b7 im vs z6 im

[boud92si]

i have the b7 port match and bore 60mm. now the z6 im is on my car and i see z6 has oval runners and b7 round. now is the z6 going to flow better still? and how much of a differance is there

[transzex]

clean up the Z6, it will flow more.

esp. above 6000 rpms.

thanks man but why is oval better than round.. more volume?

[transzex]

more flow, less choke.............

The D15B7 needs nothing bigger than the Z6 mani, unless your getting WILD, aka Bisi style.
