supercharging

not doing a whipple but almost the same, im putting togheter a lysholm screwblown 340, there is a few ways of doing it.
use an adaptor on a regualar singelplane intakemanifold,will look alitle odd but works if you can live with the height, there is two obstacles one is that the blower will endup sitthing kind of high due to an Z-shaped adaptor to move the blower forward since these blowers have the outlet in the front of the case and the distributor gets in the way.
you could probably use a indy modman manifold with an adaptorplate this is probably the easiest way i would think but have not measured it that the plenum may be alitle to narrow compared to the outlet of the blower.
you could make or have someone make a custom blower intakemanifold made for your application a few diferent ways either build a fitting plenum that fitts a cut up old singelplane manifold, you could have a custom sheatmetal intake manifold made up by someone good at farbicating. last option is a custom billet intake manifold cut out from a big single piece of aluminum,not cheap in any way unless the mechanical worksshop has a slow period and realy thinks it would be a fun challange doing it this way. beaware the piece will be about 88 pounds before you start cutting it and the right grade of aluminum is not cheap..

my choise ended up being the last option a 88 pound piece of billet, will hopefully get the manifold pretty soon, the machine shop has started working on it atleast. glad the guy thought it was a cool challanging thing to try:)
