That setup will probably get you into the low 70's. Is that going to make you happy enough?

Did you ever hear the saying "If it's got BOOBS, or BLOWERS, you WILL have problems with it"?

We had the opportunity to add prochargers to our boat at a good price. After reading and listening enough we decided that we wanted reliability more than speed. We chose not to do anything. If we do anything it will be swapping engines for a set of 572's

I'll echo sonic - I decided to hold off and start saving for/building a pair of 540s since they should be much more reliable. As you know nothing is guaranteed when you are playing the HP game though. Basically I chose to wait for the power bump vs. buying the easy bolt on HP that is cheaper now. Good luck on the decision. If you do bolt them on post a few pics.

Reliability and blowers can work together. You just have to know what your doing and build it right.


I am running huffers and they are turn key and push me over 100mph in my Dominator. Just gotta set them up right from the word go.

People get these bad impressions of boosted motors I think from people who are under the impression that you can just buy these kits and bolt them on and go. I think that is a recipe for disaster. A motor has to have the right internals and be set up to handle boost what ever kind it is if it is not set up right as DS mentioned yes you will have reliability issues. Now with that being said as soon as you start make more HP lets say over 525 things will begin to ware differently and more maintenance is required its just as simple as that.

I'm at about 700HP per motor and the only problem I have is she runs a little fat so new plugs are in order every other season. But I would rather have it run a little fat then too lean and pop a motor.

Granted I am only at 56 hours since the motors were built back in the fall of 2005. :rolleyes:

Sounds like I have been on your boat for 10-20% of its total hours from '05-'07. You aren't using it enough Scott!!! :laugher: Actually that is quite a few hours per season.

My 383 destroyed its stock harmonic balancer at the end of last season which wasn't discovered until this season. It is now replaced with a Romac and I can now start using my boat again. I have even less hours on my boat over the 06 & 07 seasons than you do as the Cobra drive was being replaced by the Bravo. I hope to put 30-50 hours on my motor this summer.

Yeah, but those are probably the best 56 hours of your life. :cool:
I know that my hours on his boat were great. You can't beat a 60+ mph CRUISE over 3 footers and then some amazing 95+ mph BLASTS. It is fun to watch other boat try to keep up.

DYNO DYNO DYNO is all I got to add here. Then weld a nub in the exhaust for an oxygen sensor to fine tune in the boat. Only way to be sure the engine is running at the ban on proper air fuel ratio. And thats the most important !!

I agree 100% with CJ, the only way to get them perfect is on a dyno and a water test. I had a 700hp blower motor and it was loads of fun but........I go boating to relax and all I did was watch the gauges, never really enjoyed it. Even on a reliable blower motor theres no room for error. an injector goes bad or just gets plugged youre screwed, water in the gas youre screwed, a little voltage spike and your fuel pump skips a beat...youre screwed, not to mention drive issues. I had pyrometers in my and they used to scare the crap out of me every time I opened the thing up, even though the plugs always looked good when you see the egt's rising around 1350-1375 it would make me CRINGE!

that "CRINGE" feeling is what keeps our engines together if you ask me. Means we are aware of how hard things are working back there.

Once I get mine dieled in perfect, I won't worriy about the engine as much as the drive. And that worry will intern help the engine, cause I won't 'beat' on it.
