Let's chill out for a second.
Weekly, I am siding with Kep, Burning, Rocker, and the others.
The speed advantage isn't massive in her base, not even enough to blitz at all-- and unless you can pull out a multiplier or something, we can't really take it into account. The reason being is that it's vague, and because of that, we don't know if Naruto will be able to handle it-- and, if it would really change the fight significantly enough to matter-- for all we know, it could be another 2x increase, which is closer to blitzing, but not too far to the point where it's a speed blitz. Usain Bolt can't speed blitz most people, considering he's peak human. 4 times faster might push me, but it's not enough to speed blitz-- barely tho.
Doesn't deny the rest of what we said. Her intangibility, can she attack while tangible? And has she ever gotten hit before aside from that one PIS moment? Because if Speed and intangibility that is only useful on evasion are the only things she has, I don't see her winning. In addition to the fact that she won't outlast Naruto in stamina. This guy can divide himself into Clones that can create 1,000 copies and up, and do it again-- fight for days straight in a war, etc. Sure, those were feats for him later in the series, but it's a testament to his stamina-- in addition to his Uzumaki clan lineage granting him that Stamina, and him in the beginning of the Series summoning up a BUNCH of clones without breaking a sweat.
If she can't hit him without being intangible, she dies. Plain and simple.
