There is no confirmation on this turbo size rumour.
A smart engineer who has learned from the previous regulations will always go the maximum turbo size considering the engines are hybrid, and always thinks about race pace not just the start of the race.
I have been vocal on this. It would be silly to run a smaller turbo when you need as much power as possible in the higher rev range of the engine.
I feel Fred is playing reverse psychology here. The Ferrari starts are good because they have a solution for it and wanted to keep an advantage not because they have a small turbo. Why would you purposely make an engine weak for 98% percent of race? When you have overtaking aids?
I am with you. There is no suggestion from anyone at Ferrari that a smaller turbo was chosen. The only thing Fred said was that they designed the power unit as a whole to start well.
For all we know, they worked on how to spool the turbo quickly. Or, a completely different method of getting off the line quickly. Ferrari have plenty of experience with starting systems.
Well every reputable journalist - who have inside sources in the teams - is reporting that Ferrari has a smaller turbo. Bear in mind: 1) Ferrari is widely believed to have used a smaller turbo in the last rules cycles so likely see other benefits as well 2) Fred called this a tradeoff worth 1 tenth per lap - so we’re likely talking smallER but very small differences.
In any case, this isn’t really the point - everyone is reporting Ferrari have a smaller turbo, you don’t believe it…fine. But what PlatinumZealot said was that Ferrari could have changed something and *chose* not to - I’m trying to understand what it is you think they could have changed and, if so, why they would have actively made a choice not to do something that was beneficial given new start procedure?
Ferrari had a small turbo in 2014.. Then they changed to a very big one in 2015... This was well documented here on this Forum. This played out well till the end of 2019 when Ferrari were formidable on the straights before the fuel flow trick was banned. But you don't allow more fuel without a huge turbo. After that they still kept a bigass turbo.
Forget the journalists. It just doesn't make engineering sense to use a small turbo if you have this amount of hybrid electric power. The turbo is an easy scapegoat for a weak combustion design. There is no way even the regular car mechanics will evem see the diameter of the turbine wheel, usually just the engine department will actually have seen it.
Perhaps ferrari combustion design is good at low end torque but weak at higher rpms... We just dont know.
