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.

Awesome video of one of the greatest F1 engines ever developed. The smile on Mr. Rosche's face says it all!

[@blackbeard9958]

Am i the only one who finds these videos of engines being built oddly satisfying?

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 Artificial intelligence and robots are taking this away these skills and now man is a component that is soon to be superceded.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

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

I love that these guys are in Germany and Credence Clearwater Revival was on the radio! 👍🏻👍🏻👍🏻

[@TheRjjrjjr]

It's so nice to watch these old craftsmen build this beautiful engine.

[@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!!!!!!!!!!!!!!!!!!

[@bujfvjg7222]

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.

[@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

[@autotalon]

Wow that carbon fiber compressor housing is pretty sweet

[@richieac1000]

To me this was the pinnacle of F1 😎

[@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.

[@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,

[@jackzac]

the size of that turbo !!

[@FrankValchiria]

when i saw the turbo , than i understood.

[@Big2009Gee]

FrankValchiria I know what you mean old turbos are so inefficient they have to be huge.

[@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.

[@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]

[@lucagoldoni2413]

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)

[@GB-vn1tf]

I believe you're correct. I know its before M3. Just the block though. Dry sump and different head.

[@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

[@philippbecker5392]

Great Video! Nice to see Nocken Paule 👍

[@joshgreaves9934]

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.

[@ar_pe4012]

As it is „basically“ an M10 engine I am very proud that my 1502 is at least some kind of an F1 car! :D

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.

[@ericnickel3280]

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.

[@brunomanco7529]

So the throttle body is placed before the Turbo ?? *interesting*
