Hack request - SP fuse distance and Blast radius

Hey,

I have been working on a SP mod for a while now. I am trying to create an explosion with a blast radius of 500k (impulse looks to work, just no real damage on the solars). looks like 10k s the cap.ideally I want everything with in 500k to be destroyed. Also I found the hack for MP fuse solar distance, I was wondering if there was a way to do it in SP?

Thanks

Jer
