Here's an explanation of the exhaust solutions on formula1.com

I'm not too sure how having the exhausts right on the outside translates to blowing the starter hole.

the team have come up with two different exhaust solutions at the back. One is very traditional (inset) and blows directly towards the rear of the car.

By "traditional" they mean a compromise so that they can get some time on track to test other parts of the car.

Surely if they had another solution to test we would never have seen this "traditional" exhaust?

Im still unsure if I really know what you mean n smikle? What exactly does scarbs owe the forum?

Yeah.

And one thing actually, Scarbs have luxury (a well deserved one) to talk with the top folks in the paddock, be at the tests and accumulated a helluva knowledge over the years.

His contribution here often clarified a lot of controversial points.

Who is talking about contribution? or being close to the paddock? We all know who Scarbs is. Remember, I began reading on his site before any other site. Waaay back.

Scarbs, you are doing a very good task of gleaning and summarizing then spreading information. I am fully behind the spread of information. In fact you will be hard pressed to find a more proper f1 blog on the technical side of things. You have your site (ScarbsF1) and the F1.com site. It is better for you to have information on your site than not have it at all. (look at wretched auto sport asking for money!) Not everybody is going to glean through a forum looking for the latest info, so your site is actually a service. I will big you up anytime. I would link people to your site gladly (not from here though hehe). This is my genuine feelings. I don't care what anybody else wants to say.

You see, I have no agenda.

I suppose you know Keith Collantine?, he regularly mentions the "regular folks" in his pieces. Keith's site exemplifies that water can not only flow down the F1 media stream but that is can flow up the stream as well.

However, these meek and humble f1technical members say F1 technical don't need bigging up, but I'm not the owner so I am not going to say yes.


edit.. guess I am too late? posts edited?

Few pics of that possible exhaust:



Looks like there is a heat-protection coating as well as extensive heat signs.

There is a 'V' shape funnel that tapers inwards towards the starter hole.
The following image shows the funneling of the upper surface of the diffuser:

I think thats from the launch so its not really relevant,

Why? Do we know that the upper surface of the diffuser has changed much since the launch?
In any event the theory (not one I have invented) is that the slit exhaust blows the gases inwards and rearwards. If the gases are being aimed at the starter hole, how can this be done.......answer, possibily via the funnel if its still exists on the diffuser in its current guise.

[Owen.C93]

Those channels are still there I think, I just couldn't find a better picture of them than the launch spec car.

[OO7]

One disadvantage of the slit exhaust, is that its location could make it vunerable to damage during wheel to wheel battles.

[bogi]

This is undercut floor from mp4-24,they are using same thing probably with this U-bend exhaust.Exhaust mask this undercut zone.

my theory

Because the less conventional layout turns towards the centre. It's right there in the text you read at F1.com!

Pedro... Look at the post before yours.

Let's have our greatest minds analyse these two set ups please since we know they are definite now?
Let's have out greatest minds analyse the less conventional one please!

The conventional layout probably blows more exhaust gas to the starter motor hole than flat exhausts right on the very edge of the floor would. If I personally wanted to blow them through the starter hole I wouldn't have the exhausts where they currently are at any rate.

Besides, my post was more to incite discussion on how it works.

That article makes it sound like the sheet exhaust is some rigged up solution just so they could get in more laps, which is silly. We know that McLaren had multiple configurations to test. Perhaps they had heat problems with one or more of their test configurations, and perhaps that's the very reason they needed to run them on track to try.

Yeah I thought the same too but that's what F1.com says. Are they usually spot on?

How can those pics above with the supposed slit exhaust in front of the rear tyre blow the starter hole? Does the U-bend pipe bend inwards and there is a slit we cannot see? Or has the bonded section more exits than we can see?

[akshat21]

Personally, I don't think that even the F1's official site would be spot on, as no team will reveal their design secrets at the beginning of the season. I think what the site is doing is just using simple logic (coupled with aerodynamic know how) to present a probable solution to the U-Bend.
