How to Increase the Length of the Partical Trail?

I have a main swirl which is in the middle then I have an outer swirl which speaks for itself. Two things I can’t figure out is how to increase the trail/path length of the outer swirl so it can go further up on the Z axis. The other thing I am trying to figure out is how to make the swirl tighter together if that makes since. Basically I want a semi-stretched out slinky effect instead of a super stretched out slinky.
