Important Installation Notes:

A. This system was designed to fit on engines equipped with a “long” water

pump. Vortech includes a 3-groove assessory drive crank pulley (for use with a “short” water pump, a custom accessory drive crank pulley and spacer will be required).

B. For engines equipped with power steering, a remote reservoir (GM “type 2”)

style pump will be required as well as an optional Vortech power steering pump bracket and pulley assembly. Depending on the vehicle, power steering lines may require fabrication.

Installation Instructions

PLEASE READ CAREFULLY

This kit should only be installed by qualified mechanics. It is imperative that

the correct air/fuel mixture be maintained at all times. This kit is to be supplied to competent engine tuners for their completion by the addition of, and tuning of, an appropriate carburetor unit and fuel pump.

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.

Vortech Engineering is not responsible for engine damage. Installation on new engines 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 or lower than 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 operating the vehicle. Thereafter, always use a high grade SF rated engine oil or a high quality synthetic, and change the oil and filter every 3000 miles.

6. Before beginning installation, replace all spark plugs with one to two step colder heat range and reset timing to no more than 26°-28° total. (Always follow the procedures indicated in the factory repair manual.)
