Paxton supercharger systems are performance improving devices. In most cases, increases in torque of 30-
35% and horsepower between 35-45% can be expected with the boost levels specified by Paxton Automotive.
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. Paxton
Automotive 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 Paxton prior to using this product.
4. Always listen for any sign of detonation (pinging) and discontinue hard use (no boost) until the problem
is resolved.
5. Perform an oil and filter change upon completion of this installation and prior to test driving your vehi-
cle. Thereafter, always use a high grade SF rated engine oil or a high quality synthetic, and change the
oil and filter at least every 3,000 miles. 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 one year or 15,000 miles with
original heat range plugs as specified by the manufacturer and reset timing to 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 20,000 miles.
