Active Autowerke E46 M3 PRIMA PLUS + SC with 600 horsepower UPGRADE KIT
As producer of one of the finest working supercharger systems for the BMW E46 M3, Active Autowerke is
proud to introduce the PRIMA PLUS supercharger system capable of exceeding 500 WHP running on
pump drawn 93 octane. The PRIMA PLUS is an upgrade kit to the existing PRIMA supercharger system
designed to create MORE horsepower.
In collaboration with Frank Smith of Tuning Tech FS, the Prima PLUS SC kit has evolved as a fantastic
performer. With numerous dyno runs under countless hours all monitored through careful Data Logging and
Lean/Rich evaluation, this PRIMA PLUS supercharger kit is ready for the BMW enthusiast.
Special thanks goes out to Frank Smith and the guys at Tuning Tech,FS, a Active Autowerke Dealer in the
Special thanks goes out to Frank Smith and the guys at Tuning Tech,FS, a Active Autowerke Dealer in the
Maryland area to help launch this supercharger system.
The PRIMA PLUS is a centrifugal design supercharger using a conventional fixed drive pulley, but unlike it's
predecessors, the PRIMA PLUS also has variable boost settings of 9.0 psi and 9.5 psi to help attain the power.
A first in the BMW forced induction industry.
For easy comparisons, here is where the PRIMA and PRIMA PLUS + stands when measuring rear wheel horsepower.
A stock BMW E46 M3 is around 265 WHP.PRIMA SC makes 425 WHP. PRIMA PLUS SC makes 500+ WHP.
Customer impression:
"...I intend to go to race fuel (104+) in the spring when I can drive it more.
So far the acceleration plants you into the seat. 1st and 2nd gear have the
rear tires searching for grip and I am running a 275 R compound tire. The
car feels alive and the power band is exceptionally characteristic of the
original power plant but just more power everywhere. There is no lag in
power delivery and is easy to modulate in partial and full throttle scenarios...."

How Does It Work:
Running without a front mounted intercooler, the PRIMA PLUS + relies on Water/Methanol and precise tuning to
make it happen. When activated by the flip of a switch, the system develops 9.5 psi of boost and 500 + WHP.*
The Water/Methanol system combined with proper software tuning performs flawlessly, but if a problem arises
such as a low WA/Meth fluid level, excessive detonation, etc. there a immediate safeguard built in.
The system will automatically default back to the 6.0 psi level to prevent any damage to the motor.
Now you can enter the F.I. realm with a proven company known for reliability and proven performance.

Good value for the money.
Size: 9.5 Wide, Color: Beige
Comfortable right out of the box. Great style and well made. The more you wear the softer they get but maintain their overall appearance.

Comfortable fit for slip-in fabric shoes
Size: 14, Color: Black/Black
My first experience with Marc Joseph. I typically purchase dress and casual work shoes from Florsheim and occasionally Rockport. I'm giving these four stars because the initial fit and feel appear solid. Depending on the shoe brand I wear a size 14 or 15. My feet are slightly wide but I don't alway need wide fit. These size 14 fit well with wide enough toe box. I've tried slip in shoes before and they just don't feel right. These somehow work and there is no heel slip. My only reservation is the high lip on the heel for slip-in and hope they dont catch pant hems. I gave 4 stars because I'll have to determine durability. Granted they are a light fabric shoe with a soft rubber tread. I'd like them to last for at least 6 months..and use them for business casual work wear during warm weather.
