What Procharger Should I Use?
 

Now it is time to buy the prochargers for my twin 1200 hp build.I do not have too much space in the engine area so I am worried about mounting
2 prochargers that will not fit.I am thinking it is best to get a self contained procharger not one that has a oil line going to the procharger,
or would you not agree.Give me your thoughts on what procharger to use.I am thinking about the M3SC or M4SC

I would say M4 but I'm biased... ;)
Not sure about the "SC" may be a better choice


People HAVE done it with an M3 but you'd be wringing the heck out of it..

There was a build on Performance Boats with an M5 and he had issues with lack of boost on the bottom then coming on WAY too hard...

I'm making 1020 hp with 10lbs of boost on a 555 cid engine.. running the second biggest pulley they make .. (blower is spinning 80% capacity)

Could easily do WAY more but my pocketbook just can't support it..

The M3 is to small, M4sc would work well, if you think you will ever want more than 1200 then go with the M5sc. Use the biggest intercooler that will fit your application, just my opinion.

What does your engine builder recommend? What will he warranty? That is the one I'd use.

Here you can see my space.I am worried about how the procharger goes to one side always, when you see it installed it is always going over to the right side and this will be a problem for the port side instalation because to the left there is not much space. Can you get a procharger bracket that moves the parts to the left side?

Looks like you should leave it alone.

But I have to do it,
2 x 800 hp carbureted is nothing like 2 x 1200 fuel injected. Roots to procharger change- power more efficient, less iat heat, less fuel use and more benefits to go faster and be more reliable

I ran Prochargers, I loved them, doubt you'll save fuel just go a lot faster. You'll want to run the M5 intercoolers, have fun !
