Please take a few moments to review this manual thoroughly before you begin work: Make a 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 offi ce 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 fi re
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 fi ttings 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. 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 fi nish your installation and road test your vehicle, please fi ll out and mail in the limited warranty card, so we
can add you to our fi les (this is important for your protection).
A new GM fuel fi lter is recommended at the time of supercharger installation
Stock spark plugs and stock plug gap is recommended
