MERCURY RACING 662 SCI STAGE 2

The Whipple Stage 2 system boasts even more power than stage 1 by coupling a Stage 2 performance calibration with a Whipple stage 2 supercharger pulley. The Whipple Stage 2 system also includes a simple bolt on water system upgrade to increase system pressure and intercooler efficiency. This system helps boost the engines output by more than 170HP* and 130 pounds of torque*. Whipple also increases the low rpm power range for significant decrease in plane time and a healthy gain in acceleration. The factory rpm limiter is also increased, giving customers the ability to greatly increase top speed MPH while running original props. The stock RPM limit of 5400 is modified to 6000rpm where peak power ends. 

Key features:

• Hi-performance PCM calibration with MPH gains of 6-10mph**
• Intercooler water re-route
• Increased horsepower for increased top speed MPH
• Increased low-speed torque for decreased plane time
• Increased low, mid and high speed torque for better acceleration and throttle response
• Increased spark at low and mid speeds for increased engine efficiency
• 6000 RPM limit vs. stock 5400 RPM limit giving increased propping range and increased horsepower
• 91 octane safe (RON+MON)/2
• Stock idle, starting and drive-ability is maintained

*NOTE: PCM'S MUST BE SENT TO WHIPPLE SUPERCHARGERS FOR CALIBRATION SERVICE ALONG WITH RECEIPT, NEW PCM'S ARE AVAILABLE UPON REQUEST. TURN AROUND IS NORMALLY 7-10 DAYS.

**Power levels can vary from engine to engine. Whipple’s performance results were under controlled conditions. All applications can vary.
