Product Description

Powerful, Reliable and 50 State Legal (05-06 Models – Others Pending)
Proven on the streets and strips of the U.S. over the last 3 years, STILLEN makes the most reliable forced induction kits for the VQ powerplants. Our Stage 2 kit was the first forced induction kit to gain CARB approval; making it legal for street use in all 50 states for 05-06 models!

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. Check the comparison dyno chart – 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 is powder coated. 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 a 7th injector that is mounted in the inlet tube. 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.

The result is a faster, more fun and dependable unit. The STILLEN supercharged VQ40 has a split personality. On the one hand it is 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.
