Twin Rotor Design
This is the same unit employed by OEM manufacturers such as Jaguar, Mercedes, Ford, General Motors, Toyota, Nissan and others. We chose it for the same reasons they did - excellent peak power coupled with superior low end and midrange. As you leave idle the STILLEN blower is making gobs of power and torque before the centrifugals and turbos spool up. On the street or track, this is a faster and more user friendly system. Maintenance is minimal.
The STILLEN engineering team worked intensively on this project for nearly a year before the first unit was sold. How detailed an undertaking this was can be illustrated in the intake plenums. Several designs were tested. The end result optimizes air flow, fuel distribution and efficient power production. It also provides for the intercooler. The production of the plenum is a multi step process. First the pieces are cast using a STILLEN developed mold. Each piece is then deburred in the STILLEN machine shop. It is then sent out for heat treating. After heat treating it then returns to STILLEN for final machining. And this is only one of several hundred parts that comprise the STILLEN supercharger system!
The STILLEN supercharger is supplied to you or your installer fully tuned. Additional fuel, when needed, is supplied via 8 additional injectors that are mounted in the intake plenum. It is regulated via an electronic unit that is factory set for your vehicle. This also modifies the timing map to optimize it for the supercharged engine. Also included in the kit is a larger fuel pump and the additional injectors. To make installation easier STILLEN has developed a plug and play wiring harness. What used to take 3 hours of wiring now takes 5 minutes. This also ensures that installation is much smoother with less chance of installation errors.
The result is a faster, more fun and dependable unit. The STILLEN supercharger equipped VK56 has a split personality. On the one hand it has the acceleration of a rocket sled - it's fast enough to get you into or out of trouble. On the other, it is well mannered and can be driven normally around town or on the freeway. In normal driving, gas mileage is minimally affected.

About STILLEN Parts & Accessories
Steve Millen Sportparts, Inc. and STILLEN humbly started their race to the front of the pack in 1986. Starting with aftermarket mini-truck appearance packages, we quickly found ourselves fulfilling customer's requests to build products for other vehicles such as vans and full-sized trucks.
With that came performance parts, suspension pieces, and upgraded brake products such as big brake systems. Capitalizing on his racing career, and knowing what it took to make sports cars perform like no other, it was only natural for Steve Millen to branch out into the import car scene. Over two decades later, we offer a full array of products encompassing styling, performance, handling, and braking products for just about any car, truck, or SUV.
