Question High ISP Turbopack

[ikrase]

Is there a way to change the UMMU turbopacks so that they have a higher ISP/longer flight time? Has anyone made a super turbopack mod or is there a way to edit it?

I used something like two-stage turbopack once.
One on the back, second grappled in hands. When first stage burns out, drop it and transfer second one from hands to back. That was fun :thumbup:

I've done that a lot. What I want though, is a turbopack that will last much longer than the original one.
