best i have run is 107 on gps in my 38 AVS. merlin 540's with m4 prochargers. 30 pitch labbed bravo 1 props. i have imco sc drives and keep blowing them up. i am going to put imco scx uppers with my sc lowers. rite at 1000hp a side. i have talked to a guy in chicago with same set up in a 42 fountain and he is running 13-15 lbs. of boost. i have been running 5. so i will be using his set up with the new drives and sholud break 110-115. also have stelling extension boxes

What power did u have before 540s procharger?

575sc ran 86

my 38 avs has 565 ci motors 1050 doms 805 hp on the dyno best it ran was 96 mph detuned a bit to keep the out of the danger zone runs a strong 93 all day probably around 765 hp guessing no extension boxes it is freakin awesome

So 572/650 85/88 should be possible?

ya you should be right there if you hit 88 you will be impressed in any water these boats rock

are you reworking the engine hatch or is it raised already??

Should be plenty of room, aspirated motors[ATTACH=CONFIG]510249[/ATTACH]
