Powerful, Reliable and 50 State Legal
Proven on the streets and strips of the U.S. over the last 3 years,
STILLEN makes the most reliable forced induction kit
for the VK56. Our Stage 2 kit is the first and only
forced induction kit to gain CARB approval; it is
legal for street use in all 50 states!
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.
Engineering
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!
Tuning
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.
Results
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 its 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.
