    I have seen the sterling "1500's" with and without blower snoot and crank supports. How come some of them have it and some don't? Unless some are setup for higher amounts of boost, shouldn't all of the motors be the same?

    They are overkill for a 1100 hp pleasure boat. I also personally think they are ugly. If you want more power turn up the boost. I prefer shiny and pretty things.

    The PSI Blower is much more efficient than a roots blower. I've run them with 8:1comp. and 12lbs boost with no intercoolers with no problems. Same rotor design as a whipple.

    I've got 47 hours on each of mine, and haven't had any problems or heard any noises. I've added oil to them once, they start to make noise if the oil level is low. They do drink a lot of fuel, but they probably would with 14:71's too. Running 10lbs. boost. 1200/1400hp.
    (and keep an eye on your pulley bolts...they want to come loose)
