Nugnes is pure clickbait, wouldn't trust a word.
Let's be real, where would 50 HP come from? Did Honda's engineers suddenly figure out all of their issues and make them right in 6 months after having not realised for years before? I would temper my expectations, engines have long lead times and there's only so much you can do in 6 months. Improvement? Yes. Revolution? No.
The answer would be in the question "how did Honda go from contemporary established that was was very competitive in last rules set, to loosing so much ground in combustion theory/practice for this next set of rules, in place now ? "
Clearly they knew (evidence based) what to do before, but failed in carrying that to the development of a similar design (with lower specific output, but more fuel quantity limited) for this era.
There is valid store in Ispano6 view about Aramco contribution that I believe in part for these reason. Fuels for another formula (often stated in here as valid) have no real bearing on the specifics of detailed fuel for these fuel starved and almost diesel like combustion design that are part of this (and previous rules ) PU architecture.
The "fingerprint" of fuels used, held by the fuel companies for last era rules set, have a huge influence in formulation. That's missing from Aramco product it appears currently, from "polite" information coming from Honda engineers.
Like noted above, that will take time and extensive experience to resolve. One key to that is the minds previously used by Honda to tutor the current development team. That can give a big jump IF they fully recognised the existing short coming that has limited their combustion advance so far in PU running in first half of 2026.
The proof though, we'll have to wait until NL to find out. Speculation in this is highly unreliable, unless specific information from verified sources are available.
