Yes, you can have things run above 100% speed.
Basically Fusion already let you set the Movement Timer in the each Frame properties, they are 60 (to match 60fps speed) by default.
The extension allows you to not only set that during gameplay but also get the deltatime so you can integrate more stuff to it.
Here's a video of an engine I've made using the extension, and you can see I testing the time speed.
