You have your facts straight. The Procharger builds boost more slowly than a Whipple. At idle, the Procharger essentially has no boost. So, off idle up to "on plane" is much easier on the drives, UNLESS you "hammer it", then you have problems just like a Whipple or BDS blower.
I drive a Formula 252SS, dry weight 4800#, so wet weight is probably around 6000#. But I am running a single HP454-450hp 5# Procharger, so the "drive pressure" is probably greater on my boat than on yours with twins. One thin that is absolutely essential is a Simrek drive shower....no other will do. None of the other brands will, when on plane dump 50 gallons of water on the tower & bearing area. I never have "white stuff" on my drive any more. Nor do I have or ever had any drive problems. Original '93 Bravo !! running 600 hp thru it @ 75mph (gps).
I do not know if you are injected or have carbs. If carbs, send then to Nickerson Performance IMMEDIATELY to get flowed and re-machined. Unbelieveable difference & the turn around time is only 1 week. No soot on transom, no "flat spots", no fouled plugs, etc. All I had to do when mine came back was adjust the idle speed 1/8 turn! & it was perfect. I went from 52mph to 75mph so , you should have no problem making 100, PROVIDED the boat can handle it without chinewalking.
Also, you MUST HAVE external steering for safety! This is a must.
There is a section on Superchargers for sale on "Offshoreonly.com". Also, if you email me a fax # I will send you The Poker Runs America test & comparison article that declares the Procharger type blower is more efficient at higher rpm than the Whipple/BDS?Holley type blowers.Enjoy the new found speed !! email any questions you may have.
Good Luck ! http://free.***boat.net/ubb/smile.gif
