Thanks for the feed back.

Does anyone know if you have to throw the ecu, fuel pump and regulator out from vortech like you do with procharger.
I looking for the better out of the box system. Vortech claims you can also keep the stock thermostat for the cool fuel, procharger you have to change it.

You first have to have some sort of idea on what power its going to make.... from there, you base the injector size, fuel pump, lines, reg, off that power number. Then find someone (that knows what there are doing and stands behind their work) that can tune the MEFI system....... or get a FAST XFI or BigStuff3 system and have that tuned

Thats doing it the correct way

It doesn't matter whether Vortecs or Prochargers head unit is pumping your air into the motor, when you get rid of the thermostat and run the motor around 100 degrees vs 140 you are able to run more timing and more boost and subsequently make MORE hp from same cu inches and octane so this is a GOOD thing. As far as "throwing away" Prochargers ECU, never heard that they supplied a ecu?? The best way and ONLY way to have a well tuned efi suprchargerd motor is to have it tuned on your actual motor, this can be done on the water but it needs to be done, Smitty

I used the stock procharger M-3 set up on a 25 Eliminator Eagle except that I ran the fuel return from the rails back to the fuel tank instead of it returning right in front of the Aeromotive fuel pump.
My conclusion:
I liked the procharger feel of power and became a fan of the centrifugals.
I had a light boat and I can tell you that if you look at people's posts, it is those that have heavy boats who break the bravos. People with light boats seem to be able to get away with it.
The way of increasing the fuel to the engine with the boost sensitive fuel pressure regulator on the stock ECM is not the right way to do it. I think that the lighter your boat the less this makes a difference. Like was mentioned before in some good posts you absolutely need a custom ecm tune. You will need a bung in the exhaust for the sensor while tuning. I'm not saying that the stock system won't work because it did for me, but it would be money well spent to have the ECM custom tuned then you can forget about reading plugs and know that the A/F ratio is right in all RPM/Load ranges.
Internally new cometic head gaskets, and valve train upgrade is the right thing to do.
Mounting the intercooler is typically a big compromise in esthetics.
The stock oil cooler is marginal on the HP level you will be at.
Hydraulic steering is a must.
Up grading your guage package to include fuel pressure and water pressure is a must.
If you do it right it will be a nice package. If you don't you have to depend on luck.

Your system has to be one of the nicest set ups I have seen for a pro charger. Although the gimbals could be the weak link on Lake Michigan. See you this summer.

I'm on my second boat with Prochargers, M-4's 1100+ hp, no problems. I don't know where the story of them being hard on drives came from, my Baja had XZ never blew one. I like the way the power comes on.

Thanks,
Yes, the gimbals are a weak link. Broke one a year back at over 100+ mph,it was not pretty. Drive was only left attached by the tie bar, made for a long day. Schumaker Performance is one of the few engine builders I know that builds a great fuel injected pro charger motor.

I guess i don't understand the ecu part, the vortech comes with a programmed ecu and a map sensor. This replaces the existing ecu correct? If so is it any good?

Thanks
