A. Install Vortech carburetor enclosure (if not
already completed) assembly #8M205-012
included in this kit. Instructions are included
in the enclosure assembly.
B. Locate the 4GP112-040 discharge assembly.
Using the supplied gasket and 5/16-18 x 3/4"
socket-head screws from the carburetor
enclosure assembly, secure the 3/5" alu-
minum flange to the carburetor enclosure lid.
C. Install the 3/5" x 2.75" 90° elbow (7S350-276)
between the supercharger discharge and the
3.5" aluminum flange previously installed.
Trim the ends if necessary for best fit. Secure
using a #44 and #56 hose clamp.
6. DISCHARGE DUCTING/CARBURETOR ENCLOSURE
NOTE: OPTIONAL: Due to the many possible con-
figurations of intake manifolds (with regard
to carburetor flange height) a carburetor
spacer may be required to obtain the neces-
sary height for proper supercharger and dis-
charge duct alignment. As an option, the
carburetor enclosure cover may be turned
around so that the inlet is facing the passen-
ger side of the vehicle. This may be desir-
able on some vehicle applications with tall
intake manifolds or for vehicles with other
clearance issues. (See Figs. 6-a, 6-b for
more detail.)
1. This optional discharge arrangement
requires the supercharger to be sent into
Vortech for a volute exchange to a straight
discharge unit (a curved volute is originally
supplied on the supercharger).
2. An extended discharge elbow must be pur-
chased from Vortech (#4GA012-021).
3. Also a discharge elbow must be purchased
from Vortech (#8M012-012).
4. Routing of the fuel line inlet to the rear of
the enclosure must also be performed.
NOTE: The 7S350-276 is made to be trimmed in
order to fit, allowing for various intake
manifold heights.
