hey guys, thinking of making my own blower intake for a flathead. I have a few ways that I am thinking of doing this in my head. My blower is an eaton (cheap) that has a farely small mount surface. I Could modify a four barrel manifold to work fairly easily. the single plane unit that speedway made/makes (may be discontinued??) looks like it was made to be a blower manifold, not a flathead four barrel!! they want a lot of money for them IMO..... but notice there is no divider in the middle?? ask anyone how well their flathead four barrel manifold worked when they milled out the divider! option two is making my own out of steel like below but thats a lot of plenum! or something with a much smaller plenum volume like the navarro. the difference being the runners come in to the plenum from the front and back instead of the sides/underneath. this makes the real question how much does plenum volume matter on a supercharged flathead?? is it better to keep it small?? I know there are calculations that can be done on an NA motor to optimize plenum and runners but I'm not sure that any of this applies when I bolt on a huffer!
