It's all good fun... I like that they can do stuff like this, at the risk of looking silly...TAG wrote: ↑21 Oct 2018, 18:23https://scontent.fagc1-2.fna.fbcdn.net/ ... e=5C41B00E
I have to say, I'm a little embarrassed for them.

In Bedford. Why?
Well, maybe it is just semantics, but last year in Mexico Renault was reminded their turbo has almost no altitude margin.
I think it was Cyril who said after the race that the cause of so many retirements was that they didn't turn the engine down. This was later corroborated when Horner said he was surprised Renault slowed turbo revs for Brazil without telling them. Turbo has been such an Achilles' heel for Renault. Even this year. I'm not sure they can still turn up the revs this year to avoid choking.noname wrote: ↑26 Oct 2018, 08:31Well, maybe it is just semantics, but last year in Mexico Renault was reminded their turbo has almost no altitude margin.
Initially they run it faster, as you usually do when ambient pressure drops down, but they had to revert to "see level max speed".
And yet the one in Ricciardo's car failed during the race, connection between turbo and MGUH gave up.
So maybe they did not turn it down, but they could not turn it up as much as they would like to compensate for altitude.
Reliability-wise 2017 Mexico GP was disaster for Renault, with only 2 cars (out of 6) with their engines at the back reaching finish line. To make things worse they had to replace PUs in Ricciardo and Hartley cars before the race. And Red Bull turned Max car down during the race.M840TR wrote: ↑26 Oct 2018, 09:34I think it was Cyril who said after the race that the cause of so many retirements was that they didn't turn the engine down.

Well, turbos usually take the brunt of the altitude impact because they're responsible for feeding the air to the engine and have to work extra hard when the air is so thin. Going by that and the general lack of reliability of the turbos in the Renault PU, it would make sense they run more conservative than usual, which they didn't last year.

I think aero was ok, and chocking should not be an issue. More probably reason was turbo and MGUH rotor(s) and bearing system(s) design having certain features, or maybe design-flaws would be a better description, being carried over from their V6 PU inception.
