- BMW F1 car BT52 Engine Assembly.
The history of Formula One is replete with compelling stories. A number of particularly spectacular episodes will be recalled on Sunday, 21 June 2015, as part of the Austrian Grand Prix world championship event. Eight historic vehicles from motor sport’s crowning discipline will be lining up for the Legends Parade at the Red Bull Ring in Spielberg with former F1 racing drivers at the wheel - including a reunion with three-times Formula One world champion Nelson Piquet. In 1983 the Brazilian became the first driver in the history of Formula One to win the world championship title in a racing car powered by a turbo engine: the Brabham BMW BT52. At the Legends Parade in Spielberg, Piquet will once again be behind the wheel of his championship-winning car, which today belongs to the BMW Group Classic collection.
The engine that imbued the Brabham BMW BT52 with its legendary status was developed by BMW Motorsport GmbH under the guidance of its then Technical Director, Paul Rosche. His team furnished the British Brabham racing team with a 1.5-litre four-cylinder unit featuring 16 valves, a turbocharger and - in a first for Formula One - Digital Motor Electronics. This mix made for an awesome power potential, with experts estimating its maximum output at up to 1,400 hp. Rosche’s response to such speculation was typically understated: “We don’t know for sure as the dyno didn’t go beyond 1,280 hp.”
The BMW turbo engine was first deployed in a Formula One race at the start of the 1982 season; 630 days later Nelson Piquet drove the Brabham BMW BT52 to world championship victory. His title win marked the close of an unusually exhilarating season in which Piquet started from pole just once but clocked the fastest race lap four times and won three out of 15 races. He made eight podium appearances, collecting 59 world championship points over the season to take the 1983 Drivers’ World Championship title.
The race car Piquet piloted along the road to victory continues to impress to this day with its 1980s-style arrow-shaped design and its extraordinary engine power. It is thanks to the BMW Group Classic team responsible for historic motor sport that the Brabham BMW BT52 is once again demonstrating its prowess on the race track. In 2013, exactly 30 years after Nelson Piquet’s triumph, the racer was roused from its automotive retirement and ushered back onto the race track. Numerous mechanics who were involved in its development more than three decades ago were recruited for its extensive restoration - among them Paul Rosche. The upshot was experienced for the first time at the Goodwood Festival of Speed in July 2013. The Brabham BMW BT52’s involvement in the Legends Parade in Austria will be its third appearance since its revival.

1300 hp, 4 cylinders, in 1984. This is why modern F1 has pushed me backwards. I'd rather study the history than concern myself with the 2019 season.
This engine as amassing as it was, was only MAYBE good for 1 or 2 laps qualifying trim and MAYBE make it through the race.
Beast of an engine, but unreliable.
Engines now are way better.
Great Video!
1984 it was "only" 950hp in qualifying. In 1986 it had an estimated output of 1400hp.
Imho the best engines were the 3l NA engines at 19k rpm with nearly 1000hp.
When you see a bunch of old German Mechanics smiling around an engine you gotta know something good is about to go down.
Or blow up
Steven SteveO ok amerikkan lol
That smiling old bloke is Paul Rosche.
Only the best driver and chassis/suspension maker in the world to overcome all difficulties and be world champion with an average team! Great Nelson Piquet from Brazil!
Awesome video of one of the greatest F1 engines ever developed. The smile on Mr. Rosche's face says it all!
Am i the only one who finds these videos of engines being built oddly satisfying?
No, you're not the only one.
I love the sounds of two surfaces being mated up and bolts being torqued or the simple way the mechanic wiped down components with a paper towel. Artificial intelligence and robots are taking this away these skills and now man is a component that is soon to be superceded. Handmade really does stand for something.
@@rockers2rockers616 or the sound of a large diameter drill bit peeling away at the metal that it's going through. Not many people understand the beauty of that sound.
No. There's nothing odd about it. It's visceral and indulgent to our gearhead ways.
Nope!
I love that these guys are in Germany and Credence Clearwater Revival was on the radio! 👍🏻👍🏻👍🏻
That's the legend himself, Paul Rosche, showing up at the end. It's cool to see the old timers at work with their spinner ratchets and no rubber gloves!
I knew I recognised him, thanks.
Look at the care, the painstaking attention to detail, the respect for the parts, the pride and love in their work.
THIS is truly expert craftsmanship.
They better take care with those parts I'm positive every thing they touched cost hundreds of thousands of dollars, the bolts alone are probably 10k
@@oldleatherhandsfriends4053 the block is a basic 4 pot road car block. Lots of trick bits thrown on but hardly exotic these days.
Love the “old school” technicians. No gloves, just dirty, greasy hands.
I wish they could still build engines like this. Gear driven shafts... No belt, no chain... Hairy piece this one...
old nissan sedans were gear driven
Honestly idk why they don’t use gear driven shafts today. It’s much more reliable to belts and chains it seems.
More contact surfaces = more friction. More complex assembly = more expensive. Also, more bearings to fail and misalign. Formula 1 engines get a lot more engines than a typical road car.
Gear driven used by Honda in racing endurance HRC motorbikes... RVF 750 RC 30, RVF 750 RC 45 and VTR 1000 SP RC51... and many more top CLASS Honda motorbikes
changing them gear bearings would be alot more difficult then changing belts or chains, plus engine noise/vibration wouldnt be the normal consumers cup of tea in a road car
It's so nice to watch these old craftsmen build this beautiful engine.
Und am Schluss sieht man den Meister nochmal, Paul du genie👍
I remember reading about this back in the 80s. For qualifying runs Brabham/BMW made what were called "grenade motors" with insane boost pressures for super-high output, that would last only a dozen laps before destroying themselves.
like 80 psi of BOOST!!!!!!!!!!!!!!!!!!
they used to seal the wastegate shut! ....They do that in modern V6 F1 engines but the difference being modern F1 engines now have MGU-H motors on the turbos allowing the spool of the turbo to be at discrepancy of an electric motor, and therefor can harness off-throttle which allows the turbo to not always be on boost -like the qualifying engines you mentioned, with their wastegates sealed.
The BMW M10 4 cylinder turbo engine: pound for pound, the best engine to ever power a Formula 1 car! Nothing else was even close!
Wow that carbon fiber compressor housing is pretty sweet
They boosted these engines up to 80PSI. For comparison, a Bugatti Chiron’s turbos boost to 18PSI.
To me this was the pinnacle of F1 😎
Look at the duration on those cam lobes!
Ein M10 mit Power; nee, scherz beiseite, eine tolle Präsentation von Skills und knowledge. Ich bin stolz auf Euch.
5:11 What an event! Even the CEO of Mercedes was there XD
Beautiful, would love to have the knowledge to be able to rebuild an engine like this. Proper old school and I noticed not a torque wrench is sight.
the torques used are kept strictly confidential.
I can watch these kinds of engine build all day
These are the kind of guys who don't need torque wrenches, they can just do it perfectly by hand.
Dat turbo...
That is no turbo...... that is the drum of a washing machine...
;)
@@mverbaan3381 it looks like a turbofan engine attached to a combustion engine lol
The turbo is nearly the size of the engine!
I read somewhere they used old production-car blocks, with high mileage. Somehow the metal had "matured" and they were more reliable.
yeah, it was in the documentary about the engine itself, you can search youtube for that
BMW used the blocks from road test very high mileage engines, the milage "settled" the cast iron blocks so when re-machined/bored etc they held the tolerances better. They were very carefully selected and all burrs and casting marks were dressed smooth so as to not start a crack, needless to say, they were X-rayed during the inspection
Off the top my head , it was a production road car cast block they used high mileage at that , and then left outside apparently .
Not sure if was from the BMW 2002 series cars with a different stroke but they used a standard production block .
That Turbo I am guessing was original ment for a truck .
The lag must have been amazing waiting for that to spool up.
But very typical of the day when many teams still used off the shelf parts.
Great piece of history though.
5:00 Paul Rosche "Nocken-Paule" R.I.P !
Cargofan Master engine builder thank God for this guy we have some of the best engines ever produced
the only man who could make a stock block from a road car to the most powerful engine in f1..rest in peace
O motor mais FANTÁSTICO que a F1 já teve....
Menuda obra de ingeniería de Paul Roche ,el mejor ingeniero de bmw el famoso motor M12 y M13 1.5 litros de cilindrada ,rodaba 15000 rpm que lastima ya no hay ingenieros como el ,hizo mucho por bmw buenos motores menuda leyenda tiene ese motor en el fórmula 1 ,después diseño más motores como el v10 de fórmula 1 ,y otros más montaba motores usados para que no se rompa en carrera por las tensiones ,como experto en bmw un saludo a todos por exponerlo en el Museo de bmw
Epic car, epic engine, epic driver. Great times!
A lot of knowledge with those gentlemen for sure. Great video 😁👍
Somebody told me that the guy that let the gasket fall had to clean the toilets in the workshop for 2 weeks.
Serious note: BMW has been able to build an engine doing up to 1200 HP in qualifies, and 800 in a race, that looks like an engine with nothing special, like you can go into a BMW showroom and buy one: that is insane.
Some years later, they put some of the tech into the 4 cyl 2.0 on the 320is (190 HP and high revs), and the 6 cyl 3.0 in the M3, turning the E30 series into something that really made sports car's history.
This is simply beautiful
What a difference having the right size sockets makes. I should buy some new ones.
the good old way to build a f1 engine: hand tools and experience
It still amaze me how technology works, thank God for smart people.
That turbo is almost as big as the engine! 😳
I'm surprised that so many are involved with assembling the engine- I would have thought it would be done by one man.
I think...the most amazing engine in F1 history..
Legend has it, the core blocks were left outside to weather, and mechanics would piss on them, over time ,before they were brought back in, and "blueprinted" and assembly began. As an American, of German heritage, this seems like just the right thing.
Believe that and you will believe anything mate!
They just rebuilded their own engine that they made.
Legendary Megatron !
Artisans at work
Perfection
That turbosize explains quite a lot: It is more a turbo with an engine, than an engine with a turbo!!!
Steen Lassen I know what you mean these old turbos where so inefficient they had to be huge.
It also has to supply 80 odd pounds of boost to an engine spinning at 10K+ rpm, so it has to be huge.
Napier discovered this with their compound turbo aircraft engines. The turbos were developing more power than the piston engines they were attached to. This is why they soon switched to turboprop engines
"There's no way this made 1280 horsepow.... *sees the size of the turbo* oh... I see"
😜🤣🤣🤣👍
Jajajaja
Approximately 1400hp for qualifying.
When these engines were new, the cylinder blocks would be put outside to "weather" and the mechanics were even encouraged to "P" on them, apparently it makes the castings tougher! Probably smell funny when first started too!
I heard they used old blocks from warranty return engines, already stress relieved, then they left them outside,
This was the best asmr I have ever seen
2:27 - Grande NelSHOW Piquet. MITO.
Inizio anni 80, i materiali erano quelli che erano, le conoscenze anche......4 cilindri 1.500 cc mono turbo: 1.280 cv!! Fantastico!!! TOP TOP TOP!
4:14 interesting that they mounted the throttle right ahead of the compressor wheel.
Wow man this makes me wish that I pursued a career in motor mechanics or some sort of engineering 😥😥
All of this is so German.
In a rebuilt normal road engine you'd expect the bores to show hone marks for retaining oil , but these looked polished which is really interesting . These BMW boys must know there stuff .
With BMW motor is their middle name.
As it is „basically“ an M10 engine I am very proud that my 1502 is at least some kind of an F1 car! :D
the only close thing to the M10 engine here is the block but even that is most likely reworked lol
Throw that into a golf cart, and you'd have a beast of a car.
This is the m12 engine right? They made this engine from the M10 that powered the 2002's,520i e28 and the 318i e30( early versions)
I believe you're correct. I know its before M3. Just the block though. Dry sump and different head.
sauber ! bmw immer gut !
when i saw the turbo , than i understood.
FrankValchiria I know what you mean old turbos are so inefficient they have to be huge.
That would be the best job. Those are some lucky dudes.
the size of that turbo !!
Great Video! Nice to see Nocken Paule 👍
4:05 😃 Great photo!
So wish I could have taken my time like this when I worked in a remanufacturing plant, and not have been driven by a merciless time clock/boss to get 600 or more of these done in a lesser amount of time.
Great video for an amazing engine! camshafts specs?
Great video!
I’m sure this engine is similar to the Ford 4-15T
4 cylinders, 1.5 litre turbo.
I saw one on a dyno ages ago, I’m sure it made around 1000bhp.
As said great video.
I'd like to see James May build this engine. He might finish it before the earth blows up...
Isn't this the famed...."Megatron" F1 engine capable of 1,300 + HP in qualifying tune?
Putting the ‘M’ in #ASMR 😂
Old school mechanics, visible and tactile - no fancy pants energy recovery or super dooper electronics/computer systems here...
beautiful awesome work.
I bet those cam gears scream with that straight teeth profile!
I miss BMW F1!! 😪
Great video, vert interesting, but, there are far too many close up shots. Camera work in general is very poor. What a shame.
Thats a manly 4 banger ^^
Very satisfying video.
If anyone ever threw a ball to you and you instinctively reached out and caught it, doing intuitive maths to put your hand under the arc of the ball, chances are it's because you've caught a lot of balls (wait, am I on the internet? There's no way a ball analogy could backfire!). This is what you're seeing here. Each measurement, wipe, tighten looks so obvious, because they make it look like catching a ball. Love it to bits. Kudos engineers :)
I wonder if these guys are all just "volunteers" doing this work as a labor of love. I can't imagine that many senior techs working on a factory restoration and getting full pay.
Why is there no honing lines on the cylinder bore? What is the science behind that?
Throwback Event Proposal, Penske Offenhauser vs BMW 4 cylinder engine build, dyno and performance comparison at Indianapolis in 2022...
I’ll take two please. Thank you.
they didn't use torque wrenches at all it was very strange.i woulda figured they would.
+Chris Silva They were, unibody torque wrench, i.e. each wrench has a 5nm rating etc, so you have to have 20 of these uni wrenches to equal an actual torque wrench
its faster though
thats pretty freakin genius....
Huh ok.ill watch again.
Chris Silva noticed that too , guess those old dudes know what is jussssst right😄
Chris Silva ____. Not all bolts have to be torqued. They only torque the ones that need it.
Thanks.
But, what kind of piston material and brand did they used in this planet's one of Best engine ???
Did anyone else see how easily he spun that crank by hand?
Good work
I see no torque wrenches, only good old traditional ''feel''. Nice.
In public auto timing chain 100k end time to say good bye :D in f1 timing gears.
Excellent men.
Esto es cuando antes Bmw hacía motores de verdad no como estos de serie N52
I find it very interesting that there is no girdle on the bottom end. Maybe no one had thought of it back when this engine was being raced.
They knew about girdles, it just didn't need them. That little block is a beast
why in the engine block to 0:55, is reworked I speak of refined and polished halves ?
Wonder if modern F1 engines have gear driven timing. General aviation still uses it on its air-cooled engines and the engine of the F1 bolts to the body similar to general aviation.
So the throttle body is placed before the Turbo ?? *interesting*
3:58min mein Dad mit auf dem Meisterschaftsfoto in der Mitte 💪 #stillproud !!!!
You really are lucky
i didn't know megatron had a carbon fibre compressor housing, rad.
Beast...
Camera works could be better..is this a 4 cyl..or?
That 1200hp engine only has 1 cam per head operating induction and exhaust?
How many engines did they run on a race weekend?
That finger on the piston in the beginning...
