6. SUPERCHARGER INSTALLATION
A. Attach the oil drain line to the supercharger
and secure using one of the #8 hose
clamps provided.
B. Lower the supercharger onto the mounting
plate installed on the engine.
C. Loosely start the 3/8” X 1 1/4” bolts with
washers through the mounting plate and
into the supercharger gear case. Tighten in
steps.
D. Attach the oil drain line to the fitting
previously installed in the oil pan and
secure using the supplied #8 hose clamp.

NOTE: The oil drain hose must maintain a
"Downhill" routing always. "Uphill
routing", dips, kinks or restrictions
in the drain hose may cause
supercharger seal failure
NOTE: Some applications (depending on
intake manifold height) may require
the reclocking of the supercharger
volute. If reclocking is required for
your application, loosen and
remove the six ¼-20 cap screws
and retaining plates that hold the
compressor housing (volute) to the
gearcase. If the compressor
housing does not rotate freely
relative to the gearcase, DO NOT
FORCE IT. SERIOUS
SUPERCHARGER DAMAGE MAY
OCCUR. The machined mating
surfaces are designed to prevent
pressurized air from escaping and
have minimal tolerances. If the
housing will not move or is very
tight, contact Vortech Engineering
immediately at (805) 247-0226 and
ask for our service department for
further assistance.
