If they are making "inverted U pods" it's a brilliant execution of something that I've been considering for the last two years. Audi did this with their R15, and their DTM cars, it's actually odd to see F1 take this long to run with the concept. As usual though it appears RB was 'at that party' already. In fact it's the through body aero that is essentially the last place to get any decent aero gain seeing as the lack of regulations pertaining to most of the sidepod area.

How do you mean 'as usual red bull are already at the party'?

I wouldn't be surprised though, notice how red bull as usuall keep quiet about development, Newey will put something on the car Friday, storm 2 pole by a ridiculous amount and everyone will be saying 'mclaren have a new what?'.....

So far the simulations are showing quite turbulent flow through the tunnel, will publish images later also something else thats interesting is that the flow goes through the tunnels, follows the cokebottle and then rapidly changes direction towards the outer edges of the diffuer, slightly confusing

edit: the flow slows down through the tunnel

Are you doing this having an Red Bull duct at the end of the tunnel under or at the exhaust, so the flow goes thru the tunnel then into a duct ?

no upside down L pod design as scarbs suggested,

Yeah but i think even that has to lead into something, cant just have alot of air going thru the sidepod and just exit, i believe if they do make a tunnel it will lead air from the beginning of the sidepod into a duct or ducts at the end of the sidepod, at the exhaust or under.

Would this not be the expected result? The sides of the tunnel will create a large surface area which will create a large amount of boundary layer interaction slowing the air down significantly.

whats interesting is it follows the coke bottle then rapidly changes direction towards the outer edges of the diffuser, exactley where you want the exhaust gases

Under normal circumstances with 2012 exhaust positioning that would push exhaust gases away (probably up) and would be a bad idea. But they can combine it with double floor Red Bull trick, and keep tunneled air under the floor separated from exhaust.

I'm more interested in another option. A variation of regular 2011 U sidepods used to channel air over exhaust position to push exhaust gasses down over diffuser.

Possibly my tunnel isnt long enough, I will try a longer tunnel

Plz try if you can to add a duct similair to the red bull one that leads the air to the motor starter hole, after the tunnel or inside the tunnel at the end.

Edit: If its hard to understand or visulize what i mean, i think of the U-Tunnel as it not having an open end, that it feeds air into a duct that starts inside the tunnel at the very end of what would be the wall of the cutout under the mclaren exhaust on the current car setup, and that duct would then be above the floor at the end much like RB has and lead to the start motor hole.

Do you understand what i mean by that ?

I will do tomorrow, but at the moment, I am getting my head round the current solution, I am trying to do all this before we see McLaren's new bodywork so we can know its effects without guessing, 'it may do this or that'

[FrukostScones]

So the "no sidepods as such" car arrives for the German GP? ..... maybe the change is only so minor that you will barely notice it (like with Mercedes W03)..... But according to Andrew Benson of BBC Martin Whitmarsh said they will be "quite different" .....hoolahoop

I've been wondering why teams haven't done something like this before. However, here it seems is the answer:

Any vertical cross section of bodywork normal to the car centre line situated in the volumes defined below must form one tangent continuous curve on its external surface. This tangent continuous curve may not contain any radius less than 75mm:

a) The volume between 50mm forward of the rear wheel centre line and 300mm rearward of the rear face of the cockpit entry template, which is more than 25mm from the car centre line and more than 100mm above the reference plane.
b) The volume between 300mm rearward of the rear face of the cockpit entry template and the rear face of the cockpit entry template, which is more than 125mm from the car centre line and more than 100mm above the reference plane.

Since I think a fully enclosed tunnel's sides count as external surfaces, a tunnel like this is limited to 50mm in height - surely too small to be effective as Red Bull found with their V1 and V2 tunnels.

It could be done, sure, but it would not be effective in my opinion.

The shape will revert to something far more like the Red Bull or Ferrari I think. It is more likely to be the Red Bull because of the Ferrari's odd radiator layout etc. which has all been done with their exhaust in mind.

Well, it's still guessing, as we don't know what the bodywork is

It could just be a massive repackaging for small pods for all we know atm

true but we can know the effects of the upside down L pods, so everyone is happy!
