INSTALLATION MANUAL
Magna Charger
GM 5.7 Liter Engine,
2004-2005 Cadillac CTS-V
Please take a few moments to review this manual thoroughly before you begin work:
Μake quick parts check to make certain your kit is complete (see shipper parts list in this
package). If you discover shipping damage or shortage, please call our office immediately.
Take a look at exactly what you are going to need in terms of tools, time, and experience.
Review our limited warranty with care.
When unpacking the supercharger kit DO NOT lift the supercharger assembly by the black
plastic bypass actuator. This is pre-set from the factory and can be altered if used as a lifting
point!
Caution: Relieve the fuel system pressure before servicing fuel system components in order
to reduce the risk of fire and personal injury. After relieving the system pressure, a small
amount of fuel may be released when servicing the fuel lines or connections. In order to
reduce the risk of personal injury, cover the regulator and fuel line fittings with a shop towel
before disconnecting. This will catch any fuel that may leak out. Place the towel in an
approved container when the job is complete.
Use only premium fuel, 91 octane or better.
Magna Charger systems are manufactured to produce about 20 RWHP
per pound of boost at sea level. High altitudes will produce different numbers.
Our Magna Charger kits are designed for engines in good mechanical condition only.
Installation on high mileage or damaged engines is not recommended and may result in engine failure, for
which we are not responsible. Magna Charger is not responsible for the engine or consequential
damages.
Aftermarket engine recalibration devices that modify fuel and spark curve (including, but not
limited to programmers) are not recommended and may cause engine damage or failure. Use of
non-Magna Charger approved programming will void all warranties. If you have any questions,
call us.
After you finish your installation and road test your vehicle, please fill out and mail in the limited
warranty card, so we can add you to our files (this is important for your protection).
A new GM fuel filter is recommended at the time of supercharger installation.
Stock spark plugs and stock plug gap is recommended

225. Reconnect the negative battery connection
with a 8mm wrench.
226. Attach a short length of hose to the right intercooler manifold barb temporarily and route it to the
mouth of the funnel as shown. Switch the ignition
on but DO NOT START THE ENGINE! Allow
the intercooler pump to circulate the coolant mixture
through the system for a minimum period of at least
10 minutes. This wll purge the intercooler system of
any air bubbles and ensure maximum performance.
After 10 minutes switch off the ignition and and remove the temporary hose from the intercooler manifold. Re-attach the intercooler hose to the manifold
and tighten the clamp securely.
227. Start the vehicle for 5 seconds and shut off,
once again check for fuel leaks and supercharger
belt alignment. Test drive vehicle for the first few
miles under normal driving conditions, listen for any
noises, vibrations, engine missfire or anything that
does not seem normal. The supercharger does have
a slight whining noise under boost conditions, which
is normal.
228. After the initial test drive gradually work the
vehicle to wide open throttle runs, listen for any
engine detonation (Pinging). If engine detonation
is present let up on the throttle immediately. Most
detonation is caused by low octane gasoline still in
the tank. With the ignition on, but the engine not
running, use a straight blade screwdriver to open the
air bleed valve on the top of the intercooler water
manifold. A small amount of air will escape. Close
the valve when fluid comes out. Do this again after
500 miles.
