What the hell did you just say? Try rewording and I'll consider answering your question when I understand what you're saying.Originally Posted by 01rbuild
If my deciphering of your post is correct, you don't really know what a "plenum" is. It's not the entire intake manifold, it's the "chamber" that separates into the runners that lead into the cylinder head. The size of the plenum (and length/diameter of aforementioned runners) affects powerband quite dramatically.
