Ferrari Power Unit Hardware & Software

[FW17]

Maynot be the air box but the duct leading to the intercooler at the back. Fire somewhere in the rear.

[Mr.G]

It was the paper air filter...

The turbo failed, so hot oil may have come through compressor seals and burnt and back fired into the intake.

Motorsport-magazin states that Ferrari has made a step back in power output compared to 2015. The reason therefore is the compromise they had to make on the packaging side in order to gain chassis benefit.
Motorsport-magazin bases their assumptions on sector speed traps and top speeds from the 2016 Australien GP compared to 2015. I don't really believe so, given the fact that such motorsport-news sites often present wrong facts (oftentimes they misinterpret Eau Rouge corner speeds as top speeds at Spa-Francorchamps and such stuff) and make superficial analysis.

Anybody got more reliable sources on that topic?

Fry told that Ferrari used detuned engines.

I think the Ferrari power unit was running at reduced power during the Australian Grand Prix weekend. Even the Mercedes bosses thought so.

Could somebody provide the ”clean” pictures without markers?
I mean ferrari factory pu pic from this season.

Top speed depends on how much down force team wants to have during the race. Don`t forget, In 2015 Ferrari finished over half minute behind Mercedes, Ferrari with better top speed last year. It is all about hole package, much down force and just enough top speed. Teams prefer better down force then higher top speed.

Those differences are minuscule at a track like melbourne park. Especially since 2014 onwards with the reduced wing angles and dimensions. Pretty much all teams run max downforce they can, bar a few really inefficient parts.

Bahrain will be a much better test.

If I remember correctly in 2015 at Monza the registred top speed were lower than 2014 ones, but the cars were quicker.

Supposed Ferrari engine problems:

http://www.auto-motor-und-sport.de/form ... 00337.html

Summary:
- Ferrari are slowed down by a turbocharger issue, which they hope to fix until Spain
- GPS data shows that Ferrari stop accelerating in the second half of the straight
- both Vettel and Räikkönen get new control electronics in only the second race of the season
- the new engine is hugely improved, but the turbocharger causes issues
- new turbo can run with a higher boost, but then the MGU-H cannot recover enough energy to charge the batteries
- engine goes into charging mode in the second half of the straight, which costs power
-spinning the turbine too high can cause failures; Räikkönen's turbocharger overheated in Melbourne, which caused the fire in the airbox
- problem emerged during testing and Ferrari, unsuccessfully, tried to fix it with new software
- Ferrari car is quick in the corners and good on its tyres, but they lose time on the straights in Bahrain
- in conjunction with Honeywell a new turbocharger has been developed, but lead time in turbocharger development are up to 12 weeks
- Ferrari hope to have the fix ready until the first European races
- restricted power costs 0,5sec/lap so if the fix works they would make a big step towards Mercedes
- turbocharger experts warn that in this area weaknesses might not be cured in the first attempt

Personally I think here was some obvious power cutting in australia but this is blown out of proportions and is waaaay too generalized. What kind of straight? What engine modes?
Today grosjean reached 314 kmh on the back straight on his super soft run which was faster than rosberg (310) and hamilton (314) on their SS runs.

I am still not sure where the problem is when Haas can run it without a problem. Maybe they are trying different PU settings? I cannot believe they wouldn't test all race tracks inhouse...

basically what Amus is speculating about is that because the Ferraris are running a larger turbocharger they are now having to deal with turbo lag. To combat this turbo lag they are using energy from the Battery to spool up the Turbo which leaves them with less battery power to deploy at the end of straights.
he claims that an easy fix is raising the RPM of the Turbocharger which Ferrari did and was why Kimi's turbocharger failed in Australia.
He also claims that Ferrari changed the control electronics on both cars to combat this issue but it didnt resolve the issue.
He says that Ferrari plans on changing turbochargers in time for spain which will fix the issue when they planned on changing engines anyway.
they may be able to make the change with no use of tokens since it is a reliability issue.
its ALL speculation at this point based on the fact that Ferrari are not going as fast as he claims they should be going at the end of straights and kimi had a turbocharger issue in australia.
who knows if its true or not....
