Before beginning this installation, please read through this entire instruction booklet and the Street
Supercharger System Owner's Manual which includes the Automotive Limited Warranties Program and the
Warranty Registration form.
Vortech supercharger systems are performance improving devices. In most cases, increases in torque of
30-35% and horsepower of 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 vehi-
cle. Thereafter, always use a manufacture-rated, high grade engine oil or a high quality synthetic, and
change the oil and filter every 3,000 miles or less. 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 10,000 miles with
original heat range plugs as specified by the manufacturer and reset timing to factory 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 at least 15,000 miles and spark plug wires at least every 50,000 miles.
