SDCE guys in here
i'm positive i wasn't running a shim on the crank pulley ( i have the ATI damper and accompaying SDCE pulley) and i don't think i had any shims under the blwer pulley.
i guess if you need to shim it , just make sure its shimmed out enough so as the belt doesn't touch the bracket.

The problem is that i got the SDCE setup and kept my ATI pullies which are the 7.65 and 4.25. When we installed the SDCE setup the belts dont line up at all. SDCE told us we have to buy their pullies with the shims to get it to line up which just didnt make sense to me. So now im going to have to buy the pullies just to find out what the shim size is and most likely im going to use my 7.65 crank pulley instead of their 7.25 pulley!
I dont want to run a 7.25 pulley because if i wanted to max the D-1SC at 6400RPM i will need a 3.2 blower pulley which is too small. A 7.65 at 6400RPM would need 3.4 to max the blower.
Did anyone run 3.2 blower pulley with SDCE setup successfully with no belt slippage?

Nope this will net you 59,962 impeller speeds at 6500 engine rpms. Your not maxing the blower yet.. a 3.3 or even a 3.2 blower pulley, though might give more slip because your running smaller pullys, but will max out your D-1SC.
I'm running a 8" Crank and a 3.4" blower pulley myself..
Also, you don't need to buy their pulleys to line up the belt correctly.. Just shim it out yourself with nice washers.. ..

I have a 3.0 on the way.

I'd say call SDCE if you can't get the answer here. Or you can just measure the offset and pick up/make a few shims to try out.

I have 8.5 crank pulley laying around here. I used that wih 4.25 and saw 10-11psi, but then i got belt slippage with my ATI setup. If i can fit that 8.5 there it would be awsome. All i need is a 3.6 blower pulley and i will max out the D-1SC.

So from what im seeing here... There are no shims with the blower pulley and the crank pulley. Is it true that the crank pulley diminions on the ATI crank pulley is different than the SDCE crank pulley? I mean an 8 rib is an 8 rib and i dont see how they can be different other than the diameter.
I run a shim on my blower pulley.
I also run the SDCE crank pulley with a 3.1 pulley. I don't have any belt problems at 62k on the blower.
I would recommend getting a belt alignment tool and determining your own shim size. Every car/setup is different.

As we stated in our phone conversations on Friday, ATI made their 8 rib set up AFTER we made our spring tensioner so we have no idea how to line up their crank pulley with our tensioner. Can our tensioner be lined up with theirs? Probably. Will you have clearance issues? Maybe.
And we simply suggested you purchase our crank pulley to save yourself some time and aggravation - we know our setup works, we know how to help you when you have questions with it, and we can send you the correct pieces to go with it. That is why we don't like selling it separately - we've sold our system minus our crank pulley 3 times so far, and all 3 called to order the crank pulley after they had difficulties trying to line up their setup......
