Race-Tuned Power

The 9.0 liter quad cam, four-valve 1650 delivers Godzilla-like power throughout the RPM band. It is based on the same four valve technology with quad cams and dry sump efficiency as its consumer siblings. Larger turbochargers, packed with an improved compressor wheel design, provide greater airflow for enhanced power and torque. Racers appreciate Mercury Racing’s proprietary pulse-separated exhaust tuning which keeps turbos “spooled up,” virtually eliminating throttle lag and low-end torque deficit.
