This is an older Compucar bottle, bought in 2004 I think. Can anyone tell me how much nitrous you can spray w/ this valve before it becomes a restriction?

edit...OK, so right after I posted this, I called Compucar to see what they say. Should have just called them first, but oh well. Ernie says this thing will flow 1,000 hp if I needed it to. Says they use a 5/8" siphon tube compared to a 3/8" tube used in the NOS brand bottles. Pretty sure he said 5/8".

You hear a lot of things from people about some valves not flowing as much as hi-flow valves and whatnot. My other bottles are NOS bottles w/ the 45° handle and hi-flow valves.
