Guides to all I did will be on the new website. The only one I need to write is the PC expansion one, which I did today. All the modifications were pretty straightforward. The Arctic Blast is pretty easy to modify, but you won't get great performance out of it because it's so small. PRVD is easy because you don't have to do any cutting. All you have to do is seal off a hole. Changing the flood nozzle is as easy as removing the case and sticking a 1/2 inch male threaded adapter onto the nozzle (this was too weird of a coincidence). PC expansion wasn't that hard, but it was more involved than the other modifications. I cut a hole in the case to let a longer clear PETG pipe stick out the end. This allows the PC to expand fully for once. The PETG tubing is clear, so it also acts as a PC gauge. Another side effect of PC expansion modifications is improved power. Here the PC can expand more in length, and a small increase in pressure will be seen. If I changed it so the PC expanded more in diameter, a more noticeable increase in power would be seen.
Another great thing about PC expansion is that I don't have to worry much about pressure cracks. Pressure cracks usually only occur in CPS water guns when the PC has expanded fully and has nowhere else to go. The PC can expand pretty long now.
I haven't tested the gun out yet due to the cold, but I'm sure it'll work nicely. The nozzle and PC expansion modifications were the most worthwhile, so much that I would like to see them become more common.
Some pictures are below.
