@ sohclubkid I think you have your dry and wet systems mixed up.
Dry is where nitrous is injected with fuel directly into the intake ports where the injectors go. Wet is injected with the fuel somewhere in the intake track. It is safer to have a higher dry shot than it is to have a high wet shot because nitrous and fuel soaks the intake track, throttle body, and intake manifold leading to a higher chance of nitrous backfires caused by residual nitrous and fuel leaking from your intake track into your cylinders when not at WOT. This is what causes blown engines. Dry (also known as direct port injection nitrous) will have no residual nitrous and fuel left in the intake track and is therefore safer.
20 on wet, 50 on dry. I wouldn't go higher than this because nitrous on a Honda shouldn't be used for more than turbo lag kill or a little more go. It shouldn't be used as a main source of the engines power.
