Hey guys I am new to formula and v-bottom world..coming from a 32 Skater. I purchased Arties 303 with the 454 carbed mags and thinking about adding prochargers. Really dont want to build motors and think the prochargers look cool. The boat runs consistant 70mph with labbed 24 bravos at 5200 rpm. just wondering what yall think about the prochargers and what type HP and speeds i could exspect? what will a 303 run with 500-550hp . thanks for any feedback

I have Prochargers on my 6.2s. No issues. Don't let people scare you, seem to be a lot of haters around here.

my 353 has ran m3's on 502's since 2000 ....motors were freshened last year ......m

Well I don't have much results in the high performance world of boats besides what Mike has told me (offthefront) but i can tell you that 3-5 lbs is NOTHING to worry about on one of these motors.

My twin turbo LS motor camaro street/race car i ran at 22-24 psi and made over 1000 HP to the wheels so about 1200 crank hp.
Still ticking!!
