Default Sizing Nitrous Feed line..4AN or 6AN

For a typical 15' main nitrous feed, does anyone have rough flow HP ranges on the different sized braided hoses?

I am going to run two 10lb bottles this year for a 200 shot, with a 4An from each. I dont think I have a very good valve on my NX tanks due to the fact that I had some pressure drop from a 125 shot and one bottle.


For Example:
4AN is good for....250
6AN is for 250+to 500..etc

I would say go with the 4an line.. That should work. I would not see any reason it would not work... If you are having bottle issues, I would not think a larger line would help that any. Would only cause more issues. IMO.

as for HP rating, not sure. Have not looked that up, but I do know a few peeps that are running 200shot, and If I recall correctly they are running 4an lines.

A 200 shot is usually the max for a -4 line.
