Mercedes AMG F1 W03

You most certainly do want to blow the exhaust into the diffuser.

You want to blow the exhaust along the side of the diffuser. You explained why in your own post.

Right, if the rules allowed, you would blow into the diffuser. They didn't, so teams blew the edges. Both are of benefit.

It is burning a lot just above the floor too. Definitely nothing to do with fumes apart perhaps that small bit on on top. It is the manifold that heats up the bodywork.

Check the image with increased gamma

I don't see any distortion which is good. The Ferrari looked like it was either distorting or paint was bubbling.

Interesting as the car is rounding the track like a clock very reliably. Perhaps they knew this was coming and are not too concerned at the moment?

Yeah, I don't see it as an issue. If you look at the launch car for the photo op, it had even less heat shielding, I'm guessing to show off the sponsors.

Roll hoop intake flo-vis test looks familiar...
...Mcl took a while to get it working from memory.

I hope they just change the paint to something more heat resistant or cover everything behind the exhaust in the black heat shielding...
Then hopefully the hole "burned bodywork" chitchat is over...
As long as there are no holes or gills in it its sufficient for them.

Anyway, good effort to do so much laps today and according to MSC it feels way better than last year.

Regarding the tire: normally the front left is the tire with most stress on this track, so that thing on the right is probably pickup rubber, too much camber or too low pressure (so that the center of the tire patch is not really touching the ground), Pirelli production failure or MS ruined this one on a curb

Mercedes had a similar intake last year already, I think introduced somewhere midseason...

there is NO burning/overheating problem. these are the effects of tighter rear packaging. you have to decide between tighter and relaxer packaging. you have to compromise it.

You are right on money here
i think they have reduced the tire pressure on the right front purposly...cause there are alot of right hand corner so that will aid in turn in

This year's Ferrari? If so could you provide a pic? I fear that again cooling is going to be a problem for Mercedes. On the other hand, they were able to complete 127 laps without issues so I guess it is not so important at the moment. What will happen though if Australia and Malaysia are way hotter than Barcelona is now?

[marcush.]

heat affected zone is really a matter of distance to the heat source.a cf part is maybe a bit more suited to temps over 80°C than a conventional paintcoat.
So it is not really a surprise to see paint in trouble in that area.Sure some areas look like having suffered from radiant heat from the exhaust pipes...So they have not yet covered the pipes as is surely state of the art now?or it´s just damn close in that area.
Again the paint burns do not indicate the car is running too hot ,but it says some parts get cooked by other parts too close.
When the car is marginal on cooling you have to take it of the boil=drive slower to make it live as otherwise the temps will soar.
To me Schumacher showed today the car is ok on the cooling side ,at least for the current climate.

Would it be possible to use radiator intake air and channel it through the coke bottle,then distribute the air thru and over diffuser. I hope this image demonstrates what I'm writing about.

Would it make sense to do that?

I don't know, maybe if we see the whole rear covered in black heat-resistant material we will know, but the problem is that if you look at the pic posted on the previous page even that turns brown-ish at places so maybe it is not enough? The real questions are: a)is it serious enough to make them change the beautiful sidepod design? b)can they fix it back at the factory during the 6 day break until the second Barcelona test?

[dren]

It's still a mystery where that top mini diffuser is getting its air from. It is probably coming up from the starter hole to make a semi double diffuser. I think the exhaust is expanding and covering the entire top of the diffuser, sort of like their side exit exhaust did last year. I expect a few more solutions to be tried out at the next test.

I think that is a simple fix with materials. Last year they had issues with the first blown diffuser delaminating from the heat which was caused be the materials they used.
