Their "guesstimates" are a little inflated but close...

Do you have the box or whatever i need for the carb.Or do i have to change my carbs.I hope these aren't stupid Q.thanks craig.

I listed this for a friend of mine you can give him a call and he could answer all of your questions at 847-294-1195 his name is Tom. Thanks

I have the carb box and some tubing.....contact the seller and grab what he has and we can work out the rest....

Fogducker do you think this would work well with my motor or am i asking for trouble.I have 400 already do you think this could bring me up to 500

I am running the same setup on a 454 built for it.(low compression with a balanced steel bottom end and a full roller valve train) How much boost are you wanting to run. You can go up to 9 lbs.

How much compression do you have????

As Pachanga pointed out, your current compression is going to dictate if it is a wise install.

I do not know a great deal about motors but I am learning.....I am right in the middle of a rebuild with a Procharger install, 454Mag EFI total rebuild with about 8.75:1 compression. M-1SC Procharger planning 5lbs boost.

I have been told if you have high compression a Procharger is not a good idea, I was also told the secret to running a Procharged engine is to carefully monitor the gauges!!!

Fuel pressure, water pressure and engine temp.....better to run rich as opposed to lean.....

The other thing I was told was the ECM should be reprogramed specifically to the motor, DO NOT listen to Procharger when they say that reprograming is not required......

Dollar for dollar a Procharger is a good way to get some extra hp......but do your homework....

You will also need a fuelpump setup with the blow through carb set up. As boost increases so must your fuel pressure. If you do not do this the more boost you have the less fuel pressure you will have leading to a major leanout. You should run boost and fuel pressure gauges and make sure your fuel pressure increases pound for pound with the amount of boost you have. I run mine much richer than needed...I could probably tune on a dyno and gain at least 100 horses on my set up but wanted conservative power with not quite so many worries.

Thought I would add more thoughts.

1st I will say I am not an engine guru but have some experience. I did the neccesary research for my application and bought the proper set up for my application.

You will have more boost than advertised if you use a big block set up. The more cubes then less boost. So you will have more. It's all about volumne and flow.

A "good" set of forged pistons is a must if you go with much boost.

Dialing one in is a pain in the ass unless you have a dyno setup with the needed equipment. Mainly air to fuel ratios. If you are cautious you will start out with fat jets in your carb. BTW procharger recommends a 650CFM on a 454! This has something to do with fuel atomization or flow distribution. I have a 30 over 454 and it does fine. I started with 102 jets in the back and 82's in the front. If you don't dyno you have to just start hitting and missing to a degree. Slowly come down on your jet size gauged by reading your plugs.

Procharger recommends running the engine(alias your boat) wide open and shutting it down. Then pull the plugs and read them. I didn't want to do this. I just came down on my front jets until I could idle around without fouling plugs. I am also running 9lbs of boost so I am cautious! I was mainly afyer the thrill of the midrange romp! Now that my low end jetting is right I am sure I could destroy my bravo in a day.

I was after a dependable 600HP...which I think I have probably a little more but don't even know if I have 600. But my Pachanga 22 will surprise the bassboats with the big outboards hanging off the back!

Do your research!

Thanks for all the great advice.I talked to my mechanic and I do have a high comp.so now i think i'm going to look into a blackhawk drive for next summer.that should give me some more top end.I have a alpha now running great.or should i look for a alpha ss.
