Scuderia Ferrari SF71H

A place to discuss the characteristics of the cars in Formula One, both current as well as historical. Laptimes, driver worshipping and team chatter do not belong here.

You have to deactivate the valves in the open position, otherwise you will have pumping losses. Imagine you deactivate the cylinder after the intake stroke, with all valves close, in the compression stroke you will have pumping losses. Next , in the what should have been a power stroke, the pressure (which is atmospheric pressure if is normally aspirated or maybe double if is turbo, multiply by the compression ratio) is too small to do meaningful work and compensate for the pumping loses.
That is because the crank shaft will spin faster then what the pressure in the deactivated cylinder can achieve. The piston is pull down by the inertia of the flywheel/other cylinder work faster than it is pushed by the pressure in the deactivated cylinder.
You've got that completely backwards.

I think Sebastian's special paddle determines the % split between MGUK and rear discs on the brake-by-wire strategy.

You think it works like it does in this thingy? Where the blue paddle toggles how much regen braking is active?

Possibly. He's definitely using during braking from the FP on-board cam, but I doubt it is F/R balance as you still see him reach with his left hand. So it is either a K/brakes % change, diff % change, or possibly waste gate override % for blowing.

Whatever it is, it puts something directly under the drivers analog control, and I call that a good thing.

It amazes me that they even bother to try stuff like that.

The slot on the bottom side of the mirror is almost to small to let air through..
It's hard to distinguish if they have two slots on the bottom, or is it just the internal mirror casing. Two slots have my vote. :) Their attention to details is ridiculous.

And they call it a stall. A STALL!

Vanja, how's the CFD simulation going with those extra details? :twisted: :twisted:

Single slot under mirror with a vertical stand splitting it in the middle, it looks to me.

If their hollow mirrors are there to energize the flow over the sidepods, it would make total sense to have some edges there to energize it even more.
