NEVER ATTEMPT TO ADJUST THE BELT WITH
THE ENGINE RUNNING! Retighten all bolts and
double-check your work.
8.2 Locate the rubber sleeves and the front cross
over tube. Check the inside of the cross over tube
for debris - clean if necessary. Running a rag
through the pipe pulled by a strong wire is a good
way to do this. Install the cross over tube between
the idle air manifold (dummy throttle body now on
the intake manifold) and the supercharger dis-
charge manifold. If you find the rubber sleeves
hard to slip over their respective landings, use
some spray light oil such as WD40, which dries off
to lubricate the situation. Do not use gasoline prod-
ucts or pure silicone products. The best technique
for installing the cross over tube involves putting
the 2.75” diameter rubber sleeve on the super-
charger manifold and the 2.5” diameter sleeve on
the cross over tube, and attach both with clamps.
Then install the cross over tube, starting at the
supercharger end first.
8.3 If you have cruise control, route the factory
vacuum line from the cruise control back to its orig-
inal position, being careful to tie-wrap it away from
the engine belts or radiator fans. Remove the steel
spacer from one of the mounting grommets on
your stock Mazda air box. Use this 13/16” long
spacer and the 6mm x 25mm hex head bolt sup-
plied to secure your cruise control brace to the air
filter base. The bolt will go vertically through the
cruise control leg brace and into the small ledge
with a threaded hole on the air filter base.
8.4 Once the cross over tube is installed correctly,
double-check all your pipe and tube connections.
There should be no loose ends or connections. Do
not over tighten any hose clamps, but ensure that
they are snug. Double check your supercharger
belt for correct tension. If the cross over tube is
pressing too hard against your upper radiator
hose, you can remove 3/4” to 1” from the radiator
end of the hose to allow for more clearance, if you
wish.
Complete step 8.5 before starting your engine.
8.5 CLEARANCES
IMPORTANT! MAKE SURE THAT YOU HAVE AT
LEAST 3/4” INCH CLEARANCE BETWEEN ANY
ENGINE MOUNTED COMPONENT AND ANY
BODY MOUNTED COMPONENT. CRITICAL
AREAS: BYPASS ACTUATOR TO BRAKE LINES
(VERY CRITICAL - The engine “rocks” strongly to
the driver’s side upon deceleration. If clearance is
too tight, your brake lines can be gently deformed
away from the super-charger bypass actuator by
hand. ) SUPERCHARGER OUTLET MANIFOLD

9.0 ENGINE ADJUSTMENTS
9.1 SUPERCHARGER BELT DRIVE ADJUSTMENT
Start your engine and observe your belt drive. The
belt should line up with itself as it passes between
the two nylon idlers. To put it a different way, the
portion of the belt running up to the supercharger
should lay almost directly over the portion leaving
the supercharger and heading toward the power
steering pulley. If the upward run is more forward or
rearward than the downward run, you need to
move your supercharger slightly forward or back-
ward with respect to the crankshaft pulley. You can
now access the two bolts attaching the supercharg-
er’s bracket to the cylinder head from step 6.1 with
an open-end wrench. Loosen each bolt slightly to
allow for adjustment. Start the engine. You can now
move the supercharger assembly slightly forward or
rearward to correctly align the drive pulleys. The
slots in the Supercharger mounting bracket will
allow you to find the perfect alignment for the belt
run. NOTE: Do not attempt to move the super-
charger with your hands with the engine running.
Use an appropriate tool. The best tool to use is a
flat blade screwdriver placed between the forward
bracket bolt and the front inside edge of the brack-
et. Move the supercharger assembly while watch-
ing the belt run the idler pulley. If you have the two
bracket bolts too loose, the supercharger will be out
of alignment from side to side. Make sure the two
bolts are snug enough to just allow some leveraged
movement. Once you have the belt running true in
