Sounds good Pat, I thought of that but I'd be married to the blue motor the insurance price forever. I hate boat insurance!!! Maybe I should get a price fron JC anyway, Would make my summer longer having it ready when it gets here.

Re: Superboat Speeds ???
 

I hear you on the insurance thing...
I pay $700 on my 24' with the little 310HP/7.4.
I don't want to know how much more after I bolt in my 415HP/502... :rolleyes:

Pat, I'm Paying 650.00 For My Current Boat 232 Baja 454-310 Hp, Year 1998....so I Guess East Coast Is Quite A Bit Higher Than Elsewhere. I Put Call To Insu. For Quote On 525 Hp. Lets See How Much That Is!!!

My best top speed 88.3 on gps. 1980 SUPERBOAT 24 with Gale Banks Twin Turbo
454 Magnum MPI, Bravo 1 30 pitch,Cyborg Trans, light on fuel. I have many photos, and have owned the boat for more than 10 years. There are some old photos if you click on my link.

Maguyvah,
What mods are done to your Mag mpi to run the turbo's?

Re: Superboat Speeds ???
 

The engine is Heavily modified, Forged crank, Manley H beam rods, JE forged 8.0 CR pistons, Dart Iron heads, Manley Inconel valves, Custom ground cam. The stock mercruiser MPI intske was cnc port matched to the Dart heads, the fuel rail was bored out io increase the fuel flow and accept the larger injectors, and the stock cool fuel setup was repaced with an Aeromotive 1000 hp fuel pump and GIANT fuel cooler( same size as a Trans cooler)and all of the fuel lines are 12-AN braided SS to supply sufficient fuel volume.
The ECU was custom programmed by AS&M. I t also has a custom fabbed water to air intercooler, and methanol injection that turns on at boost levels above 15 psi. Obviously with this level of boost (21 PSI) the cyl heads are o-ringed with copper head gaskets, and the block is studded to keep things in place! The best thhing about this boat is it is a wicked sleeper, super quiet around the docks, and with the velvet (CYBORG) drive it is a dream around the docks.
