575 sci power upgrades ?
I'm interestd to know what kind of power upgrades have been done to Merc 575 sci set-ups.
How much boost do they run in the stock / factory configuration ?
Your expereince or redirect to reference info appreciated.

I had a set 575 sci in my Top Gun, From what I understand the best upgrade is to actually reowork the motors a little, different cam, different valves, rockers, etc.. If I remember right the boost is only around 5 - 6 lbs or so, if you go any more you will blow the motor up. My motor was reworked and was getting around 650 - 675 HP with a mild cam.

If you don't mind working with an engine builder that is some distance away from you, Tyler Crockett in Michigan.
