I purchased a Supercharger (Stage 1 - 1989 model) from you 1-2 years ago, really happy/fantastic! Gary M
I am extremely happy with the SC kit the quality and design are excellent. When ever someone sees the SC installed on the car they are amazed at how clean and well designed the kit is. Not to mention that the car can eat eat 99% of cars on the road for lunch. Dana J
My 1988s4 5 speed has now been supercharged (stage 1) for 3 years and over 22,000 km. I am still very happy with the modification. Oh, and there are no rattles or whines from the engine or the SC. Chris G
FACTORY NEW SUPERCHARGER KIT IN SATIN TRIM COMPLETE
Application: 1986.5 to 1995 Porsche® 928 all
Easy Installation! Our kits come with everything you need to do the complete installation yourself. The Stage 1 kit is our easiest kit to install because it does not require a separate intercooler system. Plus, because the Raptor V supercharger used in these kits is self-contained - with permanently lubricated bearings - the need for oil lines to and from the engine is eliminated. Typical installation time: 8 hours complete!

The 928 Motorsports Stage 1 Supercharger kit for the late-model Porsche® 928 will provide more horsepower and torque and do it efficiently, reliably and quietly with no loss of drivability or daily ease of operation. You will substantially increase your 928's acceleration and fun-factor! This rugged supercharger's precision construction and the exclusive ceramic-coated impeller assures full high speed performance at all RPM's along with outstanding reliability and quiet operation.

Dyno-proven Results: This Supercharger kit installed on a 1991 Porsche® 928 with manual transmission (photos below) produced 413 HP at the tire and 475 HP at the engine, up from the stock numbers of 271 HP at the tire and 312 HP at the engine.
