F1 1986: Assembling a Ford Cosworth TEC (GBA) V6 Turbo Formula 1 engine

[moondog203]

And what extra damage could be caused to the block from slooowwwwly lowering it in to slowly lowering it in?

[parkwood76]

How fantastic to see my hero, the late Keith Duckworth, at his drawing board talking about something that he has designed. Rest in peace Keith, we miss you!

[loowww1]

this engine will be a desaster..... sadely

[aljobaris]

@loowww1 Your spelling is a bigger disaster

[loowww1]

@aljobaris because any ford turbo f1 motor will be a disaster, it's not, critical bit history

[loowww1]

@aljobaris sorry? i'm not english so .... well, this engine (the turbo cosworth) would never do a result. That's it.

[cptkorean]

lol is that michael caine commenting? AWESOME

[designer1240]

Everything was drawn by hand @ a drafting table.  Crazy good!

[rockitman150]

A DTM OPEL Calibra engine no?.

[bizling]

This engine ended up in the Benettons right?

At uni one of the lectures worked at Cosworth for 21 years, in an engine seminar he said this engine made just over 2000hp @ 4 Bar (Absoute), estimates then suggested 3600hp was attainable @ 8 Bar (Absolute).

6:07 "For simplicity, oil is forced through external steel tubes" the main reason being to remove the need for a head gasket. If you notice at 6:15 there is also no block to head cooling water path. This results in a cooler head for more power as well as a more rigid block. If there is no gasket...it cannot fail. The 'Wills' firing ring is all thats needed. These engines would be more able to withstand the odd bit of detonation, far more than a conventional block anyway. Great vids!

[Marillionado]

I had this o VHS and been loking for it for ages. Sorry you missed the start were they tested the 4 cylinder engine in an effort to replicate what BMW was doing at the time.

Thanks a LOT for posting this.

[Shazee083]

i want those blueprints

[ouralphe]

2013 F1 TURBO 650 CV MUHAHAHAHAHH! F1 IS DEAD......

[Marillionado]

@ouralphe I for one bet it will be the best thing in years for F1

[flipsidedogchop]

welcome back the Turbos for 2013!

[myrx2]

@flipsidedogchop shit yeah cant wait. pitty there going to be half the power then what they had in the 80s. "only" 600-700hp

[MegaAmer90]

@flipsidedogchop but 4 cylinder n 14000 rpm only...

[charade993]

@flipsidedogchop yup! think about it, turbo-charged small volume 4-pots. The technology can shift straight into production car engines! nice.

[xsilversportx]

@flipsidedogchop with 4 cylinders and only 1600ccm :/

[guitarstar12]

@xsilversportx Well in the 80s, they were only 1500cc 4 cyls and some of those made over 1300hp in qualifying. =) future's looking bright for F1. hahaha (yeah right)

[66606cl66]

@guitarstar12 those engines mainly got that power from running 85% toluene fuel, they tended to explode after 1 qualifying lap if i remember :L

[flipsidedogchop]

@xsilversportx remember the most powerful engine in F1 was a 1497cc 4 cylinder by BMW!

[Gostek166]

@flipsidedogchop 2014

[flipsidedogchop]

@Gostek166 9 months ago when i wrote that, it was supposed to be 2013

[GeraArg]

Thanks for sharing!!!!!! :)

The engine was actually the TH2's problem in 1986. Compared to the BMW's, Renault's, Honda's, Ferrari's & TAG turbo engines, the Ford V6 turbo simply didn't have enough power.Both Alan Jones & Patrick Tambay said it was a shame as the chassis was just about perfect.

[flipsidedogchop]

@Holden308 maybe they should have used a holden

[sookster54]

Interesting documentation on some of the best racing engines in history.

[marek0086]

"spreads the block by a FEW MILLIMETERS"..... bullshit.... more like a few HUNDREDTHS of A millimeter !!

[spiritcrusher923]

@marek0086 or less 

[Ropponmatsu2]

@marek0086 - Not quite true actually. Remember that the engine is not only a stressed component, in that it has got to be strong enough to carry vehicle loads, but also that as it operates it gets hot. It expands as a result. You can probably bend it by a "few millimeters" because that is EASILY what the bottom of the engine will experience as it operates.

[marek0086]

@Ropponmatsu2~ no, you dont know what you're talking about.

[Ropponmatsu2]

@marek0086 Keith Duckworth - "God" - As he was referred to - Is talking about the head bolts at the end, he SAYS how flexible the block is. The bolts run all the way down into the block in order to provide strength where the gas pressure is highest...The rest of the engine is very lightly built. One thing that he doesn't mention is the TEC has NO head gasket. The liners are made of a material called Nikasil, and they end at the little black rings seen on top of the cylinders.

So....Yes I do.

[marek0086]

@Ropponmatsu2~ Now u start talking about some other shit?!

I was talking about your PREVIOUS comment!!

[charade993]

@Ropponmatsu2

You cant 'make' a liner from nikasil, its a superficial coating which is normaly applied to aluminium. i would more likely believe these liners were steel for strength though. it would be pointless putting a aluminium liner in an alloy block or they would have just machined the bores into the block and Nikasil coated them...but they didnt. im with marek0086, a few thou at the most. Beautiful castings though!

[charade993]

@Ropponmatsu2 if the 'bottom' of the engine was to take even close to 1 or 2mm flex then the crank journals would run out of line and the mains would bind almost instantly (and spectacularly) once that bearing cap is on and torqued down however, it'll brace together and theres no way its gonna move!

[Ropponmatsu2]

@charade993 The liners are steel, it turns out, from "The 1000Bhp Grand Prix cars" which covers this engine.

If you tried to drive one of these engines from cold, you'd destroy it, for your reason, but as it gets hot, the block expands and it tensions itself "correctly," because it is bolted to the fuel tank/chassis and the gearbox. Here it is flexible, but in the car it is a loaded structure: It expands to the "correct" shape and lets you transmit loads through it, when at full power.

[charade993]

@Ropponmatsu2 Its only flexible because the bearing cap is not clamped down at that point.Once its torqued down its solid,loaded structure or not.I dont understand your argument. Either its flexible because its cold or its flexible when its warmed up? what exactly are you trying to tell me? go back and read what you wrote.Engines dont tension themselves hot. As an engine heats the stresses are evened out over all the components it shouldnt exert forces or it would crack. I think your confused.

[Ropponmatsu2]

@charade993 The casting IS capable of being spread by a few millimeters, to add the caps. That was my original posting.

Metals expand if heated...But think of it like this: The whole engine block gets physically slightly larger if hot. Hence: Engine manifold bolts have minimum torque settings. The other components expand and tighten even further, as the bolts are made of a metal that does not expand much (this eliminates the gasket) and the block can be thin/flexible but is stiff when heated.

[charade993]

@Ropponmatsu2 Dont believe everything you read on the internet ;)

[marek0086]

@Ropponmatsu2~ No its NOT capable!.... the block would BREAK in half before the main-cap-provisions could be "bent" open a few millimeters!

[jobjob76]

@marek0086 LOL true if it spread by a few millimetres it would crack in half

[drdoom06]

turbo turbo!

[Soundgarden1009]

yeah thatd be nice

[chrismcdc2]

Do you have any more clips of this documentary?? The earlier parts testing the unsuccessful 4cyl engine perhaps?
