Ferrari F14T

[Holm86]

Ferrari ready to be more 'daring' with engine maps. Happy with the reliability of the new engines Ferrari is ready to take the engines to the next step with more agressive mappings. This will happen at the Canadian GP.

Allison on the Ferrari vs RB vs Merc. For all the Pull-rod front suspension nay sayers..he does say the front is stronger than the back.

Mercedes currently has a significant engine performance advantage over Ferrari, but Allison says his team's chassis is also not a match for Mercedes or Red Bull.

"We have been relatively strong at front-limited tracks over rear-limited tracks, but I don't think that we could claim to have produced a chassis that is, at the moment, the equal to either Mercedes or Red Bull. We're not lagging hugely behind but there is still work to do before we can say we are truly happy with the chassis performance.

"It's very difficult to have a rate of improvement that is substantially different to the people we are racing with. However, we've had a race or two where the pieces we have brought to the track were useful but not big steps forwards. We hope in the coming races to have a more steady progression of things that we hope will lift us somewhat, but we won't know for sure until we see what everyone else does as well."

Monaco tech: Ferrari engine revealed
There weren't too many aero tweaks for Monaco this year, but practice provided an answer to one of 2014's big remaining engine tech questions, as CRAIG SCARBOROUGH explains

Monaco has long been about maximising downforce without worrying too much about drag, but with Formula 1 teams having to exploit ever-more restrictive aerodynamic regulations, they are already running near or at the maximum in most races.

So the traditional Monaco-specific set-ups are now becoming more of a simple variation on the baseline.

As a result, the developments seen this weekend are subtle, but there are still some interesting changes - and practice also revealed one of the pitlane's remaining 2014 tech unknowns.



For a team steeped in F1 tradition and proud of its engines, Ferrari has remained secretive about its 2014 power unit. No images of the engine have been revealed and technical personnel have been kept away from the track and the media.

The exact format of the engines was exposed when the unit was being removed from Kimi Raikkonen's car in free practice.

Ferrari has the turbo at the back of the engine like Renault, but like Mercedes it has split the exhaust driven turbine from the compressor.

The separation is far smaller than the Mercedes arrangement, with just enough space to mount the MGU-H in between the two components.

With this set-up, Ferrari can mount the turbo much lower, as they do not need to fit these parts within the 'V' of the engine. This means the turbo can be much lower within the gearbox for better aerodynamics and a lower centre of gravity.

Now the turbo needs to cool the charge air and route it to the front of the inlet plenums. This was unclear until Thursday, but Ferrari fits the water intercooler in between the inlet plenums, within the 'V' of the engine.

Then the intercooler has a U-bend to duct the cooler charge air to the inlets. Separate water pipes then take the heated to water to a smaller radiator in the sidepods.

This keeps the hardware out of the sidepods and fuel tank area for better aero, and the pipework short for less turbo lag. In this guise, the Ferrari engine architecture is at least as elegant as the Mercedes. But it does come at the cost of some extra weight for the water intercooler.

It's unfortunate for Ferrari's two customers, Marussia and Sauber, that they also get this set-up as part of the complete Ferrari powertrain supply.

They are less able to reduce weight from the rest of the car to accommodate the heavier engine installation.

So, cliff notes would be..... cool design, but too heavy.

And making matters worse, the weight is added above the cars center of mass.

But the lower turbo lowers the center of mass, and frees up sidepods area. Go figure, it prob was awesome on paper, but failed in practice. Will have to see whether the new "aggressive" engine mapping will do anything.

I suspect that it comes out worse. The turbo is being lowered but is closer to the center of mass. The influence of mass is proportionate to the square of the distance, and the added mass of the water intercooler is quite high up. On paper it probably looked a little slower in the corners but higher enough power/more aero to compensate. Unfortunately against the Mercedes, it's neither yet, though they might do well against RB on the high speed tracks.

[tok-tokkie]

The influence of mass is proportional to the square of the distance if the mass is rotating - as in wheel or crankshaft. In this static installation it is directly proportional to distance above ground.

[johnsonwax]

Except the car wants to roll in various situations and that roll must be combatted. The higher mass will induce roll and that will carry a cost on suspension and tires. Maybe not a lot because it is close to static as you note, but it adds up...

"We have been relatively strong at front-limited tracks over rear-limited tracks, but I don't think that we could claim to have produced a chassis that is, at the moment, the equal to either Mercedes or Red Bull.

One could actually see that by watching the Ferraris sliding at the exit of corners where Merc and RB look like on rails compared to that.
The design of their nose could potentially be somewhat related to that property.
A car with a low nose tends to have copious front DF but restricts airflow to the rear end, causing DF loss at the back of the car. If you compare the narrowest free cross section of the Ferrari nose with Merc and the RB, it has a much smaller minimum free cross section as the other two. Merc had a very clever interpretation of the rules and RB moved the required central section forward of the wing mounts so that the minimum cross section between the mounts is almost unimpeded by the central part.
I'm wondering if they are working on a Merc or RB nose to compare it with their exitsing one.
Might be at least worth a try in order to mitigate the problems at the rear.
All this might be moot however, if their real problem is flow separation at the coke bottle. Then moving more air to the rear won't be of much help.

Coke bottle separation? Where did word of this come from? I agree with Allison that the F14T tends to do better at front limited circuits, a trait of it's predecessors. I haven't heard any mention of flow problems at the rear of the Ferrari's but it's interesting you mention it because in China, the teams best result, they used the blown front wheel hub. We know it pushes the FW wake out which comes back in right around the start of the coke bottle. Coincidence?

Ferrari has changed the front suspension for Monaco so the front tyres don't rub.





Piola says Ferrari have modified the central cooling vent to a larger version, although I can't tell.

we had said a few days before;-)

Just a wild assumption on my part.
They have a very agressive angle/radius behind the widest Point of the sidepods plus a relatively low overhanging cooling exit. This overhanging part will increase steepness of the anyway steep adverse pressure gradient in the coke bottle area.
Seeing the red cars often dancing around with their rear end lead me to believe there might be an issue with stability of rear DF. Random separation of coke bottle flow could potentially cause such.
