SUPERCHARGER THE MERCURY REMAN SMALL BLOCK MOTORS

Do you want big block power but don't want to have all that excess weight and low fuel economy? Whipple can give your 357 Magnum 4V, 383 Magnum 4V and 385 Tuned engines a huge jump in power that will simply outperform nearly all big blocks. Skeptics say, “what about torque?” That’s simple, the Whipple twin-screw type supercharger will give your small block more torque than typical 502ci engines, because of it’s unique design, the Whipple Charger can generate full boost at any rpm, just the touch of the throttle and you have instant power. Other skeptics say, “Well you can’t have low end torque and top-end horsepower!” Yet again, the facts differ, most don’t know that the screw compressor is one of the most efficient superchargers ever built. What does this mean? Massive torque levels that are simply unmatchable while simultaneously producing mind-boggling horsepower. No other supercharger in the world can offer this type of torque down low with the incredible top end horsepower. Who wants to wait for the power when you can have it instantly! 

Whipple, the pioneer in ECM/PCM marine development has over 20 years of experience to build, test and validate ECM/PCM calibrations to give you all the safety features while still giving you the maximum amount of power for long trouble free operation. No other company even offers ECM/PCM calibrations, let alone such a comprehensive and detailed kit for a do-it-yourself style installation. Each system is setup to run a conservative 5-6PSI of boost, 91 octane minimum and works with all factory wiring.
