well with 120hp shot going in, I'd hope to God you tune it!!! Also, from day one I've heard that N2O likes compression.
I'm planning on runningt he bottle. Except I guess a little bit more on the 'dangerous' side. Single nozzle wet kit. I'll probably only go up to 75hp.
Dom,
I"m not aware of a direct port dry kit. The pic you speak of was a wet kit.
