Introduction[]
I will be calculating Momoshiki’s feat in the Boruto Movie Novelisation where Momoshiki absorbs chakra from beyond his dimension. Which is a cannon feat.

Calculation 4-C[]
Momoshiki absorbs chakra from beyond his dimension. His dimension should be at least as big as Kaguya’s since it has light even though thick clouds cover the sky. Also he should out-scale her via statements from Kaguya herself, Momoshiki and Saskue.
Why there is a star in his dimension? Theres sunlight verbatim.
The Boruto Movie Novelisation also states
And
Were not given an exact time frame, but we can say for sure it took less than a mins for the chakra to go from the sun to the Earth if not a few seconds via the anime since it happened while he was transforming.

This would mean Momo was pulling the chakra at:
LOW-END If it was 1 min 8.316897850142633xFTL 8.3xFTL
HIGH-END If it was 10s 49.9013871008558xFTL 49.9xFTL
However his dimension should be 4-A the anime shows it as so (the stars are circled in red) ⭕️
Calculation 4-A[]
We know Naruto’s world has a starry sky it’s shown several times.
Momoshiki creates a dimension which is stated by Saskue and Naruto to be parallel to the real dimension.
In the movie novelisation it is stated he is absorbing chakra from "beyond" that "parallel dimension he created"
According to Kep the farthest bright star visible from the unaided eye is Eta Carinae A, a red hypergiant that lies roughly 7,500 light years away from our little dot full of life. https://www.constellation-guide.com/eta-carinae/

In 24 hrs since the fight is no longer than this, massive low-end
8.21238E+14 m/s

2,739,355 xftl
Conclusion[]
More likely Massively FTL+ since it’s been established his dimension is parallel to Naruto’s dimension and he began draining chakra beyond it very quickly. Of course this is a Boruto Movie Novelisation feat which is canon since it’s not retconned and is still on the official Timeline with the Resuden Novels however it’s not shown in the Manga or Anime.
