BUT belt slip is a BIG issue when pushing for much over 12psi.
Unfortunately hardly anyone makes a pulley setup for a fully optioned (A/C, PS, etc) street Mopar application that will hold anything passed 10-12psi.
There are a few Cog Drive systems out there that will hold some serious boost but built only for LA based small blocks and limited accessories
Yes, belt slippage is an issue. Ya gotta runem TIGHT!! Per Procharger, with very little or no belt tensioner free play.
you can buy a kit for a BBC and make it work for about 1/2 what a mopar kit would run. AMHIK.

Pretty cool.
That was interesting to watch for a bit. Looks like you got stuff sorted out! When I left it was making 5-6psi and 500+tq at 3K.
Gonna be a wild ride.
BIG BIG thank you to Rob for bailing me out once again. Our fuel pressure guage in the dyno room broke and I needed it to reference our dyno digital guage so Rob ran home and found me one and brought it back so we could continue.
Much much appreciation Rob...thank you!
No problem. Any time.
It was cool to see it running.

If you stay under 20 psi, the rib belts system will work - if you keep it tight. With a 4" pulley, I can make 15 lbs of boost @ 5K and over. 3.7" blower pulley can get you over 20 lbs, but belt tension and slippage becomes an issue. I run a much bigger carb than the OP. Simply because my 950 Prosystems carb was on my NA motor and when I went blown, I just sent it back to them for blow through Mods. Came back with very large annular boosters, so I'm sure it doesn't flow 950 CFM anymore.
Fastest 300

Would a cog belt system be the answer or is there a reason why I don't see it being commonly used?
In all the pics I see of these setups it appears the blower hangs a long ways away from the motor- like out to the fender aprons- is there a reason why it's out there so far?
Biggest 2 problems is clearance in front of the engine and COST of the pulleys and Belt.
I've been working on a Cog drive for mine (off & on) and a 55mm pulley adds 2.5-3 inches to the front of the engine at the crank and everywhere else you need a pulley. As well as the S/C itself.
The Belts are pricey if you don't know where to go. Usually $150+ each through the usual suppliers. I got mine for $80 through a local Industrial Supply house. Took Vortech's Base P/N and cross referenced it through Gate's own belt finder and got the Length I needed which was a Little longer than what Vortech had to offer.
Reason you see many of them hanging out the side is most Bracket kits were made for an application that accommodated full accessories. and May not have even been for that particular motor. Or even the route I thought I was going to have to go and move the S/C out to accommodate the length of the available belts.

They going to supply new Main Bearings and a S/C rebuild with that advice?
I have seen more than a FEW with pre-mature main bearing and S/C pulley shaft wear from tightening all the play out of the belt and pulleys.
The side load on the crank and the S/C itself become an Issue.
On a Race Car I say go for it!!!! You will have it apart and freshened at the end of the year anyways. Probably not going to hurt anything.
BUT a street rod????

Pump gasser, flat tappet 410 with a d-1sc procharger/water injection.
Made 720HP@ 5400rpm and 743TQ at 4900rpm! Here's a quick pick.
Still on the dyno, we changed to a larger pulley to slow it down (made 15+psi with the belt slipping) and ended up with 685HP@ 6900rpm and 680TQ with only 13psi.
Doing another similar 318 stroker with same blower setup in 3 weeks and another identical 318 stroker blown build after that. Blowers are fun fun!
Good stuff Brian  Do you have an xtra large A/C system in there, the temps have been brutal down your way.

I wish there was more of these centrifugal blown small block posts- there's hardly any out there to reference. I keep staring at my solid roller 439 W5 on the stand thinking it might be better off as a hydraulic roller with a F1-r or F2. More power/easier on parts/less maintenance/etc...
Other than the money it seems like a no-brainer 
T3 twin turbos Rick, twin turbos. 
Great info in this thread from everyone. My big 318 turbo plan is on the backburner 'til a turbo comes available (draw-through system). 
I hear ya' Griz, if it wasn't for all the plumbing on the turbo setups and the fact I can't seem to own a car that the engine stays together for more than 1 season I would do exactly that.
My supercharged Cobra is a blast to drive with it's roots style blower so I definitely have been bitten by the blower bug.

Can you elaborate on that a little? I have seen you mention it before, but am curious to know what parts would cross over and what has to be changed/modified?

The crank pulley has to be drilled out for a Mopar crank, of course since it's not symmetrical (bolt holes) it cost a tad more. The main mounting bracket has short tabs on it, if you cut and add metal they can easily be mounted to the PS pads. (my main bracet was steel not aluminum) however you can always make a template w/ ply wood and have whatever you want cut and drilled at a local machine shop for WAY less than a "kit" I took the crank pulley to a machine shop and my template to my dads, where he cut and welded it. A quick grind and paine and it looked factory. The machine shope drilled the crank pulley and madea aluminum spacer so it would fit well in the 2 grove pulley. Then it's just a matter of lining everything up. For the back support I added a 1/4 piece of steel, I cut it, heated it and bent it to fit. I did have the discharge tube cut/welded at a shop. I had about $2200 in my set-up including new fuel system, carb prep, gauges and bungs.
