I suppose from what i read here and its a general feeling, that Ferrari went to smaller turbo to mitigate the loss of MGU-H in Race Starts. Offcourse the constantly changing of the the rules for the race starts, made them to feel stupid they will need to change that.f1Follower wrote: ↑22 Apr 2026, 21:45So if the new rules promote to have bigger turbo will Ferrari move to have bigger turbo. Mercedes and others were successful in changing startup turbo lag with power from MGU-K
They don't promote that. The changes to start procedures mitigated it a little but the recent change won't affect it. They are for starts where drivers are basically stationary or have anti-stall kick in.f1Follower wrote: ↑22 Apr 2026, 21:45So if the new rules promote to have bigger turbo will Ferrari move to have bigger turbo.

They have fixed engine free upgrade cycles. I think it's every two years or something like that to 2030.

i din't know there min and max size for turbo, does like what 1 cm make that much difference??PlatinumZealot wrote: ↑23 Apr 2026, 15:05No one knows but Ferrari what the diameter of their turbine wheel is. The rules allow 90mm to 100mm. It might be silly not to use the full 100mm allowed because there are other ways to get quick spooling and that's free horsepower left on the table.
Yes! It makes a huuuge difference! For roto-dynamic machinery a few square centimeters or millimeters can even change flows and pressures by double! It is too much risk to go smaller, risking top end flow and hoping your rivals have a slow spooling turbo. I don't think any logical engineer would take the risk on that side of things. I would rather go maximum diameter and then figure out how to spool it quicker (let's face it, once the cars are up and running, the turbo can be kept spooled up, even in slow corners). Mercedes still beating us on traction out of corners.Fakepivot wrote: ↑23 Apr 2026, 16:46i din't know there min and max size for turbo, does like what 1 cm make that much difference??PlatinumZealot wrote: ↑23 Apr 2026, 15:05No one knows but Ferrari what the diameter of their turbine wheel is.

As a bonus looks like we'll get 90 minutes in FP1 to assess the wing and the other 1.1 of the update package.
Vasseur said many times that they choose a smaller turbo. Or am I mistaken?PlatinumZealot wrote: ↑23 Apr 2026, 17:53Yes! It makes a huuuge difference!

I don’t think it’s been explicitly said that it’s a smaller turbo - I also don’t think it was confirmed 100% that they had one in the previous rules cycle.sucof wrote: ↑23 Apr 2026, 21:26Vasseur said many times that they choose a smaller turbo.

"That’s why we made certain decisions, and the FIA has been quite clear from the beginning about not wanting to change the starting procedure, so I was surprised when this topic resurfaced in Bahrain."
Vasseur added that "compromises" had been made in Ferrari's design process to accommodate the previous situation, although the Ferrari-powered cars generally appeared to enjoy stronger getaways at the start of the race despite the application of the five-second hold period.
I thought I was the only one who was questioning where the idea comes from that Ferrari has a smaller turbo.PlatinumZealot wrote: ↑23 Apr 2026, 17:53Yes! It makes a huuuge difference!
