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 addi-

tion 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.)
