This package includes a Stage 4 PCM calibration, Stage 4 supercharger pulley, Stage 4 camshaft kit, intercooler water re-route kit, high-flow billet flame arrestor, and high-flow 120 degree thermostat.\u003c\/p\u003e\n\u003cp\u003eThe Whipple Stage 4 camshaft is designed to work with the stock valve train for a simpler camshaft upgrade path. The Stage 4 system is listed to increase engine output by more than 210 HP and 170 lb-ft of torque over stock under Whipple test conditions, or 45 HP and 35 lb-ft of torque over the Stage 3 package under Whipple test conditions.\u003c\/p\u003e\n\u003cp\u003eWhipple also increases low-RPM power to help reduce plane time and deliver a strong gain in acceleration. The factory RPM limit is raised from 5400 RPM to 6200 RPM, giving customers a wider propping range and additional top-speed potential when the boat, prop, conditions, and setup support it. The Stage 4 calibration is designed for 91 octane fuel using the (R+M)\/2 rating method while maintaining stock-style idle, starting, and driveability.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cu\u003eStage 4 Kit Features\u003c\/u\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eStage 4 performance upgrade kit for compatible Mercury Racing 700 SCI applications\u003c\/li\u003e\n  \u003cli\u003eStage 4 high-performance PCM calibration\u003c\/li\u003e\n  \u003cli\u003eStage 4 supercharger pulley\u003c\/li\u003e\n  \u003cli\u003eStage 4 camshaft kit designed to work with the stock valve train\u003c\/li\u003e\n  \u003cli\u003eIntercooler water re-route kit to support increased system pressure and intercooler efficiency\u003c\/li\u003e\n  \u003cli\u003eHigh-flow billet flame arrestor\u003c\/li\u003e\n  \u003cli\u003eHigh-flow 120 degree thermostat\u003c\/li\u003e\n  \u003cli\u003eListed power increase of more than 210 HP over stock under Whipple test conditions\u003c\/li\u003e\n  \u003cli\u003eListed torque increase of more than 170 lb-ft over stock under Whipple test conditions\u003c\/li\u003e\n  \u003cli\u003eListed increase of 45 HP and 35 lb-ft of torque over Stage 3 under Whipple test conditions\u003c\/li\u003e\n  \u003cli\u003eListed MPH gains of 10-15 mph, depending on boat setup and conditions\u003c\/li\u003e\n  \u003cli\u003eIncreased horsepower for improved top-speed potential\u003c\/li\u003e\n  \u003cli\u003eIncreased low-speed torque to help reduce plane time\u003c\/li\u003e\n  \u003cli\u003eIncreased low, mid, and high-speed torque for improved acceleration and throttle response\u003c\/li\u003e\n  \u003cli\u003eIncreased spark at low and mid speeds for improved engine efficiency\u003c\/li\u003e\n  \u003cli\u003e6200 RPM limit compared to stock 5400 RPM limit\u003c\/li\u003e\n  \u003cli\u003eDesigned for 91 octane fuel using the (R+M)\/2 rating method\u003c\/li\u003e\n  \u003cli\u003eMaintains stock-style idle, starting, and driveability\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cu\u003eCalibration Service Process\u003c\/u\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe PCM must be removed and sent to Whipple Superchargers for calibration service. Include a copy of the receipt and any relevant engine, boat, fuel, prop, PCM, pulley, camshaft, flame arrestor, thermostat, intercooler water system, and setup details with the PCM. Typical turnaround time is 7-10 days.\u003c\/p\u003e\n\u003cp\u003eNew PCM units may be available upon request. Verify PCM compatibility, engine model, fuel octane, current calibration, pulley setup, camshaft installation requirements, thermostat requirements, intercooler water system configuration, flame arrestor configuration, and complete installation requirements before ordering.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePerformance note:\u003c\/strong\u003e Power levels can vary from engine to engine. Whipple performance results were achieved under controlled conditions, and all applications can vary. Boat speed, plane time, and acceleration results depend on boat design, propping, atmospheric conditions, operating environment, driver input, and the complete engine package. MPH gains are helpful reference points and are not guaranteed.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eApplication note:\u003c\/strong\u003e This is a performance kit with calibration and hardware components.
