I guess you are talking about the BLX version?

On 2S this is not possible out of the box. More around 35mph.
You could go for a bigger motor pinion, see your Arrma manual for the exact details. But that is on flat, high grip surface only: Tarmac.

You need more kv motor, and possibly a more powerful ESC.

But why?
The BLX version is already fast and difficult to reach top speed already?
