Perhaps both matter?
Read the whole sentence please lol... I merely said it's worth noting.
I don’t think it has anything to do with PU performance, it’s just a packaging improvement.ispano6 wrote: ↑01 Oct 2020, 04:38I guess what I'm wondering is why Renault are now opting to go split turbo if their current PU is more powerful than Hondas. Had Honda been able to bring spec 2 and 3 this year instead of 1.5 then it might be a lot closer to Mercedes while Renaults current architecture has reached its ceiling and maybe Renault has recognized that?
How will peak horse power matter if it cannot even be sustained over a few seconds at full open throttle to the end of a straight stretch of a track?. .

To be honest I don't know if radiators used this year can or not be changed for free or not.Blackout wrote: ↑01 Oct 2020, 11:19Blackout wrote: ↑28 Sep 2020, 10:53The (updated?) regs say "All water-oil or water-water coolers" (are frozen) but what do they mean with "water-water"? and this means that intercoolers arent frozen indeed.

Great. More numbers to the library..Blackout wrote: ↑01 Oct 2020, 11:12Only Renault can answer point 1 and 2.
Regarding question 3, IMO, on the paper they can, just like Mclaren which will go from a 'classic' Renault engine layout to the Merc split-turbo layout... but I dont understand how Mclaren will be able to do that with only 2 tokens...
-They'll spend their 2 tokens changing the rear half of the monocoque, but as far as I understand, they'll need to change the fuel tank too* (1 or two tokens), and what about the cooling (2 tokens)?
-Or is it somehow permitted to change those things for free?
The gearbox is not a big problem. They can keep the 2020 one. If your Gbox can host the whole renault turbine, then it can contain a lonely turbine.
*Because the Merc layout penetrates the rear bulkhead and the fuel tank much deeper than the Renault one.

Reading between the lines the nextgen Renault PU has completely different cooling needs..."The balance, about 150 kW, is dissipated in the car's coolants: engine water, gearbox and hydraulic oil, etc.".

Do you understand the meaning of "BOTH"?saviour stivala wrote: ↑01 Oct 2020, 05:02How will peak horse power matter if it cannot even be sustained over a few seconds at full open throttle to the end of a straight stretch of a track?. .
22.8.6 In the event a Competitor wishes to carry out a completely new Power Unit installation (whether because of a new Power Unit Architecture, or because of the change of Power Unit supplier), affecting both the survival cell and the gearbox, no further tokens may be used for other components under the provisions of Article 22.8.4.
In such cases, the Competitor must satisfy the FIA that the proposed changes to the design of the affected HCs are the minimum necessary to allow for the new installation of the Power Unit. No further changes to the affected HCs may be carried out, nor may the adopted technology be different from the original HCs.
In order to fulfil this requirement, the Competitor must organise with the FIA a schedule of regular CAD design reviews, in such way that should the FIA have a concern about the proposed extent of the modifications, a remedial action can be decided in a timely manner.
