Here is a good site to compare different Procharger supercharger outputs and pulleys and projected boost. Fun to play with.
http://zero2sixtymotorsports.com/pro...st-calculator/
Unfortunately it doesn't have the M4 supercharger listed.
With these big blowers, output is not linear. They are relatively inefficient at lower blower rpm's in making boost. It is a logarithmic increase.
So 3/4 rpm is not 3/4 cfm and hence boost. 36,789/48,000 x 2500cfm -- Does NOT equal 1916cfm but something much less.
It will also depend on your choice of TB/carb, intake manifold, heads, cam and all their flow ratings.
I suspect your pulley combination will possibly yield lower boost numbers than you think especially if all your other components are optimized.
No big deal, So you will just need a smaller SC pulley to achieve your boost target.
Procharge is playing is safe and very conservative. "Start low, Go slow" and proceed from there.
What kind of power do you expect?
Predictions--> 555 CID x 1.15hp/cid = 640hp x 8pounds boost(8/16) = 950hp, x 10pounds boost(10/16) = 1040hp if everything is optimized.
So how much CFM is needed for 1000hp?
When will you be building your engine?

My hull currently runs 68 mph on approximately 350 hp..
As far as the engine, I have it built up to a long block. Just have to find the time to finish it..

I'm running a little over 12 psi on my 540. 9.2-1 cr. Aluminum heads, M3sc blower. I also converted it to COG drive. Holley HP EFI, computer controlled timing, knock sensor, 504 inner cooler, 100° give or take block/water temp. 91 octane. There's to many variables to be able to give you an off the shelf max boost # for your application.
