You assume the engineer overseeing the running of the power unit knows anything about cooling design. Or is privy to the parts before assembly.Matt2725 wrote: ↑03 Jun 2025, 14:05McLaren have a bespoke cooling package for their PU which is designed in house. It allows them to better cool the PU and you'll note, they often have smaller openings in the bodywork as a result.Hammerfist wrote: ↑02 Jun 2025, 19:38How is it possible that the factory Merc car is having all these failures and meanwhile customer Mclaren is completely trouble free?
Thing is, HPP will be fully aware of what McLaren are doing regarding cooling as their own employees are embedded within the customer teams, looking after the PU.
In theory, they could apply that knowledge to the works team but good luck getting it past the FIA I'd imagine.
Regarding Spain,
Russell's pace in the latter stages looked quite good all things equal. Both he and Max were actually catching Charles back up quite rapidly prior to their ding dong. Indeed even after that, Russell crossed the finish line very close to Leclerc.
McLaren won't be giving away such an advantage on cooling. Some of them, were there when HPP shafted them for 2014 with deliberately not updating the cooling data and leading to McLaren designing a boat in comparison.
