MerCruiser 454/502 Magnum (carbureted)

MerCruiser HP 500 and older HP motors (carbureted)

454 and 502 Magnum engines are excellent candidates for supercharging. This is due not only to a moderate compression ratio, but also very rugged components: forged pistons, a steel crank, and a four bolt main. With an Intercooled ProCharger system, there is no need for internal engine modifications prior to supercharging, and power gains of 45-65% are typical with stock motors running pump gas. Aftermarket parts are also plentiful, and for modified applications, power gains can safely exceed 100% with operation on pump gas*. ATI has safely produced over 1,200 hp on modified Magnum and similar motors.
