that's what I'm talkin about. The little air molecules get thrown around by these ribs that line the bbypass valve body. They get banged around and confused. I, also am confused by the entire apparatus. Where did these engineers want the air to go? How did they expect the air to flow? I only know one thing. Pressured air hates sharp angles. I'm just wondering if anyone has mangled thier dual stage IM and what was the outcome. Ohhh I'm going to take action. I donot care if I am wrong. I can't stand looking at this bypass do-hickey wall of inhibiting ribs and double small plenum openings.
