STILLEN 2009-2011 Nissan 370Z [Z34] Supercharger Tuned System [Polished] - 407770P

The STILLEN Polished Supercharger Tuned System (407770P) transforms your 2009–2011 Nissan 370Z Z34 into a high-performance powerhouse. Engineered with precision, this turn-key, bolt-on supercharger system delivers a linear, driveable powerband, giving your 370Z up to 400 wheel horsepower (typical range 380–450WHP).

At its core, the system features a polished Vortech V-3 centrifugal supercharger, integrated with a custom air-to-water intercooler. The intercooler keeps intake air cool at the engine entry point, maximizing performance while maintaining engine longevity. A front-mounted compact heat exchanger optimizes airflow to all critical components, ensuring consistent performance even under hard driving conditions.

The cast aluminum intake manifold has been redesigned for longer runners and a larger plenum, increasing airflow and torque. The Vortech V-3 supercharger includes a self-contained oiling system, quiet V-belt design, and future upgrade potential. Extensive testing ensures both reliability and street drivability, from low-RPM cruising to track-day abuse.
