Iv researched this thing to death basically. Velocity stacks dont really help air go into an engine vrs volumn. The larger volumn the runner the higher its tune. So if you flare it making a stack you get more power on top and less on bottem.
Now you can make air inducers which dont flare the pipe at all making its volumn the same. Its nothing more then a ring around the edge so air can come in around the edge easier. These are worth some truly free ponies.
Its just whenever i try to do anything on a contour forum i get nothing but flack and its really irritating. I only get it here too thats the wierd thing. Sorry for snapping at you guys
