BOOST REFERENCE PORT
Blow-Thru applications do not require modifications to the boost reference port. Draw-thru applications
require a few modifications to the throttle body. Locate the boost reference port on the throttle body.
It is located on the lower right corner of the throttle body on the same side as the IAC motor (back of
the throttle body), and remove the plug. Turn the throttle body upside down. Using a small drop of
Loctite on the plug, install the plug into the threaded orifice next to the throttle blades. Install A 1/16
pipe to hose fitting into the boost reference port on the throttle body. The boost reference port on
the throttle body should be referenced below the supercharger directly off of the manifold, or can be
split off of the boost gauge reference line (Figure 4).

INSTALLATION
1. Install the new gasket and place the throttle body on
the intake manifold. Make sure the throttle body is
square on the intake and the linkage moves through
closed throttle to wide open.
2. Secure the throttle body by tightening the four
retainers evenly. Do not over tighten.
3. Transfer the linkage hardware from the carburetor to
the Atomic. Any transmission brackets should also
be transferred to the Atomic. A throttle return spring
must be used (Figure 5).
4. Install the new air horn gasket.
5. Determine which fuel inlet and AN-fitting best suits
your application.
6. MSD supplies two -6 AN style fittings for use on the
throttle body fuel inlet. Both use ‘push-lock’ style inlets
to connect to the fuel hose and do not require clamps. Page 8 details the installation of MSD's push-
lock fittings and hose.
Note: Not all fuel lines are rated for "push lock" installation.
7. Install the fitting to the throttle body.
