I have an adapter from my 4150 manifold to the 4500 dominator carb that im running. My question is, does the nitrous plate need to be directly below the carb or can i install it below the manifold and the spacer? If my thinking is correct, it shouldnt matter because the same amount of fuel/nitrous is going to introudced into the engine so it shouldnt matter where its at?
First the further away from the valve you inject your nitrous the Harder it's going to hit, and shock your system.
Second is if you're running a 4150 to 4500 adapter having spray bars at the bottom will have them in the way and can cut off some of your air flow. It's really a double edged sword.
