McLaren MP4-26 Mercedes

Nice multi page speculation with no source whatsoever, apart from other forums.

Some people seem very sure of themselves.

The source that started the speculation is the AutoSport magazine. That's not to say the magazine is accurate either though.

I'd be amazed if that was declared legal, but then I'd also be pretty shocked if McLaren hadn't already cleared it with the FIA.

That was just a sketch to show what it "might" look like.

So would the exhausts seen infront of the rear wheels and the "octopus" system be different? I can't personally see how they would be linked.

[Just_a_fan]

So, from that drawing, would the beam wing be being blown? If so, I wonder how they hoped to get that through too. If they were blowing the wing, that would explain why they have the wing and crash structure linked so massively.

If they can get that lot to work it would be pretty cool.

Yet again McLaren try to roll the dice on something different and interesting. I like them for trying these things - I just wish they were allowed to use them. Much more clever engineering than just some tightly shaped sidepods...

It's infuriating that the FIA have banned Pyrosic for cost reasons, regardless of the material cost, if a manufacturer finds a clever way to use new materials and they come under the budget imposed on each team for the racing year then there should be no problem !!

It's probably been banned because some "other" teams have found out about the exhaust concept that McLaren are trying to run that relies on this material & have winged to the FIA about it !!!

I'm getting sick of this sport killing innovation !!!

I don't think so. It was long ago that the introduced (on cost grounds) the rule that the cars has to make of only certain materials. This excludes some expensive materials. It is not like FIA suddenly banned some material only because McLaren used it

Following your thinking.. why are we even hearing about this, and whys it affected their pace so recently?

IF the picture is not outdated look at these areas:

1.Red circle: exhaust pipe?
2.Lavender circle: lower wishbone overheated or debris?
3.Green circle: uprights endplates overheated or debris?
4.Blue circle: central floor cavity under the crash structure?

I think the whole damn rear floor diffuser is made out of pyrosic. from the begining the colour has always looked "off" to me. Too brownish looking.

You can see the ceramic box clearly for real. I was always suspicious of it!

[wesley123]

Now you mention it, i'm in on that one.

The end plate is just plain black, the diffuser got much more of a greyish look, might as well be a different Carbon pattern though, but its colour etc. it doesnt seem like just carbon.

All this exhaust talk got me looking at the regs: The regs state: "5.6 Exhaust systems: Engine exhaust systems may incorporate no more than two exits."
Pretty open really and no need to find a loophole.
So, my thoughts are, in the octopus/moose box, if McLaren mix exhaust gases (via 2 engine exits) with fresh air from some ducting (sidepods maybe) then the exhausts have effectively ended. In my car, the exhaust stops being an exhaust when the gases meet fresh air?

Correct me if I'm wrong! I'm not an expert. It's just an opinion as I like to think I'm pretty good when it comes to problem solving and thinking out of the box.
Thoughts please......

Below is the quote from the regulations. Very few things have been changed from last and previous years. So, yes, this has been in the regulation for ages.

Further there is a description of what PyroSic is. You judge if it is in the regulations...

Advanced glass-ceramic matrix composites with user-friendly processing
PyroSic


After 10 years of development, Pyromeral Systems has introduced an entirely new generation of materials that finally brings the advantages of composites to the world of high temperatures. With this technology, it is now possible to design and manufacture lightweight composite parts used at high temperatures that not only provide an excellent level of thermo-mechanical performance, but also remain easy and affordable to produce.

These new composite materials, marketed under the PyroSic® and PyroKarb™ names, are based on proprietary glass-ceramic matrix systems reinforced with silicon carbide or carbon fibers. Thanks to the use of advanced inorganic polymers, they are processed at low temperatures with the same techniques and tooling as those used for conventional carbon-fiber reinforced plastics (CFRP). Yet, they also offer a much improved resistance to heat and fire, as they retain good mechanical properties at temperatures for which CFRP cannot even be considered (typically, up to 1000°C/1800°F).

I Believe that if the exhaust exits ends right before the entrance to this octopus box so there is a small clearing between the two then it would be legal? The exhausts does not need to go directly into the box. They can just blow into the entrance holes ...

this was also my thought, but in this came the efficiency of the system will be small, no? I am by no means an expect in that though
