He said "elongated sidepod INLETS" not the complete sidepod.
In 2022 frontal area was bigger and front undercut of Ferrari was surely generating more stagnation than RB18. This year, launch SF-23 had very similar differences compared to RB19, so even if they improved this area in Ferrari the relative drag difference in that specific area remained in favour of RB since they also improved. Now with more undercut, SF23 evo (as Italians call it) seems to be even lower on drag than launch spec car and there is clearly room to further improve.
I don't think ride height is a problem any more, Charles car was at the limit for floor thickness at the end of the race as reported here: https://formu1a.uno/retroscena-ferrari- ... del-fondo/Vanja #66 wrote: ↑04 Jul 2023, 19:35I think they will be better off if they stick to their own floor development path. I believe they have a lot of room for improvement in various areas of the floor, but need to work further on suspension to keep it lower at the start of the race. Another point too - should they choose to go with elongated sidepod inlets like RB (a path they seem to have now taken) and move the SIS tube to the floor, they will reduce the chassis drag a bit. This will allow them to run more wing(s) and end up with about the same drag as they now have, so that could be some amount of extra downforce.LM10 wrote: ↑04 Jul 2023, 16:02It surely will be interesting to see if they keep the classic Venturi floor. I'm far away from being an expert, but I've the feeling it would be their only realistic way to beat RBR anytime soon. I don't think RBR will be beaten with their own weapons - they've been fine tuning this concept for 1.5 years now and will continue doing it so in the next years.
So if Ferrari manages to make their current concept floor work in a balanced way and improve their race pace this way, we might have a proper title fight in hand for next year or the year after. It might sound optimistic, but we know how quickly things can change when a team finally starts unlocking the potential of the car, which has not been the case for Ferrari until recently.
What would you do - abandon the classic Venturi floor or stick to the concept?
The good news is that from here Ferrari took to the track with lower ground clearance without worrying too much about rebound - so much so that he reached the end of the race, especially in the case of Charles Leclerc, with the wear levels of the board bordering on the regulations. No problems or worries at Ferrari, on the contrary, this is confirmation of how the SF-23 was able to travel with more aggressive heights throughout the race, expressing better potential.
There were two separate ride height issues in the early races - one was excessive bouncing at lower speeds than anticipated (as reported in that article, seems to be fixed now) and the other was having too much ride height at the start of the races.dialtone wrote: ↑05 Jul 2023, 10:40I don't think ride height is a problem any more, Charles car was at the limit for floor thickness at the end of the race as reported here: https://formu1a.uno/retroscena-ferrari- ... del-fondo/

What?? Attacking is quite different from the driver in front taking a slow line in an attempt to overtake himself, but being unable and loosing time. Then the car at the back will get closer obviously, but not because he´s attacking, but because Lecrerc lost time trying to pass Max.

When did he attack Lecrerc? Please tell me one single attack Sainz did on Lecrerc
Sainz did nothing, he had a chance to put the nose of his car side by side with Lecrerc, and didn´t. But you say he was attacking and ignoring team agreement. That is bashing a driver with no reason
Only that some driver get critics for things he never did, like invented attacks, while the other don´t, not even when he reckon the mistakes himself
The debate is that there are some people that think Sainz is at the same level as Leclerc?tnajner wrote:Guys, please post something constructive for the debate.

This is probably, like, way overly simplistic, but I wonder if the fuel tank placement on the RB is part of how they manage their ride height better throughout the race?Vanja #66 wrote: ↑05 Jul 2023, 12:28There were two separate ride height issues in the early races - one was excessive bouncing at lower speeds than anticipated (as reported in that article, seems to be fixed now) and the other was having too much ride height at the start of the races.dialtone wrote: ↑05 Jul 2023, 10:40I don't think ride height is a problem any more, Charles car was at the limit for floor thickness at the end of the race as reported here: https://formu1a.uno/retroscena-ferrari- ... del-fondo/

The other issue is a bit more complex, with 95-100kg of fuel the cars can't go as fast through the corners like they do at qualifying. The floor downforce is mostly related to ride height, which in a corner at 150kmh is more related to compression coming from cornering speed (at those speeds, cars generate 8-900kg of downforce) than extra fuel load. So with more fuel you are slower anyway (centrifugal force is the limiting factor) and for Ferrari it also meant they are losing more floor downforce than RB because they are riding slightly higher than optimal. This means suspension requires better correlation with aero, non-linear travel movement, etc...
RB19 is reported to drop very low at fairly low speeds and then stays put no matter how much the speed increases and seems to be just about the only car capable of doing that - making them insanely fast at the start of the race. They also don't have any plank wear issues, so that's also something other teams are curious about.
You talk of the change in ride height in a static manner. The change in static ride height with 100kg of fuel is almost negligble compared to the effects of carrying less speed in the dynamic phase. The cars run way too stiff for the 100kg of fuel to have a major effect on static RH. The positioning of the fuel tank has its effects in its own respect regarding vehicle performance on any fuel load for that matter as it affects the CoG.f1316 wrote: ↑05 Jul 2023, 22:12This is probably, like, way overly simplistic, but I wonder if the fuel tank placement on the RB is part of how they manage their ride height better throughout the race?Vanja #66 wrote: ↑05 Jul 2023, 12:28There were two separate ride height issues in the early races - one was excessive bouncing at lower speeds than anticipated (as reported in that article, seems to be fixed now) and the other was having too much ride height at the start of the races.dialtone wrote: ↑05 Jul 2023, 10:40I don't think ride height is a problem any more, Charles car was at the limit for floor thickness at the end of the race as reported here: https://formu1a.uno/retroscena-ferrari- ... del-fondo/

My logic is: (1) as you say, lower speed in fast corners with full tanks means losing floor downforce, hence ride height (2) more weight (from fuel) at the start of the race ought to, at least to some extent, push the car somewhat lower. Therefore if you can find a way to balance these two things, such that the weight of the fuel creates the downward force at the start of the race and, as they burns off, so cornering speed increases, counteracting the loss of weight with increased downforce.
The forces in question are probably not equal (100 kg of fuel weight vs whatever proportion of the 8-900 kgs of downforce you mention) but it got me thinking about how placement of the fuel could potentially play a part in increasing the fuel weight effect relatively and so help in counterbalancing the competing issues? Perhaps the softness of the suspension also plays a part in helping magnify the effect of fuel weight on ride height?
Fuel tanks have a few general requirements regarding any race car's dynamic performance - the X-coordinate (longitudinal) fuel CoG needs to be very close to car's CoG X value, the Z needs to be as low as possible (but not at the expense of raising other heavier elements), you want to reduce the fuel's moment of inertia by designing a tank that's "close" to a cube and you need to design the internal compartments to prevent excessive sloshing (ideally, you remove sloshing completely). Otherwise, fuel tank shape in F1 is not high in the list of priorities, today they are designed around other systems and are behind the driver of course, some parameters are dictated by rules and they have very weird shapes as a result (compared to what you'd expect from a non-racing fuel tank).f1316 wrote: ↑05 Jul 2023, 22:12This is probably, like, way overly simplistic, but I wonder if the fuel tank placement on the RB is part of how they manage their ride height better throughout the race?
