Supercharged 454 mpi's
 

does anybody have any input they can give me about the success of these motors handling superchargers??i have a 312 fastech that runs about 68 on gps on a good day and really need more speed. i have heard rumors that the motors will not hold up? the boat is great , i don't need much more boat for lake norman but speed is where i need to be. all help and input is greatly appreciated thanks, bill

Motors'll hold up fine.
Keep boost around 4 to 5 pounds.
Keep RPM under 5000.

Go with an intercooled centrifugal or whipple. They all offer good kits (whipple, procharger, vortech).

If your looking for blowers I have a friend that has a complete set of b&M 250 efi blowers for sale that he used on his 36 outlaw. He took them off because he went to bigger cubic inch motors. He had them on 454 mag mpis and had good luck they just have to be set up correctly

set up correctly =durability,horsepower
