the 9:39 is a much better time trial. I even saw a lot of time save in that video, so i bet sub 9 is doable.
I have a small time save for solar that i wanna make sure you know about. After placing the charges (before you take the elevator to the last part of the level), there is a set of body armor. You're intended to walk up a small set of stairs, pick up the armor, then vault over the rails and get to the elevator.
But the time save is that you can actually pick up the body armor from the side, without having to go up the stairs. So just run straight for the elevator door and touch the corner of the armor and you should pick it up.
edit: I forgot to mention that most body armor in the game is like this. Sometimes there is also armor inside a crate that you can pick up without shooting the lock. This doesn't work everywhere but each one saves a little bit of time.
