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.

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 at least 3,000 miles. Never attempt to extend the oil change
interval beyond 3,000 miles, regardless of oil manufacturer's claims; 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 at least every 15,000 miles and spark plug wires at least every
50,000 miles.
