if you really think mclaren struggled last year because they choose to focus on the f-duct (something which gave upto 0.5 sec) then your completely wrong. The problem was the basic fundamentals so dont talk rubbish about the testing.segedunum wrote:Funnily enough this nonsense happened last year, I turned out to be right and it all went a bit quiet.....
McLaren wasted a great deal of winter testing last year trying to get their F-duct to work, but when it came to the crunch they didn't have the raw downforce or cornering speed of other teams so when they then acquired F-ducts McLaren had nothing left and had to start doing the work they should have done in the winter. When you start testing three completely different ways of doing the same thing in a period of practical testing where you have no time then you're wasting it. Everyone bleated to me at the time that McLaren had the resources to do that as well. They clearly didn't.
Do one thing and do it well and make sure it adds real speed.
You aren't testing a single philosophy over and over. You decide on a direction that you're going to go in via simulation and wind tunnel testing that you're sure of and you then refine that in practical tests and make sure the practice matches the theory. Endless live testing where you throw resources at a problem, shift things in a completely different direction and ship things out endlessly from the factory over several weeks has long gone. I take it there was a reason why McLaren turned up late to these tests?
That is definitely not an exhaust in the splitter. Routing an exhaust there would be silly and impractical.

Why am I not surprised? If that's the case then they've got their work cut out and have more to worry about than exhausts.
Hi and welcome JB !JB2011 wrote:Hi, new member here. I've been reading this thread since Valencia and it's very interesting, so thank you. I've just signed up because I've had a thought about the McLaren exhaust system based on this photo.
I was wondering if anyone thinks it's possible to create suction using the exhaust gases by flowing them across a slot in the floor? Sort of like a fan car? (do the rules allow a hole in the floor?) Sometimes vacuum cleaners have slots in the lances and if you put your hand over it, it gets sucked in. Would this create an advantage without a much lower floor? Sorry I'm not an engineer, I'm just really interested in how stuff works.
My theory is that the U bend in the pipes also angles them downwards slightly towards the bottom of the car. On the left, the shape of the floor seems to follow the shape of the pipe. If the exhaust gases are then flowed over slots in the floor, could the whole lot then be routed up to exit the car through the cooling duct in the middle/rear of the engine cover and flow into the lower portion of the rear wing? We've seen a lot of changes to this cooling duct so it does appear to be linked to the system.
As the rear of some of the other cars is smaller compared to the McLaren, maybe they have room for this arrangement under their larger engine cover.

I'm not suggesting anything untoward, I am just curious where these rumors came from. This is something that you could only see in telemetry decisively.Pup wrote:Someone he met in the Land of Swirly Twirly Rumors told him.Giblet wrote:Source?
I remember Button being quoted saying something to the effect that the car balance wasn't to his liking, during one of the testing days where it was windy.Giblet wrote:Source?segedunum wrote:Rumours swirled around that Jerez test that the car is very sensitive to changes in wind direction with some of the heavy winds there, and hence probably air direction in yaw as well.

I believe it was someone called "Segedunum" that started that rumour...Pup wrote:Someone he met in the Land of Swirly Twirly Rumors told him.Giblet wrote:Source?

I think it was in an Autosport interview, but there you go.
) you can see the bulk caused by the engine alone and it looks definitively FAT. Looked the same last year, but it didn't seem too bad when viewed with the sidepods together.
Funnily enough, I was watching a program on BBC on the A380. (Richard Hammond's engineering connections)JB2011 wrote:Hi, new member here.

Ferrari may beat them this year, but christ is there car dull and uninspiring. It's the same car as last year, tweaked a little bit, with some ideas copied from others. The only innovative thing they've done is move the rear dampers forward a bit. And Red Bull aren't much better.
Besides the 5cm perimeter of the diffuser I believe the only available hole in the floor is the starter.JB2011 wrote:
