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 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 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 15,000 miles and spark plug wires every 50,000 miles or earlier.
