The bell test went pretty much the same as in the original. The only difference is that even though Naruto had gotten significantly faster over the years, Kakashi could keep up with that speed with his sharingan. As of right now, Naruto's top speed is around Mach 3, i.e, thrice the speed of sound. Although the difference was that while Naruto and Sakura co-ordinated pretty well with each other, Sasuke was the one tied up to the log simply because he wasn't co-ordinating. In the end they did pass the test though.
They were significant changes in the land of waves though. They were able to finish off Zabuza in thier very first encounter with him, which means Haku joined in the fight a lot sooner although by the time he did join, Zabuza had died, so it was a 3v1 with Kakashi, Naruto and Sasuke up against him. I also forgot to note that since Sasuke's life is a lot more darker he had already awakened his sharingan and he had two tomoe in both eyes when he fought Haku. Although he did hate the village. He started to see his team in a different way, he realised that they don't hate him as much as other people do, but there was no significant change in his behaviour.
Sasuke was about as strong as he was in his fight against gaara during the time when he was in the land of waves.
Naruto's top speed increased to around Mach 4 by the end of thier fight. Sakura started to develop an inferiority complex because she was unable to do anything significant. Naruto had also been practicing techniques like throwing lightning, the supercharged punch, speed Mirage and phasing through. Although he still hadn't mastered speed Mirage and the phasing techniques clearly. He still didn't know anything about time travel and opening breaches yet.
[Yeah I know this chapter's been written at a ridiculously fast pace, Why?.. Cuz I want to get to the interesting parts as soon as possible. I'll slow down the pace a bit from here on out and as I mentioned, I am open to suggestions and criticism.]
