I did use Nitrous, 950 psi, -4 "race line", 150 jets. It came out evenly from all 8 orifaces. Rock mention that the old plate had two spereate passages and the new ones are all tied together. Maybe you have an older plate? How long have you had yours? I just picked mine up about 6 months ago.
Sounds like a possibility. I'm sorry for debating this in an open thread but I feel like the NX plate has an awesome distribution pattern. I wish someone would do a "plate shootout" and see which plates actually make the most power utilizing the same jets across the board.
With all of the lean conditions (certain cyliders get leaner than others) that people experience out there one of the biggest influencing decisions for me is nitrous distribution. If you have a plate (either EFI or Carb style) you should really look for something that has the "best", most equal spray pattern out there. I feel that the perimeter plates do a great job of directing nitrous equally to all of the ports on an intake. NXRicky mentioned that the NX Gemini plate were designed off of a Edelbrock Victor Jr intake, which leads me to believe that the Gemini would be the best option for the original poster of this thread. Obviously everyone has an opinion of what they feel is "best". I have seen the NX first hand on an intake while spraying nitrous and felt that it did an awesome job covering all of the port. I can't speak for the other brands mentioned but I do know what intake the Gemini was designed around.

mine needed a little modding, but sounds like the new one is all better.
if i had to buy a new plate, i would for sure use the NX one again. im happy

You should always flow ANY plate on YOUR intake. Each intake has little differences it. Castings are not perfect.
The overall effect of using air or nitrous yields the same results for testing. Air is a simple quick check so you can feel where the air is going, or Nitrous and you can see where the nitrous is going. IF the intake is on the engine using nitrous makes it very difficult to see what is going on. If the intake is on the work bench you see it much easier. But be careful nitrous burns hurt like hell. And that stuff can fly up and get into your eyes, which really sucks.
Ray is correct with spray bars being taylored to each intake.

Actually I did per your & Rick's recommendations and found it to be very equal. Well, from what my eye's and my buddie's eye's could see. I have no other form of measuring device. I tried as you see it pictured with the carb on, then carb off and then just the plate being held by hand and everytime it flowed about as equal as the eye could visually see. I wouldn't think it would really make a difference as the jets that you use would be the final "limiter" or "restriction" of flow? Isn't that the point of the jets, to limit the amount of nitrous being fed into the plate? There is one jet on each fitting and they are of the same size.
I hope rick doesn't mind but this came from his pm. Is it possible that you have an older design plate? Keep in mind, I will not be going over a 200 shot so maybe it won't be as obvious?

I think you will be fine if its the plate I designed. Here is how you can tell...
Look at the bottom of the plate where the nitrous and fuel discharge ports are. You should see 2 nitrous and 2 fuel holes over ever side of the plate, for a total of 8 and 8.
Then take your fuel lines off, and remove the jets. Take an air hose and blow into 1 jet fitting, and see if you feel air coming out the other one. If it does it has a common channel for that one all the way around. I would do this test on both nitrous and fuel.
You should still dry fire it to confirm the nitrous is going down the runners. Dry firing you can use pressured air as well and reach your finger in there and feel where the air in blowing. DONOT USE YOUR FINGER IF SPRAYING NITROUS IT WILL HURT REALLY FREAKING BAD.
Remember you are confirming where the nitrous/air is going, not the fuel channels. Those should be in line and blowing across the plate. The nitrous is what drives the fuel down the runner.
That intake should be PERFECT for the plate. Thats the one I used for port locations, but still check IT. Edelbrock as any casting can move around in the casting process.
hope this helps

Glad all work out and the quick descrip. helped out.
That description was for a plate I designed before I left NX. IT was really different from the first billet plate, or the old school tube plate. Best reason to check and flow what ever plate one gets.
