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.)
