McLaren MCL33

[Coefficient]

I think the funky stuff will start to appear on the MCL33 now they've base lined it and it appears fundamentally decent.

New turning vane just below mirror on chassis ??

No, reflection of the bottom of the sidepod inlet in combination with shadow in that inlet.

Gurney flap on the cooling exits: Not sure if desperate or genius.

Normal, many teams have run that for many years.

Wish I could get an HD shot of this! You can see the vortex forming from the slot gap on the floor, and the spray from the y250 vortex area is clearly going through the bargeboard then channeled to the outside of the sidepod endplate. Look at how the spray of the front wheels feeds this y250 spray, particularly the wheel hubs. Then the complete lack of spray near the front wing end plates.

@godlameroso:

That should be close enough. From page 23.

I hope after this photo we will stop writing and thinkig that side-pod deflectors are there to pick up front tyre wake and magically make it a good-boy laminar flow. At least people here, Gary A sure as hell won't stop with that.

Thanks, that was from yesterday, I was looking for something from this morning.

Eric Boullier explaining the exhaust bolt problem (from Autosport):

"It's a stupid bolt that broke in the exhaust," said racing director Eric Boullier of the first issue.

"So it was a £2 problem which cost us a lot of track time, because everything was burned after in the back of the car, so we had to rebuild the gearbox and the back end.

"Nothing else than this. It didn't cost us much to revise the design, it's more about the track time we lost. As you can see the design is still the same and the car is still running."

Regarding Thursday's problem, he added: "Cooling is the first matter that every team is managing in the first week of testing.

"In a case where you have a new engine partner, you might have some sort of heat soak pocket in the car.

"We can see on the bodywork there are a couple of stripes, but this is just because we have to make sure there are some proper heat shields in place, consider all the heat soak pockets, and make sure we can modify and change the cooling inside the bodywork."

I once posted the question as to wether how these slots in the floor are legal. There are no small cuts which would make the contour one homogenous line. So how it is legal?

My only thought is that they AREN'T legal today, but McLaren don't want to show other teams how to make them legal before Australia.

Everyone already knows how to make them legal, it's simply making a cut from the hole to the floors edge.

Except that they don't - you can't "simply" make a cut for such large slots, since it'll cause the floor to flex too much.

I have no idea what you are seeing, all I see is tire wake being pushed aside, which is the result of what you are talking about. People 'want' to see these vortices because they are so exciting but conditions must be quite perfect for them to be visible. Is this what you are seeing?

I don't see the issue:



And some tactically placed support

The cooling openings near the head of the driver are new for today I guess

[the EDGE]

can the floor slot cut to the edge be hidden under the bargeboard area in the front outside corner?

Any chance they are actually building any "hydrodynamic" devices into these cars for wet weather conditions? A win is a win even if it comes in the rain. .........."Dig Deeper, deeper till we get to China, never stop... ever! "
