McLaren MCL36

Yes, of course, that is the initial solution. However, that solution costs decent performance. You want to have a long low zone in those tunnels so you can maximize the area where low pressure peaks.

I believe one of the biggest contributions to Mclaren’s lack of porpoising is underfloor profile. All the teams have double kick diffuser, but the first kick-up of MCL36 solution has very conservative angle (seen above). So it provides sufficient suction, but doesn’t produce severe adverse pressure gradients getting closer to the ground. Of course, other bits on the floor edge are fine tuning devices

One gets the impression that everything was done in haste. It seems that this decision is also temporary, or there will be several such decisions tomorrow in training.

lol i think its fair to say mclaren got their cooling calculations horible wrong for this track, everything is basicly twice or more, the size compared to last week

The calculations about the brakes were probably all ok but i think that they were cought out by the increase of the pace of the car. The cars are aparently faster than everyone have thought.

So what I can interpret from this is, the silicone was used to absorb the heat that was leaking from the sides, this solution shrouds that area to reduce or stop leakage into the cake tins, anyway that's a pretty significant alteration.

I am guessing this is a way over spec part such that they dont even risk dnf'ing and can do race sims properly, I suspect we will get a more robust version of the testing spec parts later in the season.

yep I agree, sucks though quite a hinderance, development and time that could of been used elsewhere.

Although to say the least these are comparable in size to other team cooling ducts.

Totally agree that's a hastily engineered solution and I wonder if they will try a couple and then optimise from there.

Interesting thoughts, I think it's also the way they are using a bit of rake and vortex generation at the side pod and floor edge to seal the floor.

Shouldn't that be expected for a short turnaround?
