there was an interesting article in hot rod mag[link on the net]that had a graph for intake cfm vs exh cfm and the tube size needed.1.5 cfm per hp intake made 2.2 cfm exh and it gave tube size for hp per cylinder.

Thats the program I use... with tons of dyno time I
found it to be very good data.... I would have answered
your question but I was on vacation.... there are a
few things that you would LIKE to do IF you can...
try to get 1 cylinder volume in the primary tube before
you hit the first tangent point... TRY to use the
biggest radius bends that will fit
