Agreed in that compression ratio has extremely little to do with a deficit of this size. It demonstrates an extremely premature combustion system.diffuser wrote: ↑03 Jun 2026, 21:04Everyone says that the beyond 16:1 CR is worth like 10-15 HP (while Merc says 5 -10) whatever it is ... from the video, Only Ferrari seem to be 2 KPH down and then Honda woefully down. Audi seem to be as strong as RBR and Merc, ironically. Honda missed more than just the grey area to be that far down. Or maybe you were being sarcastic ?Badger wrote: ↑03 Jun 2026, 20:28Yeah that's why they're missing 70 HP, because they missed a "grey area" that everyone else foundHonda is the only outlier in terms of the engine, how s**t it is relative to the other four. RBPT and Audi have shown that these regulations are far from impossible by mastering them as newcomers.
Honda literally said they utilised, to great extent, in-cylinder pressure sensors to fine tune the combustion design they developed last regs. And Honda themselves said it was a "necessity" if they were to run the engine in the manner they were. The loss of ability to use them this year, to accurately monitor and tune individual cylinder events, has harmed them massively. This feels like 2017 all over again when they first brought in a TJI style ignition/injection setup... they openly admitted they had no idea how to operate it or get the best out of it but brought it in knowing it's potential and figured it out down the track. Either way, this deficit and their words just HEAVILY suggest they are back at square one again, and their "rapid combustion" tech from late 2018, and later perfected, is essentially gone and probably exacerbated by this new fuel that's in its early stages.
