Maybe we´ll see a RBR-type exhaust.

That i would belive. Including the tunnels.

I also believe this is what's needed on the mclaren. Red bull have it on the car now and they are the best at slow speed it seems now, Gary Anderson said after Valencia that the new exhaust will improve red bull at slow speed corners and judging by Valencia it has improved ten fold for them. Thing is now we've been to a high speed circuit and they won again.... Looking ominous really.

About the RRA, are the restrictions in place already?

On the 'new raised chassis' idea, isn't there a rule on homigated chassis now and has been for afew seasons? If so, how is it possible to bring a new chassis mid-season? Are there ways around it like any other rule?

Its understood to be a revised exhaust solution and it probably will be, so lets stop talking crap about the chassis. Im kinda glad its to do with rear bodywork/downforce because like i said before its the lack of rear grip thats not letting us keep up with the leaders and a lack of rear grip thats 'eating' the rear tyres

Yes and how do you gain rear grip,,,, Downforce at the rear, how do you gain that?,,,, more air to the rear of the car, how do you do that?,,,, high nose/ chassis change, the car all acts as one, so to gain more rear downforce you need more air to the rear of the car, which is why the nose is so important for rear downforce...

But how much higher is the nose on the raised chassis cars? Not that much.

My thoughts exactly, it can only be 50mm at the most, but saying that, F1 is about the smallest margins and 2 inch is a rather large margin.

Also to N12ck you are right, it all starts from the front, but mclaren cant change their front really, its too drastic of a change, just leave the chassis and improve the rear, like i said before, get a damn vented diffuser on the car like the best car on the grid has. Red Bull.

Also like i asked about 4 posts ago, isnt there a holmigated chassis rule? If so, why waste time developing a new chassis for mid-season and why waste our time talking about one if they cant bring it due to rules. There might be a way around the rule but that'd result in another ballsed up compromise.

its not about the height of the nose at the tip so much (you can make the height identical with a max height of 550mm) however its volume under the nose/tub, which when you raise the tub gets larger (as shown below), which means the higher tub can have more air flowing underneath it.



so thats more area underneath the nose, which means more air going to the rear of the car

They do vent the diffuser like red bull and every other team on the grid apart from MGP.

[Owen.C93]

New rear brake ducts. Looks to be larger opening between duct and tyre.

Further view which confirms inner opening. From @tgruener

[N12ck]

to show the area gained by a high nose, and why it gives more volume and air to the rear of the car here is an overlay on CAD,

[RicME85]

Do you really need to put copyright on those pics Nick?

I can understand the logic of changing the chassis but if they do, the car has to hit the track and be winning races straight away for it to be worthwhile surely?
Realistically can that happen....Im not so sure.

[McMrocks]

thanks a lot.
Does this increase the volume going under the floor?

[Owen.C93]

That's the idea.

[CjC]

@Owen.C93

I mean red bull have that rather large horizontal slot on the side pod running along the top of the floor, feeding air directly into the diffuser.

The picture in the link explains what I mean:

Also maybe because the conditions over the weekend were that bad mclaren didn't run all '7 or 8' updates because they defiantly wouldn't have been able to evaluate then. Johnaton Neale said they wouldn't be putting any 'risk' on the car so that potentially meant 5 or so parts were left off the ca? So basically that could mean at silverstone we near enough saw the same mclaren as to the one we saw in Valencia... The result would suggest that but I'm just speculating

We now have a quantitative measure for early discussions had around page 4 of this thread. Clearly Mr Anderson was correct about the limited potential for development of the 'pretty nose' at ~27 launch.

[CjC]

Yes and in his post silverstone report he says he's still sticking to his guns, he also got shot down by Ron Dennis early season, Ron was saying mclaren were the quickest, Ron wasn't wrong, nor was Mr. Anderson....

I wonder if Gary Anderson fancies a job at mclaren?
