[QUOTE="dan filipi, post: 103038, member: 54"] They're out there. I think Joe has a source. I think pretty certainly it's best to build from the type 4 plenum. It's design is a big boost in the way it directs airflow. Yes Aapple, I agree different designs will not lead to a one design that's repeatable, however my original intension with mine was to prove or disprove if 1" runners were too small. Which in fact they are not too small. This fact has led to a major conclusion that full size runners over approx 1-1/8" are too big if there isn't any device in the runners to speed up flow. In itself this was a major confirming step in the direction this mod needs to go and confirmed larger runners will not dial in properly. Yes they will run but run efficiently? No. My tests have been part of the R&D process to find what works and what doesn't work. There are very subtle differences with all aspects of this mod which add up, one affects the other. [/QUOTE]
