"Modified" NOS 78mm plate kit need some opinions on things Quick rundown of what's going on. I have a 97 "LT" style car. I swapped a 98 ls shortblock into it. Has 853 heads, ls6 intake, head studs (not a typo) and a 224/230 on a 114 LSA cam and basic upgrades (PR, Springs, Timing chain etc) PS longtubes and 3" ORY into a corsa catback. Car has a VA Speed built FMVB th350 with an FTI 3600 nitrous stall in it. 3.42 gears and 26" ET streets. As of right now I have a NX nozzle kit on the car, but I upgraded the solenoids to some Induction Solutions trashcans (for later use) because they had a good sale on them a little while back.
I got a NOS 78mm plate for next to nothing and because this car is pretty much put together with stuff I had laying around, I care very little about it's well being
I know that MOST people say that plate is good for 175ish hp, some say you can get 200 out of it. I'm running a -4an feed line, and from the solenoid to the plate is -3an (18" long) on the nitrous side of the kit. On the subject of line size and nitrous flow, I was thinking of just sticking a jet that I drilled out to the max it can, to seal the line and pretty much run as much nitrous through the plate as I can. With essentially no jet restricting the nitrous flow, how much do you think the plate and/or line will allow me to flow through there? I've searched quite a bit with no turn out on how much an -3an line can actually flow. I know length plays a factor in flow so I guess my 2 questions are..
1-How much can a -3an 18" long line flow?
2-Will the plate max out before the line itself will?

here is a jet chart that one of the NOS/ Holley tech guys sent me for my same plate when I asked them about jets for a 200 shot. I have not tried it so use this information at your own risk.

I had originally wanted to "open flow" the kit, but decided to work my way up on the tune up. a .070/.042 jet made 192hp/165tq at the rear wheels (stalled auto) on 22* of timing. planning on upping the jet until no more power is made due to the limits of the -3 line.
