How do I change the Ball speed in a roller game?

[sakers288_1 (Steven Akers)]

Just wondering if anyone could tell me what I need to change in this blueprint to be able to change the ball speed in my roller ball game. If i could be able to use shift to at least speed the ball up or even just speed the ball up overall. I’ve tried messing with the torque value and raising it but it has no effect on the ball speed. This is my current setup I got from a tutorial by Damian Nowakowski.

Also, along with increase of torque necessary to alter the maximum angular velocity in properties.

Ended up switching out the torque for add force. But I feel like this will work better. Thank you.
