Plenum Volume

Ops! Confused manifolds there! Read wrong. Any clue on the volume on the Weiand?
Ok, now you're confusing me. The Weiand is, from what i could find, is 549 cubes. I rough measured at 522, so it's in that neighborhood. I have no idea what the indy is, but like I said, it may still be a better way to go for me and will likely perform better.
