Before beginning this installation, please read through this entire instruction booklet and the
Street Supercharger System Owner’s Manual which includes the Limited Warranty Program,
the Warranty Registration form and return envelope.
Vortech supercharger systems are performance improving devices. In most cases, increases in
torque of 30-35% and horsepower between 35-45% can be expected with the boost levels specified
by Vortech Engineering. This product is intended for use on healthy, well maintained engines.
Installation on a worn-out or damaged engine is not recommended and may result in failure of
the engine as well as the supercharger. Vortech Engineering is not responsible for engine
damage.
Installation on new vehicles will not harm or adversely affect the break-in period so long as factory
break-in procedures are followed.
For best performance and continued durability, please take note of the following key points:
1. Use only premium grade fuel 91 octane or higher (R+M/2).
2. The engine must have stock compression ratio.
3. If the engine has been modified in any way, check with Vortech prior to using this product.
4. Always listen for any sign of detonation (pinging) and discontinue hard use (no boost)
until problem is resolved.
5. Perform an oil and filter change upon completion of this installation and prior to test driving
your vehicle. Thereafter, always use a high grade SF rated engine oil or a high quality syn-
thetic, and change the oil and filter at least every 3,000 miles. Never attempt to extend the
oil change interval beyond 3,000 miles, regardless of oil manufacturer’s claims as
potential damage to the supercharger may result.
6. Before beginning installation, replace all spark plugs that are older than 1-year or 15,000
miles with original heat range plugs as specified by the manufacturer and reset timing to fac-
tory specifications (follow the procedures indicated within the factory repair manual and/or as
indicated on the factory underhood emissions tag
). Do not use platinum spark plugs
unless they are original equipment. Change spark plugs every 20,000 miles.
