As far as I know there is only a packaging advantage the split turbo has over the other one.codetower wrote: ↑09 Jun 2021, 17:41Is there an advantage to going split turbo vs combined or is it just "another way of doing things"? I sure hope Ferrari aren't falling further behind the pack by sticking to the combined turbine/compressor approach. It will be interesting to see if it pays off to go against the norm. I sure hope it works...wowgr8 wrote: ↑09 Jun 2021, 16:21https://the-race.com/formula-1/key-deta ... -revealed/
KEY DETAILS OF FERRARI’S AMBITIOUS 2022 F1 ENGINE REVEALED
Although Ferrari has looked very closely at the split turbo concept – whereby the compressor is mounted at the front of the engine and the turbine further back, linked by a shaft running through the vee of the engine – it has decided not to follow that philosophy for the new engine.
The innovations are understood to include the intercooler solution and significant gains are believed to have been found in the energy recovery’s electrical system but the real innovation may be in the combustion technology.

Although the architecture will remain ‘conventional’ in terms of the turbo’s layout, the intercooler and other changes are understood to allow for a significantly more compact package than the current unit.
[...]
With Alpine having unofficially confirmed that Renault will switch to a split turbo for its 2022 engine, that leaves only Ferrari in the combined turbine/compressor camp.
According to the article Ferrari is going for a radical change, seeking for both significant power and packaging improvements - without going the split turbo route.
Just because all others do it does not mean that it’s the only or the best possible way. Want an example for that? Mercedes has been the only low rake car in many years.
