The "Ultimate" engine : BMW Motorsport S70/2 V12

I have started this new thread to collect together all information/pics etc of the worlds "Ultimate" engine :- BMW Motorsports S70/2 V12

Hopefully if this thread generates enough content it will sit nicely in the "best of the threads" list :) (I thought a thread on this engine allready existed ? )

I,ll start with this excellent article from March 2004 ClassicCars magazine

Will add scan of front cover later.

Nice idea, Le Man! :thumbsup:

For me just one article is nice, and I wonder how many will be gathered here. Then again, knowing how much articles are out there on the car itself (and I don't think we're even close to half of those, in the various article threads we have), I'm sure many more will follow :-)

Hmm, I have a subfolder just for the F1 engine.... I'll have a look to see what I can dig up :)

Le Man, this is nice! :runaround:
Never know enough about this engine.


If someone see this one on EBAY, hihgly recomended to get:
Racecar Engineering Magazine from 1996 Vol 6 No 1 will tell something how everything get started. Full report of 1996 GTR with some detail images told also by Gordon Murray; differences and changes of 1995-1997 GTR's. Fantastic story, also included the engine/Gearbox story.!
Also full Gordon Murray interview.

Following on from Sami - here is something for you all

Yes, exactly this one!
There is one sentence on that page, which stoped me completely:

"the engine that won Le Mans 1995 was internally an untouched road car engine. Nothing was changed on it. It was re-mapped, but that was it".

:runaround:

Hey guys,

Does anyone have any magazine articles or books that discuss in detail, the air intake that mounts the engine?

Hey guys,

Does anyone have any magazine articles or books that discuss in detail, the air intake that mounts the engine?

No actual content on just the airbox alone, but the cutaway engine pic on page 104 of DA showing the airbox internals is self explanatory.

If you wish for a further detailed description of how the air travels through the roof intake and into the cylinders, plus the various components involved, feel free to ask.

Question:- name another car, other than the F1, which use,s its monocoque as an air filter housing?

Thanks for the reply. I'm OK with how the intake works, I just wondered about possible articles on it that may have discussed any detail about it. I was always interested in it because it's a unique air-intake and it looks very sharp when that hood is open, it's one of my favorite pieces of the F1.

As for the picture in DA of it's internal parts, I would need to see the picture elsewhere, maybe online somehow as my book and I are a distance apart for a while. Thanks Again!

Hey guys, this may seem like a weird request but I would like to change my background to some more "technical" looking pictures of the McLaren and thought it would be cool to have a high res engine shot as the background. Kinda like on page 96 or 101 of Driving Ambition. I have a couple of lower res shots that I can share. I think it might be really cool to have a shot of the engine straight on from the accessories side. I know I am asking a lot but I do think it would be cool. Thanks in advance!

I forgot I also have this one which makes a GREAT background for a smartphone or 7" tablet. Enjoy guys!

I've always liked this pic, and used it for my desktop background for a while :)

The shot on the dyno, is the best side-on pic I have seen :smokin:

This one?

There is also this one in side view

Maybe you like one of those:

Some of the best pictures yet! Thanks!

The ITB's (black) under and connected to the bottom of the air intake, do we know what metal they are made of, any facts about materials anywhere?

Those are awesome, THANKS! I really love the one showing the throttle linkage at the back of the engine.

Fairly sure those are ABS plastic. I've not had my fingers that deep into one but I'd be surprised if they weren't anyway.

Are you sure we are talking about the same parts? What I'm referring to connects to the engine where plastic would not hold up. I'm referring to the individual throttle bodies of the air intake; they plug into the top of the engine.

I'm talking about the parts these yellow arrows point to. I would put money on them being plastic.

http://i50.tinypic.com/mluns.jpg

ABS doesn't melt or deform under temperatures below 220F. It would be perfectly acceptable in that position under the air intake box. Every car I have ever owned had an ABS plastic intake manifold that bolted directly to the head, just above or next to the engine block.

On the F1 engine they have the benefit of being elevated quite far from the major areas of heat with the true throttle body inlets below them as a buffer from the engine.

Thanks for the detail regarding the ABS plastic, I wasn't familiar with it.

However, those pieces truly are metal, I had them in my hands, that's why I wanted to know what kind of metal they are.

Aluminum or magnesium would make the most sense if you are sure they were metal. Still a little odd to hear that. :confused:

The Ferrari F50 has a very similar intake design - those exact same parts are plastic and (except for being paired) look nearly identical. There's a thread on FChat with descriptions and photos:

Interesting, they look very much the same. I should have said the ones I held were from the intake of the test engine. Perhaps they used metal on that intake and ABS plastic on the final design, but who knows. I'm certain they were metal though. You could be right regarding the final version Erik.:)

Was this the piece you are referring to? Because the pipes on this one do appear to be metal as opposed to plastic.

On a non XP roadcar they are definitely plastic. Not physically checked a 95 or 96 GTR but presume they will be the same. a 97 might possibly be different but haven't got one next to me to check:wink:

Yes that's the one.

I am happy that you like them :smokin:

That airbox, looks like the very early type fitted to Edward test mule, interesting to see all the detail changes made to the production version. The carbon air boxes were not made by McLaren, they were made in Germany, by a contractor supplying BMW.

Erik would you be so kind to combine this thread to my Engine thread I started some time back. many thanks in advance.

since the engine thread has been combined here I thought i would share this picture for someone to use as a background, or just to droll over....

Is there a BMW logo on top ?

Yes, is the answer to your question.

At my place of work we had an S70 engine (from bmw lm car) on a stand as a display piece. I used to walk past it and wonder what I could put it in if it was up for grabs:iceslolan I thought an ultima or a cobra :grinyes:

As it turned out the guys from Munich asked for it back last year and I think it's the one next to the Long tail in the mobile tradition museum.

Even after I'd seen it every day for years I used to stop and stare everyday. The detail and engineering thought was incredible.
