SDCE and a Smaller Blower Pulley I am currently running the SDCE with a 3.4 blower pulley.
Does anyone make a smaller pulley like a 3.2? Any other option to get my boost up from 7#?

hmmm I wonder if they use a smaller crank pulley now?
I could have sworn when I had mine a few years ago a 3.4 would have just about maxed out the blower by 6000rpm.
well yah it sounds like you need a 3.2 then.
ASP can make it for you if you can't find any used ones.

7000rpm and 3.4 with the 7.25 SDCE crank is about max for a D1SC (62K max).
A P1SC-1 is rated at 65K so at 6500rpm a 3.2 pulley will just be fine. Even though after 58-59K or so a P1's peak boost doesnt increase a whole bunch in my experience.

ASP or riechart will make one, may call ATI and see if they sell a 3.2 8 rib. Bob at EPP is a good guy to deal with for ATI parts if you dont want to deal with the friendly staff at ATI

Yep, the 7.65 with a 3.4 would max out my P1 @ 6500. But will it mount up to a ATI Damper?
Then again, I don't thing the belt will clear my EWP. It barely clears now.
But I would rather go with a large crank pulley if it will work.

I am currently running the 7.65 8 rib crank pulley with a 3.7 on my D1 seeing a good 8 and close to 9psi. @ 62-63k Granted you have a bigger motor though., vs my stocker. The 8 rib crank pulley mounts directly to the ATI superdampner, with no problems.

Are you running the SDCE tensioner?
