On a more serious note, who actually designed it?
What formulas did you use?

With the inlet runners spaced out and the inlet at the end of the plenum the airflow obviously has to flow differently for each cylinder as each effective runner (throttle plate to inlet valve) is of a different length.

How did you cater for this, as ive been looking into the Maths of it and its not that simple at all.......

yet i know of a few people who have made their own and has shown to work well.
Although none of the ones ive ever seen have been tested for flow through each cylinder to ensure they are the same, so potentially some people could be running lean on one cylinder.

Any thoughts?
