Wow that's some airspeed, that's close to mach .5, you're starting to get some compression effects in the port at that speed. Mach one is ~1090 fps, in fact compressiblity effects start at around 340-350fps. Since all the air is confined to the port and doesn't bleed out it's practically always in "ground effect".
I wouldnt worry about the nitrous. Worry about getting the most NA out of it. Its not a nitrous race engine that will be seeing hit after hit. Its an idea at this point and anything that I do spray will be minimal if even needed.
If adding NOS. Concentrate on the short turn side of the throat. The efficiency doesn't need to be the same all the way around. You can open that area to 95% for added flow with NOS without sacrificing N/A performance.

What is the typical cause for port flow to go down at high lifts? Loosing it around the short side?
Throat and ssr width, arc shape. I would think. Cause ssr to have issues. Thanks

I just did 2 days experimenting on exhaust throat ratios. Stay tuned! Long and boring!
