500efi installing blowers
 

Hey guys just wondering your thoughts on putting blower shop 250 kits on my 500efi motors and going to single dominators. I have a line on a cheap set of brand new blower shop 250 kits. Just wondering what are your thoughts and what all it will require for the swap. Thanks

Im interested in the intake setups

I did it adding Whipples to my 500 efis. If you're running Bravo sterndrives, regardless of Bravo model: XR, IMCO lower, etc. you'll puke them in short order. Mine with the Whipples were app. 690 HP on the dyno at 7 lbs of boost. To get to the right props, gear ratio was changed from 1.5 to 1.36. Chief Performance (Tommy) assembled mine.

i have a set for sale in the power boat swap shop on face book they have been to extrude hone and also have arizona speed and marine throttle bodys on them
