454 MAG (350/380 HP)

MerCruiser 454/502 Magnum (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.

  • Undisputed maximum power gains
  • Only intercooled centrifugal available for carbureted applications
  • Revolutionary self-contained M-1SC and M-3SC models available as upgrade
  • 3-year warranty available, most durable superchargers
  • Coolest charge air temperatures
  • More experience with carburetion than all other centrifugal manufacturers combined
