Ferrari F2012

[Forza]

I agree with godlameroso. Brake duct development or air ducts (as Mclaren refers to their solution) is instrumental area in order to stabilize/redirect the flow around the wheels / producing df.

I tried to find some pics of rear brake ducts.

Great picture, I´m always interested in the screens that we can see into garages and pitwall.

What does mean those numbers that appears in this picture?

Thanks!

Explanation from Brian Jee (ex electronics engineer).

Those are all channels monitoring amperage and voltage outputs/demands from the McLaren TAG-310 Powertrain Control Unit. We see the calibrated output of both front & rear ride height lasers and their supply voltages. Current of both fuel lift pumps. Lift scavenge pumps don’t need to run continuous, so we see duty cycle as well. 7A02, 7A03, 7A01 are wired pinouts on the PCU. Likewise all the HSD70* are “high side drivers” addressed from the PCU. There’s 4 channels, each with 2 control strategies.

what i can see from the photos below is what i suspected from the beginning....
Ferrari was using the curly piece on the footplate earlier this season, its the same curly part that can be seen below:


The photo above is a photo from Korea...
I remember they removed the curly part at a point through the season...i can't remember when..maybe someone does remember...

As we can see on the photo from Japan below the curly part is removed and istead there is just a reshaped footplate...


Ferrari have reverted to some older solutions this weekend with the diffuser footplate and the vortex generators below the mirrors....they probably realized that some updates didn't work and are now reverting back to older parts...

So with the new fin on the front brake ducts, the vortex generators below the mirrors and the diffuser footplate, we have 3 updates....what's the 4th one?


EDIT: good improvement from Ferrari P4 just 0.3 s behind

[jonaliew]

Could it be the RW? Did Alonso run the new one for P3?

Would you run run DA sensors from the powertrain control unit? Or display those on the same screen? Sometimes Formula 1 does confuse me .
The duty cycle of the pumps isn´t this meant to be a PWM signal used to adjust the flow ?

Amouzouris may have written the epitaph for Ferrari's season:

If true (and I would not be surprised) that says a great deal. Who gets fired?

But maybe we should try to be kind and suggest that a basically inferior design has reached its peak and can't be developed to match inherently better designs(?)

Heard there's a major upgrade coming for India- any idea what's included?

Heard there's a major upgrade coming for India- any idea what's included?

Its all rumour but three or more come to my mind...however Pat Fry did state "Major upgrade for India" which could mean more?

My five guesses:

- New Front wing (that actually works)
- New Stalled Rear wing? (DRD)
- Sidepod profile change/possible airflow conditioner
- New slotted floor (with slit/cut)
- Pelican beak under the FW? (Similar to Lotus/RBR).

These are just big stabs in the dark abyss!

There's been rumours of some 'big update' for several races now that's come to very little, and I suppose there has to be with Domenicali being summoned back to Maranello every five minutes.

Given the hit and miss nature of everything they've put on the car so far (rear wings on, rear wings off, front wings on, front wings off) I wouldn't get too excited. Like Lotus it's all too little too late really. You need several races to get anything you put on really working in the way you imagined it would.

Thank you amouzouris. Quite informative and worth a +1. I was surprised that Ferrari's "upgrades" were basically reverting back to earlier aero details. Imo it suggests that the pace at Korea was more due to the track really suited to the car than any particular development work they did.

Indeed...Alonso also said that they have pretty much the same car as in Suzuka... Logic suggests that there are a couple of updates in the pipeline for months...new slotted front wing endplate is one we have seen tested....but there are probably other updates as well which we haven't yet seen and are being tested for quite sometime now because of all the wind tunnel conundrum...these parts are/have probably be tested in Cologne and will appear sooner or later...India as it is being suggested

I read on another forum that in korea massa has used a new engine, while alonso had an used one.
Can anyone confirm /rectify this?
I think that massa was running with a lower downforce level compared to alonso.
Strange to see that, as last year, it is korea where massa performs better in comparison with alonso. What do kprea and turkey circuit have in common?

[diffuser]

I've been expecting something big to come out of the young drivers test. I figured they would have collected enough information to confirm or deny what they've been seeing in the tunnel. So I wouldn't be surprised to see a large update in India.


Its getting late into the season. It now or never. Otherwise, we'll just be praying for rain!

[raymondu999]

What do kprea and turkey circuit have in common?

Cunterclockwise, and a series of switch back corners (4-5-6 in Korea and rhe last sector, 3-4-5 in Turkey and 12-13-14)
