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 1 year or 10,000 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.

3. Thread in the tensioner bolt until the idler moves 1/4".

4. Tighten the nut securing the idler stud. Tighten the jam nut on the tensioner bolt.

5. Test drive the vehicle and repeat steps until belt slippage is eliminated

B. Engine detonates (pre-ignition):

1. If detonation is detected, the ignition

timing should be set to the bottom of the factory specs (located on the under hood emissions label) by following the procedure in the factory shop manual.

2. For off-road and high RPM use, the ignition timing should be set to 12° BTDC.

3. For emissions legality or if more retard is needed, a boost retard ignition may be installed.

C. “Check Engine” light illuminates

(P0172) after vehicle is driven: This may

be caused by a number of things, but is most likely due to the installation of larger fuel injectors for which the vehicle may not be able to trim out enough fuel. This

code does not affect the vehicle’s driveability and may be ignored. To fix do the following:

1. Disconnect the battery for 30 minutes to clear the code.

2. Remove the fuel pressure regulator and drill a .075" hole through one side of the body as shown in Fig 19-a.

3. Purchase and install a “Maxflow Fuel Pressure Optimizer” per the instructions supplied with it.

4. Turn the adjustment screw counterclockwise until it stops.

5. These two modifications should lower the fuel pressure at idle to ~30psi (from ~42).

6. Re-connect battery and test drive.

NOTE: If after completing the above steps,

the check engine light is still on, complete the “Type R” steps outlined in Section 5-a (steps 1 through 5).
