Not the ice though, just the mgu-k
The bit about Bottas’ special engine map can only be a ‘rumour’, surely? Weren’t the rules framed around a single ICE map per engine manufacturer per weekend when they got rid of multiple engine maps last year?atanatizante wrote: ↑22 Oct 2021, 20:23Yeah, I think so too ...
In the team thread, I wrote about "there are rumours saying that the 3rd spec PU was built with an eye toward the E10 biofuel that should be used in 2022.

The same rumours are also saying that 2021 Merc PU having to cope with more races/km than last year was wear out at a faster rate towards their end of the duty cycle than it was designed for and the reason for that is the fierce battle between them and RB/Honda, which forced them to use more and more aggressive PU mappings in races, all coming with some negative consequences: they have found some issues at the crankshaft and valve seats ..."
I wonder if the the map and ICE are considered a single item with respect to that rule - a new engine requiring a different map which won't work on the previous version engine and the old map not working on the new engine either, for example (an extreme example but only to make the point). At that point, the other teams would get the map/engine when their scheduled swap came due. That would be within the rules, unless they state specifically otherwise.Stu wrote: ↑26 Oct 2021, 07:14The bit about Bottas’ special engine map can only be a ‘rumour’, surely?

It seems Mercedes will push the limits of their engines at the expense of durability.
"The data that emerged after the American race are encouraging and the intention would be to take risks in the next GPs, raising the boost very close to the reliability limit in order to extract about ten more horsepower in that threshold which is no longer the comfort zone of Hywel Thomas' motorists."
If Lewis Hamilton gets the opportunity to keep up with the Dutchman's Red Bull RB16B, there is a desire not to back down in the "engine war".
"The considerations that have been made are quite simple: even if a power unit were to break, Lewis would still remain second, so it is worth taking some risks to try to fight at the top."

But wouldn't a DNF ruin any chance of winning the WCC?pursue_one's wrote: ↑31 Oct 2021, 21:38It seems Mercedes will push the limits of their engines at the expense of durability.

well no .... altitude makes no difference ....atanatizante wrote: ↑03 Nov 2021, 13:19... bear in mind the low O2 per cent in the air due to high altitude?
From what I`m aware off Tommy this is not entirely true (happy to be proved wrong)! Well not according to this.Tommy Cookers wrote: ↑03 Nov 2021, 14:19well no .... altitude makes no difference ....atanatizante wrote: ↑03 Nov 2021, 13:19... bear in mind the low O2 per cent in the air due to high altitude?
the percentage of 02 in the Mexico City air is the same as the percentage of 02 in the air at sea level etc
btw high % water vapour correspondingly displaces all the other constituents of air eg by maybe 8% at Singapore
but % water vapour always low at altitude
In Mexico City, a cubic meter of air contains 212 grams of oxygen, while at sea level it contains 275. The combustion efficiency of a well-tuned car is 92 per cent, and in the DF 69 per cent, due to the higher altitude.
take a look at this it simplifies a lot of otherwise complex information for easy consumption. this is in relation to altitudes a human would survive at.Mattchu wrote: ↑03 Nov 2021, 17:19From what I`m aware off Tommy this is not entirely true (happy to be proved wrong)!

yes a cubic metre of MC air contains 212 gm of oxygen (77% of the sea level amount) ....
I think you confused volume percentage within a gases composition with mass percentage due to altitude/pressure ...Tommy Cookers wrote: ↑03 Nov 2021, 18:51

Not a reliable source, you might say they are particularly unreliable evenatanatizante wrote: ↑03 Nov 2021, 13:19Some rumours about PU gaining some 630g weight due to changing some sealants (due to running higher than usual engine/PU maps with this 3rd PU and probably allowed by the FIA) that led to a 10HP increase in power output or maybe due to finally getting the only update this year for fuel & lube and other stuff here on Missed Apex Podcast:
In addition, what effect should have at Mexico race the new air intake plenum, bear in mind the low O2 per cent in the air due to high altitude?
Could all those above have determined BOT to say that now their PU is more powerful and "optimised" for the Mexico race?

Tommy is not confused. Percentage is not the correct term for specifying the number of molecules or grams of oxygen in a given volume of air. Percentage is a dimensionless term ie g/100g or L/100L.atanatizante wrote: ↑03 Nov 2021, 21:59I think you confused volume percentage within a gases composition with mass percentage due to altitude/pressure ...Tommy Cookers wrote: ↑03 Nov 2021, 18:51yes a cubic metre of MC air contains 212 gm of oxygen (77% of the sea level amount)
Indeed, both at sea level and altitude we have the same 20.947 volume % of O2 in 1 cubic meter of air, as you correct above stated. But this volume weights differently at different altitudes/pressures due to the ideal gas law: pV=nRT. Thus, at the same volume when pressure lowers due to altitude we have fewer molecules so less mass or weight of O2 as Mattchu said in another post above ...
Anyway, no one has an idea how the ICE would cope with the new air intake plenum here in Mexico, bearing in mind it was designed to provide cooler air hence feeding more O2 for the engine?
