Scuderia Ferrari SF90

This was probably mentioned before, but could the stacked wastegate pipes be an attempt to blow the exhaust gases as close as possible to the rear wing in order to create downforce?

[PhillipM]

It seems to be a strange philosophy moving stuff down from the engine cover to the sidepods - and I know a lot of you are saying to clean up the airflow to the new rear wing - but the taller, wider rear wings this year should be *less* affected by airflow from the engine cover area, not more.
That's why everyone else has moved more cooling up there out of the sidepods.

I can only think that Ferrari had a lot more weight up there last year than some other cars, and that was causing their issues with tyres at some circuits, so maybe they've gone for lower CoG - they still have less sidepod area when you consider the loss of the top inlets.
They have gone to some effort to clean up the rear though, the sidepods are tighter there, McL style wishbones, etc - so maybe they managed to get a good link between the diffuser and wing with the exhaust stacks or some other trick people have missed and are driving the wing harder than most to keep the wing and diffuser in synergy.
If so we'll find out because they won't be able to reduce wing levels much for low downforce circuits, and if not it was just CoG related.

Vanja! Where have you been? I missed your very interesting aerodynamic analyses. Welcome back.

Cheers, mate. Lot of work in the past few months, not over yet. I'll try to be more active, but can't promise anything.

Do we have any better photo of barge boards? They've done a lot to hide them with bad lighting.

Good news, mate! Will look for your comments. Good luck with your work. And now back to topic.

Is it me, or does the wheelbase look a touch shorter?

I felt that way too; also lots of rake - let’s see if they run it that way on track.

yes, the car has clearly more rake than in 2018. It seems that other cars have choosen a different path.

[Mr.G]

Just will amateur guess - lot of things indicates that they are trying to run the RW pretty hard:

- reduced air intake (to allow lot of air flow for the RW)
- reinforced DRS actuator (if the RW works harder, open an hold opened the flap will be harder too)
- "double barel" waste gate (attempt for energizing the airflow underneath the RW?)
- may be some FW cooperation?

I'm not sure I did it correctly, photos were taken at different angles a bit. It seems wheelbase shorter than SF70h Can anyone make a comparison too? https://pp.userapi.com/c849024/v8490241 ... kMXSlk.jpg

The different angles throws this comparison off. The longer wheelbase was one of SF-71's strengths so I doubt they changed that. The perspective creates the illusion of it being different. Plus the different liveries also plays a part in tricking ones eyes to seeing lengths shorter or longer.

Based on what I have seen so far, my assumption is that they aren't able to seal the floor as well as last year, and have lost some floor/diffuser generated down force. Thus to make up from this they are trying to work the new rear wing harder.

We won't know that for sure till we have seen it running on track.

I think you're right, Giorgio Piola and Franco Nugnes wrote about increasing wheelbase for 25mm

Cant remember if blown axles are forbbiden now.

Yup, blown axles are banned now.

They can still vent out through the face of the brake shroud, and thus out of the rim face i believe...

everyone will be trying what Merc was doing last year!

[Redragon]

What feels odd is after last years mirrors which were at the presentation and Redbull copying the concept this year they don't have them on this year presentation. So they might have something even more innovative on that area?

[Cedo]

Why are the cooling brakes holes so big? Would they try to blow some air through?[https://images.spot.im/image/upload/q_7 ... d7ac0ca302

Wouldn’t going such a radical way by maximizing airflow to RW because of the disability of sealing the floor and diffuser mean that they wouldn’t be able to do any upgrades at all on floor and diffuser? I think they would have even changed the concept to generate floor and diffuser downforce instead of compensating it in such a way.
