''Really nothing can be done post turbine'' Again Agree. As both turbine and waste-gates exhaust tail pipes must conform to regulations. ''The turbine is the biggest obstacle'' Again agree. As the turbine is not a 'blow-down' type of turbine (the system used). A blow-down turbine system will have no need for a waste-gate. The turbocharging system as used by F1 + the inclusion of the MGU-H can actually do without a waste-gate, but without a waste-gate the system could not be used in 'free load mode' electrical supercharging mode. with the result of maximum power output possible not being able to be extracted from the ICE.godlameroso wrote: ↑Fri Jun 04, 2021 5:45 pmReally nothing can be done post turbine, the turbine itself is the biggest exhaust obstacle. It's like putting a potato in your tail pipe, or maybe waffle fries.subcritical71 wrote: ↑Fri Jun 04, 2021 5:02 pmI meant at the exhaust outlets. Can the teams influence the aero to allow a sufficient low pressure area in the area of the exhaust tips to promote better exhaust flow.godlameroso wrote: ↑Fri Jun 04, 2021 3:32 pm
The wastegate itself relieves the pressure in the exhaust manifold, so that there is a lower pressure difference pre and post turbine. However the wastegate can't eliminate the heat caused by the combustion process. The turbine actually absorbs some of that heat energy which causes a pressure difference in the exhaust manifold vs post turbine.
Improved reliability which most likely gives more performance :isullivan wrote: ↑Mon Jun 07, 2021 9:21 amEvery other team, apart from RB and AT used a new PU (ICE+TURBO+MGU-H/K) for the Baku GP, yet Honda didn't change anything, granted Yuki is already on his second PU, and yet all of them performed so well on the track. Is this duo to a different PU deployment strategy, maybe they are waiting for France or Austria to introduce a fresh PU ? Can we expect some performance gains duo to "reliability updates" ?
The following could be read on AMuS last Friday after the 2nd FP, which was not true at all.epo wrote: ↑Mon Jun 07, 2021 12:10 pmImproved reliability which most likely gives more performance :isullivan wrote: ↑Mon Jun 07, 2021 9:21 amEvery other team, apart from RB and AT used a new PU (ICE+TURBO+MGU-H/K) for the Baku GP, yet Honda didn't change anything, granted Yuki is already on his second PU, and yet all of them performed so well on the track.

The Honda teams still had the old engines in the car on the first day of training, while Mercedes and Ferrari had already switched to the second engines.
It was heard from the team! that Honda will also switch to new drive units on Saturday.
It can still be a reliable source but RB/Honda decided against using the 2nd engine. Maybe because they felt they didn't need it yet, because they were so strong on Friday. With rose-tinted glasses you could say this points into the direction that the rumor stated on this forum may be true that the 2nd engine has overcome some reliability issues and can therefore be run a bit harder.Wouter wrote: ↑Mon Jun 07, 2021 7:12 pmThe following could be read on AMuS last Friday after the 2nd FP, which was not true at all.epo wrote: ↑Mon Jun 07, 2021 12:10 pmImproved reliability which most likely gives more performance :isullivan wrote: ↑Mon Jun 07, 2021 9:21 amEvery other team, apart from RB and AT used a new PU (ICE+TURBO+MGU-H/K) for the Baku GP, yet Honda didn't change anything, granted Yuki is already on his second PU, and yet all of them performed so well on the track.

The question is therefore whether this information about France this time is correct.

No in-season development allowed, only reliability fixes
They are only allowed 1 update per the technical regulations.
Huh, I thought we had a complete freeze starting in 2022 (allowing the RB - Honda deal)? This FIA document says something different.dans79 wrote: ↑Tue Jun 08, 2021 9:16 pmThey are only allowed 1 update per the technical regulations.

As far as I know, that was blocked in the regulation change last year.
Yea, and it's not even clear what the 1 that spans 2 seasons means!Pyrone89 wrote: ↑Tue Jun 08, 2021 10:11 pmHuh, I thought we had a complete freeze starting in 2022 (allowing the RB - Honda deal)?
