Congratulations on selecting the best performing and best backed automotive super-
charger available today... the VORTECH ® V-2 ® SUPERCHARGER !
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 and 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 92 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
synthetic, 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 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 15,000 miles and spark plug
wires at least every 50,000 miles.
