Installation Instructions

Congratulations on selecting the best performing and best backed automotive

supercharger available today... the VORTECH® Supercharger!

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

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 2 years or 20,000 miles

with original heat range plugs as specified by the manufacturer and retard timing from 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.
