or a screaming 500cc bike engine. So impressive.

Hello Dan, back in the early 90's, I was lucky enough to be sent via first-class British Airways to Germany by SDL (the company I was working for). As this was the only flight available. I was on the way to one of the first Burger King Drive-Through's as my company had made a new automated server window and the prototype had stopped working, and it was my job to fix it before the Burger King big-wigs arrived, to sign-off on a HUGE order. On the plane I couldn't believe it, because sitting next to me was my old neighbour (Bernard Ferguson). I hadn't seen him for 15 years, we had a great chat about how he remembered me making an electric bike and all that crazy stuff when I was a kid. He asked what I was doing now, I explained that I was now an electrical engineer but I really wanted to be a music-writer, however, for s***s and giggles I was building a car using an old 1500 pre-crossflow Ford Cortina engine, he seemed very interested, so for ten minutes I described my vehicle and what I thought was a warped inlet-manifold problem as it was hunting on acceleration, and ok when backing-off, for sure a vacuum problem. He then elbowed the very well-dressed man sitting next to the aircraft window who had listened silently to the whole story, and asked him "what do you reckon?" He leaned forward and said, "skim your manifold, it is a design flaw that on that engine there is an alloy inlet that shares its fixings with the steel exhaust manifold, and it warps easily!" So I said, are you a mechanic? He said, I am Keith Duckworth!!!! I tell you, I then felt so small I swear I fell down the back of the seat. Turns out my Neighbour was now Cosworth royalty and they were on the way back from Mercedes. Great to shake the great mans hand, he was so gracious he even gave me his complimentary bottle of Champagne... TRUE. What a legend. 🏆
At the time, Americans loved Drag Racing, Can Am, Trans Am, Formula 5000, NASCAR, Sprint Car, etc. A majority of these are either unlimited class, non stop throttle at high rpm or utilizes heavy road cars. So of course Americans would prefer a larger displacement, the DFV was never really popular in USA.
What Americans excel at is chassis building such as the Chaparral cars from Jim Hall. Many designs from F1 originated here. People like Colin Chapman and Gordon Murray adapted Jim Hall's ideas into F1.
@@steveluckhurst2350 It's fine though, Americans like Steve Nichols, designer of the most successful F1 car the MP4/4, are recently getting recognized. I love how people are now turning against Gordon Murray and his dishonest ways.
@@azynkron They would limit it now. Back then they would push it all the way. As reliable as it was, the Cozzer still suffered the odd catastrophic failure, more that today’s engines do.
@@Miatacrosser - Not quite correct Sir. The DFV (Double Four Valve) had its roots in the FVA (Four Valve A Type) family that was developed for the then 1600cc Formulas 2 regs. and was developed alongside it. The FVA overhead cams were gear driven and this was transferred to the DFV. The 'FVB' engine was in fact half a DFV @ 1498cc The BDA (Belt Driven A Type) was a development specifically for Ford rally cars to run in the 1600cc category based on the new Cortina Mk II iron block as the then Lotus Twin Cam using the Cortina Mk I engine could not be bored out reliably past 1595cc (it was originally a 1500cc Ford block bored out to 1588cc for production Lotus Elans, Europas and Twin Cam Escorts and Cortinas). But like all competition engines many versions of the BDA family went into all sorts of racing as well. Interesting crossover was when they created the 'FVD' using the BDA aluminium block bored to 1985cc for 2 litre sports car racing! This race bred aluminium block would find its way back into earlier iron block BDA engine rebuilds as a reliable 1800cc rally engine. Hence the 'RS1800' Mk II Ford Escort ... Hope I have added some background ....
Why? Because they tested the engine to make sure it will work properly when it's installed? That's the thing with this particular video - they WAY over dramatized the testing. That engine is designed specifically for this. As long as it was assembled correctly it will be fine - this is just the QC testing and to make sure it's performing up to specs. Nothing untoward happened in this video, nor does it regularly in that dyno, I'd wager. It's just testing function, not testing limits. You get horrible engine deaths when deliberately pushing them to see what breaks first, so you can then redesign that part better. That's part of design evolution. This was just function testing, so no real big deal. Not sure why the video drama'd it up, except for some 'fake TV drama', which is a modern problem completely separate from this discussion...
@@Broadpaw_Fox Have you built many engines? Have you many years of experience with engines that revs at around 10k? Have you spend many hours in a dyno room? Have you any knowledge in that it only needs ONE loose bolt to make that quite "uncommon" Engine which they have worked 1000h on to scrap metal? I doubt it.
Eric K Yes the hype narrating seemed for for general audience not car / mechanic audience. Should have just explained about dynos, controlled load and parameters being monitored. I do feel mean saying anything bad about the video though! Guy is awesome and is great content to be put out.
@@mrolsen6987 - I'm sorry to you mr. Olsen for your disappointment. Granted this is a UA-cam comment section, and anyone can say anything they want, but I've always made it a point to talk about the things I know. And you're right - any number of very small things could go wrong and destroy that engine while it's running hard. But that's part of that 1000 hours you were talking about in your post - they double and triple check all of those points to make sure nothing is left to chance. When that's finished and they go to the final testing after break-in, it should be understood that the engine will be fine - issues might pop-up during initial ring break-in that warrant addressing, but by the time you get to the point where this video showed the testing at high power, all the little issues have been addressed, and the engine will have been heat cycled a couple times. And if they really care, like these people probably do, they'll likely have gone in and retorqued everything after the first couple heat cycles. Of course, none of this was shown in this video, because this video wasn't about those details - which was the point of my original post. Thank you for your concern though.
True, but being an engine for high speeds you want more power for higher top speed... at least that’s how I’ve been told it goes. Torque to get going down low; power for pushing through the air at high speed.
Not long. Usually back then they set the revlimiter to increase the reliability. As Guy says, they want to get it to around 9500 rpm which is likely what he want's it to be able to rev to under racing conditions.
"Britain's finished we don't build anything anymore 😭" Uh huh. Apart from practically every performance engine and all the aero and vehicle design and and and and
@@thethirdman225 I remember it as 375 to begin with, but I could be wrong. I thought I remembered reading that it had 750 when turbos were approaching 1,000. Hard to believe they added only 100 considering engine technology was so crude compared to today when 200 HP per liter is not uncommon.
Heros are like elements aren't they, having just 1 is great if a little narrow minded, but if you have a few hero's and take something from all of them it makes you an even better person, an alloy of a person if you will.
I was thinking the same. But I'm quite sure they did, it's just not "good tv" to show it, so they just wen't straight to the "we rev the shit out of it part" and I loved it :o)))
Yeah, as said above, it very likely was properly broken in off camera. Just not important enough to take up their precious air time, which it seems they wanted to fill with unnecessary drama...
It will have been warmed up at about 5000 rpm to seat the piston rings and make sure the cams didn’t go flat, then run a couple of times at 3/4 throttle before the footage you see at full throttle. You don’t break a race engine in like a road car engine, if you do, they make less power so you have to go hard and fast with it after it’s warm. DFVs were stripped and rebuilt every 1000miles at the beginning of their life but that was at a 10000rpm, towards the end of their use, they were being stripped and rebuilt every 600miles when the rev limit climbed to 11000rpm. With that in mind, you have to remember that it lasting as long as your road car engine isn’t a worry, only power is, and that’s helped with an aggressive break in.
It's not a family saloon car engine. This might look similar, but you have to remember that it's purpose built by hand. They don't have to break them in in the same way since the tolerance is so precise. E.i. the parts fit perfectly from start, that's the difference.
@@azynkron - well, yes and no. Yes, the tolerances here are much tighter controlled than in assembly line engines, but you still have to wear the rings in to the cylinder walls, and you need to do a few heat cycles to make sure none of the parts are going to fail from the temperature cycling. But part that, I'll agree that a traditional break in isn't as necessary. Bed the rings on the dyno, do a couple heat cycles and it's good to go. :)
Yes but those cars are not big light go carts their huge cars, 450hp would be plenty enough for such small single seater f1 car, and 450hp was most probably the formula one limit at the time, there is actually a turbo version of the DFV called the DFX it made 800 to 1000 hp and could do 250 mph+, it was developed for indy car racing, it also dominated indy car for ten years too, the cosworth dfv is most probably the most successful engine in the whole of motorsport history not just f1, it also won 2, 24 hrs of le mans races in 1975 and 1980 www.museumofamericanspeed.com/cosworthindyengine.html
So it's a small displacement Naturally Aspirated Engine.. Seems they ran Cosworth's in Indy Cars for many years with Turbos on them .. Seems they were limited to 180 Cubic inches .. One year a low Budget Indy Team was competitive with a 350 Cubic inch naturally aspirated small Block Chevy engine that the block came out of a School bus.. Cubic Inches ,, Boost .. Nitromethane or Nitrous Oxide are the various ways to make more power.. I'd like to see how much power this Cosworth could make on a mix of 70% Nitromethane and 30% Methanol ..
The engine your referring to is the cosworth DFX which is a turbo DFV which made 800 to 1000hp and could do 250mph, the DFX also dominated indy car too Winning 10 indy car world titles plus constructors and 10 indy 500 titles in ten years, its also the most successful cart engine of all time with 150 race wins www.museumofamericanspeed.com/cosworthindyengine.html
I admire his accomplishments and I love the videos but I often find myself having difficulty understanding what he is saying...his accent and speaking style, at times, makes him hard to understand...
Listening to Guy is like riding a bike on sand. If you try too hard, ride too stiff you'll never make it. You have to ride loose and let your brain just put it together.
My godness, still struggling with "foot-pound" and "horsepower" ?, 8070 rpm, 219.9 foot-pound? should give 252,6 kW = 343,5 "horsepower" but the screen reports 357.8 horsepower(?)
FORD COSWORTH. I was once offered $40K to take a trailer loaded with F1 FORD blocks from El Paso, Tx to the Houston, Tx Ship Channel, CASH up front. I did NOT take the offer.

"Too much mechanical sympathy"
I also feel his pain.
When Guy said that I laughed because I felt the exact same way, I was crying inside for that engine and cringing as I hoped it wouldn't grenade.
I thought that I was weird for having the same feelings, if Guy feels the same way then, I'm absolutely sure I'm weird but now I'm alright with it.

No. It came out of the gate at about 410 hp in 1967 and went up from there. It increased by about 100 hp over 15 years.
@@thethirdman225 I remember it as 375 to begin with, but I could be wrong. I thought I remembered reading that it had 750 when turbos were approaching 1,000. Hard to believe they added only 100 considering engine technology was so crude compared to today when 200 HP per liter is not uncommon.
I always thought Guy's hero was Barnes Wallis.
Heros are like elements aren't they, having just 1 is great if a little narrow minded, but if you have a few hero's and take something from all of them it makes you an even better person, an alloy of a person if you will.
Iv been married 22 year and I am straight.but if he ask me to move in with him tommrw I would 😂😂
Haha...
@Jason Bouphasavanh I totally agree with you. Honda and Yamaha are one of the most reliable brands.
Surprised the fresh motor is not broken in at lower RPM's
I was thinking the same. But I'm quite sure they did, it's just not "good tv" to show it, so they just wen't straight to the "we rev the shit out of it part" and I loved it :o)))
Yeah, as said above, it very likely was properly broken in off camera. Just not important enough to take up their precious air time, which it seems they wanted to fill with unnecessary drama...
It will have been warmed up at about 5000 rpm to seat the piston rings and make sure the cams didn’t go flat, then run a couple of times at 3/4 throttle before the footage you see at full throttle.
You don’t break a race engine in like a road car engine, if you do, they make less power so you have to go hard and fast with it after it’s warm.
DFVs were stripped and rebuilt every 1000miles at the beginning of their life but that was at a 10000rpm, towards the end of their use, they were being stripped and rebuilt every 600miles when the rev limit climbed to 11000rpm. With that in mind, you have to remember that it lasting as long as your road car engine isn’t a worry, only power is, and that’s helped with an aggressive break in.
It's not a family saloon car engine. This might look similar, but you have to remember that it's purpose built by hand. They don't have to break them in in the same way since the tolerance is so precise. E.i. the parts fit perfectly from start, that's the difference.
@@azynkron - well, yes and no. Yes, the tolerances here are much tighter controlled than in assembly line engines, but you still have to wear the rings in to the cylinder walls, and you need to do a few heat cycles to make sure none of the parts are going to fail from the temperature cycling. But part that, I'll agree that a traditional break in isn't as necessary. Bed the rings on the dyno, do a couple heat cycles and it's good to go. :)
5 months to rebuild a engine? And when I take 2 days to finish a whole truck im called slow -.-
!000 hours to rebuild? What did they do cast a new block?
Cosworth DFV sponsored by Ford.
Should've been marked NSFW ;)
to think the group 5 cars made more horsepower than this engine
Yes but those cars are not big light go carts their huge cars, 450hp would be plenty enough for such small single seater f1 car, and 450hp was most probably the formula one limit at the time, there is actually a turbo version of the DFV called the DFX it made 800 to 1000 hp and could do 250 mph+, it was developed for indy car racing, it also dominated indy car for ten years too, the cosworth dfv is most probably the most successful engine in the whole of motorsport history not just f1, it also won 2, 24 hrs of le mans races in 1975 and 1980

Love your work (quirk?) GUY.
ADHD diagnoses pending....
Aspergers
Obviously thay most of let the engine heat up...not just start and rev flat out...lol
So it's a small displacement Naturally Aspirated Engine.. Seems they ran Cosworth's in Indy Cars for many years with Turbos on them .. Seems they were limited to 180 Cubic inches .. One year a low Budget Indy Team was competitive with a 350 Cubic inch naturally aspirated small Block Chevy engine that the block came out of a School bus..
Cubic Inches ,, Boost .. Nitromethane or Nitrous Oxide are the various ways to make more power..
I'd like to see how much power this Cosworth could make on a mix of 70% Nitromethane and 30% Methanol ..
The engine your referring to is the cosworth DFX which is a turbo DFV which made 800 to 1000hp and could do 250mph, the DFX also dominated indy car too
Winning 10 indy car world titles plus constructors and 10 indy 500 titles in ten years, its also the most successful cart engine of all time with 150 race wins www.museumofamericanspeed.com/cosworthindyengine.html
I know he would put it in his bedroom
Ballast the alternator. 17 volts My money is stolen and I need help?
I find myself relating to guy more and more each episode. Just not nesrly as knowledgable.
Williams Larry Lewis Kevin Wilson Donald
Hahahaha guy destryong the mechanics, suprised you wernt offered a job mate.
infantile piano because....?
My daily 125cc rev limit is at 10500rpm. Revs higher than a race engine 😂😂
But you only have 1 Piston, this "Race Engine" has 8 😂
Seen a Ferrari v12 ... They scream ahaha
I admire his accomplishments and I love the videos but I often find myself having difficulty understanding what he is saying...his accent and speaking style, at times, makes him hard to understand...
Listening to Guy is like riding a bike on sand. If you try too hard, ride too stiff you'll never make it. You have to ride loose and let your brain just put it together.
My godness, still struggling with "foot-pound" and "horsepower" ?, 8070 rpm, 219.9 foot-pound? should give 252,6 kW = 343,5 "horsepower" but the screen reports 357.8 horsepower(?)
The voiceover is annoying, ridiculous and old fashioned 👎🏽
I like it
no run in because that's just a con. It's even guna work and make the power or not
FORD COSWORTH. I was once offered $40K to take a trailer loaded with F1 FORD blocks from El Paso, Tx to the Houston, Tx Ship Channel, CASH up front. I did NOT take the offer.
