BMW F1 Car BT52 1,280 hp Engine Assembly

[@LuxeXx]

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.

[@ESHANABROOK]

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!

[@M0bel]

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.

[@ThrowingItAway]

When you see a bunch of old German Mechanics smiling around an engine you gotta know something good is about to go down.

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.

[@oldleatherhandsfriends4053]

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

[@simonjeacle4732]

No, you're not the only one.

[@rockers2rockers616]

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 Artificial intelligence and robots are taking this away these skills and now man is a component that is soon to be superceded.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.

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.

[@paulos.csilva3717]

the torques used are kept strictly confidential.

[@tech9803]

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.

[@akasakakv9523]

like 80 psi of BOOST!!!!!!!!!!!!!!!!!!

[@aureliobrighton1871]

Just saw a clip about the Brabs. They recalled 1 or 2 laps before 'Poof', special fuel, superhot engine computer, ice and water, plateing, bent gearboxes before completing one lap. Regular road car 318i block left out in the rain for hardening. Engine block (and Chassis) split in half on the track by extreme boost. And drivers who demanded 'More' in order to beat Renault. "You steer it round the corner, watch for ample space for snaking, then just floor it. No way you can 'drive' the thing." Engineers, what a breed. ;)

[@autotalon]

Wow that carbon fiber compressor housing is pretty sweet

[@Skyisnotalimit]

I wish they could still build engines like this. Gear driven shafts... No belt, no chain... Hairy piece this one...

[@MoiPloy]

old nissan sedans were gear driven

[@OggaDugga]

Honestly idk why they don’t use gear driven shafts today. It’s much more reliable to belts and chains it seems.

[@EmyrDerfel]

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.

[@carlosrubio8234]

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

[@sockpuppets7256]

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

[@Secret72062]

This was the best asmr I have ever seen

[@davidrudolph2825]

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!

[@johntechwriter]

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.

[@flakey7832]

yeah, it was in the documentary about the engine itself, you can search youtube for that

[@barryfowles-zl5ib]

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

[@clockdva20]

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.

[@Juhnu]

These are the kind of guys who don't need torque wrenches, they can just do it perfectly by hand.

Very satisfying video.

[@jasonmames5329]

Wow man this makes me wish that I pursued a career in motor mechanics or some sort of engineering 😥😥

[@VTLIFE-so4dc]

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.

[@patbutete1722]

With BMW motor is their middle name.

[@gerry343]

I'm surprised that so many are involved with assembling the engine- I would have thought it would be done by one man.

[@stevefuller1779]

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!

[@patgill4968]

I heard they used old blocks from warranty return engines, already stress relieved, then they left them outside,

[@Virtuoso23]

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.

[@yxng_metro]

They just rebuilded their own engine that they made.

[@Stormas3000]

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.

[@DoriFord]

Kugelfischer fuel injection pump - it was popular until early 90s, you could pump huge amount of fuel easily

[@memadmax69]

Dry sump oil pump

[@ETicketM]

It is a Kugelfischer mechanical fuel injection pump. Similar to a direct injection pump but the injectors are in the intake plenum not the combustion chambers.

[@fuckjewtube69]

That looks like a fuel injection pump. You can see the 2 blue fittings could be supply and return lines and then there's 4 line for each cylinder. But I don't know for sure.

[@mcqcjc8409]

Why is there no honing lines on the cylinder bore? What is the science behind that?

[@MM-ev4sc]

[@MrWoowootila]

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.

[@steenlassen5718]

That turbosize explains quite a lot: It is more a turbo with an engine, than an engine with a turbo!!!

[@Big2009Gee]

Steen Lassen I know what you mean these old turbos where so inefficient they had to be huge.

[@oldleatherhandsfriends4053]

It also has to supply 80 odd pounds of boost to an engine spinning at 10K+ rpm, so it has to be huge.

[@Buzdu22]

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

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 :)

Is that a composite compressor housing for the turbo?

[@andrewwilson8317]

Very nice but pretty simple engine. Looks quite crude when compared to a modern sports bike engine but can't complain at the numbers,a massive turbo can make any engine go crazy! Can you just imagine it off boost? The turbo lag must be awful?

[@thebigmacd]

These engines did not build boost until around 7000 rpm. Search for "bmw f1 turbo dyno plot" in Google images and there is a dyno plot as first result. They don't even start the plot until 7000 rpm.

[@schwanzelstock1071]

Had to do at least 100,000 up to 115,000 km that way they could examine the block and be sure all the stretching already took place. So they got world champion once with blocks that did 100.000 km :-P

[@steenlassen5718]

The block is from a standard streetcar, belive it or not! But like Schwanzel Stock writes: They were rather "matured", so they were certain there was no stress in them.

[@paulweatherley3140]

[@keyboard101101]

You want an engine to make big power and be reliable. It’s Gonna have a Closed deck Iron Block, gear driven timing, and piston cooling jets. Lightweight should never be the focus on an Engine block it should be overbuilt, on the internals sure, lightweight forged pistons and rods.
