MERCURY RACING 662SCI STAGE 1

The Whipple Stage 1 system is a computer recalibration that increases the maximum power by more than 95HP* and 90 pounds of torque*. Whipple also increases the low rpm power range for a significant decrease in plane time and a noticeable 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 4-7mph**
• 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
