MERCURY RACING 600 SCI STAGE 4

The Whipple Stage 4 system boasts even more power than stage 3 by coupling a Stage 4 performance calibration with a Whipple stage 4 supercharger pulley and Whipple stage 4 camshaft kit. The Whipple camshaft works well with all stock valve train for a very simple swap. The Whipple Stage 4 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 290HP* and 225 pounds of torque*. Whipple also increases the low rpm power range for significant decrease in plane time and a stunning 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 15-20mph**
• Intercooler water re-route kit
• High flow intercooler fittings (10AN)
• High-flow billet flame arrestor
• High-flow 120deg thermostat
• 10-Rib Gates supercharger belt
• 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
• Stage 4 camshaft to produce more power throughout the rpm range
• Colder NGK Racing spark plugs
• 6000 RPM limit vs. stock 5400 RPM limit giving increased propping range and increased horsepower
• 91 octane safe (RON+MON)/2
