I was just wondering where I can buy procharger pulleys at. I have a 3.85 but I want a smaller one. I will need a 6 rib pulley, but if would be cool if someone mad a 8 or 12 rib conversion for my truck. I dont think there is anything out there like that.

I bought my procharger kit used and it had a 3.6 or 3.65 pulley on it, don't remember since its been a while. I don't ever plan on going that small so let me know if you want it.

 

How much boost does that small pulley give you?

Couldn't tell ya. I wasn't tuned for it so I just took it easy without building boost until I got a stock pulley. Man was that hard.

 

bob @ epp carries them as well...if you want new ones...I don't know about the D1SC's, but for the P1SC, the pulley breakdown is as follows...
per ATI:
4.0...8#
3.7...10#
3.6...11#
3.5...12#

 

I have the D1SC and I have a 4.0 pulley on mine and it is makeing 10 lbs of boost.

 

yes...they have different internal components...maybe ranwalk will chime in...I'm sure he has the D1SC pulley breakdown...

 

I have the P1 with a RR 3.6" pulley, which equals about 10 psi on the 5.3. But I have a 6.0 and it makes 8psi. It might make more when it isn't 100* outside. I have a 3.4" which I hope will hit 10 psi.
